The advantages of grass-clover mixtures in ley farming are manifold. An Agroscope study now shows that their highly efficient use of available nitrogen also keeps the risk of nitrate leaching low.
Agroscope has calculated that limiting concentrates to 365kg per cow and year and a maximum concentrate crude protein content of 18% could make a positive contribution to the nitrogen reduction path without negatively impacting profitability.
Greenhouse gas calculators can assist in identifying measures to reduce emissions on farms and in quantifying the effect these measures can have. For this to be successful, it is essential to know the scope and limitations of greenhouse gas calculators.
