| Abstract: | A method of field sampling coupled with lab analysis was used to investigate the cumulative state of soil organic matter,nitrogen,phosphorus and potassium in top soil layer as well as their pattern in soil profile under greenhouse cultivation in the suburbs of Wuhan,Hubei Province.Meanwhile the pH changes were analyzed.Results showed that the soil organic matter content in top layer of greenhouse soils increased by 14.7% and 36.7% respectively as compared with that of the uncovered vegetable soils and cotto... |
