Sprinkler Spacing Student Workbook

A key step in the design of any sprinkler system is deciding where to place the sprinklers. This requires understanding the underlying objective behind all sprinkler spacing decisions: providing a uniform application of water. Uniformity of application relates to sprinkler spacing through the concept of overlap. Learn which factors to consider and how to lay out a sprinkler system for the best results.

Sustainable Irrigation: An Integrated Approach

With the changing elements of agriculture and a growing population to feed, mechanized irrigation for water use efficiency and sustainability is becoming more important for global food production and grower economics. Many tools are available to determine soil, crop and environmental conditions, generating large amounts of data. A grower can be overwhelmed with how to manage this data, how to apply it to their situation, and the necessary tools to truly improve their water use efficiency and help insure sustainability. Mechanized irrigation has long been challenged by the industry to provide an integrated and strategic approach, combining rich available data with advanced mechanized control technology.

Testing Ag Performance Solutions in the Oklahoma Panhandle

The testing ag performance solutions (TAPS) project involves producers in research by applying their management decisions to replicated plots of irrigated corn. It allows producers to select the corn hybrid, population, pre-plant N rate, fertigation rates of N and irrigation water application. Commercial decision support tools such as soil moisture probes, plant growth sensors and aerial imagery are provided to participants to aid in their decision-making. This provides an opportunity for service providers to demonstrate their products in an interactive demonstration. The goal of the project is to maximize efficiency and profitability, instead of simply maximizing yield.

The Hidden Issues of Using Nonpotable Water Sources

Nonpotable water not only includes reclaimed or treated water but also stormwater, water from lakes and ponds, and even some wells because it is not suitable for drinking. In many parts of the country, state regulations require that the source for irrigation water be the lowest quality available to the site because of the increasing demands on the potable water supply. The use of these nonpotable sources comes with an increased number of complications that can be detrimental to the performance of the irrigation system if not identified. This webinar will help landscape and irrigation contractors recognize and deal with these potential obstacles.

TPNRD Water Data Program

The Twin Platte Natural Resources District manages groundwater resources in an area around North Platte, Nebraska. A collaborative effort that was irrigator initiated is changing the landscape of how to gather water data for use in more accurate groundwater assessment and management. TPRND partnered with GiSC, a grower-owned data cooperative, to build the TPNRD-Water Data Program based around smart water meters at every irrigation well. It is a large-scale collaborative effort with TPNRD, GiSC, electric providers in the district, Olsson Civil Engineering, Paige Wireless and irrigators to make this happen. It is an opportunity for irrigators to tell their story and for TPNRD to gather the most extensive set of real-time pumping data ever accumulated utilizing IoT devices.

Use of Satellite Imagery to Calibrate Crop Coefficient

Crop coefficients (Kc) are widely used for predicting crop evapotranspiration for irrigation management; however, the spatial and temporal variation of Kc for different crops can significantly affect ET estimation. Using satellite imagery to calibrate Kc has the potential to solve the issue due to cloud-based technologies and high-resolution satellite imagery being more cost-effective.

Using the Indicator Plant Method to Calculate Drip Emitter Requirements

The typical landscape bed is designed with plants having different irrigation water requirements, yet they are all on one irrigation zone. This webinar will use the indicator plant method of selecting the flow and quantity of emitters per plant-water-use type to apply the required amount of water for each plant. This method can also be used for line source drip and even mixing different types of overhead irrigation. (Don’t tell the irrigation police!)

Water Conservation Approaches in Turfgrass Systems

Two different approaches of water conservation will be discussed during this webinar, based on information obtained from two separate research projects at Kansas State University. Project 1: Subsurface drip irrigation is increasingly popular because of its potential for conserving and uniformly distributing water. We investigated the effects of straw and poly-mesh germination blankets in combination with SSDI on germination and establishment of tall fescue turfgrass. Under ground covers, soil temperatures were 5-7 degrees higher and erosion during rainfall was reduced, resulting in uniform and faster germination of tall fescue compared with no ground covers. Project 2: Irrigation strategies typically rely on calendar or evapotranspiration schedules that completely ignore soil moisture. Our research approach is to integrate the components of the soil-plant-atmosphere continuum by utilizing sensor-based technology to determine turf canopy responses to soil water deficits and to improve irrigation decisions. Water savings of 70% have been achieved using this approach.
