Effects of aluminum, nitrate and ammonium on the growth, potassium content and composition of amino acids in Stylosanthes

The effects of the aluminum, nitrate and ammonium interaction, in nutritive solution, were studied under controlled conditions. An analysis was performed on the growth, potassium concentrations, and percentage composition of N of the amino acids in Stylosanthes guianensis and S. macrocephala, sensit...
