Irrigation

irrigation-research-field

With more than 125,000 acres of irrigated farmland (25% of total farmed acres) in Delaware, irrigation is an essential part of our agricultural economy.

Shared knowledge makes a difference

Farmers are continually looking for new technologies to improve irrigation efficiency, minimize adverse environmental effects and maximize yields. Too much irrigation can adversely influence crop yields, leach nutrients and waste water, while too little can reduce yields, concentrate nutrients in the soil and affect watershed quality.

At the Carvel Research and Education Center in Georgetown and the Warrington Irrigation Research Farm in Harbeson, extension professionals, scientists, engineers and researchers continue to look for ways to improve irrigation efficiency and respond to the need for expanded irrigation resources. 

This shared knowledge allows farmers to learn their local soil characteristics and the most effective way for crops to utilize the applied water and improve nutrient use efficiencies. Cooperative Extension also offers growers site instruction on system calibration, irrigation scheduling, in-depth reviews of high-tech moisture sensor equipment and testing of advanced irrigation techniques.

Sensors: The Good and Bad (2019)

Sensor technologies can improve management through more accurate and timely assessment of crop status, soil water status, and many other facets of agronomic production. Explosive advancements in technology and network connectivity in recent years have made the use of extensive and highly advanced sensor systems possible. This session will focus on which sensor strategies are most appropriate for various types of plant, soil, and water measurement, on new and innovative sensor systems, and on the challenges of data management.

Costs and Benefits of Irrigation in Field Crops (2017)

The capital costs to install irrigation are highly variable depending on irrigation type, field size, water source and geography. This session will weigh the initial setup and operation costs versus the potential yield increases. Application efficiency, pumping costs, management time and maintenance will be quantified followed by a detailed discussion of the qualitative benefits/costs.

Practical Experiences in Farm Drainage Design and Installation (2019)

From spinner ditches and swales to land forming and pattern tiling, the options to improve agricultural drainage can be overwhelming and costly. Many factors come into play when determining the best method to solve complex drainage issues with minimal environmental impact. Modern precision ag systems provide valuable information for drainage planning without the additional expense associated with elevation surveys. This session will discuss the practical side of drainage design and installation and how to take advantage of modern technology and existing data.
