Question

The process of covering spawned compost with a suitable material is known as
A. cropping
B. casing
C. spawning
D. composting

Answer 1

Hint:
Before we proceed into the problem, it is important to know the definitions of covering spawned compost.
The only way to force mushroom mycelia to transition from the vegetative phase to the reproductive stage is to cover the surface of the spawning compost with an appropriate material known as the casing layer.

Complete step by step answer:
Composting is the name given to the entire process. In general, composting is the process of piling substrates for a set amount of time and allowing them to undergo changes brought on by the activity of various microorganisms. The end product is a substrate that is chemically and physically distinct from the original substrate.
The nutrients, minerals, vitamins, and ions needed for healthy mushroom growth are provided by the compost. Only the mycelium of button mushrooms can grow on this compost; other moulds that are competitors cannot.
Mushrooms can obtain crucial nutrients needed for development and fructification from compost, an artificially generated growing media. In order to produce high-quality compost, flooring must be cemented.
As a result, the casing of mushroom beds or spawn run compost is a covering spawned compost. A medium lacking in nutrients is casing soil.

Option ‘B’ is correct

Note:
The purpose of casing soil is to preserve the compost's surface's moisture content and gas exchange, which promotes the mycelium's healthy growth. The casing soil's pH should be between 7.7 and 7.8, and it must be devoid of any infections or diseases. Once the compost has been covered in the fungus's white mycelium, a homogeneous layer of 3–4 cm thick casing soil is applied.
