Is potassium nitrate good for plants?
Potassium nitrate, also known as nitrate of potash, is being used primarily on high value crops such as celery tomatoes, potatoes, leafy vegetables and a few fruit crops. It has a low salt index and is a source of soluble nitrogen and potassium. Potassium nitrate also has a neutral effect on pH. Production costs have limited general use for most agronomic field crops.
