Impacts of Cover Crops and Tillage Systems on Phosphorus Loss from Corn and Soybean Fields Wednesday, June 9 (12 pm - 1 pm)
Research has demonstrated that no-tillage and cover crops are very effective conservation practices to reduce soil erosion and sediment-bound phosphorus (P) loss from agricultural fields. However, research in other states has shown that these practices may not reduce and may even increase loss of dissolved P with surface runoff compared with tillage or no use of cover crops.
Although dissolved P is often a minor proportion of the total P in runoff when compared to the sediment-bound P fraction, it is the most effective P fraction at causing water quality impairment. Antonio Mallarino, professor and extension specialist in the Department of Agronomy at Iowa State University, will share Iowa field research results that evaluated the effects of these management practices on soil, total P, and dissolved P with surface runoff.
