This article presents the results of field-testing of two wastes: wine lees and vinasse, from grape processing. The results demonstrated that administration of two doses of wine lees (13 and 16 t/ha), the vinasse (300-600 m3/ha) favoured the significant increase of organic matter, phosphorus and exchangeable potassium in the arable layer of soil. Application of wine lees at a dose of 13 to 26 t/ha annually ensured a significant increase grape 1.4-2.3 t/ha, or 15-25% more than the unfertilized control, which made 9.3 t/ha. Significant impact on the productivity of plants of wine lees and vinasse was at a dose of 300 to 600 m3/ha. Average growth was 0.9-1.0 t/ha or 10-11% more than the control. |
