Spectroscopic methods combined with statistics have recently gathered substantial interest in pedological studies. Near-infrared (NIR) spectroscopy has been utilized, for example, reconstructions of the history and transformations Chernozems, although no similar research was conducted based on mid-infrared (MIR). In this paper, relevance MIR tested studies origin/affinity organic matter from ch...

The materials of long-term field experiments carried out in the forest-steppe Ob region Novosibirsk and northern Kuznetsk basin Kemerovo various types crop rotations on leached chernozems were analyzed to assess possibility developing organic farming. most stable rotation relation weeds is a grain-fallow with winter rye, where coefficient productivity decrease an increase infestation by 1 unit ...
