Effectiveness verification method of cow dung organic fertilizer

The invention discloses an effectiveness verification method of a cow dung organic fertilizer, and relates to the technical field of organic fertilizers, and the technical scheme is characterized in that the verification method comprises the following steps: S1, setting a test group and a control group; s2, determining the ratio of the cow dung to the auxiliary materials, and uniformly mixing to obtain a first mixture; s3, calculating the carbon-nitrogen ratio of the first mixture of the experimental group and the control group; s4, when the carbon-nitrogen ratio is lower than 25: 1, urea is added into the first mixture, and a second mixture with the carbon-nitrogen ratio of 25: 1 is obtained; s5, adding the second mixture into high-temperature fermentation equipment for fermentation, and taking out the second mixture from the fermentation equipment when the moisture content of the second mixture in each test group reaches 50% to obtain a third mixture; s6, sampling the third mixture to obtain a sample; and S
