The Power of the Ocean: A Comprehensive Guide to Organic Fish Fertilizer for Plants

For centuries, the earth’s most skilled cultivators have understood the profound connection between healthy soil and robust plant life. In the quest for sustainable and nutrient-rich amendments, organic fish fertilizer stands out as a time-honored, incredibly effective solution. Derived from a natural, renewable resource, fish fertilizer offers a holistic approach to plant nutrition, simultaneously feeding your garden and enriching the very foundation upon which it grows: the soil. This comprehensive guide delves into the science, types, benefits, and best practices for incorporating this oceanic marvel into your gardening regimen, empowering you to cultivate vibrant, thriving plants through nature’s own bounty.

Unlike synthetic chemical fertilizers that often provide quick but fleeting boosts and can degrade soil health over time, organic fish fertilizer works in harmony with the ecosystem. It delivers a balanced spectrum of nutrients in a slow-release form, fostering long-term fertility and supporting a thriving microbial community beneath the surface. From ancient indigenous practices of burying fish carcases in planting mounds to modern enzymatic hydrolysis techniques, the principle remains the same: harness the rich biological material of fish to nourish life above ground. As gardeners increasingly turn towards environmentally conscious methods, understanding and utilizing organic fish fertilizer becomes not just a choice, but a cornerstone of regenerative cultivation.

What is Organic Fish Fertilizer?

At its core, organic fish fertilizer is a nutrient-rich product derived from various parts of fish, including fish waste, trimmings, and sometimes whole fish that are unsuitable for human consumption. It undergoes processing to make its valuable nutrients available to plants. The “organic” designation is crucial, meaning it is processed without synthetic chemicals and adheres to standards that promote ecological balance and sustainability. This commitment ensures that the final product is not only potent but also safe for your plants, soil, and the wider environment.

The origins of using fish as a soil amendment are deeply rooted in agricultural history. Coastal communities and indigenous peoples across the globe have long recognized the fertilizing power of fish, incorporating it into their farming practices for generations. This traditional wisdom has evolved into modern organic gardening techniques, where fish fertilizer is celebrated for its ability to provide a complete nutritional profile that encourages vigorous growth, strong root development, and bountiful yields. It represents a cyclical approach to resource management, transforming what might otherwise be waste into a valuable asset for food production.

The Science Behind Fish Fertilizer: A Nutrient Powerhouse

The efficacy of organic fish fertilizer lies in its complex composition, which goes far beyond a simple N-P-K (nitrogen, phosphorus, potassium) ratio. While it provides these essential macronutrients crucial for plant survival and growth, it also delivers a wealth of secondary macronutrients, micronutrients, amino acids, vitamins, and beneficial oils, creating a truly holistic feeding solution.

Macronutrient Profile (N-P-K)

Nitrogen (N): Fish fertilizer is particularly rich in nitrogen, a cornerstone for vegetative growth. Nitrogen is a key component of chlorophyll, the green pigment responsible for photosynthesis, and is vital for lush foliage and strong stem development. The nitrogen in fish fertilizer is predominantly in organic forms (proteins and amino acids), which are slowly broken down by soil microbes, providing a steady, sustained release that minimizes the risk of nutrient leaching and over-fertilization often associated with synthetic quick-release nitrogen.
Phosphorus (P): Essential for robust root development, flowering, and fruiting, phosphorus plays a critical role in energy transfer within the plant. Fish fertilizer supplies phosphorus in forms that are readily available to plants, supporting healthy cellular division and the formation of seeds and fruits.
Potassium (K): Known as the “quality” nutrient, potassium contributes to overall plant vigor, disease resistance, and efficient water use. It helps regulate various metabolic processes, strengthens cell walls, and improves a plant’s ability to withstand stress from drought, pests, and disease.

Micronutrients and Organic Compounds

Beyond N-P-K, fish fertilizer provides a comprehensive array of vital micronutrients such as calcium, magnesium, sulfur, iron, manganese, zinc, copper, boron, and molybdenum. These elements, though needed in smaller quantities, are indispensable for specific enzymatic functions, photosynthesis, and overall plant health. The presence of these trace elements helps prevent deficiencies that can stunt growth and compromise plant immunity.

