The impact of different levels of salt in water was studied on how water moves through different types of soil. The researchers found that as the saltiness of the water increased, the soil's ability to let water pass through also increased. This effect was more pronounced in clay soil compared to sandy loam soil. When the soil was almost completely saturated with water, sandy loam soil allowed water to move through more easily than clay soil. The researchers also found that certain equations were better at predicting how water moves through the soil than others.
