The article presents the results of research conducted on the
content of some nutrients (Ca, Mg, C, P, K) in plants of different families on
the territory of Amangeldinsky district of Kostanay region. As an object of
research, the leading families were chosen: Poaceae, Chenopodiaceae,
Asteraceae and Brassicaceae, Caryophyllaceae, Liliaceae, Apiaceae,
Ranunculaceae. From 102 species of higher vascular plants growing on the
surveyed territory, 80 species of economically useful ones were studied:
medicinal (34), fodder (34), essential oil (6), food (7), 30 ornamental (30)
and technical value (6). When studying the composition of chemical
elements (macronutrients) of rangeland plants of the study area, it is shown
that the maximum value of chemical element was 0.98%. It is indicated that
nutrient elements mainly enter the plant through the root system from the
soil. Data on the content of Ca, Mg, C, P, K in the root system and aboveground part of the studied plants showing different composition are given.
According to the results of the analysis, the average value of the pastures
showed that the percentage of calcium 0.98%, potassium 3.28%, carbon
46.27%, magnesium 0.17% and phosphorus 0.15% in the plots.