Furthermore, fish fertilizer is unique due to its high content of amino acids and proteins. These organic molecules are the building blocks of life and contribute significantly to plant health. When applied to the soil, they serve as a direct food source for beneficial soil microbes, enhancing their activity and proliferation. This microbial activity is crucial for breaking down organic matter, making nutrients available to plant roots, and improving soil structure. Some amino acids can also act as chelating agents, binding to micronutrients and making them more accessible for plant uptake.

The beneficial oils and enzymes present in certain types of fish fertilizer further enhance its value. These components contribute to soil conditioning, helping to improve soil tilth, water retention, and aeration. The combination of readily available nutrients and slow-release organic matter ensures that plants receive continuous feeding while the soil ecosystem is simultaneously nurtured and built up.

Types of Organic Fish Fertilizer: Choosing the Right Form

Organic fish fertilizers come in several forms, each with distinct characteristics, processing methods, and ideal applications. Understanding these differences is key to selecting the most appropriate product for your specific gardening needs.

1. Fish Emulsion

Fish emulsion is perhaps the most widely recognized form of liquid fish fertilizer. It is typically produced by cooking fish byproducts and then pressing the mixture to separate the oils and solids. The remaining liquid is then concentrated. This heating process, while effective for breaking down fish material, can sometimes reduce the concentration of certain delicate nutrients, amino acids, and beneficial oils.

Characteristics: Fish emulsion often has a distinctive and strong “fishy” odor, which can be a deterrent for some gardeners. It is usually brown in color and, once diluted, is easy to apply as a liquid drench or foliar spray. Its N-P-K ratio is generally lower (e.g., 5-1-1 or 2-4-0) compared to raw fish material, reflecting the loss of some nutrients during processing.
Applications: Fish emulsion is a versatile all-purpose fertilizer suitable for a wide range of plants, including vegetables, flowers, trees, and shrubs. It provides a relatively quick boost of nitrogen, making it excellent for promoting vegetative growth. It’s particularly useful for feeding young plants and seedlings.

2. Fish Hydrolysate

Often considered a superior form of liquid fish fertilizer, fish hydrolysate is produced through a cold enzymatic digestion process. Instead of high heat, enzymes are used to break down the fish into a liquid suspension. This method preserves a broader spectrum of nutrients, including delicate proteins, amino acids, vitamins, hormones, beneficial oils, and even some beneficial microbes, that might be denatured or lost during heat processing.

Characteristics: Fish hydrolysate typically has a less pungent, though still noticeable, odor compared to emulsion. Its appearance is often thicker and richer, sometimes containing fine particulates, as it retains more of the original fish material. Due to the gentler processing, it offers a more complete nutrient profile and is considered more “alive” with beneficial compounds. The N-P-K ratios can be similar or slightly higher than emulsions, but its true value lies in the biological complexity.
Applications: Fish hydrolysate is highly beneficial for enhancing soil biology, promoting vigorous root development, and improving overall plant health and resilience. It’s excellent for all plant types and is particularly valued by organic growers looking to build long-term soil fertility and microbial activity. It can be used as a soil drench, foliar spray, or as an ingredient in compost teas.

3. Fish Meal

Fish meal is a solid, granular form of fish fertilizer. It is made by drying and grinding fish parts into a powder or pellet form. Unlike liquid fertilizers, fish meal provides a slow-release source of nutrients as it must be broken down by soil microorganisms before its nutrients become available to plants.

Characteristics: Fish meal has a much milder odor when dry, though it can become more noticeable when wet or actively breaking down in the soil. It typically has a higher N-P-K ratio than liquid forms (e.g., 10-4-0), especially high in nitrogen and phosphorus. It also contributes significant organic matter to the soil.
Applications: Fish meal is ideal as a pre-plant soil amendment, worked into the garden beds before planting. It can also be used as a side dressing for established plants, providing a long-term, steady supply of nutrients. Its slow-release nature makes it excellent for building sustained soil fertility and encouraging beneficial fungal and bacterial populations. It is also a good option for deterring burrowing pests due to its smell when first applied and mixed into the soil.

When choosing between these types, consider your immediate needs (quick boost vs. long-term feeding), odor tolerance, and specific goals for soil health. Many organic gardeners incorporate a combination of these forms for a comprehensive nutrient management strategy.

Transformative Benefits for Plants and Soil

The consistent use of organic fish fertilizer delivers a cascade of benefits that profoundly impact both plant vitality and the long-term health of your garden soil. Its holistic nature ensures that it doesn’t just feed the plant, but also nurtures the entire ecosystem supporting it.

