The Influence of Applied Phosphorus, Manure, or Lime on Uptake of Lead from Soil
1976
Zimdahl, R. L. | Foster, J. M.
Studies of the uptake of lead from soil by corn (Zea mays L.) have shown that soil applications of phosphorus [Ca(H₂PO₄)₂·H₂O] decrease uptake, but translocation was affected and at higher lead levels. Lead uptake decreased when cow manure was added to attain a total organic content of 6%, but there was no effect of additional manure. Liming did not have a consistent effect on uptake, but lead translocation appeared to decrease with liming. The addition of phosphorus was not an agronomically feasible way to reduce the effects of lead contamination, but additions of manure and lime offered promise of reducing lead uptake.
