For soil testing, take the sample in such a way that it represents the entire field, at least 500 grams of the sample must be taken.
Remove organic materials such as crop residue, dry leaves, stalks and grasses etc. from the top surface of the soil and choose samples from 8-10 different locations according to the area of the field.
Soil sampling should be done from the depth at which the root crop is taken.
Soil samples should be collected in a clean bucket or tagari etc.
