Forage production on improved dry-land pastures fertilized with nitrogen and phosphorus was increased tenfold over untreated pasture during the mid-winter period of feed shortage, in a recent study with sheep at the Hopland Field Station.

Donald T. Torell, Assistant Specialist in Animal Husbandry, University of California, Hop-land; W. E. Moon, Senior Laboratory Technician, University of California, Davis; and Raymond A. Evans, Junior Specialist in Agronomy, University of California, Berkeley, cooperated in the studies reported here.

The above progress report is based on Research Project No. 1194.
