A study found that legume covers actually supplied little total nitrogen due to low biomass production, while the nitrogen contained in cereal rye residue was likely readily available for the next corn crop.
The Iowa State University Horticulture Research Station assessed five cereal rye cultivars for their anthesis timing, biomass production and carbon-to-nitrogen ratios.
Continuous no-till can go a long way toward keeping soil where it’s supposed to be, but a monster rainstorm falling on soybean residue can still result in ephemeral gullies.
Trap crops are used to absorb nitrogen from the no-till soil. If the cover crop is not grazed or harvested, the N taken up by the crop remains on-site and is preserved within the residue for use by future crops.
