Potassium Nitrate

A fully soluble powdered and chloride-free fertiliser containing nitrogen and potassium. Potassium and Nitrogen are the two most important minerals for plant growth. Nitrogen is particularly important for green plants and growth, and potassium is especially important for fruiting and flowering.  It's recommended for vegetables, fruits, flowers, turf, vines and ornamentals grown in soil and soilless culture. It's also popular for hydroponic gardening, and its greenhouse grade makes it suitable for application via irrigation systems like fertigation and for foliar sprays. Potassium nitrate is also popular as a stump remover; see the product page for more information about stump removal.
