AbstractMulching with plastic film, cinders, or juniper slash; deep furrowing; and fallowing increased penetration and retention of soil moisture, delayed soil surface crusting, and lowered seeding-zone temperatures in tests at five different pinyon-juniper range locations. Responses of seven forage species to these practices varied. The combination of plastic film mulching, deep furrowing, cinder mulching, and fallowing uniformly had resulted in greater soil moisture, more seedlings, and better early growth than other combinations. Plants under juniper slash had a longer growing season and were protected from excessive grazing by rabbits, with no evidence of toxic effects from the juniper. Cinder mulch increased seedling emergence and establishement, but in one year appeared to be toxic to the planted species. Deep furrowing generally had no advantage over surface drilling. Fallowing benefited pubescent wheatgrass and fourwing saltbush at a cold-moist pinyon-juniper site. The number of seedlings emerging gave little indication of the plant stand several years later.
