Potassium oxide hydroxide. It is deliquescent and will absorb water from the atmosphere, initiating this vigorous reaction. The chemical formula KO (or simply 'K') is used in several industrial contexts: the N-P-K numbers for fertilizers, in cement formulas, and in glassmaking formulas. Potassium oxide is often not used directly in these products, but the amount of potassium is reported in terms of the KO equivalent for whatever type of potash was used, such as potassium carbonate. For example, potassium oxide is about 83% potassium by weight, while potassium chloride is only 52%. Potassium chloride provides less potassium than an equal amount of
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
