Relations between the litter decomposition of Dunn Eucalyptus dunnii plantation and the deposition of N and S were studied by means of a quadratic rotation-orthogonal combination design,and regression models for the weight loss and N/S deposition were also established.

Effects of N deposition on soil fauna: a summary for one year.;

The short-term responses of soil CO_2 emission and CH_4 uptake to simulated N deposition in nursery and forests of Dinghushan in subtropical China;

Effects of simulated N deposition on soil fauna;

Summary was made on impact pattern and process of nitrogen deposition on soil carbon pool from the import and export of soil carbon content,as well as on the latest progress of researches on effect of nitrogen deposition to litter decomposition,fine root biomass and soil respiration.

The consumption of caustic soda is mainly caused by formation of sodium hydrate alumino-silicate and it can be calculated from the ratio of N/S of red mud.
