A threefold increase in grazing capacity was achieved in a five-year range improvement program involving the seeding of adapted clovers, phosphorus fertilization, and grazing management on over 500 acres. Grazing records and quadrat harvests demonstrate the marked success of the improvement methods.

The above progress report is based on Research Project Nos. 1526, 1194, and 1317.

The range improvement studies reported in this article were conducted with the assistance of the Franceschi Ranch and the Chamberlain Ranch near Lincoln, Placer County.
