In-Depth Information
To get there, however, we are going to have to understand better the biological and
ecological processes regulating N cycling in agricultural systems; we also need to advance
our understanding of how soil communities and processes respond to differences in
edaphic soil properties, climatic conditions, and management. With the widespread appli-
cation of molecular methods to soils, we are beginning to fully characterize and quantify
the diversity of soil microbes. We are also beginning to gain insights into the factors driv-
ing the distribution of microorganisms across soils, link patterns in soil diversity to soil
functions through targeting functional genes and metabolic pathways, and understand
the broader-scale ecological relevance of soil biological processes occurring at very small
scales. These are promising advances, and as our knowledge of soil biogeochemical pro-
cesses moves forward, we need to look for every opportunity to apply emerging scientific
concepts to managing N in agroecosystems.
