Organic Fertilizers and Soil Amendments

Organic fertilizers are derived from animals, vegetables and minerals. A living soil, rich in humus, beneficial microbes and nutrients, is the base for organic gardening. Many organic materials serve as both fertilizers and soil conditioners—they feed both soils and plants. The fertility and viability of the soil is the foundation of organic gardening.

Using Organic Fertilizers

Organic fertilizer blends can be just as convenient and effective as blended synthetic fertilizers. Specialty organic fertilizers pre-mixes, such the ones by FoxFarm and Happy Frog offer an optimal nutrient solution for different plant types and life cycle stages. Another approach to organic gardening is to make a custom blend of individual organic components to address the plants’ specific needs. For example, mix bat and bird guano, blood meal, or fish meal as nitrogen sources. Flowering guano, bonemeal and rock phosphate are a good source of phosphorus, and kelp, langbeinite and greensand are organic sources of potassium.


Dry Organic Fertilizers

Dry organic fertilizers can consist of a single material, such as rock phosphate or kelp (a type of nutrient-rich seaweed), or they can be a blend of many ingredients. Almost all organic fertilizers provide a broad array of nutrients, but blends are specially formulated to provide balanced amounts of nitrogen, potassium, and phosphorus, as well as micronutrients. There are several commercial blends, but you can make your own general-purpose fertilizer by mixing individual amendments.

Liquid Organic Fertilizers

Use liquid fertilizers to give your plants an instant nutrient boost. Plants can absorb liquid fertilizers through both their roots and through leaf pores. Foliar feeding can supply nutrients when they are lacking or unavailable in the soil, or when roots are stressed. It is especially effective for giving fast-growing plants like vegetables an extra boost during the growing season. Some foliar fertilizers, such as liquid seaweed (kelp), are rich in micronutrients and growth hormones. These foliar sprays also appear to act as catalysts, increasing nutrient uptake by plants. Compost tea and seaweed extract are two common examples of organic foliar fertilizers.


Organic Growth Enhancers

Growth enhancers are materials that help plants absorb nutrients more effectively from the soil. The most common growth enhancer is kelp (a type of seaweed), which has been used by farmers for centuries.
