Organic matter as truly the key to soil fertility and health. Free-living nematodes play important roles in soil nutrient cycling. Nematode excretion may have contributed soluble nitrogen in soil. Nematodes have more C: N ratio and lower N content as compare with the bacteria C: N ratio they consume. Growth efficiency of nematodes is smaller than those of the bacteria. Nitrogen mineralization, abundance of many free-living nematodes populations in soil mainly bacterivorous, omnivorous, and predatory nematodes. | The role of free living nematode population in the organic matter recycling
