Aeration and irrigation of trees in cities / Moving large trees

Due to climate change, we increasingly need urban trees as “air conditioning”. In order to be able to develop their full effect, trees must grow large and old. To do this, the roots need sufficient space and soil compaction must be kept to a minimum.

The novel LITE-NET irrigates AND aerates tree roots extensively, efficiently and evenly. The roots can easily grow through the net and soil compaction is prevented.

The basis of the very voluminous, robust and flexible nets are special water storage fleeces. These consist of environmentally friendly geotextiles/fleeces made of sustainable polypropylene or biodegradable raw materials such as wood fibre and PLA. As these nonwovens consist of up to approx. 90% of open, interconnected air pores, they are able to conduct or drain air and water very well on the one hand and serve as water storage in addition.

The fleece nets are used in different ways. For example, they can be laid completely in a plant pit and pulled up to the surface on the walls. There the nets absorb air and water and then distribute it evenly in the root area. The water-conducting pore cross section of the voluminous fleece nets per raised side of a normal tree pit corresponds approximately to that of a DN 100 pipe. Since the fleece nets are somewhat elastic, the surrounding soil cannot be compacted completely. Air is even pumped into the soil by passing vehicles. In addition, the root-infused fleece netting improves the ground anchorage of the tree.

Due to all these properties, conventional methods such as ring drainage (pipe systems which do not ventilate large areas but only in a linear manner and usually irrigate the tree pit below the root ball) can be replaced simply and cost-effectively. This makes LITE-NET ideal for urban trees!

LITE-NET can be used for new plantations as well as for moving large trees:

Vegetation net and irrigation bag

As a start-up support for rooting the tree (planting new trees) the LITE-NET in its version as a vegetation net is placed directly around the root bales. The vegetation net can consist of long-lasting polypropylene or biologically degradable raw material such as wood fibre or PLA. An ideal combination is the addition of irrigation bags or a tree watering reservoir, whose water can be directed to the roots through the vegetation net in an efficient, fast and regular way.

In addition, the LITE-NET can be inserted into the whole tree pit when moving large trees as a tree roots screen. There it absorbs air and water in order to spread it most quickly and extensively at root level.

LITE-STRIPS as additional water reservoir

As an additional water reservoir, it is possible to mix LITE-STRIPS into the soil surrounding the root ball. The use of 100% biodegradable LITE-STRIPS Bio out of wood fibre (approx. 1 year) or PLA (approx. 5 years) prevents the raising or breaking of the tree grille, as the roots can grow into the voids liberated by the degradedLITE-STRIPSBio.

Conventional city tree irrigation

BLUELITE-NET finds a completely new application for city trees: Among the disadvantages of conventional underground irrigation pipes are bad and irregular water distribution with changing soil characteristics as well as the danger of possible obstructions and an irregular as well as uneven water supply. This is why most irrigation pipes are placed on surface. But there they often suffer damages, which again leads to water no being distributed regularly.

With the active BLUELITE-NET irrigation system, which is placed 5-15 cm below surface, the pipe is protected by a nonwoven covering against obstructions and leads the water directly into the soil and to the roots, with a contact surface a increased by a thousand. Combined with a vegetation net, the water can also be lead to the root bale. As water doesn’t evaporate and is lead to where it is most needed, a high quantity of water can be saved.


 The filter mat for protection against road salt

One of the main factors for damage to trees and hedges along roads is road salt. This is where horticultural offices, gala farmers and foresters quickly reach their limits with preventive measures.

This is why we have developed SALFIX-MAT to prevent this cost-intensive damage. Simply inserted into the tree disc – the water-permeable filter mat binds road salt for many years. This prevents damage to trees and compaction of the soil. This is how our trees survive the winter.

The advantages in comparison to common pipe ventilation systems are obvious:
