    Parent material and altitude influence red soil acidification after converted rice paddy to upland in a hilly region of southern China

    Land use conversion from rice paddy to upland has been shown to decrease soil pH due to enhanced proton production from nitrification of ammonium-based N fertilizers and base cation loss. Parent material and a...

    Intensified soil acidification from chemical N fertilization and prevention by manure in an 18-year field experiment in the red soil of southern China

    Soil acidification from chemical N fertilization has worsened and is a major yield-limiting factor in the red soil (Ferralic Cambisol) of southern China. Assessment of the acidification process under field con...

    Nitrification and acidification from urea application in red soil (Ferralic Cambisol) after different long-term fertilization treatments

    Long-term manure applications can prevent or reverse soil acidification by chemical nitrogen (N) fertilizer. However, the resistance to re-acidification from further chemical fertilization is unknown. The aim ...
