Potassium nitrite Potassium nitrite Potassium nitrite (distinct from potassium nitrate) is the inorganic compound with the chemical formula . It is an ionic salt of potassium ions K and nitrite ions NO, which forms a white or slightly yellow, hygroscopic crystalline powder that is soluble in water. It is a strong oxidizer and may accelerate the combustion of other materials. Like other nitrite salts such as sodium nitrite, potassium nitrite is toxic if swallowed, and laboratory tests suggest that it may be mutagenic or teratogenic. Gloves and safety glasses are usually used when handling potassium nitrite. Nitrite is present at trace levels
Potassium polyacrylate with less water and fewer inputs. As a soil amendment, potassium polyacrylate can improve the soil water holding capacity. Potassium polyacrylate Potassium polyacrylate is a potassium salt of polyacrylic acid with the chemical formula [−CH−CH(COK)−] As a type of superabsorbent polymer, it can absorb hundreds times its original weight in purified water. Different from sodium polyacrylate, potassium polyacrylate can be used as water retaining agent in agriculture and won't cause soil salinization. As a type of superabsorbent polymer for plants (Ag-SAP), potassium polyacrylate can increase moisture availability to plants. It mixes with soil to increase the soil’s capacity for holding
