Abstract: The experiment "Influence of mineral fertilizers of different form on the leaching of biogenic elements and nitrogen regime in sandy loam soils" was carried out in lysimeter facilities of Voke Branch of the Lithuanian Research Centre for Agriculture and Forestry (LRCAF) in 2008 – 2011. The aim of the experiment – to assess the effect of solid and liquid fertilizers and their impact on surface water contamination with biogenic elements. Precipitation filtration in fertilized soil was by 11.9-14.7 % lower than in untreated soil. Granular PK fertilizer induced the migration of calcium and potassium, and the concentration of these elements in lysimeter leachate increased compared to soil treated with liquid fertilizer Lyderis 9-9-9. However, the use of Lyderis 9-9-9 activated phosphorus leaching, and its concentration in the leachate was higher than in soil treated with granular fertilizers.
