b) The straw becomes soft and bendable, and the blocks come apart easily

d) The moisture content of the compost should be between 68 and 74%.
The first stage of composting is completed when the described humidity, temperature, color, and odor are achieved.
Stage 2: Complete composting (carried out under controlled conditions) After 15-20 days of composting, the stage 2 process begins by first pasteurizing, killing bacteria and weed seeds, and removing ammonia. The compost is sent to a special chamber for an 8-hour pasteurization period at 56±60 ° C and continues for a conditioning period of up to 7 days at 45 ° C until volatile NH3 is removed from the process air. Pasteurization is a controlled, temperature-dependent process that lasts about a week.
After Il phase, the substrate is ready for the growth of mushroom mycelium.
