Note: To control the cover crop, the roller-crimper needs to snap the cover crop stem rather than simply bend them. Comparing crop emergence and weed suppression among species was a top priority, as weed control is one of the main concerns for organic farmers. There were also six demonstrations plots planted without replication, including Austrian winter pea, cereal rye/pea mix, and mustard/radish mixtures. Some species grow better than others in low fertility and/or poorly drained soils. Increase Soil Fertility. Farmers use cover crops to improve soil, avoid erosion and keep weeds at bay, but there was no formal way to corral the available information for the growers who need it.

Plant Guide for Oilseed Radish (Raphanus sativus) (PDF; 225 KB) Oilseed radish is a cultivated annual/biennial species in the mustard family used as a cover crop on croplands. The cereal rye/pea and mustard/radish mixtures did not produce as much biomass as the single species counterparts (data not shown). Soil in incubation bags was subsampled at 4 and 8 weeks to determine nitrate-N concentration. All four species struggled to be as competitive against weeds as compared to the spring planting date, but phacelia provided the most weed suppression (2.8 weeds/ft2). The Caliente mustard and crimson clover plots became overrun with weeds and were discounted as treatments. But a cover crop, that is properly designed with the right species in the mix, and planted and terminated timely, can mitigate that moisture use by reducing soil water evaporation, improving water infiltration and increasing organic matter. Neuman, Joshua Caleb. Improving soil – Poor soil structure can be improved by selecting cover crops that produce large amounts of biomass.
