Abstract: Historical increases in grain yields have been associated with an undermining of soil organic matter (SOM) and a reduction of nutrient cycling capacity. Nutrient limitations for grain crop production are ubiquitous, and while yield and economic response to fertilization has been exhaustively evaluated on several crops across different environments, the focus has been mainly on individual crops rather than on the cropping system. Benefits of increased fertilization beyond a single cropping season need to be assessed to help preventing the current soil nutrient mining process in the Argentine Pampas.
