BioMix is a manufactured topsoil that is highly resistant to erosion. BioMix ingredients are Fibergro (short paper fiber), compost, and a mineral base soil - most of which we source from residual streams that would otherwise go to waste. Most cost effective is when an end user can provide a suitable base soil (mineral sand or a low quality loam), then we provide the Fibergro and compost, recipe blend recommendations, and technical assistance to mix the blend onsite.
BioMix is easily created by mixing using conventional construction equipment. Casella Organics' soils specialists provide a simple bucket to bucket mixing recipe and are on-site to provide oversight and to help maximize efficiency.
