The alternative aggregates
In addition to the classic non-woven fibres used to improve riding sands, there are various biodegradable aggregates that give the riding surface better footing.
Bio Poly: This is a PLA fibre that is largely made from grain. It consists of 100% renewable raw materials and is biodegradable. The fibre has a long-fibre, hair-like structure. It creates a light weave with the riding sand. The tread resistance is improved. According to experience, the durability is approx. 3 years.
Bio Equi: The fibre consists of a bast fibre from the stems of the Corchorus plants Corchorus capsularis and Corchorus olitorius and is 100% biodegradable. The fibre has a golden and silky sheen and is also called "the golden fibre". It is characterised by a high water absorption capacity, low tensile strength (20-25 Rkm) and good rotting properties. However, it is very susceptible to rotting and has a strong odour. Bio Equi consists of woven pieces with individual threads that interlock slightly in the soil. The fibre prevents the horses from hoofing in too deeply. No valid statement can be made about the durability of the fibre. It is estimated to last 2-3 years. However, this is highly dependent on the weather conditions and the care that is given.
Cotton: Aggregates made of construction wool consist of small woven pieces and individual threads of construction wool. They are 100% biodegradable. As the fibre has a very soft structure, it is trampled on relatively quickly in the soil and is not dimensionally stable. A relatively large amount of material is needed to achieve a sufficient effect with this aggregate. The durability is less than 3 years, but also depends on weather and maintenance conditions.
Especially with regard to sustainability and environmental protection, it is certainly worth considering which type of aggregate to choose. The basic idea of not polluting the environment with biodegradable aggregates is justified. However, under the aspect of sustainability and resource conservation, the longevity of the riding surface must also be considered. Organic aggregates decay after a certain time and turn into humus. Too much humus reduces the sand quality and may even make the riding surface unusable.
