Organic Booster is aerobically composted, locally sourced poultry manure. It offers all of the benefits and none of the risks of boosting your soil with fresh chicken manure the best natural fertiliser to make your garden grow. Organic Booster is different to most other chicken manure products on the market because it is aerobically composted. Aerobic composting involves actively turning it over to oxygenate it before processing it into easy to use pellets. Aerobic composting kills pathogens and supports healthy levels of beneficial micro-organisms in your soil.
