CheKine™ Micro Soil Available Potassium Content Assay Kit - 96 T/96 S

Readily available potassium refers to the potassium in the soil that is easily absorbed and utilized by plants. It is one of the important indicators characterizing the soil potassium supply status. Timely measurement and understanding of the content and changes of readily available potassium in the soil are crucial for evaluating the fertility of cultivated land and guiding the application of potassium fertilizers. CheKine™ Micro Soil Available Potassium Content Assay Kit provides a simple, convenient, and rapid method for detecting the readily available potassium content in soil samples. The principle of this assay is that potassium ions react with sodium tetraphenylborate to form an insoluble white precipitate of potassium tetraphenylborate. The turbidity produced is proportional to the potassium ion concentration within a certain range, and the content of readily available potassium in the soil is determined by measuring the turbidity at 420 nm.
