Phosphate absorption coefficient
WebJun 3, 2010 · In both cases, the concentration of phosphate (Pi) in soil solution is suboptimal for crop production. A first line strategy for soils with low total P content is regular amendment with small doses of P fertilizer. However, in soils with high total P content that fix most of the P, P fertilizer will equally be fixed. WebPlateau concentrations were reached after 1 h for the gel made with 0.05 wt % α-HAP (5.0 × 10 −8 mol·L −1 , i.e., 8 mol %) and after more than 12 h for the other two samples (1.5 × 10 −6 mol·L −1 ,...
