University of Nebraska-Lincoln Extension: Historical Materials

This extension circular contains ecosystem definitions from abiotic to wildlife refuge.

G98-1370 Abandonment Planning For Earthen Manure Storages, Holding Ponds And Anaerobic Lagoons, Richard K. Koelsch

University of Nebraska-Lincoln Extension: Historical Materials

The purpose of this NebGuide is to define some critical issues to be addressed by an abandonment plan of an earthen manure storage, anaerobic lagoon or runoff holding pond.

A Nebraska construction permit for a Livestock Waste Control Facility (LWCF) requires a written plan defining possible abandonment procedures in the event the operation (and associated LWCF) is discontinued. The plan must be approved by the Nebraska Department of Environmental Quality (NDEQ) prior to permit issuance.

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.

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 …

G98-1354 Irrigating Corn, Brian Benham

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses corn irrigation strategies options and objectives.

There are over 16 million acres in harvested row crop production in Nebraska. About 8 million of these acres are irrigated. Corn occupies approximately 70 percent of the irrigated acreage, or 5.6 million acres. Given this, improving irrigation management on corn production can have significant positive impacts on the quantity and quality of Nebraska's most precious resource: water.

G98-1372 Management Recommendations For Blocked-End Furrow Irrigation, Dean E. Eisenhauer, Brian L. Benham

University of Nebraska-Lincoln Extension: Historical Materials

Proper blocked-end furrow irrigation management practices can minimize water application, irrigation costs and the leaching of agri-chemicals below the root zone.

The goal of every irrigator should be to apply the right amount of water uniformly to meet crop needs. To do this, irrigators need to know how much water is applied and where it goes. In other words, they need to know how uniformly the irrigation water infiltrates into the soil profile. Achieving a uniform water application is not easy when using furrow irrigation. However, with a better understanding of how irrigation system management affects water distribution and a …
