Resource Conservation
Resource conservation means that those resources on which sustainability depends are conserved and even enhanced by agronomic management. Soil organic matter is a good example of an ecosystem resource that is easily reduced without effective management. Soil organic matter declines rapidly in almost all cropping systems following initial cultivation – typically to 40–60% of original values within a few decades. However, soil organic matter is a valuable resource, providing habitat and energy for soil organisms, a soil structure favorable for plant growth and water retention, and a chemical structure favorable for nutrient retention (Robertson and Grandy, 2006).
