WHY AERATE THE SOIL ? BY DEEP AERATION SPECIALISTS TERRAIN AERATION

Why should we aerate ? To answer this , we need to acknowledge that the roots of all plants need to respire . They do not breathe as we do , but they need to absorb oxygen and emit Carbon Dioxide . Roots can only thrive where this exchange is possible , so where do the roots get their oxygen ?. The oxygen is in the air in the air spaces between the soil particles and this is why gardeners always aim to produce a soil with a crumb texture , which has air spaces between the crumbs . It follows that if these air spaces are closed , the roots have little or no oxygen to draw upon and will tend to die back away from such areas .
If we want our plants to thrive , we must ensure that the air can penetrate the soil and we do this by aeration . So , to answer the question directly : we aerate to put air into the soil for the roots to use to respire and to keep the soil sweet . Aeration also allows water to percolate into the ground surface and a soil that allows free percolation is unlikely to remain waterlogged for very long and so will have a firm dryish surface soon after heavy rain .
How to aerate ? There are a lot of different techniques available starting with a good old garden fork pushed into a lawn , through spikes the size of smallish nails on a pedestrian pushed roller through large spikes that reach 150mm into the surface to slitting knives some of which simply slice into the turf to others that slice the turf and shake it . We then enter the world of deeper aeration .
Terrain Aeration specialises in deep penetration aeration to a depth of one metre where a blast of compressed air fractures the soil , creating fissures that allow drainage and oxygen to the roots of the grass or trees .

THE BEFORE AND AFTER OF ONE METRE DEEP AERATION

COMPACTION AND WATERLOGGING STOP PLAY . DOWNTIME COSTS MONEY .
Terrain Aeration ’ s long-term treatment reaches one metre deep where compressed air blasts the compaction . The soil is opened up for good drainage and a healthy sward with minimum disruption . We have been successfully aerating sports turf , bowling greens , golf courses , parks , trees and gardens for over twenty-fi ve years .
