FYI: Organic Fertilizers

One aspect of farming organically is applying organic fertilizers to the soil throughout the season. While more expensive than synthetic fertilizers, organic fertilizers are well worth the cost. There are many problems with synthetic fertilizers. Excess nutrients (nitrites) pollute our waters destroying fragile ecosystems and harming drinking water. Synthetic fertilizers deplete soil of nutrients and organic matter whereas organic fertilizer and crop rotation help to enrich the soil. All fertilizers provide nutrients to plants to foster growth. Macronutrients in fertilizers include nitrogen, phosphorous and potassium (N-P-K) and important micronutrients such as iron and copper. Examples of naturally occurring organic fertilizers include greensand, which is a natural potash, manure, peat, and worm castings (or worm compost). "Manufactured organic" fertilizers include compost made from vegetation and fish emulsion fertilizers. Enhancing soil health is the cornerstone of organic gardening and organic fertilizers. Healthy soil equals healthy food and healthy people (and a healthy planet).