1. Enhanced Plant Growth and Vigor

Lush Foliage and Strong Stems: The high nitrogen content, particularly in its organically bound form, promotes robust vegetative growth, leading to greener, more luxuriant leaves and stronger stems capable of supporting heavy fruits and flowers.
Superior Root Development: Phosphorus and the array of amino acids encourage the proliferation of strong, healthy root systems. A well-developed root system is crucial for efficient water and nutrient uptake, anchoring the plant, and increasing its resilience against environmental stressors.
Improved Flowering and Fruiting: The balanced N-P-K and micronutrient profile supports all stages of plant development, including the transition to reproductive growth. This often translates into more abundant and higher-quality blooms and increased fruit and vegetable yields.

2. Improved Soil Health and Fertility

Feeds the Soil Food Web: Unlike synthetic fertilizers that bypass soil biology, fish fertilizer acts as a direct food source for beneficial microorganisms, fungi, and earthworms. This stimulates microbial activity, which is essential for nutrient cycling and soil structure improvement.
Increases Organic Matter: As fish fertilizer breaks down, it contributes to the organic matter content of the soil. Organic matter is vital for improving soil structure, enhancing water retention, and buffering against pH fluctuations. Over time, this leads to richer, more friable soil that is easier to work and more productive.
Better Nutrient Cycling: The microbial decomposition of fish fertilizer releases nutrients gradually, mimicking natural processes. This slow release ensures a steady supply of nutrients to plants, reduces leaching into waterways, and contributes to a sustainable nutrient cycle within the garden.

3. Increased Microbial Activity

The living components and complex organic molecules in fish hydrolysate, especially, are magnets for beneficial soil microbes. These microorganisms perform invaluable services, including:

Nutrient Conversion: Breaking down complex organic compounds into forms that plant roots can absorb.
Disease Suppression: Competing with and suppressing harmful soil-borne pathogens, creating a healthier root environment.
Humus Formation: Contributing to the creation of stable humic substances, which are crucial for long-term soil fertility.

4. Enhanced Disease and Pest Resistance

Plants nourished with a complete spectrum of organic nutrients from fish fertilizer are inherently healthier and more resilient. Stronger cell walls, balanced nutrient uptake, and a thriving root system make plants less susceptible to common diseases and pest infestations. A healthy plant can mount a more effective defense against stressors, reducing the need for chemical interventions.

5. Environmentally Friendly and Non-Toxic

As an organic product, fish fertilizer is safe for use around children and pets when applied correctly. It does not introduce harmful chemical residues into the soil or food chain, making it ideal for edible gardens. Its use supports sustainable agriculture by recycling fish byproducts and reducing reliance on fossil-fuel-intensive synthetic fertilizers, thereby minimizing environmental impact and promoting biodiversity.

Mastering the Application: How to Use Fish Fertilizer Effectively

To maximize the benefits of organic fish fertilizer, proper application techniques, dilution rates, and timing are crucial. While specific instructions may vary by product, these general guidelines will help you effectively integrate fish fertilizer into your gardening routine.

1. Understanding Dilution Ratios

Always read and follow the manufacturer’s instructions on the product label. Over-fertilization, even with organic products, can lead to plant stress. General guidelines:

General Purpose (Soil Drench): Typically 1 tablespoon (15 ml) per gallon (3.8 liters) of water for established plants.
Seedlings and Young Plants: Use a weaker solution, around ½ to 1 teaspoon (2.5-5 ml) per gallon of water, to avoid overwhelming delicate root systems.
Foliar Feeding: A more dilute solution, often ½ to 1 tablespoon per gallon, is recommended to prevent leaf burn.

Mix thoroughly before application. For granular fish meal, follow package directions for incorporation rates per square foot or into planting holes.

