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). Many no-till systems use cover crops of winter annual plants to con serve soil and water and increase nutri-ent recycling (Hoyt and Hargrove, 1986). Cover crop residues usually

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.

Our main objectives were to: 1) evaluate land use ef fects on soil chemical, physical, and biological properties in taxo nomically identical soils to assess soil quality, and 2) define ranges in near-surface soil properties impacted by variation in soil management strategies.
Four Strategies to Improve Your Field s Soil Health
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.

Total SOM or SOC are standard soil tests, but they are not always representative of the active soil C fraction that contributes to nutrient cycling, soil structural stability as well as overall soil health.

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. Legume species, such as crimson clover, are also used as cover crops for their ability to convert inert nitrogen gas into
