    Agricultural Research at the Central Substation, Highmore, South Dakota: A Progress Report

    Get PDF
    Central Substation has been serving central South Dakota for over 50 years. It was established in 1901 on land deeded to the state by Mr. and Mrs. Frank Drew in 1899. There are 117.15 acres, and the location is immediately northwest of Highmore on Highway 14. For many years the research was conducted under the watchful eye of the late Steve Sussex. He served as superintendent from 1908 to 1948. After Mr. Sussex retired, he and Mrs. Sussex continued to live at the substation. I became superintendent in 1950 and found his counsel very helpful in carrying on the research activities. Gerald Keehn had served as superintendent from 1948 to 1950. Much has been accomplished at the station since the original one-tenth-acre plots were laid out permanently in 1908. In July 1932, crop yields over a 19-year period were summarized in Experiment Station bulletin 272. Four types of crop rotations were started in 1912 and have been continued ever since. The fruits of these trials are perhaps just being realized. That is the great value of your experiment stations. They formulate recommendations from results obtained over 5 or 10 or even 40 years or more of research-not just a year or two. Extreme care must be taken to avoid errors in our results. That is why we use long-time research results and repeat each trial a number of times and at various locations. Highly trained scientists of the State Experiment Station staff help us conduct the research. We find that people of this area have a friendly feeling toward the substation and its activities. Results of the research have been brought to their attention through field days and reports in newspapers and publications. When Mr. Drew donated the Janel for the substation he said that knowledge secured from this land would serve as a basis for farming. We should keep his foresight in mind

    Soils of Clay County South Dakota

    Get PDF
    The Clay County soil survey is an inventory of the soil resources found in that area. It is designed to help answer questions such as: What soil types do I have on my farm? Do different soil types need different management practices? If so, what are the suggested practices? Are certain crops better adapted to different soil types? Do soil types have different yield potentials? Published soil surveys are made up of two parts: a map and a report. The Clay County soil map, bound in the middle of the report, shows the location and extent of the various soils in the county. Descriptions of each of the soils shown on the map and the suggested management practices for each are given in the report. Tables are included which list estimated yields of principal crops for each soil, the general agricultural rating for each soil, specific management recommendations, and suitability for irrigation

    The soil map, in the folder attached to the back cover of this bulletin, has been divided into two sections, the eastern half and the western half. These maps show the distribution of different soils that occur in the county. In the text, recommendations as to the use, management, and conservation are made in an attempt to answer the major questions of the farmers and others interested in the soils of Day County

    Renal Cell Carcinoma in a Horseshoe Kidney and Preoperative Superselective Renal Artery Embolization: A Case Report

    Get PDF
    Only rarely is renal cell carcinoma encountered in a horseshoe kidney. This is a case report on renal cell carcinoma in a horseshoe kidney, in which superselective renal artery embolization was performed preoperatively. CT and digital subtraction angiography revealed a horseshoe kidney with a 3-cm tumor in the left side. Superselective renal artery embolization of the tumor was performed as a prerequisite procedure for the organ-preserving surgery of simple enucleation. Preoperative superselective renal artery embolization can be an effective tool to facilitate organ-preserving surgery in a horseshoe kidney

    A Progress Report: Agricultural Research at the Range Field Station, South Dakota State College Experiment Station, Cottonwood, S.D.

    Get PDF
    South Dakota, west of the Missouri River, may be divided into three distinct regions. The most northerly of these is a series of benches, plateaus, and isolated buttes underlain by both sandstone and shale. These soils range from sandy loams to clays but are predominantly loamy. The most southerly region is a series of plateaus and broad benches underlain by silty, sandy, and clayey strata. These soils range from very sandy on the Nebraska border to silty and clayey at the southern tributaries of the White River. Between the two just described lies the third region. This is the region of the State represented by the Cottonwood Range Field Station. It is called the Pierre hills and is underlain by shaly strata which weather to dark clayey soils that are sticky when wet. These shaly strata do not form benches and plateaus like the younger strata to the north and south. Rather, they are reduced by weathering to a series of smooth grassy hills and ridges with convex tops. In the central region the major rivers, and the other two as well, Bow east. Stream valleys are entrenched several hundred feet and the rivers in them pursue meandering courses. Cottonwood trees flourish in the stream channels. (See more in text

    Progress in Agricultural Research at the North Central Substation

    Get PDF
    Thousands of acres of farm land in the north central part of South Dakota have their productive future tied up with the 240 acres used for experimental research at the Substation at Eureka. Established nearly 50 years ago by the state legislature, which set aside state school lands for agricultural research, the North Central Substation is the proving ground for new agricultural methods and a living record of the accumulative effects of the old. As early as 1908, rotation experiments were started which became the first historical record in the northern plains area of the effects of cropping practices on the soil. At that time, the entire surrounding country was in wheat. There were no crop rotations, since the organic matter of the soil was good and the fertility level high. Also, there was no weed problem then. Later, the Experiment Station was to be accused of scattering weeds in one of the most interesting stories to be uncovered in the development of experimental research in this area. Foreseeing the time when the fertility of the land might become dangerously lowered by the practice of continuous cropping which was being carried on at that time, the Substation set up experimental plots. These included the basic crops of rotation-cultivated crops, small grain and legumes. In this case, the legume was sweet clover. (See more in Text

    This soil survey report has been written primarily for the farmers of Jerauld County, which is located in central South Dakota. Wessington Springs, the county seat, lies almost in the center of the county and is 41 miles by highway southwest of Huron, and 112 miles by highway southeast of Pierre. The soil map in the folder attached to the back cover of this bulletin shows the distribution of different combinations or associations of the soils that occur in the county. In the text, recommendations \u27.1S to use, management, and conservation are made in an attempt to answer the major questions of the farmers and others interested in the soils of Jerauld County
