ArpoLith GmbH

ARPOLITH is a German brand offering a biodegradable, earth-colored granulate designed to support plant growth and improve soil water retention. Made from natural rock flour, sands and mineral additives, it is presented as an alternative to conventional, typically synthetic hydrogel products. The granulate stores water for plants from establishment onward, while helping avoid waterlogging, and is intended to remain useful throughout a plant’s life.

ARPOLITH’s product is promoted for applications including agriculture, planting and challenging sites with soils that retain little water. The company says it can help reduce irrigation, energy and fertiliser use, as well as reliance on certain crop-protection chemicals, while supporting soil quality, planting survival and harvest consistency. Research described on the brand’s website reports longer survival during dry conditions and stronger growth in poplar trials; a customer also reports increased biomass in maize field tests. These results are presented as trial findings, not guarantees. ARPOLITH is associated with WE Chem Deutschland GmbH in Velen, Germany, and invites customers to contact the company for information or request a sample for a home basil-growing test.
