The researchers measured how easily water moves through different types of soil. They used special equipment to test the soil's ability to let water pass through it when it's fully saturated. They found that sandy loam soil had an average hydraulic conductivity of 0.00142 cm/sec, while clay soil had a lower average of 0.0000146 cm/sec. This information is important for understanding how water moves through soil, which can help with things like managing water resources and predicting runoff.
