Technical-technological aspects of using machines and tools for new technologies in plant production

Faculty of Agriculture, Belgrade-Zemun (1,2,3,4,5,6,7)

Abstract:

Agricultural production is complex process and it depends of various factors which can be controlled. Many of them can be improved by using of various means which are not friendly for environment and health of people. It is necessary to apply only those measures which can maintain and improve physical - mechanical, technological and microbiological properties of soil and also the nutritive potential of soil but will not be harmful for environment. The other part of this story demands decrease of energy necessary in the process of soil preparation.

Effect of land use on group and fractional composition of humus in rendzina soils in Serbia

Department for Pedology and Geology, Faculty of Agriculture, Belgrade-Zemun (1,2)
Center for Multidisciplinary Studies, Belgrade (3)

Abstract:

The effect of land use on group and fractional composition of humus was examined in 13 rendzina profiles under forests, 12 profiles under grassland and 8 profiles under arable fields in different parts of Serbia where rendzinas are typically found. The difference regarding land use of rendzina soils (depending on cultural practices or absence of any, and different amounts and quality of plant residues) under forest, grassland or arable fields had a highly significant statistical effect on humus group composition and the fractional composition of humic and fulvic acids.
