Influence of Liming Rate on Phosphorus Leaching from a Peat-Sand Medium
Influence of Liming Rate on Phosphorus Leaching from a Peat-Sand Medium
and
Page Range: 74 – 76
Leaching of phosphorus (P) from a peat-sand medium was measured at 3 liming rates. Leaching of P from superphosphate was reduced only at the highest rate of hydrated lime, 2.65 kg/m3 (4.5 lb/yd3), which resulted in pH 6.6. Each rate of lime reduced P leaching from the slightly soluble dicalcium phosphate. Further investigation of sparingly soluble P sources for amending soilless media is suggested.
