New product: Perlite for agricultural use – aeration and moisture retention
Perlite for agricultural use, with a neutral pH. Perlite is a natural, clay-silicate mineral which provides aeration and helps retain moisture in agricultural crops. It contains 3 to 4 per cent crystalline water and is of volcanic origin. It is produced mechanically, without chemical additives, by heating it to 1000 °C, the temperature at which it expands.
It has grains with a diameter of 0.63 to 4 millimetres and is produced exclusively for use in agricultural applications. It is certified to European standards and is available in 100-litre packs.
Perlite in agriculture
Perlite for agricultural use is applied by incorporating it into the soil. Due to its structure, it creates a sterile medium for plant growth. It maintains a neutral environment and thus helps to build a strong root system. Due to its white colour, it improves light reflection in greenhouses and promotes the process of photosynthesis.
Perlite for agricultural use is very light (max 140 kg/m³) and can hold 3 to 4 times its weight in water (250–300 litres of water/m³). Its air content when holding the maximum amount of water is approximately 55 per cent. It is completely free from diseases and weed seeds, whilst also acting as a temperature stabiliser. It is chemically inert and has a neutral pH (6.5–7.5). Its beneficial effects are long-lasting, as it does not decompose like other materials.
