Farmers and ranchers use the term soil health to describe the condition of the soil. Scientists usually use the term soil quality, but both refer to the same idea — how good is the soil in its role of supporting the growth of high-yielding, high-quality, and healthy crops? Healthy soil generates higher crop yields, it absorbs and holds rainfall, and erosion is therefore reduced. The information here will show you how to improve soil fertility and build healthy soil. Two comprehensive books to consult are Building Soils for Better Crops and Managing Cover Crops Profitably.
Crop rotation, the use of diverse soil management practices, composting, and cover crops all contribute to healthy soil by conserving and building soil organic matter, absorbing rainfall, and retaining crop residues on the soil surface. Major conservation practices include conservation tillage, contour farming, strip cropping, terraces, diversions, and grassed waterways.
Soil consists of four parts: mineral solids, water, air, and soil organic matter. All four are important characteristics of fertile soil.
