If you want to reclaim a saline soil,which of the following practices would you most likely use? A)Add CaCO₃ to reduce the exchangeable Na⁺ level. B)Leach the soil with low salt containing water. C)Leach the soil with water having a high SAR ratio. D)Leach the soil with water high in Ca²⁺ and Mg^2+. E)Leach the soil with water high in bicarbonates.

Leaching the soil with water high in Ca2+ and Mg2+ helps in replacing the exchangeable Na+ ions in the soil with these beneficial cations, which can improve soil structure and plant growth. Addition of CaCO3 would only reduce the exchangeable Na+ levels temporarily and may lead to an increase in soil pH, while leaching with low salt containing water, high SAR ratio water or water high in bicarbonates may not effectively reduce the salinity or improve soil quality.
