Understanding How Agricultural Intensification Impacts Ring-Necked Pheasant Distribution And Survival In Eastern South Dakota, Hilary R. Kauth
Understanding How Agricultural Intensification Impacts Ring-Necked Pheasant Distribution And Survival In Eastern South Dakota, Hilary R. Kauth
Electronic Theses and Dissertations
Historically, pheasants (Phasianus colchicus) have thrived in South Dakota in conjunction with successful land retirement programs or early farming practices through the 1950s, which created interspersions of agriculture and native landscapes that were ideal for pheasants. Recently, the Prairie Pothole ecosystem has undergone rapid agroeconomic expansion, effectively reducing ideal interspersions of native prairie and cropland into agriculturally homogeneous landscapes. Indices of pheasant abundance have suggested persistent population declines since 2008, raising concerns regarding landscape suitability. Our goal was to understand how agriculture intensification impacts pheasant ecology. The objectives were to: 1) estimate overwinter hen probability of survival, resource …
Adoption Of Conservation Practices And Precision Technologies In South Dakota: An Empirical Analysis, Allen P. Deutz
Adoption Of Conservation Practices And Precision Technologies In South Dakota: An Empirical Analysis, Allen P. Deutz
Electronic Theses and Dissertations
Advances in conservation agriculture and precision agriculture technology practices have contributed to the adoption of conservation practices that reduce externalities from agricultural production, but this conversion was usually coupled with economic incentive, whether from increases in fertility and yield, or payments for on farm retirement or restoration practices. This study expands on this theme, evaluating the connection between conservation and the increased use of various precision agriculture technologies. The study uses survey data collected from South Dakota farmers and ranchers, with responses from 28 counties and over 500,000 acres of crop, pasture, and range land to address the following three …
Quantifying The Short-Term Impacts Of Cover Crops And Grazing On Soil Health Under An Integrated Crop-Livestock System In South Dakota, Vishal Seth
Electronic Theses and Dissertations
Cover crops and grazing under Integrated Crop-Livestock System (ICLS) can impact the rhizosphere nutrient cycling and may have potential to increase the long-term sustainability and economic profitability of agricultural production system. In South Dakota, crop production practices and livestock husbandry are both common which provide the opportunity for ICLS to be successful in this region. However, little is known about the impacts of the cover crops and grazing under ICLS on soil properties in this region. The present study was conducted at South Dakota State University Research Farm (44°20'34.8"N, 96°48'14.8"W), Brookings, SD, to quantify the impacts of cover crops and …
Insecticidal Seed And In-Furrow Treatment Recommendations For Soybean And Sunflower, Brady Hauswedell
Insecticidal Seed And In-Furrow Treatment Recommendations For Soybean And Sunflower, Brady Hauswedell
Electronic Theses and Dissertations
Throughout the 2016 and 2017 growing season, field research experiments were replicated across South Dakota. Many times seed treatments are used prophylactic, which is neither good for the producers or the environment. Producers will be able to reduce production costs, if they only use a seed treatment when necessary. The purpose of the first experiment was to determine the effects of seed treatments in combination with planting date and seeding rate on soybean yield. To determine the effects, two years of field data from four eastern South Dakota locations were compared. Within each year and location we compared two planting …
Evaluation Of Tillage, Crop Rotation, And Cover Crop Impacts On Corn Nitrogen Requirements In Southeastern South Dakota, Sara Louise Berg
Evaluation Of Tillage, Crop Rotation, And Cover Crop Impacts On Corn Nitrogen Requirements In Southeastern South Dakota, Sara Louise Berg
Electronic Theses and Dissertations
Nitrogen (N) is a vital factor of corn (Zea mays) production. Previous work in South Dakota has shown that there is uncertainty as to whether nitrogen requirements are the same for corn raised under no-till (NT) versus conventional till (CT) production systems. The objective of this study was to evaluate whether N requirements continue to be greater under long-term NT versus CT production systems in southeastern South Dakota, while also considering effects from cover crops and crop rotation. This was a two year study conducted at the SDSU Southeast Research Farm near Beresford, SD; it was superimposed on a long-term …
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 …
The 1970'S: A Decade Of Growth In South Dakota Irrigation, Donald Taylor
The 1970'S: A Decade Of Growth In South Dakota Irrigation, Donald Taylor
Economics Research Reports
South Dakota ranks twentieth in the nation in its irrigated acreage. Depending on how "irrigation" is defined, South Dakota has between 450,000 and 500,000 acres of irriqated land. About 375,000 acres has been developed under State-issued permits by private individuals and groups. An additional 66,450 acres comprise the Belle Fourche and Angostura Federal Irrigation Projects, although in any one year not all of this land is necessarily irrigated. About 52,300 acres of "dry draw, spreader" irrigation involves the intermittent backing up of water behind dams in small creeks for occasional irrigations by farmers and ranchers in the West River Region. …
The Economics Of Irrigated Crop Production In Eastern South Dakota, Donald Taylor, Richard C. Shane
The Economics Of Irrigated Crop Production In Eastern South Dakota, Donald Taylor, Richard C. Shane

The economics of dryland versus irrigated crop production in two of South Dakota's ·fast-irrigation-growth counties -- Brookings and Turner are examined in this paper. Special attention is given to the economic impacts on the farm economy of rising energy prices and high interest rates. The analysis is in terms of conditions experienced during the 1981 crop year and projected conditions through 1990.
Crop Budgets For Irrigated Agriculture In Central-East Central South Dakota - 1982, Richard Shane
Crop Budgets For Irrigated Agriculture In Central-East Central South Dakota - 1982, Richard Shane
Economics Research Reports
Irrigation development in all of South Dakota has received much attention in the past years. Today several major water development projects are being considered. These projects include both surface and groundwater resources. That some development, whether public or private, will take place seems to be a foregone conclusion. In order for individual crop producers to decide whether to adopt irrigation technology or not requires an evaluation of profit potential with and without irrigation on their land resource. Most potential irrigators have personal records from which to derive dryland enterprise budgets to use in profit projections. Dryland producers with no irrigation …
Irrigation Development: It's Potential Impact On South Dakota's Economy, Richard Shane, Ralph J. Brown
Irrigation Development: It's Potential Impact On South Dakota's Economy, Richard Shane, Ralph J. Brown
Economics Research Reports
Irrigation development has been and will continue to be a key issue facing the people of the state of South Dakota. As irrigated acreage increases, benefits accrue throughout the State. The irrigator's income earning potential is expanded and income variability is reduced as drought impacts on yields are ameliorated. In addition, a more stable, larger quantity of feed can be produced for livestock production. This may allm-1 for expansion in the livestock industry or less importation of feedstuffs into an area. The nonfarm economy may also benefit from irrigation development. Since irrigation requires the purchase of more inputs such as …
