Iowa Soybean Association environmental scientist Chris Jones says he’s seeing increased interest in cover crops this fall as a way of holding nitrogen in the soil following the very dry 2012 growing season.
Jones says the lower yields caused by the drought mean more N is being left in the fields. Jones says a cover crop, such as rye, oats or radishes, planted this fall can help sequester–or tie up—that nitrogen that would otherwise be lost.
