Effect of sod‐production on soil qualities in Beijing areas

摘要：

Two sod‐production farms were investigated to make it clear how sod production effects on soil quality.The results showed that the soil chemical property had not been influenced by sod‐production.From the observation of soil profile, about 10cm fertile topsoil was taken away by 7 years sod‐production on Dongbeiwang Nursery.Compared with the control, the bulk density of topsoil was increased and the porosity was decreased on both nurseries.It means the topsoil in the production of sod became compact, which was mainly caused by rolling.The results of particle size distribution showed that sod‐production had no effect on the improvement of soil structure.
