Anthrosols, soil profile, physical properties, land use pattern
Jianghan Plain is one of the most important commodity grain-, edible oil-, and cotton-growing areas. There are 764 thousand hm2 of medium-low yield fields in the area affected by waterlogged soils, which accounts for 40.6% of the area of anthrosols. We chose Sanhu Farm as a study area to research if the present land use patterns match the physical properties of anthrosols profiles. Eleven soil profiles were randomly selected and samples from respective soil horizons were taken back to the laboratory for selected physical analyses. Measurement of some physical properties of the 11 profiles such as hardness and water table were made in the field, while water content, bulk density and porosity of every soil horizon were analyzed in the laboratory. The results show that land use patterns of four profiles did not match their soil physical properties totally; the physical properties of other three profiles needed to be modified in some way to match the present land use patterns. There are low water table and poor drainage problems in some profiles. Changes to soil use patterns, improve drainage ability and application of more organic fertilizers should be prime measures to improve soil producing ability in this area.
