What is the nutrient value of GroCo?
All of the nutrients found in biosolids are also found in GroCo compost, although at smaller concentrations because of the blending with sawdust. It may be necessary to add fertilizer, especially after the first growing season. GroCo compost provides organic material, or carbon, to soils and improves the physical properties of sandy or clayey soils, just like any other organic compost ammendment.
