The article presents results of studying total content
of titanium in both not fertilized and systematically
fertilized black leached soil. Science-based system of
fertilizer crop rotation allows solving problems of
sufficient balance of nutrients in the system of "soilplant-fertilizer",
increasing the quantity and
improving the quality of the crop. At the same time,
their application is active influence on the natural
environment. In the soil, there is an input of a large
set of chemical elements come along with fertilizers.
In addition, due to their physiological pH or
alkalinity, fertilizers are capable to affect the physical
and chemical properties of the soil. The use of
mineral fertilizers in scientifically based doses on the
fields of crop rotation for 33 years virtually has no
impact on the content of titanium in leached
Chernozem. In the arable layer its number increased
only by 2.1 %, and in subsurface - it is the same as in
the crop without fertilizer. Enrichment of topsoil with
titanium is due to desilication of rocks during
weathering. Due to the low solubility of titanium
minerals, they remain in the place longer, and
therefore, the content of the element in the soil
increases. As you know, fertilizers applied to the
fields of crop rotation, increase the intensity of the
biological cycle of substances and thereby enhance
the process of destruction of the parent rocks
