| Abstract: | The potassium bearing volcanic rock somewhere which consists of the ores including zeolite,glassy feldspar,biotite and glass matrix is rich in the ore reserve and is easy to mine.Its average grade of K 2O is 3 31%.Through experiment,its content of quick acting potassium has been achieved from medium to extremely high level of K supplying potentiality.So it can be used directly in agriculture.It has the best effect especially in Karst red soil zone. |
