Vol. 35, No. 3, pp. 20-21. Interpretive Summary: Prediction of optimum nitrogen for hay and forage crops is difficult due to lack of tests for soil nitrogen availability. A scientist with the USDA Agricultural Research Service in Raleigh North Carolina summarized a soil testing approach for predicting nitrogen availability from soil biological activity. This approach was described for farmers to better understand how their management of soil health condition might influence yield responses to nitrogen fertilizer inputs. Soil-test biological activity provides a good way to estimate the supply of nitrogen from soil organic matter, allowing farmers to focus on how much inorganic nitrogen fertilizer to get the most economical yield responses without causing nitrogen loss to the environment.
