| Abstract |
A pot experiment was carried out in a sandy soil to study the effect of mycorrhizal inoculation and organic matter fertilization on microbial activity and nutrient release in soil. Glomus sp. Biogas residues, town-refuse compost and sludge manure were used in this work. Viable microbial counts of phosphate dissolving bacteria and dehydrogenase activity in soil were greatly enhanced by organic manuring. Mycorrhizal inoculation exhibited slight increases in these parameters. Biogas residues were superior over other organic manures. A highly positive linear correlation was found between viable microbial counts and dehydrogenase activity in control soil, biogas residues and sludge treatments. The correlation was significant at the 0.05 level, with town-refuse compost treatment.
Significant increases in the availability of mineral nitrogen and phosphorus occurred after organic manuring. On the other hand, mycorrhizal inoculation seems to have a non-significant effect on nutrient liberation, particularly in organic manure treatments
