Weed-controlling mulching composition

摘要

To provide a mulching technique which is excellent in weatherability and waterproofness, exerts a high anti-erosion effect on inclined lands, is efficacious in inhibiting the growth of weeds in agricultural and non-agricultural lands and preventing outflow of soil and formation of muddy water accompanying rainfall and makes it possible to control soil temperature. A weed-controlling material includes as the main component a slurry comprising from 3 to 30% by weight of magnesia cement having a chemical composition comprising lightly baked magnesia and being non-stoichiometric and from 97 to 30% by weight of water.
