Borewell in Chennai having a Soil Test is a process by which elements (phosphorus, potassium, calcium, magnesium, sodium, sulfur, manganese, copper and zinc) are chemically removed from the soil and measured for their “plant available” content within the sample.
These analyses indicate whether lime is needed and, if so, how much to apply. Package the sample appropriately. Put the soil mixture in the sample box. Do not tape the box or put soil in a plastic bag. If you are sending several sample boxes through the mail, pack them carefully in a sturdy container. Mail samples to the Agronomic Division laboratory at the address on the back of this publication.
