As a result of such destructive practices, in Europe alone, around 70 percent of the soil is considered unhealthy. The blue arrows represent basic nutrient pathways such as plant uptake, biomass decomposition, and nutrient return to soil. Healthy soil is a dynamic living ecosystem: a complex combination of minerals and organic matter containing air, water, and life. Productive and healthy soil helps farmers meet increased demand for agricultural commodities from a growing global population, driving economic growth. Unauthorized use is prohibited. But our soils are degrading at an alarming rate. These are caused by depletion of underground water sources known as aquifers, a lack of rainfall due to drought, or pollution of water supplies. Replacing our reliance on monoculture with a return to crop rotations gives soil time to replenish the nutrients needed by plants. They protect soil by reducing runoff. Most of us have probably realized it by now; that soil is necessary for the sustainability of humankind. Implementation of agricultural best management practices (BMPs), and through the practice of conservation agriculture, the rate of soil loss can be reduced to approximately equal the rate of soil formation, although often still greater than that in natural systems (Table 2). The UK has a legacy of contamination thatneeds to be addressed.
