Carroll, OH | The standing straw will not provide weed control. Planting green is so the root exudates from the rye suppress small seeded weeds from germinating (allelopathy) and the shade and competition keep everything else in check. Live plants respire soil moisture which is important for us in the Midwest with wet spring weather, and the roller down cover crop mat shades the soil to again keep weeds from germinating, keep soils from getting too hot in the summer, and build soil organic matter as well as provide habitat for beneficial insects.
In your scenario we would recommend seeding some legume like clover or a bean like cow pea or mung bean into the stubble to add some Nitrogen and aid in residue decomposition. | |
