4921. Oien, David. no date. Black medic information packet.. Timeless Seeds, RR 3 Box 461, Conrad, MT 59425.
This packet is sent to growers who purchase seed. The seeding rate is recommended at 8-10 lb/ac, planted 1/2" deep into a firm seedbed. Field trials have indicated successful medic establishment with barley, oats, spring wheat, and flax as nurse crops, but a second year of medic growth is then necessary for adequate seed production. On-going experiments in Montana (Jim Sims, MSU) are examining several rotations: medic-cereal, sweetclover-cereal, fallow-ceral, and continuous cereal, with different nitrogen rates. Results indicate that the green manures used 1-3" more soil moisture than the other treatments. Wheat yields after medic and sweetclover (25 bu/ac) were significantly higher than all other treatments. An herbicide screening tested a number of alfalfa herbicides on black medic. Poast, Fusilade, Treflan, and Kerb did not injure medic, while paraquat, Pursuit, and 2,4-DB ester caused minor injury. Solicam provided the best overall weed control with little injury to the medic.
9933. DeVault, G.. 1985. Sweet wheat.. The New Farm, May/June 1985, p.20-22..
In Gilford, Montana, where the average annual rainfall is 11.7", most farmers use summer fallow. But one farmer, Levi Hansen, does it in a non-traditional way. He seeds yellow sweetclover right along with the spring wheat. The wheat comes up before the clover. When the wheat is cut in the fall, the clover overwinters and comes on strong in spring. By May 15th, Hanson plows the clover in and cultivates during the summer as a normal fallow. He credits the sweetclover with helping keep yields up by increasing organic matter, tilth and water-holding capacity of his soil. He also estimates that the summer fallow produces an additional 60 lbs of nitrogen as crop residues break down.
