How Subsoil Aeration Works

Posted by Sam Searle on Aug 30, 2019 3:53:00 PM

Over time as stocking rates have increased, machinery and implements become heavier and larger, along with repeated tillage operations many farmers have begun to see their pasture growth and crop yeilds decrease due to subsoil compaction issues. Subsoil compaction is easily overcome with aeration, read on to find out how subsoil aeration works.The effects of subsoil compaction are many, however they all share the same root cause which is a layer (in some cases many layers) of compacted soil.

How subsoil aeration removes compacted layers

Compacted soil layers prevent downward root growth, this causes roots to grow horizontally and matt in the upper soil layers where they are prevented from reaching lower soil layers where nutrients and moisture can be found. This causes lower growth and yields in pasture and crops.

Subsoiler legs run through all compacted soil layers (200mm to 450mm deep), this lifts and fractures the soil structure without surface disturbance to existing pasture cover. This increases the soil porosity and permeability as the compacted layers are removed. This improves the overall soil conditions.

Once the compacted layers are removed and the soil becomes more permeable, oxygen levels increase along with making it easier for roots to grow downward with greater vigour. This increases the overall pasture growth and crop yields while making pasture and crops more resilient. Find out more benefits here: Subsoil Aeration Benefits
