High-quality organic fertilizer made from organic mud

Abstract

The invention discloses a high-quality organic fertilizer made from organic mud. The high-quality organic fertilizer is prepared from the following raw materials: 50% of organic mud, 10% of wood powder, 4% of brown powder, 6% of tobacco powder, 20% of straw raw materials, 5% of vegetable oil cakes, 4% of humic acid, 0.4% of a straw fermentation agent and 0.6% of a microbial agent; the water content of the organic mud is 70% to 75%. According to the high-quality organic fertilizer, plant straw is added to decompose and lower heavy metal indexes, it is guaranteed that the product quality is 100%guaranteed, and the organic combination of straw and sludge can be further achieved; the microbial agent and the straw fermentation agent are added, the ratio of raw materials to auxiliary materialsis optimized, the content of organic matter in the prepared organic fertilizer is far higher than the national standard, the nutrient reaches 7.3%, and each heavy metal content index is also far lowerthan the national standard.

Description

technical field [0001] The invention relates to the technical field of organic fertilizers, in particular to a high-quality organic fertilizer made from organic mud.
