Corn Two Years.--Hunt says that the prosperity of the east, as a whole, would be greatly increased if the rotations of crops were so modified as to increase the corn acreage. He suggests the four rotations given in the table below, which is taken from Bulletin 116 of the Pennsylvania experiment station. The fertilizers recommended should maintain fertility. CORN IN CROP-ROTATIONS +-------+-------+-------+-------+-------------------------------------+ | 3 Yr. | 4 Yr. | 5 Yr. | 7 Yr. | | | ------+-------+-------+-------+-------------------------------------+ | | | | 1 | Corn: 6 to 10 loads of manure and 25| | | | | | pounds of phosphoric acid. | | 1 | 1 | 1 | 2 | Corn: 6 to 10 loads of manure and 25| | | | | | pounds of phosphoric acid. | | | 2 | 2 | 3 | Oats: no fertilizer. | | 2 | 3 | 3 | 4 | Wheat: 50 pounds each of phosphoric | | | | | | acid and potash. | | 3 | 4 | 4 | 5 | Clover and timothy: no fertilizer. | | | | 5 | 6 | Timothy: 25 pounds each of nitrogen,| | | | | | phosphoric acid, and potash. | | | | | 7 | Timothy: 25 pounds each of nitrogen,| | | | | | phosphoric acid, and potash. | +-------+-------+-------+-------+-------------------------------------+ The Oat Crop.--In the northern part of the corn belt the oat crop is profitable. In the southern half of Ohio and regions of like temperature the oat crop rarely pays. The heat, when the oat is in the milk stage, usually is too great. The tendency there is to eliminate this crop. Where silage is wanted, the stubble-land can be seeded directly to wheat with good results. A common practice is to seed to wheat between the shocked corn, and the wheat does poorly unless the soil is quite fertile. Two Crops of Wheat.--A common practice has been to grow two crops of wheat, seeding first in the corn stubble-land, and plowing the ground for the second wheat crop, making a smooth surface for mowing. This method ceased to pay well when wheat became low in price. It has the advantage of giving two cash crops to the rotation. Where winter wheat does not thrive in the north, it is dropped out, and the seeding to clover and grass is with the oat crop. There is the compensation of a large oat yield where the climate is too cold for a good crop of wheat. [Illustration: In the Shenandoah Valley.] The Clover and Timothy.--The timothy and clover sod is made inexpensively so far as labor is concerned. The first crop of hay is chiefly clover, and the soil is enriched by the roots and stubble, while the hay is converted into manure.
