Effects Of No-Tillage Fallow As Compared To Conventional Tillage In A Wheat-Fallow System, C. R. Fenster, G. A. Peterson Oct 1979

Effects Of No-Tillage Fallow As Compared To Conventional Tillage In A Wheat-Fallow System, C. R. Fenster, G. A. Peterson

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The benefits of reducing tillage by use of herbicides for weed control emphasizes why research was started to study a fallow system where all tillage was replaced by herbicides. Wheat planting was then the only soil disturbing operation. Objectives of the research were to compare the effects of no-tillage (chemical), stubble-mulch and plow (bare fallow) systems of fallow on: 1. Grain yield. 2. Grain protein. 3. Residue retention. 4. Soil nitrate-nitrogen accumulation. 5. Soil water accumulations during fallow. Data presented are in the form of a progress report. These experiments will continue.

The Mississippian And Pennsylvanian (Carboniferous) Systems In The United States-Nebraska, R. R. Burchett Jan 1979

The Mississippian And Pennsylvanian (Carboniferous) Systems In The United States-Nebraska, R. R. Burchett

Conservation and Survey Division: Faculty and Staff Publications

Nebraska is underlain by rocks of Mississippian and (or) Pennsylvanian age in all but the extreme northeastern part of the State. Only some of the Upper Pennsylvanian strata are exposed; outcrops of these rocks are limited to southeaster Nebraska. This work is published as Conservation and Survey Division GSI-5 and as U.S. Geological Survey PP-1110-P.

Properties Of Soils In The Solid Set Irrigation Area Of The Sandhills Agricultural Laboratory, David T. Lewis Sep 1976

Properties Of Soils In The Solid Set Irrigation Area Of The Sandhills Agricultural Laboratory, David T. Lewis

Nebraska Agricultural Experiment Station: Historical Research Bulletins

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 …

Rates Of Water Entry Into The Subsoil Of Several Soil Series In Nebraska, David T. Lewis Jan 1975

Rates Of Water Entry Into The Subsoil Of Several Soil Series In Nebraska, David T. Lewis

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Rates of water entry were measured for 11 soil series representing many of the soils in parts of Nebraska where urban growth is most intensive. The wetting procedure in making the tests is critical and a 24 hour wetting time as usually recommended is not adequate for all soils if the percolation test is made during a dry season. Rates of water entry differed among soils even though a large amount of variation was evident within the same soil series. Statistical analysis showed a highly significant negative relationship between both clay content and bulk density and rates of water entry. …
