Effects of biochar and fertilizer amendments on soil acidity and soil organic carbon content on Luvic Anthrosols in Russian Far East

Abstract

The paper presents the results of a study effect of biochar together with fertilizers on the acidic properties and organic content in Luvic Anthrosols in the South of the Russian Far East during two years field experiment. As a result of the study, it was proved that the combination of biochar with organic fertilizers contributes to the preservation of organic carbon in the soil at the end of the growing season, even 16 months after application both on the drainage site and without drainage. The most effective shift of acidity values towards neutral occurs 4 months after the introduction of biochar and combination with fertilizers for all experimental variants on a non-drainage site. After 16 months the acidity values almost return to the original values of the beginning of the growing season.
