RISSACHCSO

Calculating GNB

Each of the 7 regions of Hungary According to OECD methodology HCSO agricultural databases (regional data), RISSAC coefficients (country

level) No regional coefficients Annual and cumulated balances

Inorganic- enterprises: quantity of active ingredients

(NPK) known- private holdings: quantity of active

ingredients only in 2002 was known- Quantity of mineral NP per hectare

II. Output

Ratio of main- and by products;

Handling of by-products- 70% of cereal straw is

removed from the field- 0% of corn and sunflower

stalk is removed Nutrient level of the soil Highest yield in 2001, 2004

IV.Problems

Application rate of inorganic NP on different crops - within the advisory scheme - minimal respond No data on bought feedingstuff - surface balance No data on urban compost - negligible

Summary

Balances were mostly determined by output Balances alone are not sufficient to evaluate environmental

effects of agriculture - soil supply status - groundwater nitrate content Losses during storage of mineral fertilizers, and aging of

manure (~10-20%) Manure appliation (only 80% of the total quantity) Losses in the process of wet and dry deposition (~20%) N content of manure can not be utilized by 100% by crops

(~50-70%)
