These papers study the deposition of nitrogen transport under the influences of void ratio in the study area, the transport process were examined thoroughly thorough development of mathematical modelling compared with physiochemical investigation for model validation. This was carried out to find the rate of nitrogen concentration in the study environment, the alarming rate of microbial growth from the investigation is a seriously concern causing hundred of ill health in the study location. The application of this modelling techniques generated detailed sources of nitrogen deposition at different depth and time. The developed model from the graphical representation shows that nitrogen deposition are influenced by the variation of void ratio, some location experienced exponential and vacillation determined from the derived model simulation values, high growth rate sources from micronutrient has be examined thus stratum where high concentration are deposited has been observed. The study is imperative because it has express sources of nitrogen thoroughly. Finally, it has predicted the rate of nitrogen concentration under the influences of predominated void ratio in the study area.
