What requirements must substrate compost meet?

Substrate compost is another renewable raw and residual material that is obtained from green waste in the spirit of a smart circular economy. However, it can only be used for peat-reduced substrates and soils if high quality requirements are met. The substrate compost used by Gramoflor comes from long-term partnerships with suppliers from the waste management sector who are as regional as possible, who know these high requirements and also achieve them with their compost. As a result, it has a good pH buffering and thus a stabilising effect. In addition, it has a good water retention capacity in the substrates. It is also a compost with a relatively low salt content as well as balanced amounts of trace elements with a good binding of nutrients. Via microbial revitalisation, the compost can contribute to the health of the plant. We only use high-quality green waste compost from the Bundesgütegemeinschaft Kompost (Federal Compost Quality Assurance Association) with rotting grade V. The RAL quality assurance guarantees a continuously consistent high quality in order to meet the requirements of a substrate for professional horticulture and the cultivation safety necessary there.
