This is a great natural product to improve your soil. The mix of biochar, composted chicken manure and lime is the ideal combination for Auckland clay soils. The biochar and chicken manure compost increase the organic matter and fertility of the soil, while the lime improves the soil structure and reduces the acidity of the soil. For established garden beds: Apply 2 cup fills per m2 as a top dressing. For new gardens, mix into the soil as you dig approx. 10 cup fills per m2 prior to planting. We use this in our vegetable garden with great results. Available in refillable buckets.
