Photograph of Widney Farm. Upland alfalfa for soil management. Earl Judge (right) discusses the advantage of alfalfa on upland for soil building and cover. Mr. Widney uses alfalfa in his conservation crop rotation. This was seeded in the fall of 1952. For a nurse crop, ½ bushel of wheat per acre cross-drilled in wide-spaced rows (every other row drilled). Wheat realized 20 bushels per acre. The utilization of alfalfa has been a spring hay crop, seed crop in the summer, and fall pasture. He has another planting of alfalfa to be in a 3-year rotation. He has been a soil conservation district cooperator since 1948. OK-279-10.
