Soil microbiology, ecology, and biochemistry

Our science, based on a successful past, has great potential for an exciting, dynamic future if we understand it and apply its unifying principles. Advances in genomic studies are identifying multitudes of new soil biota. Automated, analytical instrumentation and modeling are characterizing soil organic matter and its dynamics. Soil nutrient transformations, plant–microbial interactions, substrate availability, and interactions with the soil matrix at the nanometer and micrometer levels must be understood. They also need to be interpreted to kilometer–megameter scales required for both global C and N cycling as well as an increased understanding of human resources. The turnover of soil organic matter, now considered to be primarily microbial products, controls nutrients such as phosphorus, sulfur, and metals. Our complex field requires a greater knowledge of physiological, ecological, and modeling concepts. These concepts must be integrated with information on soil characteristics and breakthroughs in methodology to understand the diversity, occurrence, and interactions of organisms with their environment.
