English title: Extractability of zinc in cultivated organic soilsTiivistelmä
The AAAc-EDTA extractable Zn content in mould soils (2,3±2,0 mg/ l soil) was not dependent on the total Zn content. In peat soils the extractable Zn content (2,0±1,9 mg/l soil) increased with the increase in total Zn content. The proportion of extractable Zn to the total Zn was less than 8% in Zn deficient mould soils but about 40% in Zn sufficient mould soils. In peat soils the corresponding proportions were 30% and 60%. In mould soils the increases in humus content and acidity caused an increase of AAAc-EDTA extractable Zn. In peat soils extractable Zn content increased with increasing humus content up to 65%. The extractable Zn content was highest between pH values 5,0 and 5,5. Keywords: Extractable zinc, humus content, mould soil, peat soil, pH, total zinc
