Explanation:
Temperature influences the gaseous composition of the soil air. High temperature enhances the gaseous exchange between the soil air and the atmosphere. High temperature also increases the microbial respiration and releases more CO2 in the soil air.

Answer:
The Soil air contains a number of gases. Out of which oxygen, carbon-dioxide, nitrogen, and water vapour are the most important. The composition of Soil air is more or less similar to that of the atmospheric air except the content of carbon dioxide which is several times higher. The soil fauna and flora consume oxygen and gives out carbon dioxide. Organic matter addition and cropping increases the level of Carbon dioxide in the soil. Carbon dioxide in soil air constantly moves from the soil pores into atmosphere and vice-versa. The nitrogen content in soil air is almost the same as in atmosphere.
