Soil microbial biomass and activity in Chinese tea gardens of varying stand age and productivity by Han, Wenyan, Kemmitt, Sarah J., Brookes, Philip C.

“…Tea ( Camellia sinensis) is a globally important crop and is unusual because it both requires an acid soil and acidifies soil. Tea stands tend to be extremely…”

Soil acidification used as a management strategy to reduce nitrate losses from agricultural land by Kemmitt, Sarah J., Wright, David, Jones, David L.

“…pH is known to be a primary regulator of nutrient cycling in soil. Increasing soil acidity in agricultural systems has the potential to slow down N cycling and…”
