某地含钾火山岩储量大，易开采，主要矿石为沸石、透长石、黑云母以及玻璃质等，平均含氧化钾３３１％．通过初步实验，速效钾含量达到了供钾潜力的中～极高水平，可直接农用，代替部分化肥，在喀斯特红土地区，效果更加显著
Some of the potash-rich volcanic rock reserves, easy to mine, the main ore for zeolite, feldspar, biotite and vitreous, with an average of 3 31% of potassium oxide. Through the preliminary experiment, the available potassium reached the medium ~ high level of potential for potassium supply, which could be directly used in agriculture instead of some fertilizers. In Karst laterite area, the effect was more significant
