Ec89-723 Irrigation Scheduling Using Soil Moisture Blocks In Silty Soils, William L. Kranz, Dean E. Eisenhauer

University of Nebraska-Lincoln Extension: Historical Materials

Irrigation takes some risk out of crop production by providing a reliable source of water that allows the producer to manage soil water. Monitoring soil water is fundamental to determining how much irrigation water should be applied, and when the soil is able to store the amount of water to be applied.

This publication describes how to use soil mositure blocks to schedule irrigations in fine textured soils.

G89-932 Minimum Center Pivot Design Capacities In Nebraska, William L. Kranz, Derrel L. Martin, Greg Lackas

University of Nebraska-Lincoln Extension: Historical Materials

Factors to consider in choosing an appropriate center pivot design are covered here. Irrigators investing in a center pivot irrigation system need to consider this important question: How much supplemental water is required by the crop? Irrigation system capacity needed to meet crop requirements is defined in units of gallons per minute (GPM) or gallons per minute per acre (GPM/AC). If the system capacity is too low, crop stress occurs during some portion of the growing season. If the capacity is too high, surface runoff may result, or capital investment for the pumping plant and center pivot may be greater …
