One of the most important challenges to continuously maximize crop production on limited areas of agricultural land is to maintain or enhance soil fertility. Organic fertilizer application is needed to replace nutrient removed by crop from the fields in order to restore crop production potential of a soil. But application of organic fertilizer alone insufficiently increases crop yield per area because the nutrient content of organic fertilizer is unbalanced. A trial was conducted in the Lubumbashi region to investigate the combined effects of mineral fertilizer and chicken manure application on the balance of minerals and maize yield. Three mineral fertilizer doses (0 kg NPK+0 kg urea, 150 kg NPK+100 kg urea, 300 kg NPK+200 kg urea) and four chicken manure quantities (0, 1.75, 3.5, 7 t haG1) have been tried. The combination of these factors gave a total of 12 treatments. According to obtained results nitrogen and phosphorus content before maize sowing is higher than those obtained after flowering. The present work confirms that integrated application of chicken manure and mineral fertilizers is more effective in increasing nutrient availability and maize performance than mineral or organic fertilizer applied alone. In contrast, applied doses of chicken manure have not improved soil nutriment balance sheet. Combined with the low dose of mineral fertilizers (150 kg NPK+100 kg urea), the amount of 7 t haG1 of chicken manure resulted a better yield increase, which corresponds to 46% compared to the control, of which 16% only are due to mineral fertilizer application.
