Effect of shelterbelt on two kinds of soils on the transformation of organic matter.
The changes of the total nitrogen, average yearly concentration of ammonia, nitrate ions, urease activity, total amount of amino acids in humic acids (HA) and the structure of humic acids were monitored in relation to the effect of shelterbelt as biogeochemical barrier located on a mineral and mineral-organic soil. The transformation of different forms of nitrogen in the soil under shelterbelt was strongly connected with the humification process and the molecular structure of humic acids.
