Research Progress of Biochar, Pyroligneous Acid and Organic Fertilizer Mixture and its Components in Agricultural Production

With the growing amount of the chemical fertilizer consumption and agricultural wastes, non-point pollution of agriculture has been one of the problems threatening world crop production, especially considering the urgency of climate change. In this paper, a review of the research of biochar, pyroligneous acid and organic fertilizer mixture is given. And agronomic and environmental benefits that can potentially be derived from the application of this soil amendment in soils are discussed.
