How to apply biogas slurry

The biogas slurry is taken out from the biogas digester, clarified, and the gauze is filtered and applied to prevent clogging of the sprayer. Spray once every 7-10 days. Generally, in the spring, autumn and winter, after the dew is dry (about 10 o'clock), it is better in the summer evening. Do not spray it before high temperature and heavy rain at noon. 1 part of the biogas slurry at the seedling stage plus 2 parts of clear water; high temperature in summer, 1 part of biogas slurry plus 1 part of clear water, lower temperature, and old leaves (miao), can be directly sprayed without adding water. The biogas slurry should not be mixed with alkaline fertilizers such as grass ash and lime to avoid loss of nitrogen fertilizer and reduce fertilizer efficiency.
