The percentages of clay in the three soils producing the beets with the highest content of sugar (about 14.6 percent in each case) were as follows: In the sample from Agricultural College. Mich, (field 3), 8.86 per cent; in that from Ithaca, N. Y., 19.18 per cent, and in that from Lafayette, Ind., 22 per cent, while the soil producing the poorest beets, namely, Washington, D. C, had 21.4 percent of clay. It is evident from a study of the figures grouped in the following table that, while the texture of the soil, as shown by the mechanical analysis, undoubtedly has a direct bearing on the yield per acre, it has practically no effect on the content of sugar in the beet: Mechanical analyses of soils and data regarding the crops of sugar beets grotrn thereon. RELATIOX OF CROP TO THE CHEMICAL PROPERTIES OP THE SOIL. In considering the effect of the chemical composition of the soil upon the character and magnitude of the crop we have a problem of intricate difficulties. If we regard the soil in the light of the total plant food contained therein as indicated by treatment with hot concentrated hydrochloric acid for a considerable period of time we introduce figures which must be foreign to the problem in question. In point of fact, in order to have any accurate conception of this problem it is necessary to differentiate the amount of any given plant food consumed by a given crop from the total supply which is present. This might be illustrated by an attempt to determine how much nourishment would be given a man of average size during a day by analyzing the total nourishment in a barrel of flour from which his day's supply of bread has been ...
