Bio-potassium fertilizer is a new type of stimulation agent, namely silicate fungicide. The production practice in some areas over the past few years has shown that the application of biological potassium fertilizer must pay attention to the key application techniques under certain environmental conditions, in order to exert a good yield increase effect.
First, pay attention to soil conditions. The application of biological potassium fertilizer on loamy soil rich in organic matter, alkali nitrogen and available phosphorus is good. The soil that is too thin and the soil with poor water retention and fertility is not suitable for application. The soil available potassium content is less than 100 g/m3. Potassium soil application has the best effect on yield increase.
Second, we must pay attention to water conservancy conditions. In irrigated land with irrigation conditions, the application of biological potassium fertilizer increased the yield significantly.
Third, it should be applied preferentially to the upper and lower sorghum, and to the potassium crop.
4. When storing and using biological potassium fertilizer, it should not be exposed to sunlight. The seed dressing should be carried out indoors or in the shed.
5. Biological potassium fertilizer can be used in combination with fertilizers such as urea, nitric acid, ammonium sulfate, potassium sulfate and potassium chloride. However, it should be mixed and used, it should not be stored, and should not be mixed with alkaline substances such as grass ash.
Sixth, we must pay attention to early application. According to the field test results, the application effect was better when the soil was applied, seed dressing, rooting and transplanting. If it is top dressing, it should be chased early in the seedling stage; on the contrary, the later the application, the worse the effect.
Seven, to apply near, that is, to apply the biological potassium fertilizer around the roots, the closer the better.
Eight, pay attention to the application of uniformity, in order to facilitate the full play of the microbial crops.
Efficient application of biological potassium fertilizer should pay attention
The main role of potash is to improve the quality of agricultural products and the resistance of crops. There are fewer varieties of potash, and the main ones are potassium chloride, potassium sulfate, potassium magnesium fertilizer and biological potassium fertilizer.
