Practical sampling process for nematodes community

The nematode community can reflect soil conditions and they are used as indicators of soil conditions in crops cultivar. For studies, it is necessary to separate nematodes from the environment in which they live their life cycle. Sampling is a process that requires knowledge of the nematodes life cycle, tools for soil sampling, sampling pattern, best sampling time, storage and care of samples. It is necessary to make a proper distribution or sample plan. When sampling it is necessary to pay attention to certain features: crop type and field history, areas planted to different varieties, type of soil, moisture of soil, soil compaction, seasonal changes of clime etc. Sampling pattern is important because of better cumulative representation of the nematode populations at the field. Sampling process have some phases which can affected on inaccuracy such as mixing soil samples, washing samples, analysing samples, taking additional sub- samples and washing and analysing sub-samples. Results inaccuracy can be partly avoided by taking a larger and higher number of samples and sub-samples.
