The cost-benefit analysis of 43 fields of cotton defoliated using at least one pass with variable rate chemical application, showed significant benefits for the farmers involved. The average savings in chemicals when compared to what would otherwise have been applied was $11.82/ha. The farmer was able to save, on average, 25% of his chemical bill. In most situations this savings in chemicals more than covered the cost of the Belt-Wide Agriculture service ($10/ha) and left around $4.23/ha in the farmers pocket.
