Fred Abels implements strip-till practices on his 380-acre farm as well as cover crops, a saturated buffer, filter strips, Conservation Reserve Program (CRP) land, pollinator habitat, nutrient management, a windbreak and a new wetland designed to improve water quality and wildlife habitat.
The Hutchisons' use of variable-rate nitrogen applications onto crops are split up through the growing season to boost yields while reducing the potential for runoff. To further protect water quality, they practice mulch and strip-till practices, have installed grassed waterways and buffers, and have completed wetland restoration projects and forest management.
During the last fiscal year, which ended on June 30, state cost-share leveraged $56.42 million in practice implementation, an increase of nearly $3.8 million over the previous record year.
"The reason we have not been able to seriously address water quality is because we primarily focus our efforts on treating the symptoms of poor water quality rather than addressing the underlying cause of the problem," Brian Dougherty says.
Cover crops reduce sediment loss and total phosphorus loss from no-till corn and soybean fields, according to a study published in the Journal of Environmental Management.
"One concern I have is that some growers treat their P and K like balancing a checkbook, trying to calculate what is taken off the field and putting that amount back on in fertilizer. In almost all cases, this type of accuracy is not needed for removal-based guidelines," says nutrient management specialist Dan Kaiser.

This memo reaffirms EPA's commitment to working with others, including the agriculture community, to advance progress in reducing excess nutrients in the nation's waters.
