The use of cut tree branches.
As a result of the cut, there is usually an accumulation of significant amounts of branches. In the past, such branches were usually burned. Currently, it is forbidden to burn them within cities and settlements due to the safety of the environment and protection of air purity. Very often, such branches are disposed of in landfills, which, due to the large volume of this material, creates problems and costs related to loading and transport.
The cut branches are, however, a valuable material, which can be used for various purposes. The exception is tree branches infested with dangerous diseases or pests; such branches should be burned for preventive reasons. After shredding, healthy branches constitute a very valuable material for various use in gardening and in arranging green areas. This material is most often used to cover the soil surface (mulching) in the vicinity of various plants. The advantages of such mulching include securing the soil against crusts limiting air access to the roots; protection against direct evaporation of water from the soil surface; preventing water from running off the surface during heavy rainfall, which is especially important on significant slopes; hindering weed infestation on the soil surface; protection against deep freezing; providing nutrients with progressive decomposition and promoting the development of microflora and soil fauna.
Shredded branches can also be used as loosening admixtures added to the soil in the cultivation of various plants. However, the use for this purpose requires the composting of this material for 1-3 years. During composting, shredded branches can be mixed with leaves, torfem, manure, shredded bark and other organic materials. Depending on the purpose of such compost, you can also add mineral fertilizers to it and regulate its pH. An additional advantage of composting is the ability to destroy various factors that cause plant diseases. The composted shredded branches are most used, as before, when mulching the soil surface around rhododendrons (Rhododendron), many evergreen plants and some perennials.
Shredded branches are also successfully used to create the paving of various roads and walking paths. This method is especially recommended in parks of a naturalistic nature and in forest parks, and even in forests with organized walking routes. Such a surface is made by spreading a 5-10 cm layer with a width depending on the expected traffic intensity, not exceeding the usual 1-1,5 m. The surface of shredded branches not only looks in harmony with the surroundings, but it allows comfortable walking at any time of the year, which is especially important there, where heavy clay soils make it impossible to walk in the spring and autumn or after rain. Moreover, such a layer protects the soil against damage, and even improves its properties.
It is highly recommendable to use this material to create surfaces for children's playgrounds, especially in these places, where children risk falls and cuts, so most often at the slides, balance beam etc..
Drawing. Machine for shredding branches.
The comminution is carried out with the use of specially designed machines. Branches with a thickness of up to 80 mm. Some machines of Western production allow for shredding branches with a thickness of up to 120 mm. Most of the machines used for this purpose have devices that enable the regulation of the degree of grinding, depending on the intended use and use of this material.
