UI Extension Drought Resources

Idaho’s vast Snake River plain is one of the most productive irrigated agricultural regions in the western United States. Without vital irrigation water, farm and ranch producers are unable to provide the crop and livestock resources essential for the economy of Idaho. Without irrigation, the high desert of southern Idaho would revert back the rangeland it was prior to irrigation development in the early 1900’s.

Howard Neibling (UI) and Troy Peters (WSU) are currently working on a joint research project to adapt this irrigation scheduler to Idaho crops and conditions.  It was initially developed at the Washington State University (WSU) Irrigated Agriculture Research and Extension Center (IAREC) in Prosser, Washington by Sean Hill and Cynthia Tiwana under the direction of Troy Peters, Extension Irrigation Specialist and Assistant Professor at Washington State University.  It uses grower-specified crop and soil characteristics and downloads information from the specified AgriMet station to estimate root zone soil moisture and the amount of irrigation required to re-fill the root zone on a daily basis.
