Using biogas from sewage irrigates for pepper plantation not only offer nutitient for pepper plants but also help to save the input costs.

With the scale of hog barn is 20 pigs meat, 15m3 biogas volume contraction, with 2 sewage settling tank, he can use alternate watering for 1 ha pepper.

According to Mr. Lap’s point of view, when using biogas sewage to irrigate for pepper plantation, the growth rate of leaves and branch of pepper plants are better:  more green, durable, thicker, reduced pest, the rate of loss less effective yield estimate increased over 15% compared with the previous year. Our sense is found, the bunch of peppers have many fruits, large seeds and strong, bright color.

Mr. Lập said that, the households in the area are afraid to use biogas to irrgate for pepper plantation, they consider that the pepper plants will die after that, after Mr. Lap brave to using the biogas to irigate the pepper plants, he got a remarkably effects and immediately reflected on his own garden, the farmers in the region have started successfully this model and untill this current time the model have been popular, multiple to many other areas. When applying this model, family and households can save in the cost of fertilizers and plant protection chemicals.

According to research of the Soils and Fertilizers Institute, National Institute of Livestock and Agricultural University, the use of biogas as fuel, water discharge also contains 93% water, 7% dry  matter in which 4, 5% are organic compounds and 2.5% is inorganic. The main components of the water discharge include organic materials in solid form, the soluble nutrients (fertilizer characterized and land reclamation), and trace elements (Cu, Zn, Fe, Mn…), the newly formed cells in the resolution process. The content of nutrients N, P, K in water discharge: from 0.37 to 0.80 g / l N; from 0.099 to 0.31 g / l P2O5; 0.32 to 0.56 g / l K2O. According to the documents of the Research and Training biogas Centre in China, 1m3 of water discharge approximately 0.16 to 1.05 kg N equivalent to 0.35 to 2.3 kg of urea. Compared with the manure discharge water equivalent protein content. Thus, the barn has a wash out excess water to the second tunnel (sedimentation) and spills; This country has been settled, there is very little odor, not even smelly.

Thus the use of effluent from biogas is a very good form of organic fertilizer for plants to increase productivity, reduce input costs in agricultural production, not only improve the quality of agricultural products but also protect the common environment for the community.
