You will be able to re-enroll in the CFA recertification programs at https://register.ext.vt.edu/search/publicCourseAdvancedSearch.do?method=doPaginatedSearch&cspIndex=true&showInternal=false&courseSearch.courseDescriptionKeyword=fertilizer; however, there will be a minimal fee for enrollment ($10) and all testing modules will have to be completed again in the new system, regardless if they have been completed in the previous CFA programs.
Fertilizer Applicator Certification Training (FACT) is a cooperative effort of Virginia Cooperative Extension (VCE), Virginia Department of Agriculture and Consumer Services (VDACS), and the Virginia Department of Conservation and Recreation (DCR).

Summary: The goal of irrigation is to add water to the soil where the plant roots are actively growing (the root zone). The soil serves as a water reservoir, from which plants can withdraw water needed for growth. In irrigation management, it is necessary to know the characteristics of the soil in the area that you will be irrigating. These soil characteristics can be used to determine the amount of water in the root zone that is available to the plants.
After completing this lesson, you will be able to:
- Describe the concept of depth of water.
- Determine the depth of water that is available to the plants.
- Use the concept of depth of water to estimate the net irrigation requirement (i.e., soil water deficit) of the soil root zone.
Time Required: We estimate it will take you 2 hours in total to complete the lesson. You can work on it at your own pace and do not have to complete it in one setting.
Who Would Benefit: A variety of people will find this upskilling course useful from adults to high school students. This includes careers (or hobbyists) growing plants (ie field crops, greenhouse production, turf and lawns, gardens, etc.) and wishing to save money and water by better timing irrigation applications.
Upskill Credentials: If you finish the entire course including passing a final quiz (which you can take up to 3 times), then you will earn a badge certificate of completion. It has been approved for 2 Soil and Water Management CEUs through the national Certified Crop Adviser program.
Instructor: Dr. Allan A. Andales is a Professor and Extension Specialist of Irrigation and Water Science in the Department of Soil and Crop Sciences, Colorado State University (CSU). He has a joint appointment in the Department of Civil and Environmental Engineering. Dr. Andales applies principles of soil and water engineering, environmental biophysics, and numerical methods to study the effects of management practices and environmental factors on field hydrology and agricultural production. Experimental data are used to develop computer models and decision support tools that can improve agricultural water use efficiency and water quality. He is a member of the CSU Extension Water Resource Management Team that engages the public in addressing agricultural and urban water issues in Colorado.

Summary: To effectively utilize limited irrigation resources in the most cost-effective manner requires balancing the inputs and outputs of water fluxes, as well as water that is stored in the soil profile. Best irrigation management scheduling practices focus on water balance in the rootzone because that is where the plant/crop is extracting water (and nutrients) from the soil. It is here we estimate the irrigation water requirements to maintain healthy plants. Decisions on when and how much irrigation water to apply depends on the soil water deficit and the management-allowed depletion (MAD). This lesson will walk you through each of these concepts including real world problem scenarios.
After completing this lesson, you will be able to:
- Use the water balance of the root zone to estimate the irrigation water requirement.
- Make irrigation decisions by comparing the soil water deficit to the management-allowed depletion.
Time Required: We estimate it will take you 2 hours in total to complete the lesson. You can work on it at your own pace and do not have to complete it in one setting.
