The Earth loses roughly 23 billion tons of fertile soil every year. At this rate, all fertile soil will be gone within 150 years, unless farmers convert to practices that restore and build soil organic matter, an essential component of soil fertility.
Many industrial agricultural practices are lethal to soil fertility, including deforestation and burning, and excessive use of synthetic fertilizers and other toxic chemicals. One of the biggest contributors to soil degradation is the common practice of soil tilling. Fortunately, a growing number of farmers realize the importance of preserving and improving their soil by adopting no-till practices.
