Although the decomposition processes of plant residues in rice field soil has been documented, the structure and dynamics of the microbial communities involved are poorly understood. Understanding plant litter decomposition in broad-leaved forests is important because it influences the geochemical cycles of nutrients and represents a vital link in the global carbon cycle. Process of Decomposition by Microorganisms • Within a very short time period microorganisms can breakdown and digest a large amount of soft tissue, resulting in a large production of gas and ‘decomposition fluid’ • As decomposition proceeds, the skin begins to darken to various shades of green and brown. Thus, preferences for soil conditions and litter quality were explored to understand their niche partitioning. Aerobic composting is a dynamic process in which the work is done by the combined activities of a wide succession of mixed bacteria, actinomycetes, fungi, and other biological populations. Bacteria is even useful in the degradation of oil spills. Bacteria play an important role in litter decomposition, especially late in the decomposition process, when they become abundant. Factors That Influence the Decomposition Rate of Organic Matter in the Soil. Healthy soil is living soil, teeming with living things from microscopic bacteria to earthworms. The fungi which Although the decomposition processes of plant residues in rice field soil has been documented, the structure and dynamics of the microbial communities involved are poorly understood. The bacteria and fungi play a very significant role in plant litter decomposition and humus formation. Plant litter decomposition is not a purely chemical or physical process, it is basically a biological one resulting from the diverse activities of microorganisms, protozoa and various other soil organisms like insects and worms. leaf litter decomposition; reciprocal transplant; bacteria; fungi; elevation gradient; Microbial communities are the engines of decomposition (), a fundamental process regulating the carbon cycle.In ecosystems, microbial decomposition converts detritus into CO 2 and releases nutrients for plant growth. Although some studies tend to confirm the dominance of fungi in litter decomposition in situ (Schneider et al. Soil microorganisms are diverse, although they share functions during the decomposition of organic matter.
