Managing soil fertility is challenging because it requires considerable focus—you must consistently pay attention to the source, timing, rate, and placement of nutrient applications. This publication discusses the many types of fertilizers and soil amendments (material or techniques that improves a soil’s physical properties) available for organic plant production. From soil fundamentals (pH, testing) to fertilizer recommendations (nutrient ratios) to soil amendment options (cover crops, mulches, etc.) to working with organic fertilizers, you’ll get the information and strategies you need to help master the maintenance of healthy soil in your organic garden.

Authors: Doug Collins, Carol Miles, Craig Cogger, and Rich Koenig
