It should not be stored for a long time. That is, take it out from the biogas digester and directly pick it into the field or the soil. If it is too busy, it can only be piled up outside the pool for a day or two. After a long time, the available nitrogen will evaporate. Experiments show that the biogas slag fertilizer is dried in the open air, the total nitrogen loss is about 65%, and the ammonia nitrogen loss is 87%.
Biogas slag fertilizer should be used as a base fertilizer. Applied to paddy fields, it is best to apply it in the field, so that the mud and fertilizer can be combined. The application amount per mu is about 2000 kg. It is best to apply it in dry soil, such as acupoint application and ditch application, and then cover a layer of about 100 mm. Thick soil to reduce the volatilization of available nutrients.
Biogas and water fertilizer should be applied as top dressing. When applying, it should be diluted with water according to the quality of biogas fertilizer and crop growth, so as not to damage the young roots and young leaves of crops.
Biogas fertilizer is combined with chemical fertilizer. Ammonia water and ammonium bicarbonate are nitrogen fertilizers with low production costs, which are alkaline and have a volatile loss of fat. The combination of biogas slurry with ammonia water and ammonium bicarbonate can help the fertilizer dissolve in the soil, absorb and stimulate the crop to absorb nutrients, and improve the utilization rate of fertilizer. It can be applied by adding 0.5~1 kg of ammonium bicarbonate or ammonia water to every 50 kg of biogas slurry.
The combination of biogas slag fertilizer and superphosphate can also improve the fertilizer efficiency of superphosphate.

Powder carbon is Huahui Company's third series of
products. The common produced varieties
are 30x200mesh, 60x200mesh, 100x200mesh, <200mesh, <325mesh etc.
Powder
activated carbon, which is grinded into suitable powder size with qualified
activated carbon,is the third main products of HuaHui Company. Because of its
powder state, better diffusivity, it can full touch to the reaction
material. Meantime, it is applying to
disposable recovery treatment of filling
water and industrial waste water with its high efficient adsorption, moreover,
also used for refining and
decolorization of liquid. The types we manufacture through the year
include HF-30x200, HF-60X200,HF-100X200,HF-325 etc.
This high efficient carbon with powder size aims to reduce the
content of hydrargyrum vapor discharged from fire coal power plant and fire
furnace. It achieves the chemical and physical treatment to the hydrargyrum
among the smoke gas by attaching bromine into the developed micropore
organization. The hydrargyrum adsorption capacity of [Huahui" Demercuration Carbon can get more
than 0.3mg/g.
