BIOSTIMULATING ACTION
Permitted in Organic Farming
Grena Extra represents the perfect product for chamomile because it contains thin Cornunghia, visible because mixed with the organic substance of Grena Extra in pellets. Grena organic substance is obtained by THP® wet thermal hydrolysis treatment, which is the cooking of the organic substance only with the use of heat without adding chemical substances.
The gradualness of mineralization makes Grena Extra a slow release product: in just 28 days will be available for nutrition with 50% of the fertilizer units of the organic matrix to continue its disposal for other two or three months, in the meantime the buffering power of the soil begins the disintegration of the longer mineralised represented by the Cornunghia which will conclude its period of disposal of the elements in the soil just after 10-12 months. In fact with Grena Extra it is possible to have a constant and balanced nutrition of nutritional elements, particularly useful with the use of the product under a greenhouse or tunnel where the high humidity and increased heat significantly reduce the time of mineralization of all organic substances.
Grena Extra is a registered organic product but that has an interesting agronomic yield also for conventional and integrated agriculture, where the calculated contribution of the fertiliser units integrates and reduces the contribution of the mineral product in use.
