Show CORN AND ALFALFA . BEST DAIRY CROPS Bureau of Dairy Industry Uses Six-Year Rotation. (Prepared by the United States Department of Agriculture.) Corn, alfalfa, and pasture grass have proved to be the most profitable crops grown on the dairy experiment farm operated at Beltsville, ild., by the United Slates Department of Agriculture. Ag-riculture. The bureau of dairy industry indus-try uses a six-year rotation, three years alfalfa and three years corn. The pasture is comparatively permanent perma-nent and does not enter into the rotation ro-tation except at intervals. T. E. Woodward, in outlining tile rotation, says: "In changing from corn to alfalfa the ground is manured in the fall after the corn Is removed for silage. The land is then plowed and left in the rough to allow pulverization pulver-ization by freezing. The alfalfa is sown about the first of April and pro duces two small cuttings t lie first year. "In changing from alfalfa to corn the first cutting of alfalfa is removed the latter part of May, the ground Is plowed, and corn is planted for silage. Manure is applied for each crop ot corn except the one following the al falfa, and in summer, when it cannot be used on the corn or alfalfa, it is placed on the pastures. Lime is applied ap-plied every six years previous to sowing sow-ing the alfalfa." A mixture of six pounds of orchard grass, four of timothy, three of red-top, red-top, four of bluegrass, four of red clover, and two of alsike, sowed about April 1 on land that has been fall plowed and manured, provides pasturp about June. If the first crop of newly sown alfalfa is weedy it is made into bay, but instead of giving it barn space i: is stacked In the pasture, which is fenced so cows can eat it when pastures are short and dry. |
