After 2005, the gross nitrogen budget ranged between 32 and 69 kg per hectare of agricultural land with an indistinct downward trend. On average over the last five-year period, the target value (less than 50.4 kg per ha) was achieved. In 2022, the nitrogen balance surplus rose sharply compared to the previous year (from 46.2 to 69.1 kg per ha). The target value (less than 49.4 kg per ha) was therefore not achieved. The increase in the surplus is attributed to the drought, which caused a decrease in the nitrogen uptake by agricultural plants.
