    This study focused on assessing nitrogen mineralization in sandy soil amended with different types of poultry manure. The pH, NO3- and NH4+ levels in the soil were assessed at different soil moisture conditions over a short laboratory aerobic- incubation period. The objectives of the study were: (1) To assess the pH levels of the manure-amended soil at different soil moisture conditions during the aerobic incubation period, (2) To assess the NO3- levels of the manure-amended soil at different soil moisture conditions during the aerobic incubation period, (3) To assess the NH4+ levels of the manure-amended soil at different soil moisture conditions during the aerobic incubation period.
