Excerpt from Publications From the Department of Agriculture and Biological Chemistry, the Pennsylvania State College, State College, Pa, Vol. 2: 1931-1935The effect of a high concentration of lime in the soil is to render soil pot ash and potash applied in fertilizers more insoluble. Care should be taken, therefore, to avoid using lime where it is not necessary, and to avoid, as far as possible, those treatments, such as ap plying excess quantities of nitrogen containing materials, which increase the availability of the lime in the soil.In addition to rendering soil potash insoluble, our results show that a high concentration of lime tends to inter fere with the direct absorption of this material by the plant, especially in a dry season. Under these conditions we find that the dry matter of the cured plants contains about 8 per cent of lime and about 2 per cent of pot ash. This is not desirable, the large amount of calcium is not helpful to the burn, while the low content of potash is even more undesirable from the standpoint of burning quality. The plants also contain excessive quan tities of nitrogen, which 15 harmful to the burning quality.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
