Urvas L. Rikki viljellyissä eloperäisissä maissa.

Tiivistelmä

In mould soils the concentration of acid ammonium acetate extractable sulphur (SAAAc) was 33 mg/l on average and total sulphur (Stot) was 833 mg/l. Corresponding contents in peat soils were 45 and 1209 mg/l, respectively. Average extractability of sulphur was 4.2 % in mould soils and 3.7 % in peat soils. In both soil types the extractability was highest when pH was lowest. Increasing humus contents decreased slightly the extractability of sulphur. Key words: humus, mould soil, peat soil, pH, extractable and total sulphur L. Urvas, Agricultural Research Centre of Finland, Institute of Soils and Environment, FIN-3J600 Jokioinen, Finland
