In laboratory experiments it was stated, that during washing out caused by water, in three different soils, there were more nitrates than ammonia nitrate. The inverse effect was observed when potassium chloride solution was applied and when preliminary soil liming was used (more ammonium nitrate). The largest losses of nitrogen compounds were found for soils with the lowest content of humus and mineral colloids
