5. Mix the soil in the bucket thoroughly and properly to obtain a uniform soil mixture after collecting from all the composite cores.

One sample should consist of about 20 cores taken from the set area.The sample zones should be of similar characteristics and more or less uniform in slope direction, vegetation, management practices and cultivated area and crops. It is recommended that the cores be taken from the area in a zig zag pattern as shown below:

  1. Different tools such as a soil sampling tube,soil auger,or spade may be used to take soil samples.Do not use galvanized,soft steel or brass equipment if trace metal analyses are desired.  Clean all tools between sampling.
