Existing Problem: Reduced Angle Impact Sprinklers on Top of Boom

Low angle, less than 23 degree sprinklers, typically operate in a pressure range of 20 to 50 psi. Using larger droplet sizes and less distance to reach the soil, they are more efficient than high angle, high pressure sprinklers found on many older systems. But further improvements can be obtained with the lower pressure, larger droplet sizes, closer to the ground or more compact spray patterns afforded by other sprinkler packages. As always, soil intake rate, total pivot boom length, and, in some cases, cropping system will determine which if any replacement will improve application efficiency.
