The Effects Of Poultry Manure On Phosphorous Solubility Of Rocks Phosphate
Journal Title: International Research Journal of Applied and Basic Sciences - Year 2015, Vol 9, Issue 11
Abstract
Organic fertilizer are able to enhances the solubility of many nutrient elements in soil. Hence for evaluating the effects of poultry manure on phosphorous solubility in two kinds of rock phosphate an experiment was carried out in a factorial design with three replication in lab condition . Treatment includes: 1- Moisture at two levels (F.C and S.P), 2- Poultry manure ratio to Rock phosphate at three levels (20, 40 and 60 percent), 3-incubation times (15,30 and 60 days). At final the phosphorous solubility of treatments was measured in water and Citrate. The results showed that citrate soluble phosphate had not significant variation with respect to times but water soluble phosphate had a negative trend with times. With increasing poultry manure levels, Water soluble phosphate increased but citrate soluble phosphate declined. Moisture had not significant effects on water soluble phosphate but citrate soluble phosphate showed a negative trend with increasing moisture. Water soluble phosphate was the most in F.C moisture content, 60 percent poultry manure and 15 days incubation times in concentrated rock phosphate but citrate soluble phosphate was maximum in S.P moisture levels, 20 percent poultry manure at 15 day incubation in concentrated rock phosphate.
