Abstract

Seven grass species--desert wheatgrass (Agropyron desertorum), streambank wheatgrass (Agropyron riparium), cheatgrass (Bromus tectorum), basin wildrye (Elymus cirtereus), Sandberg's bluegrass (Poa sandbergii), bottlebrush squirreltail (Sitanion hystrix), and needle-and-thread grass (Stipa comata)--were harvested to a 1/2-inch (1.2-cm) stubble height periodically between mid-March and December in most years from 1962 through 1968 at the Saylor Creek Experimental Range in southern Idaho. These samples were analyzed for N, P, S, Ca, Mg, K, Na, Zn, Mn, Cu, and Fe. Certain digestibility fractions (NDF, NDF-ash, DCW, DCW-ash free, and TDDM) were also determined on these samples. In addition, estimates of the soil chemical status, soil moisture contents over depth and time, forage yields, and moisture contents over time, effects of ammonium nitrate fertilization on forage yields and mineral composition, and animal grazing responses to cheatgrass range are included.