2. Application Methods

Soil Drench (Most Common):
Dilute the liquid fish fertilizer in water and apply it directly to the soil around the base of your plants. Aim to saturate the root zone. This method ensures nutrients are delivered directly to the roots and become available through microbial action in the soil. It’s effective for all plant types and provides consistent feeding.
Foliar Feeding:
For a quicker nutrient boost, especially for stressed plants or those exhibiting nutrient deficiencies, a diluted solution can be sprayed directly onto plant leaves. Leaves can absorb nutrients more rapidly than roots. Apply in the early morning or late evening when temperatures are cooler and the stomata (pores on leaves) are open, and direct sunlight is less intense, to prevent leaf burn and maximize absorption. Ensure good coverage on both the top and underside of leaves.
Pre-Planting Soil Amendment (for Fish Meal):
Before planting new garden beds or containers, incorporate fish meal directly into the soil. Spread the recommended amount evenly over the soil surface and gently work it into the top 4-6 inches. This provides a slow-release nutrient reservoir for plants as they establish and grow.
Side Dressing (for Fish Meal):
For established plants, sprinkle fish meal around the drip line (the outer edge of the plant’s canopy), avoiding direct contact with the stem. Lightly scratch it into the soil surface and water thoroughly. This provides a gradual nutrient release over several weeks or months.
Compost Tea Additive:
Fish hydrolysate can be a powerful addition to actively aerated compost teas. It provides a rich food source for beneficial microorganisms, boosting their numbers and diversity, resulting in an even more potent microbial brew for soil and plant health.

3. Timing and Frequency

Active Growing Season: Apply liquid fish fertilizer every 2-4 weeks during the plant’s active growth phase – from spring through late summer.
Seedlings and Transplants: Use a very dilute solution shortly after germination or transplanting to encourage strong root development and reduce transplant shock.
Before Flowering/Fruiting: A boost of fish fertilizer before plants enter their flowering and fruiting stages can support robust production.
Lawns: Apply liquid fish fertilizer to lawns every 4-6 weeks during the growing season for greener, healthier turf.

Adjust frequency based on plant needs, observed growth, and soil fertility. Less fertile soils may benefit from more frequent applications.

4. Safety Precautions

Gloves and Eye Protection: Always wear gloves when handling concentrated fish fertilizer. Eye protection is advisable, especially when mixing or spraying.
Ventilation: Work in a well-ventilated area, particularly when dealing with fish emulsion due to its strong odor.
Wash Hands: Thoroughly wash hands with soap and water after handling and before eating.
Storage: Store concentrated fish fertilizer in a cool, dark place, tightly sealed, and out of reach of children and pets.
Water In: After applying liquid fertilizer as a soil drench, water thoroughly to help carry nutrients into the root zone and minimize surface odor. When using fish meal, always water it in well after incorporation.

By following these guidelines, you can harness the full potential of organic fish fertilizer to cultivate a thriving and productive garden while maintaining an environmentally responsible approach.

Addressing Common Concerns and Challenges

While organic fish fertilizer offers numerous benefits, a few common concerns often arise among new users. Understanding and addressing these challenges can ensure a positive and effective experience.

1. The Odor Factor

Perhaps the most frequently cited concern is the distinctive “fishy” odor, especially with fish emulsion. While fish hydrolysate tends to have a milder scent, it’s still noticeable.

Mitigation Strategies:
- Apply in the Morning/Evening: This allows the smell to dissipate before human activity peaks and reduces the likelihood of attracting nocturnal animals.
- Water In Thoroughly: After application, water the area well. This helps carry the fertilizer into the soil, minimizing surface odor.
- Bury Granular Forms: When using fish meal, incorporate it several inches deep into the soil.
- Ventilation: When mixing indoors, ensure good ventilation.
- Expectation Management: Understand that the odor is temporary, usually dissipating within a day or two, especially after watering or rain.

2. Attracting Pests and Animals

The organic nature and scent of fish fertilizer can sometimes attract curious animals like raccoons, skunks, cats, dogs, or even birds, who might dig up beds to investigate the source of the smell.

Mitigation Strategies:
- Deep Application: For granular forms like fish meal, mix it thoroughly into the top 4-6 inches of soil rather than leaving it on the surface.
- Water In Liquid Forms: Ensure liquid applications are watered in well to move the scent below the soil surface.
- Physical Barriers: For persistent problems, consider temporary netting or chicken wire over vulnerable areas until the smell subsides.
- Deterrents: Some gardeners use scent-based deterrents (e.g., cayenne pepper, coffee grounds, specific commercial animal repellents) around the treated areas, though effectiveness can vary.
- Timing: Applying during daylight hours and allowing the scent to dissipate before nightfall can reduce attraction to nocturnal animals.

