Resumo: |
The use of organic wastes plays an important role in agriculture due to its potential for diminishing yield costs and minimize environmental impacts. The work was carried out to evaluate the effect of mineral fertilizer and filter cake doses on sugarcane (Saccharum officinarum L.) yield and soil chemical characteristics. The experimental was conducted in a greenhouse, in design was the casualized blocks with three replications, in a factorial outline (5x3), with five doses of filter cake (0; 9,25; 18,5; 27,75 e 35 g pot-1) and three levels of mineral fertilizer (0; 50 e 100% of the recommended dose). The results showed that cake filter addition favored soil fertility, increasing the contents of both macro and micronutrients and decreasing Al concentration. Filter cake promoted corrected soil acidity while mineral fertilizer acidified the soil. Sugarcane plants responded to filter cake application by increasing the uptake of phosphorus, potassium and copper. The use of filter cake associated with mineral fertilization is recommended in order to increase sugarcane yield while reducing costs with mineral fertilizers. |
