Arpolith is a granular material with the primary purpose of serving as a water reservoir for soil and plants. Like a sponge the granules store water and nutrients in the ground, releasing them to plants as the soil gets drier.
Arpolith can store water at up to 30 times its own weight. The granules swell when absorbing water and shrink to their original size as the plants consume the water. The swelling and shrinking process aerates the soil, supporting a sound root structure. The granules continue to do so throughout the whole product life of Arpolith.
Many soils have only a limited capacity to store water. Irrigation and rain water quickly seep away or evaporate, so that plants suffer from water shortage even in regions where sufficient quantities of water are available. This does not happen with Arpolith: Arpolith absorbs water until the granules are fully saturated and gradually releases it again, together with nutrients and minerals. Moisture levels are maintained, since excess water is allowed to seep away. The soil quality is improved, resulting in enhanced vitality, vigour and volume of plant growth.
Arpolith has a life of around three years in the ground.  Only after that period of time does it need to be applied again. The material has a number of sophisticated features: It is non-toxic and fully bio-degradable, the granules do not cake or clump together which means they don't form a continuous barrier within the ground. They retain that feature during the whole product life of Arpolith.
Depending on the type of soil and general climatic conditions, up to 60% less water is consumed with Arpolith in place, saving water and reducing labour times.
Arpolith is suitable for a wide range of applications: Private and market gardens, horticulture landscaping, agriculture and forestry, golf courses and turf on sporting areas. It helps to stop desertification of the earth since with Arpolith in place less irrigation water is needed and plants can be grown in dryer soils. Arpolith is also valuable to equestrian facilities like ménages, arenas and tracks, where it is applied for dust reduction or to prevent excessive mud and puddling that can occur after heavy rain.
