Water storage and alfalfa yields were influenced more by a bench's favorable location for snow collection than by size of the contributing area. Water storage overwinter averaged 1.4 inches on the slope and ranged from 4.8 to 9.1 inches on the benches. Alfalfa production averaged 1.50 tons per acre on the slope and ranged from 3.20 to 1.28 ton per acre on the benches. asoil awater aÁgua aConservação aSolo aConservation1 aWILLIS, W.
