A rye cover crop after corn increased SOC relative to the control in the soybean phase, but decreased soil carbon relative to the control in the corn phase.

Principles of Cover Cropping for Arid and Semi-arid Farming

Adding Soil Organic Matter Soil organic matter is very important for the overall health of any agricultural soil. When incorporated back into the soil, cover crops help to increase the soil organic matter, improving the soil s biological activity, moisture retention, nutrient holding capacity, moisture infiltra-tion, and tilth.

soil moisture regimes, excessive soil water in no-till systems can limit crop growth and nutrient utilization (Griffith and Mannering, 1985; Triplett and Van Doren, 1985).

More organic no-till challenges Heavy cover crop residues can interfere with seed-soil contact, resulting in poor cash crop stands. No till with heavy cover crop residues can slow soil warming and delay release of available N to cash crop. As a result, organic rotational no-till systems often give reduced yields.

the residue, nutrients are released back into the soil. Organic matter, a key soil health component, can increase over a longer period as residue is added back into the system. Combining no-till and cover crops is a great way to keep your soil covered, minimize disturbance, maximize living root growth, and maximize plant diversity.

The cover crop helps to keep the soil cool during the hot summer months. Root tunnels formed from the cover crop allow row crops to extend their roots deeper into the soil, adding organic matter and nutrients to the soil.
