Cows stand among manure on the ground at a dairy farm in Oldetrijne, in the Dutch province of Friesland, Netherlands March 15, 2023. Dutch farmers are worried about plans by the government to limit the amount of nitrogen in the soil and water blamed on overuse of fertilizers. If nitrogen pollution rules are enforced, many livestock farms will have to get rid of animals or close. REUTERS/Piroschka van de Wouw
