Overview
Available potassium refers to the potassium in soil that is readily absorbed and utilized by plants, serving as one of the key indicators for assessing soil potassium supply. Timely determination and understanding of the content and variations of soil available potassium play a significant role in evaluating soil fertility and guiding potassium fertilizer application. This kit provides a simple, convenient, and rapid method for detecting soil available potassium content, suitable for soil samples. The principle involves the reaction of potassium ions with sodium tetraphenylboron to form insoluble white potassium tetraphenylboron precipitate. The turbidity generated is proportional to the potassium ion concentration within a certain range, allowing the determination of soil available potassium content by measuring the turbidity at 420 nm.
