Why do We Use Sulphuric Acid on Potatoes?
The application of sulphuric acid to growing potato plants is carried out for the following reasons: • Killing off the shoots (haulms) of the potatoes makes mechanical lifting of the tubers at harvest very much easier. • Killing off the haulms also makes the plant move resources to the tubers so giving them a growth burst prior to harvesting. The use of this chemical is strictly controlled, with stringent conditions being placed on those who use it.
