G74-142 Harvesting And Preserving Hay Crop Silage, Rick Grant, Rick Stock

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes principles of successful hay crop harvest, silage preservation, management techniques to obtain high quality hay crop silage, and proper use of silage storage facilities.

Most hay (legume and grass) crops can be ensiled, or made into silage, successfully. For best feeding value and preservation, consider the special requirements for ensiling each crop.

Hays to be ensiled should be selected on the basis of economics. Which are the most profitable for supplying nutrients? For example, legumes have a relatively higher value for dairy herds than for beef finishing operations because of dairy cows' higher requirement for protein.

G74-121 Sandbur Control In Field Corn (Revised January 1999), Gail A. Wicks, Robert G. Wilson Jr.

University of Nebraska-Lincoln Extension: Historical Materials

Sandbur can be a major weed problem in cornfields if not properly controlled. This NebGuide discusses mechanical and chemical alternatives for controlling sandbur.

Sandbur is a problem weed on coarse to fine-textured soil. The North Platte Valley, southwest and west central Nebraska, and the Sandhills are areas in the state where sandbur is a major weed problem in corn. Sandbur seldom becomes a primary weed problem in eastern Nebraska. Both field (Cenchrus pauciflorus Benth.) and longspine [Cenchrus longispinus (Hack.) Fern.] sandbur grow in Nebraska.

G74-131 No-Till Corn In Alfalfa Sod, Alex R. Martin, Russell S. Moomaw

University of Nebraska-Lincoln Extension: Historical Materials

Nebraska produces about 1,740,000 acres of alfalfa annually. Corn or grain sorghum usually follows alfalfa in the crop rotation. The moldboard plow or chisel plow are commonly used to break up alfalfa sod for corn planting. The plow is a high consumer of energy, requiring about 2.25 gallons of diesel fuel per acre.

Research conducted in Nebraska has been used to develop a system in which the alfalfa is killed with herbicides and corn is planted directly into the sod without tillage. Plowing is eliminated and energy requirements can be reduced to about 1/4 that used in the conventional plow …

G74-113 A Quick Test For Atrazine Carryover (Revised March 1989), Alex Martin, R.N. Stougaard, Patrick J. Shea

University of Nebraska-Lincoln Extension: Historical Materials

How can you tell if you have atrazine carryover in your fields? Plants grown in soil samples can tell.

Residues of atrazine may remain in the soil and affect some susceptible crops the next year. Crops most often affected include soybeans, field beans, sugarbeets, alfalfa, oats, wheat and many broadleaf horticultural crops.

Attempts to predict the extent of carryover and damage to sensitive crops the year following atrazine use have been only partially successful. The rate of atrazine disappearance and, therefore, the amount remaining the next year, is affected by soil texture, pH and organic matter content, as well as …
