Several states around the country compile custom application rates for field work, but a project that would seem to be something easily coordinated for gathering the same information with the same questions isn’t happening.

What should be easy examples for comparison are fertilizer application and chemical application for control of weeds, insects and fungicides. But there isn’t consistency in the description of operations in the final analysis of information gathered from the groups of farmers surveyed and responding.

With a little interpretation, some basic costs can be pulled from different states’ farmer surveys, which show some comparisons by regions. Below are the average cost of custom application services charged farmers in Iowa, Kansas and Ohio, which reflects prices paid for the 2012 crop season:
