I am in the third year of the cycle, therefore the next cycle will be as follows: Plot     Year1 (2011)           Year 2 (2012)       Year 3 (2013)    1         Root Crops              Others             Brassicas   2         Brassicas               Root Crops          Others   3         Others                  Brassicas           Root Crops
