Abstract

A site-specific long-term plot experiment was used to study the effect of continuous application of biochar-based slow-release peanut dedicated fertilizer and organic manure on the soil physical and chemical properties and yield under peanuts continuous cropping. The results showed that the application of biochar-based slow-release fertilizer could improve the contents of N, P, K and the production of peanuts. After three years of continuous application, the production of the treatment with application of biochar-based slow-release peanut dedicated fertilizer reached a maximum of 6 488 kg/ hm2 , which was higher than other treatments significantly. Application of biochar-based fertilizer could increase the content of soil organic matter, total potassium and available potassium much more than other treatments, but there were no significant difference on improving soil total nitrogen, available nitrogen, and the effect on total phosphorus was less than other treatments. With the increasing of planting years with application of biochar-based fertilizer, pH declined. The effects of application of pig manure with chemical fertilizer or corn stover with chemical fertilizer were better to prevent soil acidification than biochar-based fertilizer.
