For a few hours the compost is cool, moist, rich and open, and every competitor on the farm would like it. Wash the floor and the mixing platform before the compost arrives. Keep the room shut against flies. Use clean tools, wash hands, and let nobody walk in from the composting yard in the same footwear.
Work fast and finish in one session, because spawn left open for hours collects spores. ICAR-DMR documents chemical treatments for rooms and tools, and current label approval must be checked before anything is used.
