14 DIARIO DELLA VENDEMMIA 2022 | SAN POLO Green manure 2022 One of the processes we particularly care about is green manure, i.e. the sowing of different varieties of essences and plants which allows the soil to be fertilized in a natural way. The soil is preparing to face a new year and for this reason it needs organic substances that bring nourishment and vigor. The essences sown this year are: legumes (Alexandrian clover, squarroso clover, vetch, field beans, protein pea) which release nitrogen into the soil creating a natural fertilization; brassicaceae (mustard and horseradish) with the task of decompacting the soil, favoring good oxygenation and healthiness. Finally, the floral essences including phacelia and crimson clover which produce colorful flowers and attract insects to the vineyard, helping to create a balanced ecosystem in which beneficial insects fight harmful ones by protecting the vines. 15
