Conterminous United States Crop Field Size Quantification From Multi-Temporal Landsat Data, Lin Yan Dr., David P. Roy
Conterminous United States Crop Field Size Quantification From Multi-Temporal Landsat Data, Lin Yan Dr., David P. Roy
GSCE Faculty Publications
Agricultural field size is indicative of the degree of agricultural capital investment, mechanization and labor intensity, and it is ecologically important. A recently published automated computational methodology to extract agricultural crop fields from weekly 30 m Web Enabled Landsat data (WELD) time series was refined and applied to a year of Landsat 5 Thematic Mapper (TM) and Landsat 7 Enhance Thematic Mapper Plus (ETM +) acquisitions for all of the conterminous United States (CONUS). For the first time, spatially explicit CONUS field size maps and derived information are presented. A total of 4,182,777 fields were extracted with mean and median …

This paper summarises discussions by invited speakers during a special session at the 6th North American Duck Symposium on wetland issues that affect waterfowl, highlighting current ecosystem challenges and opportunities for the conservation of waterfowl in North America. Climate change, invasive species, U.S. agricultural policy (which can encourage wetland drainage and the expansion of row-crop agriculture into grasslands), cost and competition for water rights, and wetland management for non-waterfowl species were all considered to pose significant threats to waterfowl populations in the near future. Waterfowl populations were found to be faced with significant threats in several regions, including: the Central …
Preference Of White-Tailed Deer For Corn Hybrids And Agricultural Husbandry Practices During The Growing Season, Joshua A. Delger, Kevin L. Monteith, Lowell E. Schmitz, Jonathan A. Jenks
Preference Of White-Tailed Deer For Corn Hybrids And Agricultural Husbandry Practices During The Growing Season, Joshua A. Delger, Kevin L. Monteith, Lowell E. Schmitz, Jonathan A. Jenks
Natural Resource Management Faculty Publications
Damage to field corn (Zea mays) by white-tailed deer (Odocoileus virginianus) can be substantial, resulting in millions of dollars lost annually. Numerous methods exist to minimize deer depredation, but all have met with varying degrees of success. Currently, little information is available on preference of white-tailed deer for corn hybrids during the growing season and how that preference might affect depredation patterns. We used adult female white-tailed deer in captivity to study the effect of herbicide treatments on deer-use (treatment versus no treatment) of corn in 2005 and to document preference among specific corn hybrids in …
Agriculture Policy Decisions: A Perspective From South Dakota Farmers And Ranchers, Larry Janssen, Mark Edelman
Agriculture Policy Decisions: A Perspective From South Dakota Farmers And Ranchers, Larry Janssen, Mark Edelman
Economics Research Reports
Federal government policies greatly affect farmers and ranchers. Most South Dakota farmers and ranchers favor changes in the process used to make farm policy decisions but are split on the desirable future direction of farm commodity programs. A majority of producers favor existing or modified loan rate, target price, and farmer owned grain reserve program but are sharply divided on payment-in-kind (PIK) programs. Most producers favor the market growth provided by world trade but are not willing to give up minimum trade barriers, these barriers provide some cushion from the instability caused by international trade system. In addition, farmers are …
The Changing Structure Of South Dakota Agriculture, Larry Janssen, Mark Edelman
The Changing Structure Of South Dakota Agriculture, Larry Janssen, Mark Edelman
Economics Research Reports
The purpose of this report is to present and analyze recent structural trends in South Dakota Agriculture and to outline major implications of these trends. In the report, major forces underlying the recent structural trends in South Dakota agriculture are briefly discussed. Recent South Dakota trends are then presented and analyzed in the following order: (1) Declining farm numbers (2) Increasing farm size in acres (3) Increasing sales volume and concentration (4) Land tenure and ownership trends (5) Farm corporations in perspective (6) Greater specialization and concentration of livestock enterprises (7) Greater reliance on debt capital and other changes in …
Implementation Of A Microprocessor Based Accounting System For Agricultural Uses, Herbert Allen, Duane Sander, James Beals
Implementation Of A Microprocessor Based Accounting System For Agricultural Uses, Herbert Allen, Duane Sander, James Beals
Economics Research Reports
This study has demonstrated the feasibility of using microcomputers on the farm or in the home to solve problems involving manipulation of large quantities of data or detailed mathematical procedures. A microcomputer with at least 32,000 words of memory and magnetic disk storage is recommended for efficient data processing. This capacity is required for programs of the type presented in this publication. A printer with at least an 80 character line is an essential feature. It is frequently necessary to have hard copy printouts of financial statements or cash flows in order to document the farm financial position. Programs may …
