The depth of your pasture's roots is key to improving yields in your crop. Deep rooted pasture is more resilient to drought and flood, more resistant to pugging, and consequently will result in higher yields.
In the picture above, there is clear evidence of heavily compacted soils inhibiting root growth. Compaction has caused roots to grow at angles to vertical, limiting their depth and their effective uptake of nutrients.
Groundhog aerators have a unique tine action. The geometry of the tine is such that the whole tine is on a lean from perpendicular to the shaft, and is twisted about the vertical axis. Due to this lean and twist on the tines, the ground is effectively lifted and shattered across the full width of the aerator.
As a consequence of this aeration, vital nutrients - including air, water, effluent and fertilisers - are able to penetrate deeper into to the soil profile, which is now more friable and has more air pockets due to the lifting and shattering effect of the Ground-hog's unique tine.
With nutrients available lower in the soil profile, and with the soil loosened and compaction layers broken, roots can then follow after the nutrients.
It is important to note that regular aeration is often required - livestock remove the effects of a single aeration treatment in wet seasons.
