Determination of water content of soil mass
WebIn Tunisia, water used for irrigation is often saline, increasing the risk of salinization for soils and crops. In this study, an experiment was conducted on a tomato crop cultivated on a silty-clay soil irrigated with three different water qualities: 0, 3.5, and 7 dS·m−1. Experimental data were then used to calibrate and validate the Hydrus-1D model, which … WebReliable water content values for these soils can be obtained by drying in an oven at approximately 60 to 80°C. The percent of water content shall be calculated as follows: w = (W 2-W 3) (W 3-W 1) × 100. Where, w is Water Content Percent; W 1 is mass of container (bowl) in gram; W 2 is mass of container (bowl) with wet soil in gram
