Build up of organic material in soil is under which of the following conditions to
The correct option is C Aerobic conditions, >25oC temperature
Presence of oxygen is necessary for the growth of a microorganism in the organic matter. Under anaerobic conditions most of fungi and actinomycetes growth suppressed only a few bacteria grow in anaerobic organic decomposition. The rate of temperature for maximum growth of the microorganism is 30° to 40°'. The adequate moisture is required for the proper decomposition of organic matter. The rate of decomposition of organic matter is maximum in the neutral soils than the acidic soil. C: N ratio has a great influence on the decomposition. Narrow C: N ratio of soil and organic water is required for rapid and better decomposition of organic matter.
So, the correct answer is ' Aerobic conditions, > 25°C temperature '
