    The Effect of Leaching on Iron Levels in Soil

    Mar 14, 2012 The fairly intense disturbance of soil surfaces by mining activities may make soils susceptible to water and wind erosion, thus contributing to sediment loading in local or regional stream systems that reduce water quality and aquatic habitat..As soil pH increases the ferrous iron becomes ferric iron. One key factor that influences soil pH, and consequently iron levels is the process of leaching. Leaching is the process of washing away nutrients and other dissolvable substances from soil by adding large amounts of water to the soil. The
