Boundaries and Water: Allocation and Use of a Shared Resource (Summer Conference, June 5-7)

Conference organizers and/or faculty included University of Colorado School of Law professors David H. Getches, Lawrence J. MacDonnell and Charles F. Wilkinson.

Boundaries and Water: Allocation and Use of a Shared Resource is the topic of the Center's annual summer program on water this June. Most of the major rivers in the western United States are shared between two or more states. Often tribal governments play an important role in water allocation and use decisions. International considerations also may be involved in some cases. These interjurisdictional issues extend to groundwater as well as surface water.

This conference will provide the …

Effect Of Burning On Germination Of Tallgrass Prairie Plant Species, Sherry R. Rohn, Thomas B. Bragg

Biology Faculty Proceedings & Presentations

Seeds from 10 prairie plant species of burned and unburned portions of three tallgrass prairies were collected and tested for germinability. Germination of big bluestem (Andropogon gerardii Vitman) consistently averaged higher with burning. Indiangrass (Sorghastrum nutans L.) and sideoats grama [Bouteloua curtipendula (Michx.) Torr.] averaged 5% higher with burning on two of the three sites, although for indiangrass average germination for all three sites was 7% lower. Species for which germination declined with burning were false sunflower [Heliopsis helianthoides (L.) Sweet var. scabra (Dun.) Fern.], -13%; whole leaf rosinweed (Silphium integrifolium Michx.), -10%; and white …

Tallgrass Prairie Remnants Of Eastern Nebraska, Judith F. Boettcher, Thomas B. Bragg

Biology Faculty Proceedings & Presentations

Ten eastern Nebraska tallgrass prairie remnants were evaluated up to four times during the 1979 growing season to assess vegetative composition and the effects of mowing, topographic and size differences, and season of evaluation. Frequent mowing resulted in a reduced canopy cover of some species, such as big bluestem (Andropogon gerardii Vitman) (21% lower with frequent mowing), but increased cover of others, particularly the introduced species smooth brome (Bromus inermis Leyss. subsp. inermis) (35% higher cover with frequent mowing). In addition, frequent mowing resulted in a higher proportion of disturbance species. Comparing the time of mowing, canopy …

G89-948 Safe Operation Of Compact Tractors, Robert D. Grisso, Rollin Schnieder

University of Nebraska-Lincoln Extension: Historical Materials

Follow these safety tips and maintenance procedures for checking, servicing and operating compact tractors to extend their life and reduce breakdowns and accidents.

Lawn and turf maintenance is easier because of modern compact tractors, but carelessness can spell trouble.

Most tractors used in grounds care can be classified into three size groups: 1) riding lawn mowers (3 to 8 horsepower) which are fitted with a mower and usually do not have other equipment or attachments that could be mounted separately; 2) lawn and garden or compact tractors (7 to 40 horsepower) that can be mounted with a variety of tools …

G89-901 Understand Your Soil Test: Sulfur, K.D. Frank, Delno Knudsen

University of Nebraska-Lincoln Extension: Historical Materials

Factors leading to sulfur deficiency, soil and water tests, soil test interpretation and fertilizer materials that contain sulfur are covered here.

Sulfur, one of the macro-nutrients, may be deficient in some sandy soils but usually is plentiful in other soils of the state. The amounts contained by healthy crops are on the same order as phosphorus, ranging from 0.2 percent to .5 percent sulfur. It is a component of certain amino acids, and so is part of several proteins essential for plants and animals.

G89-899 Weed Control In No-Till Corn, Grain Sorghum And Soybean Production, R.S. Moomaw, Alex Martin, R.N. Stougaard, Fred Roeth, G.A. Wicks, Robert N. Klein, Paul J. Jasa

University of Nebraska-Lincoln Extension: Historical Materials

Tips for successful no-till weed control, weed control principles for no-till row crop production, and no-till row crops planted into legume or small grain residues are covered here. Soil erosion by wind and water is a strong societal concern in our state and nation. Current estimates are that more than 100 million tons of topsoil are eroded annually in Nebraska, with 75 percent of that coming from row crop areas. Nebraska farmers have been implementing changes in their crop production practices to reduce soil erosion.

G89-908 Controlling Snake Problems Around Homes, Ron J. Johnson

University of Nebraska-Lincoln Extension: Historical Materials

Controlling snake problems around residences is covered here. Occasionally people encounter snakes around their homes or in other places, and wonder what to do about the snakes or whether they are dangerous. In nearly all cases, these are harmless types such as garter snakes or bullsnakes. However, Nebraska does have four kinds of poisonous snakes: the prairie rattlesnake, timber rattlesnake, small rattlesnake, copperhead.

G89-923 Windbreak Maintenance And Renovation, Jon Wilson, Mike Kuhns

University of Nebraska-Lincoln Extension: Historical Materials

What are you doing to maintain your windbreak? Is renovation necessary? This NebGuide can help you decide.

Windbreaks are integral parts of many Nebraska farming and ranching operations. They protect man, animals, crops and buildings from cold winter winds, hot summer winds, and deep snows. Windbreaks prevent wind erosion and provide wildlife habitat.

All windbreaks, even well-designed ones, need regular maintenance. Some windbreaks, especially those that are older or neglected, may need more drastic treatment or renovation.
