Synopsis

Synopsis

Rock phosphate, at high rates, compared favorably with concentrated superphosphate. Sweet clover utilized rock phosphate more efficient) than other legumes when lime was also applied, but was very inefficient in the absence of lime. Six hundred pounds per acre of P2O3 from rock, supplemented with 60 pounds from concentrated superphosphate applied the first year, resulted in more total forage during 5 years than did 120 pounds per acre of PiOs from concentrated super applied annually.
