9894. Cramer, C.. 1987. Water saving 'weed' replaces chem-fallow.. The New Farm, Sept/Oct 1987, p. 28-29..
Black medic is successfully being used in Montana as a reseeding annual legume in dryland rotations. The medic is protecting the soil from erosion, improving soil structure and water-holding capacity, disrupting weed and disease cycles, and reducing saline seep. Becauce medic is a shallow-rooted legume, it is supplying the soil with added nitrogen but only drawing water from the top 2 feet of the soil profile. This moisture is replaced by snow melt. The medic can also be a profitable hay crop.

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.
