Foundations for Farm Buildings

Foundations for Farm Buildings

Date: 1941
Creator: Miller, Thomas A. H. & Molander, Edward G.
Description: This bulletin discusses different ways of constructing the foundations of farm buildings. "The following general recommendations point out common errors and are intended to assist farmers to provide suitable foundations for ordinary farm structures except where unusual soil conditions are found. The foundation of a farm building may consist of (1) continuous walls, (2) a series of piers either built in place or precast, (3) a combination of walls and piers, (4) a concrete slab laid on the ground, (5) wood posts, or (6) wood sills. The essential features necessary for the successful use of the various types are discussed under the above headings; also the thickness of walls and dimensions of piers for medium-sized structures other than heavy storages are suggested. Requirements for cellar walls are given on pages 18-21. It is necessary that foundation footings be made wide enough to support the structure on the kind of soil to be built on. The characteristics and bearing power of various soils are given on p. 3. The general method of calculating the weight on footings is given on pages 38-44. It can be used where buildings are heavy or are of a different character from those described under Types ...

Improving Range Conditions for Wartime Livestock Production

Improving Range Conditions for Wartime Livestock Production

Date: 1942
Creator: Renner, Frederic Gordon, 1897- & Johnson, E. A.
Description: "The improvement of range lands to meet the demands for increased livestock production for war purposes is highly important. To bring about the greatest improvement with the least expense it is necessary to know what kinds of range lands will best respond to improvement measures. This bulletin discusses range conditions and describes that characteristics of soil and forage by which the rancher may determine which of his lands are in need of improvement." -- p. i

Ponds for Wildlife

Ponds for Wildlife

Date: 1941
Creator: Allan, Philip Farley, 1909- & Davis, Cecil N.
Description: "The first purpose of this bulletin is to show how farmers and ranchers may protect their ponds from sedimentation, soil erosion, and water loss through the use of vegetation suitable as food and shelter for wildlife; the second is to give some information on the management of wildlife in farm ponds. Unless otherwise stated, the information contained in this bulletin pertains to the water area, or pond proper, and the pond area, or the land immediately adjacent to the pond and ordinarily contained within a fence." -- p. ii

Stock-Water Developments: Wells, Springs, and Ponds

Stock-Water Developments: Wells, Springs, and Ponds

Date: 1940
Creator: Hamilton, C. L. (Clifford Leslie), 1904- & Jepson, Hans G.
Description: "The need for effective utilization of grazing areas and the scarcity of stock water have led to unprecedented activity in the development of water supplies during the last few years as a part of conservation practices in range and pasture areas. Economical construction, planned distribution, and adequacy of stock-watering centers are essential to profitable grazing enterprises. Inadequate coordination of stock-water developments with necessary conservation practices and the improper location or construction of these facilities have made many water supplies unsatisfactory. This bulletin deals with the requirements and development of stock-water supplies suitable for grazing areas." -- p. ii

Stubble-Mulch Farming for Soil Defense

Stubble-Mulch Farming for Soil Defense

Date: 1942
Creator: Carter, L. S. (Logan Sampson), 1906- & McDole, G. R.
Description: "Stubble-mulch farming, spectacular in its recent spread across the West, has sound scientific support. In one form or another, it has been demonstrating its advantages on experimental plots and in isolated field trials for many years. It is a practice that furthers the highest crop and livestock production compatible with the principle of soil security. It is a simple but effective method that will help us to avoid in the present emergency the disastrous aftermaths of the plow-up program of the 1920's. Materials for mulching are at hand -- products of the land itself -- waiting to be used for the retention of crop-making moisture and soil. Equipment can be bought on the market, or it can be rigged up by the farmer himself. Stubble-mulch farming can be fitted into a general conservation system -- applied to grain fields, row-crop land, and strip-croppered areas. It is flexible and economical, requires less mule power or machine power." -- p. ii

Strip Cropping for War Production

Strip Cropping for War Production

Date: 1943
Creator: Tower, Harold E. & Gardner, Harry H.
Description: "In the nation's effort to produce adequate quantities of all agricultural products to meet the war needs of the United Nations, conservation assumes added importance. Advancements in the management of croplands to conserve soil and moisture, which have come about in recent years as a result of experimentation and the experiences of many farmers, show that conservation increases crop yields. Strip cropping is one of the conservation practices. In its various forms and patterns, it is applicable to a large area of the United States. With the farmer rests the major responsibility of obtaining conservation on the land. Each farmer should examine for himself the need of strip cropping his cultivated land and in doing so should find the information contained in this bulletin helpful. The kinds of strip cropping, the factors influencing their use, methods of application, value in conserving soil and moisture, and the adaptation of strip cropping to the northeastern and north-central, the southeastern and western Gulf, the Great Plains, and the far Western States are discussed." -- p. ii

Small Irrigation Pumping Plants

Small Irrigation Pumping Plants

Date: 1940
Creator: Rohwer, Carl & Lewis, M. R. (Mortimer Reed), 1886-
Description: "Throughout the United States are many farms, parts or all of which could be irrigated by pumping from either ponds or streams or farm wells. This bulletin is intended to furnish owners or operators of such farms with information that will give them some indication of initial and operating costs and enable them to determine whether soil and water suitable for irrigation are available and what kind of irrigation plant and equipment will be most satisfactory for their purpose. Having examined these factors, a farmer can decide whether irrigation is likely to be profitable on his farm." -- p. i
