METHODS OF SOIL TREATMENT. Three methods of soil treatment were practiced during 1911 and 1912, after plowing under the green-manure crop in 1911, on fields M-I and M-II, as shown in figure 3. Field M-I is divided into 19 plats. Plats 1 to 14, inclusive, are one-fourth of an acre and plats 15 to 19, inclusive, are one-sixth of an acre in size. Field M-II â .con- tains 6| acres, not divided into plats. The three methods are described as follows: First method.âThe first method was a continuation of the treatment applied in 1911. Rye was planted again in the fall of 1911 and was plowed under as green manure in June, 1912. Each season after the rye was plowed under the land was left fallow during the summer and given frequent cultivations with the disk and harrow. This method was applied on plats 1 to 12, inclusive, on field M-I and to all of field M-II. Plats 1, 2, and a part of plat 3 in field M-I were subsoiled in June, 1911. Plats 7, 8, and 9 in field M-I were planted to corn in July, 1911, but the growth was very small and irregular, and no crop was Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illust
