Effect of Phosphate Rock Addition on Soil Organic Matter

O. O. Adesanwo^*, Adetunji M. T, S. Diatta

The fertilizer treatments consisted of four rates of Ogun phosphate rock (0, 30, 60 and 90 kg P ha-1) and triple super-phosphate at 40 kg P ha-1. Legume treatment consisted of Mucuna and cowpea and were planted as pre-rice crop. Soil samples were collected and analyzed for organic carbon. Four pellets of Ogun phosphorites labeled OG1, OG2, OG3 and ...
