Soil Sampling, Processing, and Storage

Soil is a natural element that presents unique characteristics, and soil analysis has been the most used technique for diagnosing soil fertility. The organisms that inhabit the soil, such as protists and funghi can be used as bioindicators and can be used to assess environmental changes in a specific area. Soil sampling has been considered a strong tool used to infer about protist populations or communities in the environment. Considering that soil sampling is the basis for the rational, sustainable, and economical use of soils, here we present the key points for carrying out the correct soil sampling, processing, and storage, with emphasis on the sampling process for analysis of soil protists.
