速效钾是土壤中易被植物吸收利用的钾素，是表征土壤钾素供应状况的重要指标之一。及时测定和了解土壤速效钾的含量及其变化，对耕地地力评价及对指导钾肥的施用有着重要作用。本试剂盒提供了一种简单、方便、快速的土壤速效钾含量检测方法，适用于土壤样本。其原理是钾离子与四苯硼钠作用，形成不溶于水的白色四苯硼钾沉淀，产生的浊度在一定范围内与钾离子浓度成正比，通过检测其在 420 nm 处的浊度来测定土壤速效钾的含量。
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.
