Extract

The study has comprised a detailed analysis of twelve samples of soil, ten of which were samples of typical peat soils, the other two being samples of normal soils. The degree of humification of the organic matter of the samples varied, that in the wet peats being high and low in the dry peats.

Extracts of the soil were obtained by the use of boiling hydrogen peroxide, 20 per cent, hydrochloric acid and 2·5 per cent, caustic potash.

Hydrogen peroxide extracted roughly 70–80 per cent, of the soil nitrogen, 60–70 per cent, of this soluble nitrogen appearing as ammonia through the oxidising effects of the reagent. The nitrogen compounds of wet peats were more easily oxidisable to ammonia.
