Abstract

The paper considers the influence of different covers, such as crop residues, soil crust, etc. on the remote determination of humus content in soils of agricultural land. It is shown that in laboratory conditions with dry soil there is a close relationship between the humus content and spectral reflective properties. When soil is moistened, the spectral brightness coefficient decreases, which gives a false idea of a higher humus content. The presence of naturally occurring crop residues in the form of straw, on the contrary, gives an idea of a lower content. The formation of seasonal thin soil crusts on the surface of arable soils with different humus content is even more difficult for remote determination of humus. In order to identify the impact of different covers on remote definition of humus, the complex of laboratory and field observations which showed that in vivo continuously there are processes as a result of which the same soil on the spectral reflective properties can be carried on the maintenance of a humus to various taxonomical groups was carried out.
