	abstract = {Under rangeland conditions most grasses should not<sup>.</sup>be seeded deeper than 2 cm.  Harsh environmental conditions in the surface soil often prevent successful seedling establishment.  Army and Hudspeth (1960) and Hudspeth and Taylor (1961) reported that under field conditions in the southern Great Plains sufficient moisture for seedling emergence of grasses planted at the customary shallow depths could not be maintained on bare surface soil except under extremely favorable weather conditions.  The average annual precipitation in that area ranges from 36 to 58 cm.  Environmental modification, particularly of the moisture and temperature, is imperative to insure greater success in grass establishment.  Artificial and natural mulches and land-forming procedures offer increased possibilities for obtaining seedling establishment under difficult environmental conditions.},
