Resources and fractional composition of humus in soils of convent gardens of Cracow

摘要

Investigations were conducted to determine the impact of urban environment and cultivation on the content and fractional composition of humus in anthropogenically transformed soils of selected convent gardens in Cracow. Convent gardens in Cracow, mostly utilised as vegetable gardens, are located in densely built up city areas. On the basis of conducted research, it was established that hortisols of studied gardens are characterised by a high abundance of good quality humus. Humines and humic acids prevail over fulvic acids in humus compounds of these soils. Value of C:N ratio evidences advanced mineralisation of organic matter and good biological activity of soil.
