Phosphorus fixation of citrate- and water-soluble phosphates in chernozem and pseudogley low in available phosphorus


, : Phosphorus fixation of citrate- and water-soluble phosphates in chernozem and pseudogley low in available phosphorus. Arhiv za Poljoprivredne Nauke 27(97): 97-108

When water-soluble P (mono- and di-ammonium phosphates) and a citrate-soluble form (dicalcium phosphate) were applied individually or as mixtures, P fixation increased with increasing P up to the highest rate added (20 mg P2O5/100 g soil). In pseudogley increasing duration of contact between fertilizer and the soil increased the P fixation, the maximum occurring after 2-4 weeks.
