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.


G73-15 Handling Feed Moisture In Ration Formulation And Inventory Control (Revised December 1983), Paul Q. Guyer Jan 1973

G73-15 Handling Feed Moisture In Ration Formulation And Inventory Control (Revised December 1983), Paul Q. Guyer

University of Nebraska-Lincoln Extension: Historical Materials

Nutritional quality control begins with knowing and adjusting for variation in the moisture content of feed ingredients. Moisture variations in feeds are almost always of more importance than variations in protein, mineral, and energy. Inventory control is affected by moisture content of feeds. Some feeds on hand are constantly changing in moisture content, and these changes frequently lead to financial losses when a price adjustment is not made for moisture losses.
