PROCESS FOR STIMULATING ROOT GROWTH AND STABILIZING GROUNDNELY MELIORIZED UNDERBOARDS

摘要

The invention relates to a method for stimulating the root growth and stabilization of soil-technically meliorierter sub-soils by applying a chemical Meliorationsmittels. In one operation with the mechanical underfloor processing, the wetting of the surface in the primary loosening structure takes place completely or partially. In the application area, strengthening melioration agent causes fixation of the improved soil physical and hydrological properties and reduction of recompression tendency. At the same time, the instantly available nitrogen content of the plant induces a stimulation of the root growth, which is preserved in the long term by staggered plant availability of the added nitrogen compounds. The sustained effect of increased biological activity equates to the physico-chemical stabilization that diminishes with the slow degradation and release of nitrogen. The chemical melioration agent used is a combination of an unmodified urea-formaldehyde condensate with a faster plant-available nitrogen compound, in particular urea-ammonium nitrate solution.
