Collecting Screening Soil Samples 6.2013
· • Soil gathering can take place daysahead of the sample processing. However, it is preferable to not let the sample dry out. • In general, only about 1 in every 30 samples screened will yield a phage that infects Mycobacterium smegmatis. There are some general guidelines that may be followed to increase these odds.

A soil sample is assigned to one of the twelve soil texture classes according to the values for the proportions of sand, silt, and clay, which are located along each of the three axes. The eight subclasses in the sand and loamy sand groups provide refinement that in some cases may be greater than can be consistently determined by field techniques.

· the soil sample. Soil texture is directly related to the percolation rate of a soil in the size of air spaces and surface area of the soil particles. For example, sand is the largest of the soil particles; therefore it has the largest surface area of the soil particles. Percolation is usually quick in sandy soils.
