INNOVATIVE CELLULOSE ADSORBER TO INCREASE TREE PROTECTION AGAINST HARMFUL EFFECTS OF ROAD DE-ICING SALT

The study examines the adsorption capacity of compressed cellulose fibres in cylindrical pellets intended for protecting plants and soils from road salt. The innovative adsorbers use short-fibre cellulose waste, which is unsuitable for recycling and is compressed under pressure ranging from 0.1 to 12.0 MPa. Various cylindrical adsorbers were tested and characterised using the Evaporation surface coefficient (ESC). The most efficient absorber with a diameter of 19 mm and a length of 26 mm at a humidity of 6.76% adsorbed brine to 87%. Cellulose adsorbers outperformed previously described Salix viminalis willow chips in de-icing salt capture efficiency (Spisak et al. 2020)

IMPREGNATED WILLOW WOOD CHIPS (SALIX VIMINALIS L.): A NOVEL SOIL AMENDMENT FOR ENHANCING SOIL QUALITY

This study introduces a novel method of treating willow chips (Salix viminalis L.) by impregnating them with a solution of conventional mineral fertilizers. Modified willow wood chips have the potential to utilize as an innovative soil amendment and offer benefits for agriculture, horticulture and forestry to improve soil water retention capacity, soil fertility and structure. Experimental results indicate the feasibility of developing a product with nitrogen (N) levels from a minimum of 2%, phosphorus (P) levels exceeding 0.5%, potassium (K) levels exceeding 1.5%, and an organic matter content over 90% of the dry weight
