Comparison of lime- and biochar-mediated pH changes in nitrification and ammonia oxidizers in degraded acid soil

Popis výsledku v původním jazyce

Ca-amendments are recommended for soil fertility enhancement in acid soils. Biochar (Bc) can be used as an alternative for the same purpose. Biochar additions have been reported to alter microbial communities in soils and biogeochemical processes including nitrogen (N) cycling. In a microcosm experiment we investigated the interactive effects of soil pH, the type of soil amendment (lime or biochar) and the NH4+ supply on net N mineralization and nitrification in a degraded acid soil, and on the abundance of ammonia-oxidizing bacteria (AOB) and archaea (AOA). Soil was incubated under native pH and CaCO3 or biochar manipulated pH to reach pH 6,2 and 6,8 in the presence or absence of added ammonium for 70 days. Our results showed that Bc had longer-lasting effect on soil pH than CaCO3, suggesting that Bc could be a preferable liming agent. Increased pH stimulated microbial activity and led to increased N mineralization, which was higher when CaCO3 was applied. Although pH increase and NH4+-N addition ha
