This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1913 edition. Excerpt: ...corresponding plats are shown graphically. 64 T. LY'I'1 LETON LYoN AND JAMES A. BIZZELL Experiments in 1912 The plats used in 1911 were planted in 1912 to the same kinds of crops that were grown on them in the previous year. It was thought that this might give a cumulative effect of the crop on the soil. As before, the middle sections of the plats were not planted. In one respect the plats were different from those used in 1910 and 1911, in which cases the entire plats had been planted to some crop in the preceding years. The middle sections had therefore been fallowed for two years. As a result of the fallow of the previous year the nitrates in the middle sections were much higher in spring than those in the planted sections, except in the mulched maize plats where the difierence was not great. The arrangement of the plats and their treatment, as given below, difiered only in time of planting and harvesting from that of 1911: Plat Crop and soil treatment 2201, 2209, 2401, 2409...........
