硅酸盐细菌有很强的解钾能力，同时还有解磷和固氮能力。将其菌剂与土壤混合制成每克干土含10亿左右细胞的生物钾肥，用于大豆试验，结果表明生物钾肥可使土壤中有效氮、磷、钾含量提高，促进大豆植株对养分的吸收，使其干物质积累量增加，根瘤数量提高。
Silicate bacteria have a strong ability to dissolve potassium, as well as phosphorus and nitrogen fixation. The fungicide and soil were mixed to make bio-potash fertilizer containing about 1 billion cells per gram of dry soil for soybeans test. The results showed that bio-potash fertilizer can increase the content of available nitrogen, phosphorus and potassium in the soil and promote the nutrition of soybean plant Absorption, to increase the accumulation of dry matter, nodulation increased.
