Air pollution is influenced by wind-aided particulate suspension, open-air waste burning, and fossil fuel combustion. The pollutants from these sources eventually deposit on ambient surfaces. Atmospheric wet deposition into Lagos Lagoon may be significant additions to the nutrient levels of the eutrophic lagoon. Precipitation was monitored at three stations in the Lagos Lagoon basin from May ...

Effect of Calcium and Phosphorus Levels on the Performance ...

In most soils, phosphorus (P) fertilizer application promote soil acidity and inconsistent/no P response. Hence, the application of organic and inorganic fertilizer as soil amendments should be tested. The effects of Organo-Mineral Fertilizer (OMF) on maize growth response and soil properties in some P-unresponsive soils and a responsive soil were investigated.

INTRODUCTION. Phosphorus is an essential micronutrient element which has been observed to limit crop productivity (Odiete et al., 2005; Attwel and Adams, 1993).In soils, it exists in two main forms: organic and inorganic forms (Busman et al., 2002).Each form is a continuum of many P compounds existing in equilibrium with each other and ranging from solution P to very insoluble or unavailable ...
