Overview
2.1Programme description
Button Mushroom Production: Compost and Casing explains the process behind Agaricus bisporus, the white and brown mushrooms found in most supermarkets. You will follow the compost through Phase I, Phase II and Phase III, learning how raw materials, water, turning and temperature create a selective substrate. The course covers spawning, casing soil preparation and case running, then the climate steering that triggers pinning and controls the size and quality of each flush, ending with picking, grading and farm hygiene.
Button mushroom production is a highly technical, industrial process, and even experienced staff benefit from understanding why each step matters. Small deviations in compost or climate show up quickly as lower yields or disease. This course suits Agaricus growers, technicians and staff joining a commercial farm. In the final project you analyse a crop cycle, real or provided as a case, identifying how compost quality, casing and climate decisions affected yield and quality, and propose improvements reviewed by your professor.
2.2Why it matters / what need it meets
It meets a practical need: applied, up-to-date knowledge in cultivation, useful in areas such as Commercial Agaricus production, Compost and casing supply, Fresh produce packing, Agricultural technical services.
Mycology is moving fast and good practical training is still scarce. This programme gives you a structured path, taught live by people who work in the field, so you can apply what you learn with judgement and safety.
