Natural treatments in the vineyard

First at Castello di Fonterutoli and then at Belguardo and Zisola, the Mazzei family has undertaken a program of sustainable management of their farming activity with the objective of guaranteeing the stability of the ecosystem and its biodiversity.
This lead to the complete elimination of weeding and chemical topdressing, recycling of production waste (shoots, grape stalks, marc, olive pomace, and horse manure) for the production of company compost to be utilized as completely organic fertilizer.
This is complemented by the exclusive use of green manure with the objective of improving the content of organic substances in the soil naturally, enriching at the same time the biodiversity of the agro-ecosystem. For this purpose plant extracts such as field beans, common vetch, sainfoin, clovers, oat, barley, blue tansy, mustard, pasture hawksbeard, lupin beans, pea, horseradish are utilized, which after being sowed in alternating rows are cut after germinating.
Particular attention is given to biological pest control with the use and launch of helpful insects, especially with respect to fighting the vine moth, the main vine parasite.
