Relation of the Depth to Which the Soil Is Wet at Seeding Time to the Yield of Spring Wheat on the Great Plains (Classic Reprint)


Book Description

Excerpt from Relation of the Depth to Which the Soil Is Wet at Seeding Time to the Yield of Spring Wheat on the Great Plains Under the limited precipitation of the Great Plains, the initial water content of the soil, which can be approximated by the depth to which the soil is wet, is a strong determinant of the yield that Will be produced.

Growing Winter Wheat on the Great Plains


Book Description

"Limited rainfall is the controlling factor in crop production in the Great Plains. The average yields of a series of years can be foretold from the records of past years; but because the rainfall is fluctuating in amount and uncertain in distribution, the yields of a simple year can not be foretold with any certainty. The chances of success are, however, much better when the soil is wet to a considerable depth at seeding time than they are when the soil contains little or no available water at that time. The relation between the amount of water in the soil at seeding time and the yield is much closer with winter wheat than with other crops. This crop should, therefore, be seeded on the best-prepared land and that in which the greatest amount of water is stored. Except in the southern section, the response of winter wheat to summer tillage is greater than that of any other crop. Summer-tilled land should be seeded to winter wheat wherever this crop can be grown. The growth of corn is one of the best preparations for winter wheat, especially north of Kansas. With increase in the length of season and the time between harvest and seeding, there is an increase in the value of early preparation for winter wheat. In the northern section the crop can be replaced with spring wheat without serious loss. In the central section winter wheat has a greater advantage over spring wheat and can not be replaced by the latter without serious loss. In the southern section, winter wheat is less certain and less productive than farther north and can not be replaced by spring wheat. It is, however, profitably raised under favorable conditions of oil, season, and preparation. In this section particularly it should be recognized that the chances of producing a crop are low when it is seeded on land that does not contain water enough in storage to wet the soil to a depth of 3 feet."--Page 2




Variability of Wheat Yields in the Great Plains (Classic Reprint)


Book Description

Excerpt from Variability of Wheat Yields in the Great Plains Yield variability decreased in the 4 Northern Plains states-montana, North Dakota, South Dakota, and Wyoming-due to both improved weather and technology. In western Kansas, western Nebraska, and Oklahoma Panhandle, and in most counties of eastern Colorado, an increase in wheat seeded on cultivated summe r fallow and on irrigated acreage helped to make wheat yields more stable in 1940-62 than in the earlier period.

The Great Plains and the Supply of Wheat (Classic Reprint)


Book Description

Excerpt from The Great Plains and the Supply of Wheat The Great Plains has no commonly accepted fixed boundary. In general the mountains on the west, the 20-inch rainfall line on the east, the Canadian boundary on the north, and the southern edge of the high plains escarpment on the south, are taken to be the limits of the Great Plains. This region, without embracing any entire State, includes parts of 10 States commonly designated as the Great Plains States are: Montana, North Dakota, South Dakota, wyoming, Nebraska, Colorado, Kansas, New Mexico, Oklahoma, and Texas. For the purposes of this report an area termed the high-risk area has been delineated, indicating approximately the part of the Great Plains in which wheat growing is accompanied by the greatest climatic hazards (fig. Irrigated areas insofar as practicable have been excluded. This area has been delineated primarily on the basis of the judgment of a number of agricultural workers in the Great Plains, supported by actuarial data from the Federal crop Insurance Corporation. It should be regarded as a preliminary delineation, subject to later refinement. In particular, it should be pointed out that the degree of risk is by no means the same ln all parts of this area. Or convenience in the use of statistics, the area boundaries follow county lines. It will be noted that a boundary between the areas of spring-wheat and Winter-wheat production has been drawn. This indicates only that one predominates over the other. A wide belt is found in which both are grown. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
