New-to-Canada cover crop salvages nutrients, improves water and air movement in soil, protects from pests and increases crop yields. Very aggressive when rooting, tillage radishes can exert 290 pounds per square inch of pressure as they drill down, which allows them to punch their way through compacted soil and hardpan. Cover crops are not yet grown much in Canadian fields. However, tillage radish, a fast-growing, all-natural cover crop, may just change that. According to Patrick Fabian, tillage radishes do everything from increasing nutrient availability for subsequent crops, to suppressing pests and supporting healthy soil organisms, to improving water and air movement through soil. That, combined with the fact that studies now show yield increases of up to 10 and 11 percent respectively in soybeans and corn planted into decomposing tillage radishes, means this cover crop is making significant waves south of the border.
