The management goal of plant productivity aims to maximize the growth and quality of desired plants. For a farmer the desired plant production might be marketable crops, for a rancher it might be palatable forage, and for a wildlife manager it might be habitat vegetation. The management goal of waste recycling aims to use the soil efficiently as a means to safely and beneficially deal with manure, sewage sludge, or other 'wastes.' The goal of environmental protection aims to detoxify, immobilize, or isolate potential contaminants so as to protect food webs and enhance ( or at least maintain) the quality of soil, water, and air resources. The relationship between these broad management goals and more specific soil functions is illustrated in Figure 20.1. In this context, soil quality describes the capacity of a soil to perform a particular set of functions that are required to meet a given management goal.
