Back to Earth Cotton Burr Blend consists of Composted Cotton Burrs, Composted Shredded Hardwood (1” minus), Composted Feedstock (alfalfa, sorghum, etc).  Similar analysis to Composted Cotton Burrs.  Wood pieces break down slower allowing for a more sustainable clay busting material and providing more structure for sandy soils.  Wood acts as a slow release for nitrogen.  Soil is able to pull from three raw stocks rather than one.  Feedstock and burrs break down quickly to add valuable organic matter.  Microbial activity is extremely high.
