G93-1146 Cover Crop Use In Crop Production Systems, Robert G. Wilson Jr., John A. Smith, Russell Moomaw

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes how cover crops can be integrated into various cropping systems. Agricultural producers are hearing more about cover crops, but many are unsure how such plants might be used in current crop production systems. Cover crops are legumes, cereals or an appropriate mixture. They are grown specifically to protect soil from erosion, protect emerging crops from blowing soil particles, improve soil structure, enhance soil fertility, reduce nutrient leaching, recycle nutrients and suppress weeds. A number of plant species could be used, but they must be successfully integrated into a diverse number of cropping systems used in Nebraska. Nebraska …


G93-1126 Crambe Production, Lenis Alton Nelson, Alan Grombacher, David D. Baltensperger Jan 1993

G93-1126 Crambe Production, Lenis Alton Nelson, Alan Grombacher, David D. Baltensperger

University of Nebraska-Lincoln Extension: Historical Materials

This is a complete guide to the specifics of crambe production, from seedbed preparation to harvesting, storage and marketing. Crambe (Crambe abyssinica) is an oil crop from the mustard family. The seed contains 30 to 35 percent oil with 40 to 60 percent erucic acid in the oil. The erucic acid oil content of crambe is 8-9 percent more than that of rapeseed.


G93-1133 Estimating Percent Residue Cover Using The Line-Transect Method, David P. Shelton, Roger Kanable, Paul J. Jasa Jan 1993

G93-1133 Estimating Percent Residue Cover Using The Line-Transect Method, David P. Shelton, Roger Kanable, Paul J. Jasa

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes how to use the line-transect method to estimate the percentage of the soil surface covered with crop residue.

Crop residue left on the soil surface is one of the easiest and most cost-effective methods of reducing soil erosion. Research in Nebraska and other midwestern states has shown that leaving as little as 20 percent of the soil surface covered with crop residues can reduce soil erosion by one-half of what it would be from residue-free conditions. Greater amounts of residue cover will further reduce erosion.
