COHESIVE SOIL PLUGS FOR USE IN PLANT PRODUCTION

摘要

This invention relates to novel formulations for cohesive soil plugs used in plant nurseries. More particularly, this invention pertains to novel compositions for forming soil plugs for use in plant propagation that resist disintegration when the soil plugs containing germinating seedlings a re relocated from small growth containers to larger growth containers. An adhesive soil mixture comprising: (a) growing medium; and (b) a binder containing one or more of bentonite and cellulose alkyl ether.
