Biochar 4mm – 8mm 10kg.
This Biochar is a Hardwood from a sustainable source. 10kg dry weight bag which is approximately 50L.
Biochar is a fine-grained, highly porous kind of charcoal. It’s microscopic pore structure provides immense internal surface area and optimum habitat for soil microbiota. This porosity makes biochar an ideal amendment for increasing soil aeration and water retention.
Research has shown that when biochar is mixed into animal manure, compost, urine, or other nutrient-rich organic waste materials, it only takes a few minutes to reduce noxious odours. This indicates nutrient losses (mostly nitrogen, which is released as ammonia gas) from these substrates is at least partially inhibited, very quickly.
Biochar literally soaks up nitrates, phosphates, dissolved organic carbon (DOC), and other easily soluble substances during aerobic composting.
