Aluminum (Al) toxicity imposes a significant limitation to crop production in South Western Australia. This paper examines the impact of surface-applied lime and gypsum on soil solution chemistry short term (1 year) long-term (10 years) water limited environments. In experiments, we measured using paste extract profile samples collected depth 50 cm. We then used chemical equilibrium model MINTE...
