SnapPlus crop choices are based on a crop year that generally runs from the day after the fall harvest to the next fall’s harvest, with some variation for crops that do not fit this schedule (for example, winter wheat harvested before fall). When two crops are planted or harvested in a single crop year, these crops are treated as “double crops” in SnapPlus. Both crops in a double crop system appear in the crop name. Examples of a double crop are: winter wheat followed by a late-summer seeding of alfalfa or red clover; canning peas followed by snap beans; and a first cutting of alfalfa hay followed by soybeans. Some crops are followed by “cover crops”. In SnapPlus, a cover crop is defined as not being harvested so the nutrients it contains are not removed from the field. If a small grain grown for winter cover will also be harvested for forage in the following spring, then select the appropriate double crop, such as “Winter rye (forage) to corn for grain” for the next crop year.
