Fertilizers condition the soil and build plant hardiness and resistance to drought, pests and disease. They also encourage root growth in seedlings and transplants and promote large blooms and fruits. Organic fertilizers perform these tasks without adding harmful toxins to the environment.
Natural and organic fertilizers differ from chemical fertilizers in that they build the soil as they feed your plants. Soils with an abundance of organic material remain loose and airy, enabling them to retain greater moisture and nutrients.
Fertilizing organically provides a carbon source for the soil. According to branch manager Rick Geise of Nature Safe Manufacturers, this is the key food for soil microorganisms. "By creating an available carbon source for the soil, the microorganism populations increase, transpiring a fertilizer factory effect." ( Irrigation and Green Magazine, June 2000). .
Organic fertilizers have three main compounds for promoting healthy plant growth. Nitrogen, Phosphorous, and Potash (N-P-K) work together to create a product that is nutritious for plants and safe for the environment.
Organic fertilizers are made from a huge variety of naturally occurring elements. Bat guano, bone meal and fish meal are some of the most common material used in the mix.
Adding organic compost to the soil prior to using organic fertilizers is one of the best ways to improve the health of your plants. Compost may help reduce the amount of fertilizer treatments needed. It will also add nutrients to the soil, improve soil drainage and strengthen your plants' immune systems.
Testing garden soil with an electronic soil tester can help determine the quality of the soil. With this knowledge you can decide the best fertilizer to meet your plants' needs.
