Potassium Test Kit for Soil
Potassium is present in tissues responsible for the growth of plants (primary and secondary meristems). It plays an important role in how much water is absorbed by the roots and in the regulation of cellular activity. In addition, potassium makes plants more resistant to diseases and yields a positive effect on the color and fragrance in flowers. Potassium deficiency is a frequent problem in calcareous soils.
The HANNA test kit determines potassium in soil via a turbidimetric method. Potassium is precipitated in a basic environment with sodium tetraphenylborate. The developed turbidity is proportional to potassium concentration.
