Post Bioremediation Effect on Soil Fertility using Substrate from Livestock Byproduct

Abstract

The purpose of this study was to examine data obtained from soil physicochemical properties before and after initiation of bioremediation using liquid manure as a nutrient source. Bioremediation was initiated by stimulating autochthonous microorganisms present in soil rhizosphere while remediation was determined by soil physicochemical status after nutrient amendment. Rhizomes of turmeric were planted in soil treated with liquid manure and control in a randomized complete block design (RCBD) with three replications. Data generated from soil physicochemical parameters both in the laboratory and field were analyzed before and after treatment/cultivation. The study showed that treated soil increased total nitrogen, organic matter, organic carbon, exchangeable potassium, cation exchange capacity (CEC), calcium and exchangeable phosphorus. On the other hand, it decreased soil acidity, pH and exchangeable aluminium. There were no observable differences in magnesium concentration. Soil texture had more sand and a corresponding decline in silt and clay. Findings in this study revealed that soil that benefitted from treatment option is statistically significant at 0.05 p-level.
