Changes in some physical properties of the soils tread with wheat straw and rice husk under the rotation of white-head cabbage, tomato and wheat

This study was carried out silty clay (SiC) textured soil and silty land (SiL) textured soil in order to reveal the changes in some physical properties of the soil in white-head cabbage (WHC), tomato (T) and wheat (W) rotation after the application of wheat straw (WS) and rice husk (RH). Soil organic matter (OM), bulk density (BD), total porosity (F), aggregate stability (AS), mean weight diameter (MWD), field capacity (FC), volumetric water content (Ɵ), penetration resistance (PR), relative saturation (RS) and initial infiltration (In) values were determined, after harvest of each plant. As the results of the experiments pointed out, soil OM contents and F values increased, while BD values decreased after WHC, T and W harvest with WS and RH application. With a higher C/N ratio, WS application increased soil OM content more than RH application. The lowest BD, AS, and MWD values were generally obtained after the WHC and T harvest, and the highest BD, AS, PR and in values after the W harvest. Soil OM content showed very significant negative relationships with BD (-0.561**), MWD (-0.680**) and RS (-0.528**) in the silty clay (SiC) textured soils, while it showed very significant negative relationships with BD (-0.809**), AS (-0.543**), MWD (-0.830**), PR (-0.555**) and very significant positive relationships with FC (0.728**), Ɵ (0.814**), RS (0.767**) in the silty loam (SiL) textured soils.