3. Cost Considerations

Organic fish fertilizers can sometimes be more expensive per volume than synthetic alternatives. However, it’s important to consider the long-term value.

Concentrated Form: Liquid fish fertilizers are highly concentrated and require significant dilution, meaning a bottle lasts longer than might initially appear.
Holistic Benefits: The investment covers not just plant nutrition but also soil health, microbial activity, and plant resilience, potentially reducing the need for other amendments, pesticides, or disease treatments.
Quality vs. Quantity: For organic gardeners, the benefits of non-toxic, sustainable nutrition often outweigh the initial cost difference, leading to healthier plants and a more productive garden over time.

4. Storage and Shelf Life

Proper storage is essential to maintain the efficacy and prevent spoilage of fish fertilizer.

Cool, Dark Place: Store in a cool, dark location away from direct sunlight and extreme temperatures.
Tight Seal: Ensure the container is tightly sealed after each use to prevent oxidation and odor leakage.
Shelf Life: Most liquid fish fertilizers have a shelf life of 2-3 years if stored correctly. Fish meal, being dry, can last longer if kept free from moisture. Discard any product that develops an unusually foul smell (beyond the typical fishy odor), mold, or significant changes in consistency, as this may indicate spoilage.

5. Potential for Over-Fertilization (Though Less Common)

While fish fertilizer is less likely to cause nutrient burn than synthetic fertilizers due to its slow-release nature, over-application is still possible, especially with highly concentrated liquid forms.

Dilution is Key: Always dilute liquid fish fertilizer according to manufacturer instructions. Applying undiluted product can burn plant roots or foliage (especially during foliar sprays).
Monitor Plants: Observe your plants for signs of stress. Yellowing or browning leaf tips can indicate over-fertilization. If suspected, flush the soil with plain water.
Balanced Approach: Fish fertilizer is best used as part of a balanced organic feeding program, complementing compost and other organic amendments rather than being the sole nutrient source.

By being mindful of these considerations, gardeners can effectively harness the power of organic fish fertilizer while minimizing any potential drawbacks, leading to a more successful and enjoyable gardening experience.

Comparing Fish Fertilizer to Other Organic Fertilizers

Organic gardeners have a diverse palette of natural amendments at their disposal, each offering unique benefits. Understanding how organic fish fertilizer compares to other popular organic options can help you create a comprehensive and effective feeding strategy for your garden.

1. Fish Fertilizer vs. Compost

Compost: The backbone of organic gardening, compost is an incredible soil builder, improving structure, water retention, and microbial diversity. It provides a broad spectrum of nutrients, but these are generally released very slowly and in lower concentrations compared to fish fertilizer. Compost primarily builds long-term soil health.
Fish Fertilizer: Offers a faster and more concentrated boost of readily available nutrients, particularly nitrogen. While it also feeds soil microbes and contributes organic matter, its primary role is more direct plant feeding.
Synergy: These two are highly complementary. Compost builds the soil foundation, while fish fertilizer provides quick, targeted nutrition when plants need it most, enhancing the overall fertility cycle.

2. Fish Fertilizer vs. Manure

Manure (Composted): A valuable source of N-P-K and organic matter, manure significantly improves soil structure and fertility. However, nutrient content can vary widely depending on the animal source and composting process. Fresh manure can burn plants and introduce pathogens, necessitating thorough composting.
Fish Fertilizer: Offers a more consistent and predictable nutrient profile. It’s generally cleaner and free of weed seeds and potential pathogens found in incompletely composted manure. Fish hydrolysate, in particular, delivers more bioavailable nutrients quickly.
Consideration: Both are excellent organic fertilizers. Fish fertilizer might be preferred for precise nutrient delivery and cleaner application, especially for container plants or during specific growth stages.

3. Fish Fertilizer vs. Kelp Meal/Liquid Seaweed

Kelp/Seaweed: Primarily known for their rich micronutrient content, growth hormones, amino acids, and beneficial trace elements. They are excellent for stress tolerance, improving overall plant health, and boosting microbial activity, but they typically have lower N-P-K values compared to fish fertilizer.
Fish Fertilizer: Provides a higher concentration of macronutrients (N-P-K), especially nitrogen, crucial for vigorous growth.
Synergy: These are a powerful duo. Kelp provides the micronutrient and hormone boost that fish fertilizer might be less concentrated in, while fish fertilizer delivers the primary growth nutrients. Using them together offers a comprehensive nutritional package.

