University of Nebraska-Lincoln Extension: Historical Materials

A center-pivot sprinkler system is a medium cost, low labor irrigation method. A few of these systems have been high cost, high labor irrigation methods. Consideration of a few details in the purchase of the system can help prevent the high cost and/or high labor.

Many different types of systems are available today. Consideration must be given to soil texture and slope of the field to be irrigated with the center-pivot. This publication covers what to look for when purchasing a center-pivot sprinkler system.

G74-123 Weed Control In Reduced Tillage Corn (Revised May 1982), Russell Moomaw, Alex Martin, David P. Shelton

University of Nebraska-Lincoln Extension: Historical Materials

Weeds compete with corn plants for water, nutrients and light. Historically, the soil has been extensively tilled to prepare a seedbed and to lessen or remove weed competition. This tillage centered around moldboard plowing.

Results of a recent survey indicate that most Nebraska farmers now use some form of reduced tillage, with the moldboard plow being used on only 11 percent of Nebraska's corn acreage. Reduced tillage is used in many forms.

This NebGuide discusses how to control weeds using the different types of tillage systems.
