Cover Crops
                           

Cover crops are grasses, legumes, forbs, or other herbaceous plants established for seasonal cover and other conservation purposes.  Cover crops protect the soil from erosion during the most vulnerable time of the year from harvest in the fall to the formation of the plant canopy in summer.

                                                                                        

Cover crops can reduce fertilizer and pesticide costs.  Cover crops capture nitrogen and release it as the cover crop decays.  Legume cover crops capture nitrogen from the air.  Reduced soil loss retains phosphorus attached to the soil.  Proper timing of cover crops suppresses weeds and breaks disease cycles. 

Cover crops can provide supplemental forage for grazing or harvesting.  Winter rye seeded after corn silage or soybeans are harvested can be grazed the following spring.  This allows more time for forage in permanent pastures to become better established before grazing them.  Rye that is aerial seeded in August can sometimes even be grazed in the late fall.  Alfalfa planted after harvesting canning crops can still be harvested once by the end of the season.  Alfalfa seeded later established better and those acres are also available for applying manure.
