Application of animal manures influences enzymatic activities and microbial dynamics in soils. Poultry manure (PM) and swine manures (SM) were applied at the rate of 30 t ha−1 each. The experiment was arranged in a randomized complete block design with three replicates. Soils were sampled at day 0, 14, 28, 42, 56, 70 and 84 from 0-15 cm and 15-30 cm depths. In both the PM and SM amended soils, significant increase in soil pH was observed. In PM treated soil, alkaline phosphatase significantly increased from 0.38 Mg g-1 to 4.94 Mg g-1 whereas in SM treated soil, it increased from 1.21 Mg g-1 to 4.80 Mg g-1. Acid phosphatase significantly increased from 0.42 Mg g-1 to 3.02 Mg g-1 in PM amended soil while increases from 0.11 Mg g-1 to 2.38 Mg g-1 were observed in SM amended soil. The application of PM and SM increased Total Heterotrophic Bacterial Count significantly from 1.27×104 Cfu g-1 to 8.63×107 Cfu g-1 and from 1.40×104 Cfu g1 to 8.10×107 Cfu g-1, respectively. Total Fungal Count significantly increased from 1.63×103 Cfu g-1 to 4.67×106 Cfu g-1 and from 2.00×103 Cfu g-1 to 5.67×106 Cfu g-1 in PM and SM amended soils, respectively.
