For the fish pond clearing out of the mud, especially the high-density feeding of fish ponds, the mud inside the pond due to fish excrement, as well as feeding feed residue sediment, etc., making the organic content of the mud more rich, is a very good fertilizer, as a good choice of agricultural fertilizer. But some people will find that if such pond mud is applied directly to the field, it does not play the role of farm fertilizer, often playing a counterproductive role, which is not conducive to the growth of crops. The reason is that the sludge cleaned out of fish ponds is rich in organic matter, similar to "raw manure", and needs to be properly treated to be a quality organic fertilizer. So, how do we turn such
pond sludge into useful organic fertilizer?
By using the temperature of
fermentation and self-heating, it kills some germs, fungi, and various parasitic organisms and grass seeds inside. Moreover, the straw and fine soil mixed in it can solve the problem of pond mud being dry and caked. So after a cycle of full fermentation, you can make a good pile of high quality organic fertilizer!
