Table 2.

Breakdown of municipalities with surplus and deficits of nutrients in relation to their share of arable land, crop nutrient needs, and nutrients in excreta at the national level.

The net balance is the difference between crop needs and total nutrients in excreta, which is also expressed as a percentage of crop nutrient needs. These balances do not include the synthetic fertilizer supply which was only available at national scale.
