The Geo Injector Maxi is an efficient and versatile soil aeration and injection device equipped with a large material tank and compressed air storage system. Engineered for demanding tasks, the Maxi provides the operator with the targeted injection of granules, water reservoirs, liquid fertilizers, water and air into highly compacted soils. Combining performance and affordability, it offers a broad range of functions that make it a reliable tool for both commercial users and more professional working environments.
Versatility above all else!
This mobile supply unit is designed for ease of transport and efficient movement across a variety of different terrains, supporting flexible operation within a 5-metre working radius. Capable of being operated by one person directly at the injection lance simplifies control, allowing precise management of aeration and injection at different soil depths on the fly. The injection quantity can be intuitively controlled via the trigger pull length, giving users immediate response and tactile feedback. A pressure relief valve and quick-release coupling allow for fast filling of the 20-litre storage tank, reducing downtime between tasks. For additional functionality, an optional compressed air cleaning unit can be installed, utilizing advanced filter technology to clean both the aeration system and the injection lance.
Operating at pressures of up to 10 bar of pressure, the Geo Injector Maxi is well-suited for aerating medium to heavy soil compaction with relative ease, especially in urban and high-traffic landscapes. In these environments, a dependable soil injection machine is essential for restoring compacted ground. By injecting compressed air through a lance, the device breaks up dense soil structures, restoring permeability and enabling oxygen, water, and nutrients to reach plant roots more effectively.
The Benefits and Necessity of Soil Aeration
Urban environments have seen substantial changes in climate conditions with prolonged dry periods and increasingly extreme weather events becoming more frequent. As a result, ensuring healthy root environments for urban trees and vegetation has become a critical challenge. Soil in undeveloped or heavily trafficked areas is often compacted, creating conditions that are hostile to new growth. Aeration, therefore, plays a central role in supporting root development and maintaining soil health. It ensures a steady supply of water and nutrients while boosting long-term plant resilience to drought, disease, and harsh conditions.
With its ability to eliminate soil compaction at working pressures between 5.0 and 8.0 bar without harming roots, the Geo Injector Maxi offers a powerful, practical solution. For professionals looking to improve soil quality quickly and effectively, this tool stands out as a dependable choice. Whether you’re planning future landscaping work or addressing existing soil issues, the Geo Injector Maxi is a straightforward, proven solution that delivers lasting results.
Add-ons & Extra Equipment
GEO Injector Fluid
A compact unit for the injection of liquid and gel suspensions, the Geo Injector Fluid provides you with sustained and constant injection quantity.
Soil aeration is performed through a 20-litre buffer tank which, after loosening the soil, has fluid gently injected into the ground via a separate hose with pressure ranging from 2 to 7 bar of pressure. This process can be done at varying depths to suit different needs. The pneumatic one-man operation, located directly at the injection unit, allows for flexible work within a 10-meter radius around the supply unit. The injection quantity is precisely adjusted using a time valve to ensure even distribution.
A 3.3-meter-long suction hose facilitates operation with large storage containers (such as IBC containers), and a pneumatic circulation function prevents the suspension from settling. The compact device can be easily attached to the storage container or, optionally, to an available work-and-transport unit using an adapter plate. The device operates at a pressure of up to 10 bar.
VOGT Air Injector
With a focus on user convenience in mind, the VOGT Air Injector is designed to be operated in a wide range of environments and on all of our Geo Injector products. Featuring a lightweight design, excellent ergonomics, and an intuitive triggering mechanism, the VOGT Air Injector is a fantastic add-on for soil aeration activities.
Capable of being quickly attached to any VOGT TurboSpade using a quick-change system, the Air Injector is capable of extremely fast set-up and adaption in the field. Its injection spear is driven into the ground by the TurboSpade and when the control lever is released on the control console, the spear breaks the soil apart and decompacts it. The intensity of the air blast can be controlled with the shut-off valve at the air inlet, allowing for the operator to wield it with great precision. The Air Injector is compatible with a variety of TurboSpade lengths allowing you to select injection pipes ranging from 30cm to 200cm.
The valve-controlled triggering technology releases air in a sudden, high-pressure burst, effectively breaking up and aerating the soil. This allows the spade to gently break up dense, compacted or sooty soils requiring little-to-no physical effort. Loosening the soil with this device provides several key benefits. First, it allows rainwater to penetrate the soil more efficiently and spread evenly, which might otherwise pool on the surface of the soil instead and become a host of several serious health issues for plants and animals alike. Additionally, it also helps facilitate the flow of nutrients throughout the soils, allowing a better distribution across a wider range and thus improving the health and resilience of plants and trees in general.
Improved Water Infiltration and Nutrient Distribution
Loosening compacted soil with the Air Injector offers immediate and long-term benefits. It enhances the soil’s ability to absorb rainwater, helping it to spread evenly rather than pooling at the surface—where standing water can lead to plant stress, disease, and other environmental issues. Additionally, improved soil structure supports better distribution of nutrients, increasing the health, resilience, and longevity of trees and plants in both urban and landscaped environments.
Once the soil has been properly aerated, it becomes significantly easier to introduce liquid fertilizers, soil additives, or nutrients. In hard or compacted conditions, these beneficial substances often fail to reach the root zone and are easily lost through runoff. With the VOGT Air Injector, materials are delivered more effectively into the loosened soil profile, ensuring better absorption and lasting results.
