Studies on the mineral balance in paragrass, Brachiaria mutica (Forsk.) Stapf, showed that the K/(Ca+Mg) ratio only once exceeded 1.80 under different fertiliser treatments; this was taken to be due to a relatively high Mg content in the plant tissue. Fertiliser N decreased the K/(Ca+ Mg), K/Mg, and K/Ca ratios in the grass, and the percentage of nitrogen in the tissue was negatively correlated with the K/(Ca+Mg) ratio.
