Properties Of Soils In The Solid Set Irrigation Area Of The Sandhills Agricultural Laboratory, David T. Lewis
Properties Of Soils In The Solid Set Irrigation Area Of The Sandhills Agricultural Laboratory, David T. Lewis
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
The introduction of irrigated agriculture and the attendant increase in intensity of land use for agricultural purposes in the Sandhills region of Nebraska requires additional data regarding soils in the area. This work investigated landscape relationships and some of the morphological, physical, chemical, and mineralogical properties of the soil in one irrigated valley. The soils in this valley contain greater amounts of silt and clay than do the soils on the nearby dunes. In addition, some of the valley soils contain layers of much higher clay content and corresponding cation exchange and water holding capacity than the dunal soils and …

Modeling Spring Wheat Production As Influenced By Climate And Irrigation, V. Philip Rasmussen Jr.
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
A model has been developed that predicts spring wheat grain and dry matter yield. Preliminary tests show very favorable results when predicting grain yield in two different climatic regimes, one being a dryland and another being an irrigated area. The strengths of the model lie in its simplicity, relatively available input data, and low computer processing time cost. Weakness of the model stem from the assumptions that allow its simplicity. The basic assumption in the model is that grain and dry matter yield can be related to the ratio of actual to potential transpiration, computed for each of five phenological …
