Surface soil acidity (0–10cm) limited crop yield by about 8–12%.
Deep placement of reactive phosphate rock or organic matter (OM) achieved yield gains of up to 18% compared with surface-applied lime.
Deep placement of OM may induce manganese (Mn) toxicity.
The interaction between subsurface pH increase and nutrient release needs further investigation.
