Decomposition rate of hydrogen decomposition bacteria
Answers
In addition to the composition of organic matter, nature and abundance of microorganisms in soil, the extent of C, N, P and K., moisture content of the soil and its temperature, PH, aeration, C: N ratio of plant residues and presence/absence of inhibitory substances (e.g. tannins) etc. are some of the major factors which influence the rate of organic matter decomposition.
As soon as plant and animal residues are added to the soil, there is a rapid increase in the activity of microorganisms. These are not true soil organisms, but they continue their activity by taking part in the decomposition of organic matter and thereby release of plant nutrients in the soil. Bacteria are the most abundant organisms playing important role in the decomposition of organic matter. Majority of bacteria involved in decomposition of organic matter are heterotrophs and autotrophs are least in proportion which are not directly involved in organic matter decomposition. Actinomycetes and fungi are also found to play important role in the decomposition of organic matter. Soil algae may contribute a small amount of organic matter through their biomass but they do not have any active role in organic matter decomposition.
Answer:
Decomposition is the process by which dead organic substances are broken down into simpler organic or inorganic matter such as carbon dioxide, water, simple sugars and mineral salts.
