Book Description
Excerpt from The Value of Crop Rotations for Soil and Water Conservation The data show the yield of corn for 1943 was practically the same for mulch and no mulch. For the other 2 years there was a marked decline in the corn yields where the straw mulch was used, so that for the 3-year period there was a difference of bushels in favor of the no mulch areas.

Book Description
Excerpt from Crop Rotation and Soil Cultivation: A Paper Read by J. H. Grisdale, B. Agr., Director, Dominion Experimental Farms, Before the Standing Committee of the Senate on Agriculture and Forestry, 1911 The supply of plant food in a soil is very commonly supposed to be the measure of its crop producing powers. Such, however, is not exactly the case. Even the moat barren soils, so far as plant food is concerned, may in a few years he made to produce most excellent creps provided the other conditions of plant growth be right. Any soil to which humus can be added at not too great expense will shortly be found to yield profitable crop returns.

Book Description
Excerpt from Crop Rotations and Soil Management for the Prairie Provinces It will be seen that the average yield of wheat from 1912 to 1926 inclusive has been 2509 bushels per acre which is a very satisfactory yield. However, during this period of 15 years, the yield has varied all the way from 17 bushels per acre in 1919 to 60-2 bushels per acre in 1915. The yields during the latter years of the period seem to be quite as large as those secured when the rotation was commenced.

Book Description
Excerpt from Review and Discussion of Literature Pertinent to Crop Rotations for Erodible Soils In the United States speculative farming has been the general practice, and all possible e ort has been made to continue producing cash crops to the exclusion of grasses, legumes, and other soil-improv ing crops. Continuous production of cotton in the South, corn in the Ohio and upper Mississippi Valleys, and wheat in the central and northern Great Plains and the Palouse country of Oregon, Washing ton, and Idaho has resulted in an enormous loss of valuable soil through erosion (fig. There are no more new lands to move to when the fields become unproductive, and the speculative farming days are ending. Gra dually7 the speculators are being forced out and farmers who love the land and have a real desire to maintain it for future generations are taking possession. The wave of speculative farming, naturally, was from east to west; and the older agriculture of the Eastern States, as would be expected, apparently has a higher per centage of nonspeculative farmers.

Book Description
Excerpt from Crop Rotation Experiments in the Ohio Valley (1925-1936) For centuries men have recommended the practice of alter nating crops systematically. Early agriculturists noted that the practice led to increased yields. Such increases have been found to be due in part to better control Of weeds, insects, and diseases and to better utilization of plant nutrients. It is known, too, that certain rotations will aid in maintaining the supply Of organic matter and nitrogen in the soil and will lessen erosion. However, not all systems of crop rotation are equally desirable. Some rotations may actually bring about soil depletion almost as rapidly as continuous cropping with the same crop, whereas other systems may maintain satisfactory yields with minimum applications Of fertilizer.
