Title: Effect of Utilization of Biogas Slurry on Crop Growth and Soil Quality
Abstract: As the residue from the anaerobic fermentation of organic solid wastes,biogas slurry have abundant N,P,K,amino acids,vitamin,mineral elements and other beneficial biology active matters.Application of solution of biogas slurry can not only effectively promote the yield of crop,change the qualities of vegetables,but also increase the soil pH to a certain degree,prevent soil acidification,reduce salt damage,improve fertilizer efficiency.Although,long-term applying fertilizer would cause the accumulation of antibiotics and heavy metal pollute,but comparing chemical fertilizer,it was harmless.Biogas slurry utilization in China was still in exploration phase at present;society has not a safety conscious on process and utilization of biogas slurry.So,constructing irrigation and biogas slurry monitoring system which is suitable for different regions and different soil types is imperative.
