Effects of defoliation and nitrogen on carbon dioxide (CO₂) emissions and microbial communities in soils of cherry tree orchards.

ABSTRACT:

Background

In farmland, microbes in soils are affected by exogenous carbon, nitrogen, and soil depth and are responsible for soil organic carbon (SOC) mineralization. The cherry industry has been evolving rapidly in northwest China and emerged as a new source of income for local farmers to overcome poverty. Accordingly, it is highly imperative to probe the effect of defoliation and nitrogen addition on carbon dioxide (CO₂) emissions and microbial communities in soils of dryland cherry orchards.

Methods

CO₂ emissions and microbial communities were determined in soil samples at three depths, including 0-10 cm, 10-30 cm, and 30-60 cm, from a 15-year-old rain-fed cherry orchard. The samples were respectively incubated with or without 1% defoliation under th
