چکیده
ABSTRACT In the Brazilian Savanna, most of soils have a low natural fertility. order to overcome this limitation, farmers use large amounts soluble fertilizers, causing environmental impacts. present study, finely ground biotite syenite (0; 600; 1,200; 1,800; and 2,400 kg ha-1) was evaluated as an alternative source nutrients electrical charges in weathered Ferralsol from Savanna. Additionally, development nutrition maize plants were analyzed. The values Ca + Mg, T, t, Zn, Cu, Fe Mn soil not affected by addition syenite, but available P K permanent increased. did increase contents P, Cu leaves, it increased N K. Increases 103, 125 128 % also detected, respectively, for plant height, stem diameter leaf dry matter. able charges, well uptake K, thus helping growth.
