Using Cover Crops

[Jayson]

Some farmers plant a big load of cover crops, crops not harvested but only used to preserve nutrients, during the off-season.  OK, who has done this and what crops do you recommend?  

Anyway, some benefits of cover crops are the following:

• soil quality improvement
  
• a bulwark against erosion
  
• improved fertility
  
• insect prevention
  
• weed prevention
  

OK, the crops that I read are good cover crops are:

• oats
  
• soybeans
  
• clovers
  
• rye
  
• alfalfa
