摘要：
Eight organic fertilizers and wastes enriched with N-15 labelled urea were stored at 25 degrees C for one year. At the end of the experiment the N-15 recovery rate ranged between 24 and 100%. The distributions of inorganic nitrogen (NH4- and NO3-N) and organic nitrogen (fulvic acids, humic acids and non extractable substances) are ascertained. Between the test materials, there are great differences in incorporation parameters.
