The use of slurry in agricultural terrain is highly important from the standpoint of a circular economy and therefore the use of all resources available, reducing waste to a minimum. Slurry used directly in the field is injected into the ground in accordance with the dictates from the most recent studies in order to avoid creating any environmental problems. If the slurry is used properly, it helps enrich (even if not in a very stable form) carbon in the soil and provide humidity to the terrain. Distribution of the slurry associated with amendments is suggested to favour the absorption of nutrients.
