The gabbro dacite blend as soil remineralizer

The present study aimed to evaluate the ability of a mixture gabbro powder and dacite promote plant growth, provide nutrients alter soil chemical characteristics. Two experiments were conducted under different field conditions, in which black oat beans added with increasing doses (0 10 t ha-1) rock blend. grain yield (beans), dry matter production (oats) nutritional status crops evaluated. At end experiments, samples collected subjected analysis. application rocks resulted an increase bean productivity corresponding 440 kg ha-1 at dose 7 relation control. blend also overall improvement most commonly fertility parameters used, although this was more evident only for phosphorus, copper, zinc nutrients. In addition, foliar contents potassium, zinc, manganese Therefore, material obtained by dacite, proportion tested, can be considered multi-nutrient source agronomic viability.
