Soils of Day County South Dakota

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

Soils of Clay County South Dakota

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

Soils of Jerauld County South Dakota

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

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

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

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

Soils Survey of Spink County South Dakota

This soil survey report with its accompanying map presents information about the soils, crops, and agriculture of Spink County. It also deals briefly with such related topics as topography and cultural features. This soil survey is designed to meet the needs of a wide variety of readers. The following paragraphs indicate the sections of interest to persons concerned with specific tracts of land, to those concerned with the county as a whole, and to students and teachers of soil science and related agricultural subjects

Reconnaissance Soil Survey of Potter County

Potter County covers an area of 568,320 acres in north central South Dakota. The topography is gently sloping in the central part with a belt of hilly land along the east border and the steep, dissected bluffs of the Missouri River trench along the west border of the county. Elevations above sea level range from 1,900 to 2,000 feet on the upland to 1,600 feet on the Missouri River flood plain. Materials from which the soils have developed include glacial deposits which occur in all parts of the county except on the Missouri River bluff where shale is exposed. Soils of the county have been classified into 35 mapping units, each of which is described with regard to composition, distribution, and agricultural use. Principal problems of management are discussed and estimated yields of important crops are given for each soil, along with its potential irrigability
