MASTER - Soil acidity and lime responses


This Primefact shows long-term trends of soil pH and aluminium (Al) at the MASTER site (Managing Acid Soils Through Efficient Rotations).

Subsurface soil pHCa at 15–20 cm depth could increase by one unit over 20 years by maintaining an average soil pHCa of 5.5 in the top 10 cm.

Exchangeable aluminium at 15–20 cm depth decreased from 42% to below 10% over 13 years as a result of liming.
