Humic substances (HS) are the most important natural biostimulant of plants. However, relationship between their structure and biological activity in plants is still not well recognized. The objective this paper was to assess influence molecular fractions humic acids (HA) (HA < 30 kDa HA > kDa) on reducing negative effects drought stress soybean (Glycine max (L.) Merr.) seedlings Progres ...

The results of studies five sunflower cultivation variants within the production system ExpressSun™ on ordinary chernozem for 2013-2019 in southeastern European part Russia (the hydrothermal index growing season – hereinafter HTI is 0.70) are presented. It was found that when switching to systemic principle formation, technologies based differentiated soil tillage crop rotation provided an incr...

Sulphur is an essential macroelement that plays important roles in living organisms. The thiol rich sulphur compounds, such as cysteine, γ-Glu-Cys, glutathione and phytochelatins participate in the tolerance mechanisms against cadmium toxicity. Plants, algae, yeasts and most prokaryotes cover their demand for reduced sulphur by reduction of inorganic sulphate. The aim of this study was to inves...

Magnesium and selenium belong to important bioelements. Magnesium is the second most abundant intracellular macroelement, which takes part in the metabolism of carbohydrates, nucleic acids, protein and lipids. Selenium is an essential microelement, whose deficit has been stated in many different pathological states. Much research on safe and effective selenium supplementation has been performed...

Tomato is one of the main and popular vegetable crops not only in Ukraine, but throughout world. According to Food Agricultural Organization (FAO), tomatoes occupy first place world terms cultivated areas among all vegetables — more than 4 million hectares. In about 93,000 hectares 24% total area under are devoted this culture. With advent high-intensity technologies with use drip irrigation sy...

Phosphorus is an essential macroelement in plant growth and the human body, but excessive water enrichment with phosphorus a global threat to quality. To address this problem, development of efficient, affordable adsorbent for use removing large amounts from eutrophic necessary. Food-waste-based adsorbents offer sustainable solution because they utilize waste as valuable resource. This study ex...

Abstract Modeling the seismic response of historical masonry buildings is challenging due to many aleatory and epistemic uncertainties. Additionally, interaction between structural units further complicates predictions behavior unreinforced aggregates found throughout European city centers. This motivated experimental campaign on half-scale, double-leaf stone within SERA (Seismology Earthquake ...
