Livestock manure fermented organic fertilizer and preparation method thereof

Abstract

The invention discloses livestock manure fermented organic fertilizer and a preparation method thereof. The livestock manure fermented organic fertilizer utilizes a certain proportion of livestock manure and breeding industry wastes as main raw materials and a specific ratio of specific microbial agents and has good effects. The livestock manure fermented organic fertilizer solves the problem thatthe traditional single-ingredient manure has high N content and high water content and is not suitable for aerobic fermentation. The preparation method utilizes raw materials in a wide range, does not limit the livestock manure type and utilizes breeding industry wastes such as straw powder, bran coat powder, distiller's grains, medicine wastes and mushroom stalks as accessories. Through use of the microbial agents, the fermentation cycle is controlled in 40 to 60 days and is significantly reduced. The decomposed material satisfies the standard of commercial organic fertilizer.
