Oklahoma Certified Crop Advisers

Animal agriculture is a large segment of the economy in Oklahoma. The huge quantities of manure generated by animal feeding operations (AFO's) can be an economical source of plant nutrients and a valuable soil amendment to Improve Soil Quality and Maintain Soil pH. Thus, manure can be a valuable asset to a livestock production operation if its nutrients and organic matter are recycled through land application properly.


The Oklahoma CCA program is a voluntary certification program for individuals who provide advice to growers on crop management and inputs.
