Estimation Of Relative Pesticide Leaching In Nebraska Soils, P. J. Shea, L. N. Mielke, W. D. Nettleton Mar 1992

Estimation Of Relative Pesticide Leaching In Nebraska Soils, P. J. Shea, L. N. Mielke, W. D. Nettleton

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

A computational procedure (RIPS, Relative Index for Pesticides and Soils) was developed as a conservative estimator of pesticide leaching and groundwater contamination based on soil and pesticide properties, and water table depth. RIPS values offer guidance in pesticide selection and identify situations where a detailed site-specific evaluation should be conducted.


A Soil And Vegetation Inventory And Analysis Of Three Nebraska Sandhills Range Sites, Donald F. Burzlaff Mar 1962

A Soil And Vegetation Inventory And Analysis Of Three Nebraska Sandhills Range Sites, Donald F. Burzlaff

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

This study was undertaken to inventory the soils and vegetation of certain areas of the Sandhills and to seek edaphic characteristics that may be the limiting factor in the distribution of various plant species. Information of this nature will permit formulation of more accurate management practices because of a refinement in delineation of range sites.


Nitrate Production As Affected By Grain-Crop Residues On The Surface Of The Soil, T. M. Mccalla, J. C. Russel Aug 1943

Nitrate Production As Affected By Grain-Crop Residues On The Surface Of The Soil, T. M. Mccalla, J. C. Russel

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

The purpose of this bulletin is to present the data on nitrate contents and nitrate production in tests where straw or stalk residues were left on the surface through subsurface tillage, as compared with check treatments where these residues were plowed under or were absent. Nine of these tests were at Lincoln, Nebraska, and one was at the Hastings, Nebraska, Hydrological Project. Two tests were conducted in 1939, four in 1941, and four in 1942.


Studies On The Relation Of The Nonavailable Water Of The Soil To The Hygroscopic Coefficient, F. J. Always Jun 1913

Studies On The Relation Of The Nonavailable Water Of The Soil To The Hygroscopic Coefficient, F. J. Always

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

These experiments were carried out in connection with and subordinate to various soil investigations, the object being to determine the relation of the final water content of the soil to the hygroscopic coefficient and to determine to what extent the moisture was removed from the different portions of the subsoil not penetrated by plant roots.
