Irrigation Webinar Series

Irrigation is expanding to non-traditional areas, primarily to maintain yields and provide insurance against in-season water deficits. In many traditionally-irrigated areas, water of sufficient quantity and quality for irrigation is becoming more limited due to drought, declining aquifers, and competition for surface waters. This webinar series will address four topics that are paramount in improving irrigation water use efficiency: soil moisture monitoring methods, evapotranspiration and crop water use estimation methods, irrigation scheduling (when and how much), and efficiency of the most common irrigation methods.

Irrigation: Managing [Soil] Water and Drought

Managing irrigation begins with understanding the soil as a reservoir for storing plant available water. Plant use is a withdrawal and deposits are made through capture and infiltration of precipitation, and irrigation. Soil profile characteristics and plant rooting depth determine the volume of the soil in which the soil water should be managed. The environmental consequences of mismanaging irrigation and the effects of drought on the soil water bank will be addressed.

Soil Moisture Monitoring Methods: Strengths and Limitations

Many methods of monitoring soil water are available, and the technology ranges from extremely simple to highly technical. This webinar will provide an overview of the operating principles, strengths, weaknesses, and best uses of physical methods and of sensing methods, including the resistance techniques, tensiometry, time domain reflectometry and frequency domain (capacitance) sensing systems. These tools may assist the CCA to help producers use water more efficiently and with fewer environmental consequences.

Irrigation Scheduling Methods: Agronomic, Perennial and Vegetable Crops

In order to effectively manage plant available water in the soil, the CCA needs to consider the water balance – the sum of the inputs and outputs of water into the soil bank. Evapotranspiration is a chief component in the soil water balance, and can be used like an accounting tool to identify when irrigation is necessary and how much water to apply. The most common ET estimation methods will be discussed, and how they can be used for irrigation scheduling. Plant canopy temperature is an indication of plant water stress, and infrared thermometry (IRT) may be used to identify when plants reach a stress threshold temperature at which irrigation should be initiated.

Crop Water Productivity and Irrigation Management

Modern irrigation systems offer large increases in crop water productivity compared with rainfed or gravity irrigation, but require different management approaches to achieve this. Flood, sprinkler, LEPA, and subsurface drip irrigation methods vary widely in water application efficiency, from about 60 to 95% of the applied water that reaches and remains in the plant root zone. This webinar will acquaint CCAs with the principles, components and efficiencies of the most common irrigation technologies, and the advantages, disadvantages and best uses of each. Further, the webinar will address how irrigation may be managed to adjust for decreasing pumping rates and changes in water quality.
