Drought-decimated Corn Crop Creates Ideal Situation for Employment of Cover Crops, Says Purdue U. AgronomistSeptember 20, 2012 | Purdue University
News Release – WEST LAFAYETTE, Ind. – Drought-decimated corn crops are likely to leave residual nitrate in soils after harvest, making this year ideal for farmers to plant cover crops, says a Purdue Extension agronomist.
Cover crops can “scavenge” residual nitrate and recycle it through biomass. The process helps reduce nutrient loss through leaching and runoff, and makes some of those nutrients available for the next cash crop.
