Precision Agriculture for Sustainability. Cambridge, UK: Burleigh Dodds Science Publishing. p. 115-125. Interpretive Summary: Site-specific nutrient management systems were created to manage for spatial and temporal variability in biophysical factors that determine the availability and demand of crop nutrients. These systems differ among geographical regions in the information utilized and way they operate to accomplish their common purpose: namely, improve nutrient use efficiency and balance tradeoffs between profitability and environmental concerns. This chapter looks at system inputs that are used to inform site-specific nutrient management, illustrates system processes and outputs with examples from the Midwestern and Western United States, and identifies trends and further developmental needs.
