somministrati, determinino effetti pos<strong>it</strong>ivi sul<br />

metabolismo del comp<strong>le</strong>sso microbico, anche<br />

al<strong>le</strong> dosi più e<strong>le</strong>vate. Le trans<strong>it</strong>orie<br />

modificazioni del<strong>le</strong> attiv<strong>it</strong>à enzimatiche di<br />

den<strong>it</strong>rificazione e di idrolisi dell’urea sono di<br />

modesta ent<strong>it</strong>à e tali da non avere influenze<br />

negative determinanti sulla fertil<strong>it</strong>à del suolo.<br />

I risultati del<strong>le</strong> ricerche ci sembrano sufficientemente<br />

validi nel dimostrare una comp<strong>le</strong>ta<br />

assenza di effetti negativi sulla<br />

microflora tellurica dei reflui derivanti dalla<br />

macerazione della canapa, almeno al<strong>le</strong><br />

dosi e <strong>per</strong> gli aspetti indagati, e <strong>per</strong>mettono<br />

di ipotizzare che tali reflui possono essere<br />

distribu<strong>it</strong>i al suolo senza <strong>per</strong>icolo di alterare<br />

l’equilibrio del sistema della microflora.<br />
