chapter 7 nutrient leaching css.cornell.eduin contrast to nitrate and sulphate, phosphate is immobile in most soils because of precipitation and adsorption to mineral surfaces, and leaching is therefore negligible, except in certain very sandy and organic soils (wild, 1988) (see section 5.3). dissolved organic phosphorus forms are more mobile in soil than phosphate (havlin et al., 1999
