G98-1356 Polyacrylamide – A Method To Reduce Soil Erosion, C. Dean Yonts, Brian Benham

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes polyacrylamide, what it is, how it can be used to reduce soil erosion due to, irrigation and what water management changes must be considered.

Topsoil loss can mean a long-term reduction in soil productivity, crop yield and the life expectancy of downstream storage reservoirs. In the short term, producers are faced with reuse pits to clean or a buildup of soil at the lower ends of fields which must be redistributed. Measures must be taken to reduce or eliminate soil erosion and sustain Nebraska's soil resource.

Nf98-372 Preparation And Use Of Wheatgrass Stands After Crp And Associated Costs/Income — Part I, Patrick E. Reece, Tom Holman, David W. Cook

University of Nebraska-Lincoln Extension: Historical Materials

Wheatgrass species (Agropyron spp.) were seeded on many Conservation Reserve Program (CRP) acres in western Nebraska and adjoining states. These species included crested (A. cristatum, desertorum), intermediate (A. intermedium), pubescent (A. trichophorum) and western (A. smithii) wheatgrasses. Good to excellent stands of wheatgrass can be valuable forages sources for livestock during the spring, summer, or fall, however, accumulation of large amounts of poor quality residual herbage during 10-year CRP contract periods can reduce animal performance.

This NebGuide discusses field evaluations, results, recommended preparations, spring and summer grazing after CRP; and associated …

Ec98-151 Amaranth: Production Manual For The Central United States, Jane Sooby, David D. Baltensperger, Robert Myers, David Brenner, Richard Wilson, Charles Block

University of Nebraska-Lincoln Extension: Historical Materials

Amaranth is a small-seeded grain crop with a dramatic history. Once a staple in the diet of the Aztec Indians, today it is grown throughout the world. In the United States much of the production is small-scale and organic, grown mainly for the natural and health food markets. There also has been steady use of the crop for breakfast cereals, snack foods, and mass-produced multigrain bread products. Amaranth is a broadleaf plant well-adapted to a range of arid and humid environments. As a crop it fits into many dryland rotations, performing well following wheat, proso millet, or other grain crops. …

G96-1362 Soil Temperatures And Spring Planting Dates, Steven J. Meyer, Allen L. Dutcher

University of Nebraska-Lincoln Extension: Historical Materials

Dates on which soil temperatures reach a threshold value are presented as a spring planting guide for agronomic and horticultural producers.

For a seed to germinate it must have good contact with the soil and be placed in a favorable soil environment. A good soil environment is one that has suitable soil temperature, adequate soil moisture, good aeration, and for certain seeds, light. Conditions necessary for germination depend on the species and variety of seed being planted. Alone, none of these factors guarantee germination; rather it is the interaction of these factors that affects seed germination.

In Nebraska, soil moisture …
