Potassium Nitrate for Stronger and Healthier Plants

Potassium nitrate is virtually free of chloride. When the chloride concentration in the soil solution increases,
plants take up chloride on the account of essential anionic nutrients, especially nitrate. This, of course, hinders plant growth. When chloride quantities go higher, toxic effects are caused, that may lead to loss of yields and may even cause plant death. Potassium nitrate is virtually free of detrimental chloride, and the nitrate in potassium nitrate counteracts the chloride's harmful effect.

Potassium nitrate is non-toxic to roots. Unlike ammonium, the nitrate-nitrogen in potassium nitrate does not destroy plant roots at elevated soil temperatures.

Potassium nitrate improves tolerance towards frost. The potassium in potassium nitrate helps to build thicker cell walls, and increases the concentration of electrolytes inside the cell, thus increasing the plant’s frost resistance.

Potassium nitrate increases the resistance of the plant towards diseases. The potassium in potassium nitrate eliminates the accumulation of short-chained carbohydrates and non-protein nitrogen, which may serve as substrates for invading bacteria, fungi, nematodes and viruses.

Potassium nitrate enhances drought tolerance. Potassium nitrate encourages establishment and branching of a root system that better absorbs water from the soil.
