Values followed by a different letter in each column are significantly different (p < 0.05) according to Tukey's LSD procedure. C = control, L = lime (2250 kg ha⁻¹), AS70 = ammonium sulphate at 70 kg ha⁻¹; AS211 = ammonium sulphate at 211 kg ha⁻¹; AN70 = ammonium nitrate at 70 kg ha⁻¹; AN211 = ammonium nitrate at 211 kg ha⁻¹; AS70L = ammonium sulphate at 70 kg ha⁻¹ + lime; AS211L = ammonium sulphate at 211 kg ha⁻¹ + lime; AN70L = ammonium nitrate at 70 kg ha⁻¹ + lime and AN211L = ammonium nitrate at 211 kg ha⁻¹ + lime.
