Soil fertility, fertilizers, and crop nutrition: Past, present, and future

Society has made (and will be making) significant demands on agriculture in the not-to-distant future. Meeting future sustainability goals and environmental regulations while simultaneously continuing to meet requirements for food, feed, fuel, and fiber requires a firm understanding of how “we” have collectively arrived at our current status as it relates to our fertility principles and beliefs as well as the processes that address them. We have advanced far from the earliest thoughts on rudimentary plant nutrition to a sophisticated science of prescription crop nutrition. This series intends to describe crop nutrition and fertilizers from where we have been to where the authors believe that we will likely need to be prepared to go if we are to support world demands into the foreseeable future.
