Comprehensive agricultural models are crucial for assisting several decision makingprocesses due to their capability for use under different conditions. SALTMED is a holisticgeneric model, which simulates yield, dry matter and soil water content under differentirrigation managements and systems. The aim of this study was to calibrate the SALTMEDmodel to simulate wheat yield, dry matter and soil...

To examine the impact of small reservoir irrigation development in Africa, the performance and productivity of two small reservoirs and irrigation schemes in the Upper East Region of Ghana were investigated in this study. Hydrologic data measured included daily irrigation volumes and daily evaporation. Farmer cost inputs, excluding labor, and harvest data were also recorded. There was a strong ...

Irrigation has become commonplace for residential homeowners desiring high quality landscapes in Florida. The goal of this project was to document irrigation system uniformity in Central Florida and to quantify distribution uniformity of residential sprinkler equipment under controlled conditions. The catch-can testing procedure used was a modified version of both the American Society of Agricu...

This report investigates the costs and benefits associated with the conversion from semi-enclosed seep irrigation to either automated seep or automated sub-drip irrigation for potato production in Northeast Florida. These costs and benefits are estimated at the level of the individual grower and for the public at large. The analytical tools in the report include financial budgeting and regressi...

Water is a limiting factor in agriculture and when improperly managed reduces the yield potential of crops. The objective of this study is to develop a Fuzzy Irrigation Decision Support System (FIDSS) to optimize water management for soybean production. Management of irrigation systems for greatest benefit requires an understanding of many physical, biological and chemical processes, and econom...

Maintaining a good irrigation system is a necessity in today’s water scarcity environment. This paper describes a new approach for automated Smart Irrigation (SIR) system in agricultural management. Using various types of sensors in the crop field area, temperature and moisture value of the soil is monitored. Based on the sensed data, SIR will automatically decide about the necessary action for...

To improve agricultural water resources’ utilization, crop’s automatic, locate, time and appropriate drip irrigation is a good choice. In this paper, an automatic control drip irrigation system based on ZigBee wireless sensor network and fuzzy control would be introduced. System uses CC2430 for wireless sensor network node design, collecting soil moisture, temperature and light intensity inform...

A field crop irrigation management decision-making system (CropIrri) was developed based on the soil water balance model, crop phenology model, root growth model, crop water production function, and irrigation management model. The irrigation plan is made through predicating of soil water content in root zone and daily crop water requirement using historical and forecasting weather data, measur...
