With a large and growing demand in the market, rapeseed (Brassica napus subsp. napus.) is crop with relatively high requirements for macronutrient fertilization. The aim of experiment was to study effect mineral fertilization different doses nitrogen phosphorus on accumulation microelements vegetative organs grains oilseed rape plants.The carried out long-term experimental fields SCDA Livada. T...

The Borisovsky district of the Belgorod region, located in south-west forest-steppe zone Central Forest Region, was chosen for study. study covered an 11-year period, during which 3 cycles agrochemical soil survey were conducted - 2010, 2016 and 2020. Analyzing use mineral organic fertilizers, increase crop yield indicators noted. Thus, dose fertilizers (up to 1.96 t/ha) 127.2 kg/ha) made it po...

The purpose of the research is to obtain micronutrient fertilizers by applying salts and their complex forms phosphorus obtained in incomplete standards nitric acid or salt mixtures. Central Kyzylkum phosphorites (low-grade P 2 O 5 -12.38%, CaO-43.68%, CO -13.48%, non-enriched -16.38%, CaO-45.93%, -18, 15%, SO 3 -1.86%, thermoconcentrate -27.40%; CaO-54.68%; - 4.52%) were decomposed with at dif...

Foliar fertilization makes it possible to quickly provide plants with essential nutrients, mainly micronutrients, which can significantly improve the quality of yields. The aim this study was evaluate effect foliar fertilizers containing calcium and microelements on yielding fruit highbush blueberry (Vaccinium corymbosum L.). A two-year carried out in western Poland an experimental production p...

Changes in the homeostasis of metals and microelements have been demonstrated in Parkinson's disease, whose etiology includes both a genetic and environmental basis. We studied the difference of microelements in the hair of Parkinson's disease subjects (n = 46) compared with healthy controls (n = 24). Hair was chosen as a representative matrix to measure microelements, since it is a vehicle of ...

Enhancing nutrient uptake and the subsequent elemental transport from the sites of application to sites of utilization is of great importance to the science and practical field application of foliar fertilizers. The aim of this study was to investigate the mobility of various foliar applied zinc (Zn) formulations in sunflower (Helianthus annuus L.) and to evaluate the effects of the addition of...

The review article discusses the main issues of creating and using modern chelated microfertilizers based on trace elements in agricultural production. Issues role microelements vital activity living organisms methods overcoming lack micro­elements plants are highlighted. An overview coordination compounds 3d-metals (Fe, Mn, Zn, Cu, Co, Ni, Mo) with different classes complexons, features their ...

Roselle (Hibiscus sabdariffa L.) is one of the most important medicinal crops in many parts of the world. In this study, the effects of microelements, antioxidants, and bioagents on Fusarium oxysporum, F. solani, and Macrophomina phaseolina, the causal pathogens of root rot and wilt diseases in roselle, were examined under field conditions. Preliminary studies were carried out in vitro in order...
