Southeast South Dakota Experiment Farm Annual Progress Report, 1999, Agricultural Experiment Station

Agricultural Experiment Station and Research Farm Annual Reports

Crop production was moderate to poor this season. Our climate was mild in terms of temperatures but precipitation was quite erratic. In fact the growing season was both extremely wet and dry. During the first half of the growing season we received 5 inches of rain above normal, and the last half was 4.5 inches below normal. Some fields in our area were too wet to plant or drowned out after planting. Strong wind and hail caused moderate to severe crop damage on July 2. Our last significant precipitation occurred on July 20. After that the rains stopped completely and …

Sampling Weed Spatial Variability On A Fieldwide Scale, Sharon A. Clay, G. Jason Lems, Frank Forcella, Michael M. Ellsbury, C. Gregg Carlson, David E. Clay

Agronomy, Horticulture and Plant Science Faculty Publications

Site-specific weed management recommendations require knowledge of weed species, density, and location in the field. This study compared several sampling techniques to estimate weed density and distribution in two 65-ha no-till Zea mays–Glycine max rotation fields in eastern South Dakota. The most common weeds (Setaria viridis, Setaria glauca, Cirsium arvense, Ambrosia artemisiifolia, and Polygonum pensylvanicum) were counted by species in 0.1-m2 areas on a 15- by 30-m (1,352 points in each field) or 30- by 30-m (676 points in each field) grid pattern, and points were georeferenced and data spatially analyzed. Using different sampling approaches, weed populations were estimated by …

Influence Of Deleterious Rhizobacteria On Leafy Spurge (Euphorbia Esula) Roots, Mark A. Brinkman, Sharon A. Clay, Robert J. Kremer

Agronomy, Horticulture and Plant Science Faculty Publications

Rhizobacteria have been shown to be phytotoxic to leafy spurge in laboratory assays. This field study investigated the influence of two strains of Pseudomonas fluorescens [Trevisan, (Migula)], deleterious rhizobacteria (DRB), on root weight, root bud number, and root carbohydrate content of leafy spurge at three sites located in northeast and north-central South Dakota. Soils were inoculated with 2 g of starch-based granules containing no bacteria or starch granules containing 108colony-forming units (cfu)/g of either bacterial strain LS102 (Montana origin) or LS174 (South Dakota origin). Bacterial strains were detected on root samples from treated areas. Root weight and root carbohydrate content …

Precision Farming Protocols: Part 1. Grid Distance And Soil Nutrient Impact On The Reproducibility Of Spatial Variability Measurements, Jiyul Chang, David E. Clay, C. Greg Carlson, Douglas D. Malo, Sharon A. Clay, John Lee, Mike Ellsbury

Agronomy, Horticulture and Plant Science Faculty Publications

To determine temporal changes in soil nutrient status, reproducible results must be obtained at each time step. The objective of this paper was to determine the impact of grid distance on the reproducibility of spatial variability measurements. Soil samples from the 0 to 15 cm depth were collected from a 30 by 30 m grid in May 1995 in a 65 ha notill corn (Zea mays L.) field. Each bulk sample contained 15 individual cores, collected at sample points located every 11.4 cm along a transect that transversed 3 corn rows (57 cm). At each sampling point latitude, longitude, elevation, …

Historical Evolution Of Crop Systems In Eastern South Dakota: Economic Influences, Linda Dumke, Thomas L. Dobbs

Economics Research Reports

Cropping systems in the United States and throughout much of the world have moved toward shorter and less diverse rotations during the last half of the twentieth century. However, as we approach the new millennium, there is growing concern about the ecological sustainability of monocultures and such narrow rotations as the com-soybean rotation. Problems of pest control, crop disease, groundwater contamination from chemical pesticides and fertilizers, and soil erosion are proving to be very difficult when crop rotation systems lack diversity. "Silver bullet" technologies sometimes buy time, but without diversity, new ecological problems soon replace the problem just "solved" with …

Agricultural Land Values In South Dakota: A Comparison Of Methods And Findings From Two Surveys: 1995-1999, Larry Janssen

Economics Research Reports

This report provides comparative findings from two South Dakota farmland market value surveys (SDSU and SDASS) for the 1995 - 1999 period. The annual SDSU farmland market survey is a key informant mail survey of agricultural appraisers, lenders, and extension educators. The annual SDASS county-level farmland survey results are based on nearly 3300 telephone survey responses from a random sample of farmers and ranchers. This report also includes considerable documentation of methods used to generate land value estimates at the regional and statewide level from available data in both surveys. The results and discussion sections include comparisons of: (1) relative …

Organic Price Premiums For Northern Great Plains And Upper Midwest Crops: 1995 To 1998, Thomas L. Dobbs, Jamie L. Pourier

Economics Pamphlet Series

Price premiums for organic crops have drawn the attention of increasing numbers of farmers in the Northern Great Plains and Upper Midwest in recent years. Falling prices for crops grown with "conventional" farming methods have caused an increasing number of farmers to explore the possibilities of switching to organic methods and obtaining organic certification. One indication of this interest has been the relatively high attendance at meetings of organic and sustainable farming associations in 1998 and 1999. As part of the sustainable agriculture research program in the Economics Department at South Dakota State University (SDSU), we have been comparing "organic" …

Influence Of Crop Rotation, Tillage, And Management Inputs On Weed Seed Production, George O. Kegode, Frank Forcella, Sharon Clay

Agronomy, Horticulture and Plant Science Faculty Publications

Approaches to crop production that successfully reduce weed seed production can benefit farming systems by reducing management inputs and costs. A 5-yr rotation study was conducted in order to determine the effects that interactions between crop rotation, tillage, and amount of herbicide and fertilizer (management inputs) have on annual grass and broad-leaved weed seed production and fecundity. There were 10 crop rotation and tillage system combinations and three levels of management inputs (high, medium, and low). Green and yellow foxtail were the major weed species, and together they yielded between 76 and 93% of collected weed seeds. From 1990 to …

Planning Prices And Livestock Budgets For Farm Management Programs, Burton Pflueger

SDSU Extension Circulars

The budgets in this publication are based on approved farming practices and nutritionally balanced rations. Feed ingredients are priced on their comparative feed values. Com is used as the base for feed grain and other grains are priced based on their relative feed value to com. Alfalfa hay is used as the base for roughage. All roughage and succulents are priced as a percent of alfalfa hay. The livestock husbandman who uses the least-cost rations should not see significant changes in profitability by interchanging feed ingredients.
