ABSTRACT

Site-specific agriculture typically involves dividing a single field into smaller management zones based on variations in soil type and other management factors. Equipment to vary inputs such as fertilizers and insecticides are becoming commercially available; however, systems for site-specific application of irrigation water are still lacking. Additionally, knowing how to adjust water applications within the field would be a challenge even if a variable rate irrigation system were used. This poster addresses both issues. First, a variable rate pivot has been developed and tested on six systems in Georgia. Next, an affordable, wireless soil moisture sensor array was developed that could automatically control the amount of water delivered to different sections of the field. Combined, these two systems have the potential prevent yield loss and reduce water usage.
