Abstract EN
An incubation experiment was conducted at laboratories of department of soil sciences and water resources, College of Agricultural, University of Basrah, to study hydrolysis of different sources of polyphosphate i.
e.
pyrophosphate (PP), tripolyphosphate (TPP) and trimetaphosphate (TMP) as compared to that of orthophosphate (OP) at 10°, 20° and 30°C in sandy loam and clay soils.
Twenty gm of soil samples treated with polyphosphate sources at rate of 250 mg p kg-1 soil were incubated at 10°, 20° and 30°C for 28 days.
Set of the samples was withdrawn each 7 days and inorganic p (Pi) was determined.
The results showed that the Pi released from OP source was higher than those released by polyphosphate sources.
Amount of pi released from all sources increased with increasing incubation temperature from 10° to 30°C but Increasing chain length of polyphosphate compounds decreased hydrolysis rate of the compound.
Hydrolysis rate was as follow: (OP > PP > TPP > TMP), However, as incubation time increased difference among sources decreased.
Increasing incubation period from 7 to 28 days increased pi released from polyphosphate but decreased pi of orthophosphate treatment at all incubation temperatures.
