Soil pH is a measure of hydronium ion (more commonly the H+) activity in the soil solution.Activity is similar to concentration in non-salt-affected soils.Soil pH influences many facets of crop production and soil chemistry, including availabilities of nutrients and toxic substances, activities and nature of microbial populations, and activities of certain pesticides.Soil pH is defined as the negative logarithm (base 10) of the H+ activity (moles per liter) in the soil solution.As the activity of H+ in the soil solution increases, the soil pH value decreases.Soils with pH values below pH 7 are referred to as "acid" and those with pH values above pH 7 as "alkaline"; soils at pH 7 are referred to as "neutral."Hence in present study an attempt is made to implement Embedded based Soil pH meter.
