Evaluation of variable rate irrigation using a remote-sensing-based model
Improvements in soil water balance modeling can be beneficial for optimizing irrigation management to account for spatial variability in soil properties and evapotranspiration (ET). A remote-sensing-based ET and water balance model was tested for irrigation management in an experiment at two University of Nebraska-Lincoln research sites located near Mead and Brule, Nebraska. Both fields include...
متن کاملIrrigation Scheduling Using Remote Sensing Data Assimilation Approach
Remote sensing and crop growth models have enhanced our ability to understand soil water balance in irrigated agriculture. However, limited efforts have been made to adopt data assimilation methodologies in these linked models that use stochastic parameter estimation with genetic algorithm (GA) to improve irrigation scheduling. In this study, an innovative irrigation scheduling technique, based...
متن کاملPerformanance Evaluation of the Cauvery Irrigation System, India, Using Remote Sensing and Gis Technology
Evaluation of any irrigation project involves the assessment of area, improved by the project. Irrigated agriculture will play a major role in determining the future food security of most Asian countries, and it will also be the major contributor to the additional food production required as world population expands. Therefore, it is important to raise the agricultural performance of low produc...
متن کاملEvaluation of Dust Effects on Spectral Behavior of Plants Using Remote Sensing Data
Introduction Dust is one of the important climatic phenomena that has occurred in arid and semi-arid regions of the world. In recent years, one of the most important environmental issues in the Middle East and Iran is the occurrence of dust phenomena that affects a variety of factors, including human health, plants and other living organisms, economic conditions, and etc. One of the effective ...
