Ec88-116 Universal Soil Loss Equation: A Handbook For Nebraska Producers, A. J. Jones, D. Walters, W. G. Hance, Elbert C. Dickey, J.R. Culver

University of Nebraska-Lincoln Extension: Historical Materials

Tons of soil are lost from agricultural fields in Nebraska each year as a result of water erosion. The accelerated loss of topsoil reduces the availability of plant nutrients and water needed for optimum crop production. In addition, the eroded soil frequently moves into surface waters causing sediment to be deposited in streams and reservoirs and nutrients to be released into other biological systems. The purposes of this workbook are to provide an understandng of how soil erosion estimates are determined, to estimate erosion control resulting from numerous cropping systems, and to inform the producer of alternative practices which may …

“The Poor People Had Suddenly Become Rich” A Boom In Maine Wheat, 1793-1815, Jamie H. Eves

Maine History

The article discusses the important role played in the surreptitious trade in wheat to the British Empire during the Napoleonic Wars. Its European supplies choked off by tariffs and embargoes, Britain turned to Ireland and to the United States for grain.

Use Of Soybean Meal, Raw Soybeans, & Heat-Treated Soybeans As Protein Supplements With & Without Niacin For Dairy Cows In Early Lactation, Daniel Aguilar

Masters Theses & Specialist Projects

Twenty three cows with an average of 2.7 lactations were used to measure the effects of different protein sources (soybean meal, soybeans, and heat-treated soybean) and supplementation with niacin on milk production, milk components (protein, fat, somatic cell counts), 4% fat corrected milk, solid corrected milk, dry matter intake, body weight changes, and rumen volatile fatty acids (acetate, propionate, butyrate).

Diets affected performance of cows. The results indicate, in general, that feeding heat-treated soybean and soybean meal to lactating dairy cows in early lactation resulted in greater milk production, milk protein, dry matter intake and less loss of body weight …

Clonal Foraging In Perennial Wheatgrasses: A Strategy For Exploiting Patchy Soil Nutrients, L. D. Humphrey, D. A. Pyke

Aspen Bibliography

1 Foraging by means of plasticity in placement of tillers in response to low- and high- nutrient patches was examined in the rhizomatous wheatgrass Elymus lanceolatus ssp. lanceolatus. Its ability to exploit soil nutrient patches was compared to that of the closely related but caespitose E. lanceolatus ssp. wawawaiensis. 2 Clones of 14 genets of each taxon were planted in boxes consisting of two 30 x 30 cm cells: the 'origin cell' where clones were planted, and the adjacent 'destination cell', with each cell containing soil with either low or high levels of nutrients. 3 The rhizomatous taxon, which can …

Direct Seeding Trees On Farmland In The Western Australian Wheatbelt, J P. Piggott, P H. Brown, M M. Williams

Resource management technical reports

Field and nursery experiments were conducted to determine suitable species, weed control methods, sowing times and seeding techniques. Sowing time was the most significant variable evident in the field experiments. Trees sown in the winter months of June and July out-performed later sowing times. Early sowing of trees in areas of low seasonal rainfall appears to offer considerable advantages for successful establishment over late sowing.

Drains : A Method Of Financially Assessing Drains Used To Mitigate Waterlogging In South-Western Australia, John S. Salerian, D J. Mcfarlane

Resource management technical reports

Seepage interceptor drains are often effective in mitigating waterlogging in duplex (sand over clay) soils on hill slopes in the sout-west. Spoon and W drains are sometimes effective in removing excess surface waters form clay flats.

This report outlines a method to determine the long-term (1 to 20 years) cost-effectiveness of installing drains to mitigate waterlogging for each individual situation.

The Impacts Of Alternative Electric Rate Structures For Irrigation: Cam-Wal Rec, Donald Taylor

Examination Of Farm Bankruptcy Debtors And Their Creditors, Larry Janssen, Brian Schmiesing

Economics Research Reports

Agricultural financial conditions and farm reorganization options have been analyzed extensively by agricultural economists, but analysis of actual reorganization bankruptcy filings has not been completed. This study contains analysis of 219 Chapter 11 farm filings in South Dakota from 1980-1985 and documents financially related characteristics of these producers and their secured. impaired and unsecured creditors. Discriminant analysis is used to examine the predictive value of initial filing data on eventual court disposition of farm Chapter 11 cases. Major provisions of Federal Bankruptcy Chapter 11 and 12 are compared. South Dakota agricultural lenders' reactions concerning impacts of Chapter 12 on credit …

Cost Of Production And Net Returns For Alternative Farming Systems In Northeastern South Dakota: 1986 And "Normalized" Situations, Thomas Dobbs, Lyle A. Weiss, Mark G. Leddy

Economics Research Reports

This report is a product of the initial year of research under South Dakota State University (SDSU) Agricultural Experiment Station Project H-076. entitled "Economics of Farming Systems Alternatives in Eastern South Dakota". The overall objective of this research project is to determine the economic practicality in eastern South Dakota of "alternative" farming systems which may entail less use of chemical fertilizers. pesticides. and herbicides than do "conventional" systems. The initial step in achieving that overall objective is to make preliminary estimates of crop enterprise and farming system costs and returns. We have done this for two sets of farming systems …

Post-Effect Of Ammonia On Energetics Of Laying Hens At High Temperatures, Hongwei Xin, James A. Deshazer, M. M. Beck

Hongwei Xin

Leghorn layers were monitored for heat loss, feed intake, egg production and respiratory rate at various environmental temperatures (TJ after first being exposed to aerial ammonia (NH3). The initial exposure was to 10 or 60 ppm NH3 at a T, of 25 °C for 30 days to simulate a winter environmental condition in a poultry facility. Hens were then allowed to recover in an environment of 5 ppm of NH3 at a T^ of 22 °C for seven days to simulate a spring environmental condition. Birds were then placed individually in a partitional calorimeter free of NH3 at 25, 29, …
