G85-753 Irrigation Scheduling Using Crop Water Use Data, C. Dean Yonts, Norman L. Klocke

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes using the "checkbook" method to schedule irrigations based on crop water use data.

Irrigation scheduling determines when and how much water to apply to meet crop demand. Soil water status and current crop water use are key factors for scheduling irrigations. Field observations and crop growth stage are important, but scheduled irrigations result in better rainfall use while avoiding crop water stress or excessive irrigation.

G85-750 Terrace Systems For Nebraska, Elbert C. Dickey, Tom Hamer, Delynn Hay, Paul J. Jasa

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes how different terrace shapes and systems can be used to reduce soil erosion losses on sloping fields. Loss of valuable topsoil to erosion prompted Nebraska farmers to build terraces as early as the 1920's. Current estimates indicate that water erodes as much as 140 million tons of soil annually from Nebraska's fields.

G85-762 Soybean Yield Loss Due To Hail Damage, Charles A. Shapiro, T.A. Peterson, A.D. Flowerday

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses the methods used by the hail insurance industry to assess yield loss due to hail damage in soybeans. A hailstorm can cause yield losses in soybeans ranging from slight to total destruction of the crop. Extensive research has been conducted to accurately predict the effects of hail damage on soybean yields. Results from these studies are used by hail insurance companies to assess yield losses and consequent adjustment made to clients. The information in this NebGuide should be valuable to producers facing replant decisions, and may also be useful in cases of insect damage. Yield loss predictions …
