(109) Evaluation of Weather-sensing Landscape Irrigation Controllers

Water Conservation Potential of Landscape Irrigation Smart Controllers

In the past ten years, smart irrigation controllers have been developed by a number of manufacturers and have been promoted by water purveyors in an attempt to reduce excessive irrigation. Legislation has been introduced in California and Texas and passed in Florida mandating or incentivizing the use of these controllers. As a result of the interest in smart controllers, their use is increasing...

Interactions of Nitrogen, Weather, Soil, and Irrigation on Corn Yield

but no difference in yields with increased N when the season was cool. Numerous factors that affect corn yield in the Northern Great Soil moisture status is also important in maintaining Plains are not considered in current N fertilizer recommendations. A maximum corn yields, and maintaining optimal soil moislinear model to describe the interactions of N fertility, weather, soil, ture is facili...

Farm-Level Risk Management Using Irrigation and Weather Derivatives

An agronomic crop growth model—the Decision Support System for Agro-Technology Transfer—and a constant relative risk aversion utility function are used to examine corn irrigation strategies in Mitchell County, Georgia. Precipitation contracts are designed to help farmers manage risk. Three conclusions originate from the findings. First, the optimal irrigation strategy can greatly increase produ...

Risk Management for Arable Farms: Irrigation and Weather Derivatives

With the Water Framework Directive (WFD), the European Union has established a legal framework for the protection of all aquatic ecological systems including groundwater. In this paper the economic impacts of the WFD for irrigated agriculture with regard to the reduction of water withdrawal permits and various scenarios are analyzed. The results show that decreasing water permits cause decreasi...
