Researchers in agricultural and environmental sciences discuss principles and practices of soil management on large commercial scales. Their topics include balancing productivity and environmental quality in tillage, potassium cycling, gas exchange in soils, increasing the efficiency of water use in field crops under changing climates, subsurface drainage design and management to meet agronomic and environmental goals, crusting, fallow effects on soil, intercropping and its implications for soil management, and soil management implications of producing biofuel feedstock.
