Organic Biochar Fertilizer

Your soil has been through a lot. Chemical fertilisers, compaction, erosion — it's taken a hammering. This is how you start giving it back. Our organic biochar fertiliser is plain biochar that's been charged with organic raised sheep manure slurry, creating a living, nutrient-dense amendment that works with your soil biology rather than against it. Chemical fertilisers flush through and are gone in a season. This stays. The biochar structure locks in nutrients and microbial activity for 20 to 30 years, meaning every bag you put down is a long-term investment in the health of your land — not just a quick fix.
