Abiotic factors


 
 
Concept Explanation
 

Abiotic factors

Abiotic factors: Abiotic factors include moisture, temperature, the composition of the storage container and oxidation in certain foods.

Moisture content: The moisture content of stored grain should be sufficiently low, i.e., around 14% by weight. This does not mean that the grain should not have any moisture at all. Grains lose their germinating power if the moisture content is reduced beyond a certain limit.

Temperature: The temperature at which foodgrains are stored is an important factor because a certain temperature range is ideal for the growth of insects and microorganisms. While insects find 30° to 32°C optimum for their growth. If the storage compartment is kept cool and dry, much of the damage to the foodgrains can be averted.
