Soil organic matter has been extensively examined because of its importance for soil fertility and productivity, and as a critical component in agricultural production systems. Furthermore, its importance for establishing favorable physical condition

Phenolic acids have been implicated in the process of allelopathy and are, therefore, of interest in plant management as a basis for new herbicide structures. The potential bioavailability of phenolic acids is controlled by sorption–desorption proc

Phenolic compounds originating from plant residue decomposition or microbial metabolism form humic-like polymers in the presence of various phenoloxidases or metal oxides. Enzyme-mediated reactions were reported to result in the decarboxylation or de

Soil-bound residues of the fungicide cyprodinil (4-cyclopropyl-6-methyl-2-phenylaminopyrimidine), which was labeled with 13C and 14C either in the phenyl ring or the pyrimidyl ring, were analyzed by a silylation procedure and 13C-NMR spectroscopy. Af

13C-NMR spectroscopy was applied to the evaluation of soil-bound residues of the fungicide cyprodinil (4-cyclopropyl- 6-methyl-2-phenylaminopyrimidine). A mixture of the 13C- and 14C-labeled fungicide was used to obtain structural information as well

The fungicide cyprodinil [4-cyclopropyl-6-methyl-2-(phenylamino)pyrimidine] labeled with 14C in either the phenyl or the pyrimidyl ring was incubated with four different soils under various conditions to evaluate the formation of bound residues and t

In continuation of former measurements about gaseous denitrification losses, these losses together with those by nitrate leaching were measured by different methods in a field cropped during two years by wheat. Furthermore, N-uptake by the plants of

Humus properties in various Ap horizons from field plots, that have been cultivated in long-term experiments under different management conditions, were investigated by pyrolysis-field ionization mass spectrometry (Py-FIMS) and 13C-NMR spectroscopy.
