The polymeric coating of granules provides controlled release of nutrients depending on temperature and humidity (CAR-technology), which ensures the supply of nutrients according to plant requirements.
Thanks to its even, fine granulation and resistant coating Top Substra can be applied easily and homogenous into the substrate.
Top Substra can be used for the preparation of substrates from different types of peat.
