School of Natural Resources: Documents and Reviews

In July 2003, the School of Natural Resource Sciences was merged with the Conservation and Survey Division and the Water Center Nebraska State Survey. This merger produced the School of Natural Resources (hereafter referred to as the "School") in its current form. The University of Nebraska-Lincoln requested a ten-year review of the School's programs and activities. The review was administered by the Cooperative State Research, Education and Extension Service (CSREES) in cooperation with the University of Nebraska-Lincoln's Institute of Agriculture and Natural Resources, the College of Agriculture, and the School.

The review document is divided into nine sections. The first …

Herbicide Loading To Shallow Ground Water Beneath Nebraska’S Management Systems Evaluation Area, Roy F. Spalding, Darrell G. Watts, Daniel D. Snow, David A. Cassada, Mary E. Exner, James S. Schepers

Nebraska Water Center: Faculty Publications

Better management practices can counter deterioration of ground water quality. From 1991 through 1996 the influence of improved irrigation practices on ground water pesticide contamination was assessed at the Nebraska Management SystemsEvaluation Area. Three 13.4-ha corn (Zea mays L.) fields were studied: a conventional furrow-irrigated field, a surge-irrigated field and a center pivot–irrigated field, and a center pivot–irrigated alfalfa (Medicago sativa L.) field. The corn fields received one identical banded application of Bicep (atrazine [6-chloro-N-ethyl-N’-(1-methylethyl)-1,3,5-triazine-2,4,-diamine] _ metolachlor [2-chloro-N-(2-ethyl-6-methylphenyl)-N-(2-methoxy-1-methylethyl) acetamide]) annually; the alfalfa field was untreated. Ground water samples were collected …

Herbicides In Ground Water Beneath Nebraska’S Management Systems Evaluation Area, Roy F. Spalding, Mary E. Exner, Daniel D. Snow, David A. Cassada, Mark E. Burbach, Stephen J. Monson

Nebraska Water Center: Faculty Publications

Profiles of ground water pesticide concentrations beneath the Nebraska Management Systems Evaluation Area (MSEA) describe the effect of 20 years of pesticide usage on ground water in the central Platte Valley of Nebraska. During the 6-yr (1991–1996) study, 14 pesticides and their transformation products were detected in 7848 ground water samples from the unconfined water table aquifer. Triazine and acetamide herbicides applied on the site and their transformation products had the highest frequencies of detection. Atrazine [6-chloro-N-ethyl-N’-(1-methylethyl)-1,3,5-triazine-2,4,-diamine] concentrations decreased with depth and ground water age determined with ³H/³He dating techniques. Assuming equivalent atrazine …
