摘要: . The tolerance of wheat plants to manganese is shown depend on the magnesium concentration in shoot tissue, such that growth a function ratio two ions Mg: Mn. This plant (Rp) and soil solution (Rs) was related by equation: ln Rp= 1.45+0.31 ln Rs. Values Rp not limiting need be determined for different crops, but we conclude corresponding values Rs can predicted using culture trials. They then used identify remedial treatments soils where toxicity occurs. In Eutric Cambisol examined, small amounts calcium carbonate decreased concentrations which could easily applied field gave appropriate wheat.
