Zibo organic vegetables: good place for biogas residue

The Sukong Dairy Breeding Cooperative of Nanjiao Town, Zhoucun District, Zibo City, Shandong Province, makes full use of the biogas slurry and organic vegetables produced by the dairy farm biogas digesters, with remarkable results.

  In a winter-heated high-temperature greenhouse, several workers are mixing the biogas slurry into the soil. According to reports, biogas slurry is rich in organic matter, humic acid, crude protein, nitrogen, phosphorus, potassium and trace elements. It is a high-quality organic fertilizer. Directly spraying biogas slurry as fertilizer can control crop pests and diseases. Biogas slurry can produce the most "pure" organic green vegetables. According to the village branch secretary Shengye and the introduction, only this 1.5- mu vegetable greenhouse used more than 60 tons of biogas slurry as the base fertilizer.

  It is understood that these good fertilizers are derived from the Yonghui Dairy Livestock and Poultry Farming Pollution Control Biogas Project at the Sukong Dairy Breeding Base. The project is the first to ZHOUCUN-based gas supply to the villagers large-scale biogas projects to receive financial support from the central one million yuan, the provincial capital of 250,000 yuan financial support, with a total investment of 4.15 million yuan, in May 2010 and put into use. In this less than one year trial period, the project not only processed the manure produced by more than 1,300 cattle in the farm , but also enabled the biogasification of the cooperative members' production and life.
