Notes:
Agropyron desertorum (Fisch.) Schult.] were highest on C subsoil plots 4 yr out of 5 observed, and Russian wildrye [RWR, Psathyrostchys juncea (Fisch.) Nevshi] were highest on C subsoil plots 3 yr out of 4 observed. In contrast, 2 yr of spring wheat (Triticum aestivum L.) seed yields (824 kg ha-1 avg.) were 20 to 50% larger on A subsoil plots than on C subsoil, with B yields intermediate. Forage grass yields on north sideslopes of C subsoil plots averaged 1370 and 1040 kg ha-1 for CWG and RWR, about 20 to 60% greater than yields on other positions and subsoils. The largest spring wheat yields, 1068 kg ha-1, occurred on north sideslope positions of A subsoil plots. Sandy loam subsoils can enhance forage grass yields in rolling lands, while spring wheat yields can be increased by subsoils with greater water-holding capacity.
