What role does soil play in the selection of a plot?
According to Vaastu Shastra, a plot with soil that has a large salt content is considered to be inauspicious. The ground water table should be minimum 10-12′ below the existing ground level and maximum 30′. It should not have any sanitary back-filled or reclaimed soil or rubbish, bones, hair and other filthy material. The soil should be fertile and free from any decrepit or dead material.
