dc.descriptionSoil and root parameters that influence nutrient uptake were evaluated in this study of comparing the effectiveness of phosphate fertilizers in an acid soil. North Carolina rock phosphate (RP), partially acidulated Togo rock phosphate (PA), monocalcium phosphate (MCP), and diammonium phosphate (DAP) were applied to limed (pH 5,6) or unlimed (pH4,6) soil samples. Eighteen days later, transplanted corn (Zea mays L.) seedlings were grown in pots for 12 days. Soluble phosphates, DAP and MCP, were the most efficient fertilizers for increasing corn dry matter on limed pots; in absernce of limestone, the best yield was obained with DAP because it decreased soil solution A1. Phosphorus in the soil solution (Pli) was lower on limed than on unlimed samples, but resin-exchangeable P was not affected by liming. MCP gave the highest increase of Pil on unlimed samples whereas DAP did it in presence of liming. Root dry matter and root length were greater on limed than on unlimed pots for all sources of P, except for DAP, where the soil acidity had no detrimental effect on these parameters.pt_BR
