Studies based on the amount of some bacteria in the vineyards depending of maintenance of the soil surface
Journal Title: Scientia Agriculturae - Year 2015, Vol 10, Issue 1
Abstract
On the basis of studies were conducted in the period 2010-2011 in the vineyard of Velika variety, which was organically grown and planted in 2004 in the village of Nayden Gerovo was found that the content of the mobile phosphorous and potassium in the soil at the end of the experiment is the greatest in those grapevine which are fertilized with manure – 8.8-10.9 mg 100g-1. In conventionally grown vines and in plantation, which are mulched with straw, the content of phosphorus is higher in the 0-30 cm layer, in comparison to that one of 30-60cm. The ammonium form of the nitrogen undergoes an identical course of formation and utilization in the layer of 0-30 cm and 30-60 cm during the period May-July to September. The number of microorganisms in the plantation with manure is the highest, followed by the vines grown with greening up in row spacing, after that is the mulching with straw and at the least is in the control. The organic matter is an important prerequisite for the activation of the biological activity in various microorganisms.
