Iowa State University's Crop Adviser Institute has developed two educational modules covering research design and data collection for crop production research, designed for newcomers to on-farm research as well as Extension specialists, crop advisors, agribusinesses and growers.
Each course costs $5 and can be viewed online, downloaded to a personal computer or mailed on CD by request. Certified crop advisors (CCAs) who pay $15 per credit for the test, will receive the study material at no cost. Taking both module tests, a CCA can receive up to 5.5 crop management credits.
