High soil organic matter and
good soil structure resulted in excel-
lent yields. With a yield map, a producer can compare the yields between highly productive and less productive areas
and make appropriate management decisions and answer questions such as: Is intervention a good investment?
Figure 2 presents profit maps created from the yield map shown in Figure 1. The profit maps were created by multiplying
the yield data by the market price of cotton lint and then subtracting the production costs. The result is a map of net revenue
in terms of dollar per acre commonly referred to as a profit map. The profit map on the left uses the 2011 Georgia estimates
for the price of lint and irrigated production costs – $1.00/lb and $528/ac, respectively
