South Dakota Beef Cow-Calf Producer Management Practices, Donald Taylor, Dillon M. Feuz Dec 1992

South Dakota Beef Cow-Calf Producer Management Practices, Donald Taylor, Dillon M. Feuz

Economics Research Reports

This research report is based on the results of a mail survey of randomly selected South Dakota beef cow-calf operators undertaken during late 1991. The purpose of the survey was to determine the nature of management practices followed by the state's cow-calf producers and whether those practices differ by size and/or location of herd. Attention was given to producers' overall cowcalf, breeding, feeding, and health management practices.


Water Institutional Structure In The Upper Midwest, Douglas Franklin, John R. Powers, Ardelle Lundeen Jun 1992

Water Institutional Structure In The Upper Midwest, Douglas Franklin, John R. Powers, Ardelle Lundeen

Economics Research Reports

The upper Great Plains and Mountain States of the United States use a substantial quantity of water. Primary uses are irrigation, domestic, and industrial. The amount of water used is increasing as population grows, as more users exercise water rights, as farmers implement the use of irrigation to reduce risk, and as the states' economies become more diverse. Within the Upper Midwest, there is both geographic and temporal variability of water supply, resulting in various degrees of scarcity relative to the quantities demanded. The allocation method for the available water must be appropriate for these variations.


Farm Management Innovators: Characteristics Of Eastern South Dakota Farm Operators, Douglas Franklin, Abdirizak Ahmed Jun 1992

Farm Management Innovators: Characteristics Of Eastern South Dakota Farm Operators, Douglas Franklin, Abdirizak Ahmed

Economics Research Reports

Sustainable farming and reduced or low tillage are the technical and management innovations examined in the paper. A stratified survey of producers in a six county area of eastern South Dakota was conducted. The specific characteristics examined are operator age, education, gross income, percentage of rented land and cropping acres. The paper analysis the adopters and nonadopters of such technical and management innovations on the farm.


Trends In Water Use In The Upper Midwest, Douglas Franklin, John R. Powers, Ardelle Lundeen Jun 1992

Trends In Water Use In The Upper Midwest, Douglas Franklin, John R. Powers, Ardelle Lundeen

Economics Research Reports

The upper Great Plains and Mountain States of the United States withdraws a substantial quantity of water, exceeding 40 billion gallons of water per day (45 million acre feet of water per year). Primary uses are irrigation, domestic, and industrial. The amount of water used is increasing as population grows, as more users exercise water rights, as farmers implement the use of irrigation to reduce risk, and as the state's economies become more diverse. Within the Upper Midwest there is both geographic and temporal variability of water supply, resulting in various degrees of scarcity relative to the quantities demanded. The …


South Dakota Agricultual Land Values And Rental Rates: 1992, Larry Janssen Jun 1992

South Dakota Agricultual Land Values And Rental Rates: 1992, Larry Janssen

Economics Research Reports

South Dakota's agricultural land values increased 3.4% in 1991, paced by strong increases in farmland values in the north central region. Farmland values declined slightly (-1.1%) in the southeast region, the only region with reported declines. Average agricultural land values (as of February 1, 1992) vary from $533 per acre in the southeast region, to $225 per acre in the central region to $95 per acre in northwest South Dakota. These are key findings from the SDSU 1992 South Dakota Farm Real Estate Market Survey reports. In each region, per acre values are highest for irrigated land, followed in descending …


Alternative Road Networks For A South Dakota Township, Charles Lamberton Jun 1992

Alternative Road Networks For A South Dakota Township, Charles Lamberton

Economics Research Reports

The network of roads within any defined region is necessarily connected to the network of each adjacent region. Therefore, sections of road which might be added to, or deleted from, the existing network can result in changes in consumers' travel and routing and their use of the remaining network. This can result in significant changes in the costs and benefits of the network for consumers and major changes in the cost of supplying the road network services. The study of the adequacy of a rural road network is therefore necessarily a study of a complex, interdependent system. Consideration of the …

Grain Basis Patterns For Selected Locations In South Dakota, Bashir Qasmi

Economics Research Reports

For successful marketing, and merchandising in commodity markets, it is important to understand the relationship between cash and futures contract prices. The principal measure for relating cash and futures price is local cash basis or "Basis".


South Dakota's Rural Roads, Charles E. Lamberton Feb 1992

South Dakota's Rural Roads, Charles E. Lamberton

Economics Research Reports

The rural transportation system consists of a combination of modern, heavy farm machinery, trucks, and personal vehicles driven over earth, gravel and bituminous roads. These roads were often originally designed for use by horse and wagon. The evolution of transportation and agricultural technologies has changed the demands upon the road system and caused this mismatch between original road design and modern vehicles and equipment. Increased farm production and decreased farm numbers are reflected in fewer rural residents who make more trips and carry heavier loads. While the decline in the number of rural residents implies that fewer miles of rural …
