Compost is the primary growing medium for button mushrooms, made from decomposed organic materials such as straw, chicken manure, and chalk. This nutrient-rich substrate provides ideal conditions for the growth of mushroom mycelium, ultimately resulting in a high-quality crop.

Additional information

Appearance

Color: Good compost is a dark, uniform brown color. A light, grayish color indicates insufficient fermentation or the presence of undesirable molds. A deep black color may indicate anaerobic conditions and poor fermentation.
Texture: Compost should have a compact but loose, aerated structure. It should not be in the form of silty lumps or excessively dry and crumbly. Proper compaction ensures moisture retention and prevents the surface from drying out.
Free of unrotted raw materials: Primary raw materials such as straw should be largely decomposed and should not be visible in long, distinct pieces.

The smell of compost

Absence of ammonia odor: This is the most important quality indicator. Compost should not have any strong, unpleasant ammonia odor. A faint odor similar to that of ammonium (not free ammonia) may be tolerable, but a strong odor indicates a serious problem.
Favorable odor: Good compost has an odor similar to that of damp soil, mushrooms, or a forest after a rain. This odor indicates the activity of favorable microorganisms.
Absence of sour or moldy odor: A sour (vinegar-like) or moldy (stale bread-like) odor indicates the presence of undesirable microorganisms and spoilage of the compost.

Field tests

(Optional but helpful)
Moisture test: Squeeze a handful of compost in your hand. It should feel slightly moist and a few drops of water should come out, but it should not be dripping.
PH test (using a pH meter): The pH of the finished compost should be in the range of 6.8 to 7.5.

Ammoniametry

(Industrial scale)
On large farms, ammonia meters are used to accurately measure the ammonia concentration in compost. The free ammonia concentration must fall below 20 ppm (parts per million) for the compost to be considered suitable for seeding.
