Ground-based remote sensing of corn evapotranspiration under limited irrigation practices
Irrigated agriculture is the largest user of fresh water resources in arid/semi-arid parts of the world, where water is highly-demanded and usually over-allocated. Therefore, it is of crucial importance to accurately identify irrigation requirement of agricultural crops, known as evapotranspiration (ET). In this study, ground-based remotely sensed data were used in two major approaches to estimate crop coefficient (Kc) and ET over two treatments of limited-irrigation corn in northeastern Colorado. The first approach was the reflectance-based Kc, while the second approach was more complex and ...
