Ela knows first-hand how central compost is to his organic farm—and all organic agriculture. Department of Agriculture (USDA) compost rules could dramatically change the meaning of organic compost for farmers.
Organic mushroom farming involves growing mushrooms using organic substrates like compostedmanure, straw, or sawdust. This method focuses on maintaining the natural environment, promoting biodiversity, and protecting soil health while producing high-quality mushrooms.
Compost: Compost improves and adds nourishment to the soil. For composting systems, nutrients (like nitrogen) can be added in the form of green materials (grass clippings, kitchen scraps), and carbon (in the form of dry leaves, and straw) that can balance the nitrogen. We might suggest using both compost and fertilizer.
Organic fertilizers such as manure, compost , and other organic amendments are valuable sources of nitrogen. Ammonium nitrogen can be lost quickly through ammonia volatilization if manure or compost is not incorporated into the soil shortly after application.
Packaged poop can take hundreds of years to break down, even in bags deemed compostable or biodegradable; certifications that are based on commercial composting conditions, not landfills—but US industrial composting facilities don’t accept pet waste.

Nitrogen helps with greenery, and potassium helps with plants’ stalks and straws Why fertilisers?
And mushrooms of all kinds sprout as they feast on crop waste, coffee grounds and horse manure.

By ‘lack of humus’ he is referring to the increasing trend, even then, to dispense with returning organic matter to the soil, for example, in the form of composted farmyard manure, that was made possible by the development of synthetic fertilisers.
