HOT OFF THE PRESS – AMENDING SUB-SOIL CONSTRAINTS

The last of the Soils Knowledge case studies is complete!

This was a trial to assess if deep ripping can aid in mitigating constraints in the 0-30cm zone of the soil profile and help move soil amendments into the sub-soil zone in medium rainfall zones on a clay soil type.

Location: Melrose

Soil Type: Red Clay Loam

Constraints: Acid throttle, sodicity, salinity and sub-soil compaction

Treatments: Ripping (30, 60 cm +/- incorporation), lime, gypsum, compos
