Environmental effect of improved forage fertilization practices in the beef production chain.

Feeding is one of the most important factors influencing production efficiency and the environmental impact of livestock production. This study evaluates the possibility of reducing the impact of beef cattle production by optimizing the fertilization management of home-grown forage on the same farms. To this end, two scenarios were compared on two beef cattle farms in northern Italy, a baseline scenario (BS) and a scenario with optimized management (OMS) in terms of nitrogen fertilizer use.
