A system and a method for reducing emission of greenhouse gasses is provided, in particular at least one of methane, laughing gas, nitrogen oxides, and ammonia from slurry stored in one or more slurry storage tanks. The method includes continuously maintaining slurry stored in a slurry storage tank under acidic conditions. The method includes the steps of: A: monitoring pH in the slurry present in the slurry storage tank by one or more pH sensors arranged in contact with the slurry in the slurry storage, B: checking if the detected pH exceeds above an upper threshold, such as an upper threshold set at pH=7, C: activate acid addition when the monitored pH exceeds the upper threshold, D: while stirring, adding acid until pH in the slurry is adjusted to within a range between the upper threshold and a lower threshold, such as between pH=2 and pH=7, in particular between pH=5 to pH=7, or more preferred pH=5 and pH=6, and repeating steps C-D when the detected pH of step A exceeds the upper threshold.

This invention provides a method of preparing organic fertilizer by combining agricultural wastes and livestock manure, belonging to the technical field of preparing organic fertilizer. 1. Collect agricultural wastes. 2. Crush agricultural wastes to fragments of 1-4 cm in length after removing debris, and make a composting bed, 110-160 kg per cubic meter. 3. Prepare maturing agent: Put water into a plastic container at room temperature for 24 hours, then add maturing agent, such that the mass ratio of water to maturing agent is 1000:5, stir, and leave it 24 hours after stirring. Then spray evenly on the composting bed. 4. After step 3, the water content of the compost is controlled at 55%-65%; the bulk density is controlled at 110240 kg/m{circumflex over ()}3; and the proportion of raw materials is treated by slot chelation. 5. livestock manure is sprayed evenly on the composting bed every day, and the sewage of livestock and poultry manure is controlled at less than 85%, and 850 kg of livestock and poultry manure is sprayed on every cubic meter of the composting bed every day. Fermentation 1 to 2 months later.
