Drawdown of biophilic elements under winter barley, and maintaining fertility of black soils of Western Ukraine
Climate stabilisation and soil fertility strategies that capture carbon as soil organic matter lag because of ambiguity in stoichiometry, ionomics, and correlations between key chemical components of soil productivity. We analyse the mutual influence of C, N, P, Ca, S, Mg, and K content, N content, microelements, and the yield of winter barley in Luvic Greyzemic Phaeozems of the Ukrainian Western Forest-Steppe. Depletion of biophilic element stoc…
Stoichiometry of arable black soil on the Ukrainian Western forest steppe
Luvic Greyzemic Phaeozems have been farmed for centuries in Western Ukraine. We investigate their stocks of major nutrients and stoichiometry under arable crops receiving conventional NPK fertilisation and an unfertilised control. Total carbon stocks increase only with parallel increases in total N, P, Ca and Mg. Likewise, total N increases along with parallel increases in total Ca and Mg, P and Ca, P and C. Under winter barley, application of th…
Phytoremediation of 137 Cs contaminated sod-podzolic soil in Northern Polissia white sweet clover ( Melilotus albus )
The accident at the Chernobyl nuclear power plant on 26 April 1986 contaminated tracts of Europe with radionuclides. In Ukraine, two million hectares with radiation levels greater than 5.55 × 1011 Bq/km2 were removed from agriculture and 137Cs, with a half-life of 30 years, is still with us. Phytoremediation by vegetation that accumulates toxic elements has been widely applied. White sweet clover (Melilotus albus) accumulates caesium and heavy me…
Amaranth
Amaranth culture is ancient and modern, widespread but mostly small-scale. Its high grain yield is complemented by a unique composition: gluten-free and with a high content of valuable fatty acids. Amaranth produces abundant biomass, the root system improves the soil much more than common cereals and takes up toxic elements. War-torn regions of SE Ukraine can make use of the crop to raise agriculture from a state of crisis to sustainable developm…
Effects of lime and fertiliser on productivity of Albic Retisols
The long-term effects of three levels of liming in combination with NPK fertiliser were studied in a field experiment on sandy Albic Retisols (sod podzolic soils) in Northwest Polissia from 2011 to 2019. Crop yields were recorded and topsoil samples collected annually and analysed for hydrolytic acidity, pH, readily hydrolysable N, labile P, and exchangeable K. The highest levels of plant nutrients were measured in plots receiving the highest dos…
