Overview
Effective use of crop rotation is known to have a dramatic positive influence on the yields of many crops. MASC consistently sees some crops performing better when planted after others. The tables (below) provide real-life rotation responses that can be used to help with crop choice planning, whether it’s deciding how to sequence your tried-and-true crops or selecting new crops you want to plug into your field cycle.
Additionally, it is well established that the provision of a break interval between similar crop types allows time for the decline in carryover problem biological organisms and problem soil conditions during the interval when unrelated crops are grown. In theory, the longer the break interval is, the greater the reduction in carryover problems, leading to overall improved yields. These tables show and quantify the real-life impact of break intervals of various durations on crop yields.
