Variety selection is a fundamental element in a sound crop production program. This report contains variety recommendations, descriptions, and yield data for the spring-seeded small grains – hard red spring wheat, oat, and barley, along with the fall-seeded small grain –hard red winter wheat. Key factors in variety selection include yield, yield stability, maturity, straw strength, height, test weight, quality, and disease resistance. Yield is an important factor; however, a variety with good disease resistance, straw strength, and high grain quality may be more profitable in some cases than the highest yielding variety. Disease resistance information is based on reactions …

The key to business success—whether operating a ranch or a Fortune 500 company—lies in management and planning. It’s the ability to have foresight, to carefully evaluate and choose appropriate new concepts and technologies, and to implement a well thought- out plan that complements all aspects of the business. The highly-respected former CEO and chairman of General Electric Jack Welch put it this way: Good business leaders create a vision, articulate the vision, passionately own the vision, and relentlessly drive it to completion. How does that description apply to you? Are you a visionary business leader for your ranch enterprise? Or …
Potential Use Of The Conservation Security Program To Encourage Diverse Crop Rotations In Eastern South Dakota, Thomas Dobbs, Nicholas J. Streff
Potential Use Of The Conservation Security Program To Encourage Diverse Crop Rotations In Eastern South Dakota, Thomas Dobbs, Nicholas J. Streff
Economics Research Reports
A central concern in many discussions of ecological sustainability in agricultural regions of the U.S. Midwest and Great Plains is that of crop system diversity. Many factors have contributed to the loss of crop system diversity over that last half-century (Dumke and Dobbs), one of which is public policy. The U.S. Farm Security and Rural Investment Act of 2002 ('2002 Farm Bill') provided for a new agri-environmental program that could have potential to help restore some of the crop system diversity that has been lost. The Conservation Security Program (CSP) is that program. This report, drawn from a Master of …
Sorption-Desorption Of Imidacloprid And Its Metabolites In Soil And Vadose Zone Materials, Sharon V. Papiernik, William C. Koskinen, Lucia Cox, Pamela J. Rice, Sharon A. Clay, Nancy R. Werdin-Pfisterer, Kristen A. Norberg

Sorption-desorption is one of the most important processes affecting the leaching of pesticides through soil because it controls the amount of pesticide available for transport. Subsurface soil properties can significantly affect pesticide transport and the potential for groundwater contamination. This research characterized the sorption-desorption of imidacloprid (1-[(6-chloro-3-pyridinyl)-methyl]-Nnitro-2-imidazolidinimine) and three of its metabolites, 1-[(6-chloro-3-pyridinyl)methyl]-2-imidazolidinone (imidacloprid-urea), 1-[(6-chloro-3-pyridinyl)methyl]-4,5-dihydro-1H-imidazol-2-amine (imidaclopridguanidine), and 1-[(6-chloro-3-pyridinyl)methyl]-1H-imidazol-2-amine (imidacloprid-guanidine-olefin), as a function of changing soil properties with depth in two profiles extending from the surface to a depth of 1.8 or 8 m. Sorption of each compound was highly variable and hysteretic in all cases. Normalizing the sorption coefficients (Kf) …

The Prairie Pothole Region (PPR) contains 5-8 million small wetlands and is one of the most ecologically valuable freshwater resources of the Nation. These wetlands provide abundant ecosystem services, including groundwater recharge, water for agriculture, water purification, and recreation. The PPR is best known as the “duck factory” of North America. By some estimates, this region produces over 50% of the ducks in North America.
