Abstract: This study assessed the usefulness of poultry and swine manures in the improvement of soil properties, microbial counts and dehydrogenase activities. A randomized complete block design was applied with three replicates consisting of poultry and swine manures as treatments applied at the rate (30 t ha−1) on each of the two experimental plots. Soil samples obtained from depths 0-15 cm and 15-30 cm at week 0, 2, 4, 6, 8, 10 and 12 for dehydrogenase and microbial densities using standard procedures. The pH (H20) slightly increased from 4.08 to 5.60 following manure application. At 0-15 cm soil, poultry manure increased pH by 25% soil while swine manure increases by 21%. Potential dehydrogenase recorded highest amount of production 7.09 Mg g-1 at 6 weeks of decomposition treated with swine manure at 15-30 cm soil depth. Bacterial counts increased from 1.27 x104 Cfu g-1 to 6.00 x107 Cfu g-1 in soil treated with poultry manure whereas soil amended with swine manure increased from 1.50 x104 Cfu g-1 to 7.10 x107 Cfu g-1. The results revealed that swine manure enhanced dehydrogenase production and microbial diversities than poultry manure.
