Nws muaj qhov kub thiab txias siab tiv taus, bibulous tus nqi tsawg, cov yam ntxwv ntawm cov tshuaj ua haujlwm tau ruaj khov. Muaj peev xwm tiv taus cov kua qaub, alkali thiab lwm yam kuab tshuaj organic, thiab tuaj yeem tiv taus hauv cov txheej txheem kev hloov pauv ntawm qhov kub thiab txias. Nws lub luag haujlwm tseem ceeb yog txhawm rau nce cov pa roj lossis cov ntsiab lus faib ua kua, txhawb thiab tiv thaiv kev siv tsis yog kev ua haujlwm siab ntawm cov catalyst.
