The Beet Sugar Industry In The United States In 1920 PDF Download

Excerpt from The Beet-Sugar Industry in the United States Sugar beets are no harder upon the soil than are the other crops generally grown; all require the same plant foods in slightly differ ent proportions. If not supplied with the material removed by the various crops or if the plant foods in the soil are not made available by the application of humus and by proper cultivation, the soil be comes worn and infertile, and the yields of all crops, including sugar beets, are greatly reduced. Quality of the soil - Soils vary widely in their original qualities, both physical and chemical. All agricultural soils are supplied in varying proportions with the necessary plant foods for crop pro duction. Soils that have plant food present in great abundance may be said to be rich. They are not fertile, however, unless these plant foods are in soluble form or unless they are rendered soluble as rapidly as the various materials are required by the plant in the process of growth. The quality of the soil from the standpoint of fertility may be greatly improved by proper cultivation, cr0p rota tion, and the addition of humus, as well as by the application of lime or other material that will improve its physical condition. In Special cases special treatments, such as subsoiling and drainage, are needed to make the soil highly productive.
