摘要:
Maximum yields of red clover, alfalfa, and birdsfoot trefoil were obtained when 0.25 to 1.0 ppm B was added to the soil. An application of lime to raise the soil pH to 5.8–6.3 improved yields, while at pH 6.8 a decline in yield in the first and second cuts of birdsfoot trefoil was noted. There was a marked B x lime interaction on the yield of all cuts of birdsfoot trefoil and first cut of red clover, with much higher yields with high rates of lime at high rates of added B.
