The GP Air combines clever design with robust engineering giving a cost effective solution for poor soil structure.

Using an exclusive air delivery system, GP Air the GP Air is perfect for initiating and maintaining a healthy soil environment.

Good Soil

Good soil structures are well drained, have adequate pore space and are vibrant with microbial life.

Compaction, water logging, bad drainage and anaerobic conditions are all factors associated with poor soil structure. These are every day battles for those tending them.

Greenearth NZ Ltd

Greenearth NZ Ltd has designed and manufactured a product called the GPAir. This unique machine can penetrate deep into the soil, and aerate with little or no disruption to the surface level. Releasing a controlled blast of compressed air, the GPAir lifts and shatters the compacted layers of soil. This allows saturated soils to drain. It also allows water to infiltrate parched and dry soils.

About Soil

Soil structure determines the ability of a soil to hold and conduct water, nutrients and air necessary for plant root activity. It is the balance of soil matter, water and pore space that determines the health of the soil.

Soil compaction occurs when soil particles are pressed together reducing pore space. Heavily compacted soils contain few pores and have a reduced rate of both water infiltration and drainage.

Soil aeration affects compaction by breaking up the soil profile. The process of opening up the soil profile initiates a healthier soil environment, oxygenating the root zone, promoting the growth of beneficial soil organisms and enhancing the availability of nutrients.
