Potassium is an essential nutrient for the growth of animals and plants. It is commonly found in drinking water, soils, soft drinks and wine. Monitoring potassium content in soils is particularly important in applications such as agriculture, horticulture and greenhouses for determining the soil quality.
Potassium content is typically measured using photometry or ISE. Hanna offer a wide range of instrumentation for accurate determination of potassium concentration.
