Future proofing agricultural production through effective management of acidic soils

Abstract

Key findings • Surface-applied lime that is only incorporated by the sowing operation has limited effect on increasing pH and decreasing exchangeable aluminium percent below the surface 0–5 cm layer. • Incorporation of lime aids lime solubility, increasing pH to the depth of mixing. • Analysed results within 12 months of lime application can be misleading, particularly in dry seasons; they do not capture the full effect of lime rate, incorporation method and reacidification processes.