4. Fish Fertilizer vs. Bone Meal/Blood Meal

Bone Meal: A slow-release source of phosphorus and calcium, ideal for root development, flowering, and fruiting. Very low in nitrogen.
Blood Meal: A rapid and potent source of nitrogen, promoting quick vegetative growth. Can easily burn plants if over-applied.
Fish Fertilizer: Provides a more balanced N-P-K profile than either bone or blood meal individually, along with a full spectrum of micronutrients. Its nitrogen is released more gently than blood meal, reducing burn risk, and it offers more immediate availability than bone meal.
Specific Use: Bone and blood meal are useful for targeting specific nutrient needs (P for flowering, quick N for greens), but fish fertilizer offers a broader, more balanced approach.

5. Fish Fertilizer vs. Synthetic Fertilizers

Synthetic Fertilizers: Provide highly concentrated, immediately available N-P-K. They are often cheaper per application and yield quick results. However, they can deplete soil organic matter, harm beneficial soil microbes, and are prone to leaching, leading to environmental pollution. They offer no long-term soil building benefits.
Fish Fertilizer: Provides nutrients in an organic, slow-release form that works with soil biology. It feeds the plant *and* the soil, building long-term fertility and resilience. It avoids chemical residues and promotes a healthier, more sustainable garden ecosystem.
Fundamental Difference: Synthetic fertilizers are a short-term feed for the plant; organic fish fertilizer is a long-term investment in the entire garden ecosystem.

In essence, fish fertilizer distinguishes itself by offering a balanced, comprehensive, and biologically active nutrient profile that not only nourishes plants effectively but also significantly contributes to the health and vitality of the soil food web. It is a cornerstone for any serious organic gardener aiming for sustainable fertility.

Its production and use align well with ecological principles, promoting a more circular and responsible approach to resource management.

1. Resource Utilization and Waste Reduction

A significant portion of organic fish fertilizer is derived from the byproducts of commercial fishing and aquaculture industries. This includes fish trimmings, bones, scales, and other parts not used for human consumption. By processing these materials into fertilizer, waste is significantly reduced, preventing valuable organic matter from going into landfills or being discarded, where it could decompose anaerobically and produce potent greenhouse gases like methane. This transforms a potential waste stream into a valuable agricultural input, embodying principles of a circular economy.

2. Sustainable Sourcing

Responsible manufacturers of organic fish fertilizer prioritize sourcing from sustainable fisheries or aquaculture operations that adhere to strict environmental regulations. This means avoiding fish species that are overfished or employing practices that harm marine ecosystems. When sourced ethically, fish fertilizer supports industries that are working towards more sustainable methods of seafood production, further contributing to ocean health rather than detracting from it.

3. Low-Impact Processing

The methods used to produce high-quality organic fish fertilizers, particularly cold enzymatic hydrolysis for fish hydrolysate, are generally low-impact. They require less energy compared to some chemical fertilizer manufacturing processes and avoid the use of harsh chemicals. This reduces the carbon footprint associated with fertilizer production, aligning with broader goals of reducing energy consumption and pollution in agriculture.

4. Ecological Benefits for Soil and Water

Reduced Chemical Runoff: Unlike synthetic chemical fertilizers, which can easily leach into groundwater and runoff into rivers and lakes, contributing to eutrophication (algal blooms and oxygen depletion), organic fish fertilizer releases nutrients slowly. This slow-release mechanism significantly reduces the risk of nutrient leaching, protecting aquatic ecosystems.
Enhanced Soil Biodiversity: By feeding the soil food web, fish fertilizer promotes a healthy and diverse microbial community. This biodiversity is crucial for soil resilience, natural pest and disease suppression, and efficient nutrient cycling, creating a robust ecosystem that can thrive without synthetic inputs.
Non-Toxic to Wildlife: When applied correctly, organic fish fertilizer is non-toxic to beneficial insects, pollinators, pets, and larger wildlife. This protects the wider ecosystem around your garden, fostering a healthier environment for all living creatures.

5. Contribution to Climate Change Mitigation

By improving soil health and increasing organic matter content, fish fertilizer can contribute to carbon sequestration in the soil. Healthy, organically rich soils are better able to store atmospheric carbon, helping to mitigate climate change.
