Lime and calcium-magnesium silicate in the ionic speciation of an Oxisol

Scientia Agricola
Plant residues and certain fertilizers accelerate soil acidification and increase the levels of aluminum-Al+3 in soils under no-tillage (NT). Silicates act as acidity amendments and as a source of silicon as in H4SiO4.
