The soil in Longting’s vineyard is 60-80cm of brown loam covered on erosion sandstone. At the beginning of the construction of the vineyard, engraftment ditch was digged with 80cm deep and 80cm wide, and 120 tons of sheep manure and 5 tons of volcanic rock powder per hectare were applied to restore structure and life to the soil. Before plantation, biodynamic spray 500 has been applied to improve the soil fertility to encourage root development. Benefiting from sod cultivation in the vineyard, soil organic matters has been increasing, and pH is 7.6, that ensuring the optimum growth of vines. At the meanwhile, sod cultivation absorbs excess water, to enable the grape to ripen well with richness in sugar.
