The Use of Technical Lignin for the Formation of Grass Cover

Summary/Abstract: During the last 30 years an active destruction of the coast, beaches and protective sand – hills as well degradation of as the coastal sand dunes have occured. Up to now technologies, which stop wind erosion in Lithuania, were based on planting trees and bush – fences. For the creation of the technology, which protects soil erosion, waste of natural origin, technical lignin and its surface strengthened by polymer, was chosen. Evaluating the use of technical lignin for the formation of grass cover three kinds of plant seeds, technical lignin, waste of wood industry and polymers made in the Latvia National Wood Chemical Institute were used. A laboratory experiment was made in June 2003 in the Public Seeds and Grain Klaip_da Municipality subdivision laboratories where seed viability and germination energy were set. A field experiment was made in July 2004 in the Botanical Garden of Klaipeda University. Two months after sowing grass cover formation on the slope was evaluated. In a laboratory research the influence of modified lignin by polymer upon seed germination was identified. Having researched the material I can state that polymers do not harm plants, it is important to choose right concentrations. Having big polymer concentrations most of the seeds did not sprout.
