The aim of the present study was to develop a
strategy to solubilize low-grade rock phosphate (RP) from
Purulia and Udaipur through organic acids loaded nanoclay
polymer composites (NCPC) and see their effectiveness as
source of P. An incubation experiment was conducted
under laboratory condition to study the release pattern of P
in an Alfisol from Jharkhand amended with various RPs
treated with organic acid loaded NCPC for 90 days. The
RPs were applied at a dose of 0, 50 and 100 mg P kg-1
soil, along with the organic acid loaded NCPC having
10 % clay which was applied at a dose of 0, 20 and 40 mg
organic acid kg-1 soil. The incubation experiment showed
a positive impact of the organic acids in their ability to
release P from all the RP sources, and oxalic acid performed
better over citric acid in solubilizing P from RPs.
The two indigenous RPs maintained almost comparable
available P in soil throughout the period of incubation.
With increase in levels of P application, there was an
increase in the amount of release of P from both the RPs.
Similarly, with the increase in levels of organic acid both
Udaipur and Purulia RPs showed increase in the available
P in soil. This study demonstrated that availability of P
from low-grade indigenous RP could be improved with the
interventions of organic acid loaded NCPC which could be
used as P-fertilizer and reduce the dependence on commercial
fertilizers like DAP.
