Why does crop rotation keep farmland more productive?
May 13, 2012 6:59PM
Certain crops such as corn can deplete more nutrients from the soil than others. This can leave the soil stripped and barren of key nutrients if planted with such plants repeatedly. Some plants are also nitrogen fixers, meaning they put nitrogen into the soil. Nitrogen is a great nutrient and thus planting those crops in different areas helps to replenish the nitrogen in other areas. Crop rotation is also vital because each variety of any given plant will give back certain nutrients at the end of the growing season after it dies and decomposes. Rotating your crops is a good idea for these reasons and for sustainable farming. Hope this helps, I come from many generations of farmers.
