Precision agriculture is the management of an agricultural crop at a spatial scale smaller than the individual field. Mineral nutrient levels, soil texture and chemistry, moisture content and pest patterns may all vary widely from location to locat

Intensive dairy production generates large amounts of manure, which is typically reused as fertilizer for the production of forage. In the Central Valley of California, application of manure often results in high inputs of N and labile organic C, a c

Nitrogen (N) use in intensive agriculture can degrade groundwater resources. However, considerable time lags between groundwater recharge and extraction complicate source attribution and remedial responses. We construct a historic N mass balance of t

Soil tests commonly used to develop potassium (K) fertilizer recommendations, such as extraction by 1 M ammonium acetate (NH4OAc) at pH 7, measure both soluble and exchangeable K. In soils that fix K so that it is no longer exchangeable, although a p

The high-value, large-scale crop production systems in the San Joaquin Valley (SJV) of California typically entail intensive tillage and large fertilizer and water inputs but few C additions to the soil. Such practices often contribute to a decline i
