Gross nitrogen balance surplus on utilised agricultural area in 2020: 32 kg per hectare

The gross balance surplus of nitrogen on utilised agricultural area in 2020 was 32 kg per hectare on average. The net nitrogen balance (excluding nitrogen emissions to air) in 2020 was -0.2 kg nitrogen per hectare of utilised agricultural area on average. The nitrogen balance is therefore negative for the first time, meaning that more nitrogen has been taken out of the soil by crops than has been put in. In 2018 and 2019, the net balance was around 11 kg per hectare of utilised agricultural area.

74,482 tonnes of nitrogen were applied to soil in 2020 (97% of the 20-year average). Nitrogen removal from soils by crops was 58,948 tonnes (120% of the 20-year average). The gross balance surplus of nitrogen was therefore 15,498 tonnes and the nitrogen released to air was 15,611 tonnes (96% of the 20-year average). The net balance was negative at -113 tonnes.



Gross phosphorus balance on utilised agricultural area in 2020: -0.9 kg per hectare

In 2020, 18.9 kg of phosphorus per hectare was applied to utilised agricultural area on average. 19.8 kg per hectare were removed, which means that the balance deficit was approximately 0.9 kg per hectare. For the first time in the history of independent Slovenia, the phosphorus balance was negative, meaning that more phosphorus was removed from utilised agricultural area than was applied.

In 2020, 9,144 tonnes of phosphorus were applied to land, or 85% of the average of the last 20 years. Crops removed 9,573 tonnes of phosphorus from the soil, or 120% of the average over the last 20 years. The gross phosphorus balance was therefore -429 tonnes.
