Changes of nitrogen content in humic compounds of muck soils formed under different hydrological conditions
1986
Drozd, J. (Akademia Rolnicza, Wroclaw (Poland))
Humus compounds present in muck soils vary in contents of carbon and nitrogen which manifests itself in different C to N rations. Small-molecule humus compounds showed the lowest C to N ratio. The C to N ratio in fulvic acids and in the residue after extraction was found to increase with increasing soil moisture
