Compost manure is one of the most commonly used types of fertilizers in organic farming. It is made by decomposing organic matter like food scraps, leaves, and garden waste. This type of fertilizer is rich in a variety of essential nutrients such as nitrogen, phosphorus, and potassium, making it an excellent all-purpose fertilizer for most types of crops. Compost manure also contains beneficial microorganisms that help improve soil structure, water retention, and nutrient cycling.

Benefits of Compost Manure:

• Improves Soil Fertility: Over time, compost manure enhances the soil’s ability to retain nutrients, promoting healthy plant growth.
• Boosts Microbial Activity: Compost helps foster beneficial microorganisms in the soil, creating a healthier ecosystem for plants to thrive.
• Reduces Soil Erosion: The organic matter in compost increases the soil’s ability to hold moisture and reduces the risk of erosion, especially on sloped land.

Compost is especially useful for multilayer farming, where different crops are grown together to improve yields and reduce pest issues.

2. Green Manure

Green manure refers to crops that are grown specifically to be tilled back into the soil to improve its organic content. These crops, such as legumes (e.g., clover, peas, or alfalfa), fix nitrogen in the soil and release it slowly, benefiting the next set of crops that are planted. Green manure is a cost-effective fertilizer and can be integrated into various farming systems, including intensive subsistence farming.

Benefits of Green Manure:

• Enhances Soil Nitrogen Levels: Green manure crops like legumes fix nitrogen in the soil, reducing the need for additional fertilizers.
• Reduces Weeds: Growing cover crops suppresses weed growth, decreasing the need for herbicides.
• Improves Soil Structure: Green manure helps break up compacted soil, allowing for better water infiltration and root growth.

In multilayer farming systems, green manure can be used to improve the soil quality for crops growing at different levels.

3. Animal Manure

Animal manure is another key ingredient in organic farming. It includes the waste products from livestock such as cows, chickens, and horses. This fertilizer is rich in essential nutrients like nitrogen, phosphorus, and potassium, as well as micronutrients that support plant health. However, it’s important to compost animal manure before applying it to crops to ensure that pathogens are neutralized.

Benefits of Animal Manure:

• Provides Nutrients: Animal manure supplies essential nutrients, such as nitrogen, phosphorus, and potassium, which are vital for plant growth.
• Improves Soil Organic Matter: When decomposed, animal manure adds organic matter to the soil, improving its texture and structure.
• Supports Microbial Life: Animal manure introduces beneficial bacteria into the soil, which helps break down organic matter and make nutrients available to plants.

Animal manure is particularly useful for farms that practice intensive subsistence farming, where the focus is on maximizing crop yields in a small area using sustainable methods.

4. Bone Meal Fertilizer

Bone meal fertilizer is made from finely ground bones, often from cattle or poultry. This organic fertilizer is high in phosphorus, a critical nutrient for root development, flower formation, and overall plant health. Bone meal also contains calcium, which helps strengthen plant cell walls and promotes healthy root systems.

Benefits of Bone Meal Fertilizer:

• Rich in Phosphorus: Bone meal provides a slow-release source of phosphorus, which is vital for root and flower development.
• Promotes Strong Roots: Phosphorus in bone meal helps encourage deep root growth, making plants more resilient to drought and disease.
• Improves Soil Structure: The application of bone meal helps in enhancing the soil’s mineral content, making it more fertile over time.

This type of fertilizer is highly effective for crops grown in intensive subsistence farming where high-yield crops are needed for sustenance.

5. Fish Emulsion Fertilizer

Fish emulsion fertilizer is a liquid fertilizer made from decomposed fish. It’s a natural, nutrient-rich option that is packed with nitrogen, phosphorus, potassium, and essential trace elements. Fish emulsion is typically applied as a foliar spray or soil drench to help boost plant growth.

Benefits of Fish Emulsion Fertilizer:

• High in Nitrogen: Fish emulsion provides a quick-release source of nitrogen, which is essential for leafy green plants.
• Rich in Micronutrients: It contains micronutrients like calcium, magnesium, and sulfur, which help with overall plant health.
• Supports Beneficial Organisms: Fish emulsion improves soil life by promoting beneficial bacteria and fungi that aid in nutrient cycling.

Fish emulsion is ideal for use in multilayer farming where various plants need different nutrients at different growth stages.

Benefits of Organic Fertilizers

Organic fertilizers offer numerous advantages over synthetic fertilizers, making them an essential component of sustainable farming. Below, we highlight some of the key benefits of using organic fertilizers in farming.

Soil Enrichment

Organic fertilizers improve soil structure by increasing organic matter content. This improves the soil’s ability to retain moisture, provides better aeration, and reduces soil compaction. Over time, organic fertilizers enhance the soil’s capacity to support healthy plant growth.

Reduction of Chemical Dependency

Organic fertilizers reduce the need for chemical fertilizers, which can harm the environment and deplete soil nutrients. By using natural fertilizers, farmers can avoid the negative consequences of synthetic fertilizers, such as nutrient leaching into water sources and soil degradation.

Environmentally Friendly

One of the most important benefits of organic fertilizers is that they are environmentally friendly. They help reduce pollution, conserve water, and support biodiversity. They also encourage sustainable farming practices, making them a crucial element of multilayer farming and intensive subsistence farming.

How to Apply Organic Fertilizers

Proper application of organic fertilizers is crucial for maximizing their effectiveness. Here are some tips on how to apply organic fertilizers:

1. Compost and Animal Manure: Apply compost and manure to the soil in the fall or early spring to give it time to break down before planting. Incorporate it into the soil using a shovel or tiller.
2. Fish Emulsion and Bone Meal: Fish emulsion is typically applied as a foliar spray or soil drench. Bone meal should be mixed into the soil before planting to provide slow-release nutrients.
3. Green Manure: Grow green manure crops during the off-season and till them back into the soil before planting your main crops.
