Abstract

PREVIOUSLY, Mack and Barber1 found that phosphorus fractions in soils are affected by freezing. They showed that more water-soluble phosphorus was released from soil which had been previously frozen at − 20.5° C. than from one incubated at 2.7° C. To examine the effect of temperature (from + 24 down to − 196° C.) on nitrate release a brown forest soil (Grenville silt loam) having an organic matter content of 5.6 per cent was selected. The soil was sampled in the field and stored in a moist state in a controlled temperature room at + 1° C. until required for three experiments.
