Ec92-124 Nebraska Handbook Of Range Management, James L. Stubbendieck, Patrick E. Reece
Ec92-124 Nebraska Handbook Of Range Management, James L. Stubbendieck, Patrick E. Reece
University of Nebraska-Lincoln Extension: Historical Materials
Every Nebraskans should be interested in rangeland. The plants, soil, and water are the foundation of Nebraska's economy and quality of life. Rangeland is one of Nebraska's most important and valuable natural resources because it:
• produces forage for livestock and wild game;
• provides a varied habitat for many wildlife species;
• protects the soil from wind and water erosion;
• preserves a "germplasm bank" for many plant species that may become important for yet unknown uses;
• purifies and enhances the environment by cleasing the air, filtering the runoff to streams, increasing the intake of precipitation, and aiding …

Canola, which produces a vegetable oil low in saturated fat, has potential for becoming an alternative crop for Nebraska agriculture. Canola produces an oil that has the lowest saturated fat content of any vegetable oil. Today, there is an increasing demand for this oil by diet-conscious consumers. In 1985, the U.S. Food and Drug Administration (FDA) recognized rapeseed and canola as two different species, based on their content and uses. Rapeseed oil is used in industry, while canola oil is used for human consumption. High erucic acid rapeseed (HEAR) oil contains 22-60 percent erucic acid, while low erucic acid rapeseed …

University of Nebraska-Lincoln Extension: Historical Materials
Characteristics of soil-applied herbicides are discussed, including site of uptake by weeds, solubility, adsorption, persistence, leaching potential, photodecomposition, and volatility. For best performance, preemergence and preplant herbicides must be placed in the top 0 to 3 inches of soil. Placement is important because the herbicide must enter the germinating weed seedling in order to kill it. Herbicides can be blended into the soil by mechanical incorporation, rainfall, or sprinkler irrigation, depending on the herbicide. Herbicide characteristics that determine their performance are site of uptake by weeds, solubility, adsorption, persistence, leaching potential, photodecomposition, and volatility. An understanding of these factors will …
