SILICON-CONTAINING GROUND GLASS POWDER PARTICLES TO IMPROVE PLANT GROWTH

摘要

Disclosed is a method of improving plant growth and / or for providing plant available silicon to a plant or plant growth medium, comprising applying to the plant or plant growth medium silicon-containing ground glass powder particles having a silica content of at least 50 wt% and a sodium oxide content of at least 2 wt%, wherein at least 90 wt% of the particles have a particle size of less than 100.0 mm; and wherein said ground glass powder particles may be obtained by (a) providing silicon-containing glass having a silica content of at least 50 wt% and a sodium oxide concentration of at least 2 wt%; and (b) milling the silicon-containing glass to produce silicon-containing glass powder particles such that at least 90 wt% of the particles have a particle size of less than 100.0 mm.
