Abstract
The phosphorus and potassium are two fundamental soil nutrients in grape production. Both of them, in most cases are incorporated in soil during autumn-winter period. In the last two decade, the tools and equipment for working in vineyard has a strong improvement. One of the new tools for grape production from this developing is the special tool for deep fertilizer application i.e. fertilizer applicator. The evident problem for fertilizer applicator is permanent trails of tractor and work in the same depth during long time. In this application mode, the concentration of phosphorus and potassium become toxic. The access of rootstock roots in this small area, are very limited because the concentration of nutrients is very high. The consequence is low usability of these nutrients. This research gives some verified scientific aspects of long time application of fertilizer applicator in grape production and their negative effect.
