Abstract Ammonium nitrate is a hygroscopic and caking product for growing agricultural products. In order to improve the properties of ammonium nitrate, composition calcined crushed cathode material from used lithium ion battery was studied. Since mainly consists lithium, cobalt, manganese nickel, it has been adopted as polymicroelement-containing additive nitrate. Studies have shown that intro...

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...

Copper is a microelement involved in the metabolism of nitrogen compounds plants. Good utilization from soil and fertilizers by plants requires an adequate supply copper. The aim study was to determine effect increasing levels copper (100, 200, 300 mg Cu·kg−1 soil) applied together with various organic (cattle manure, chicken spent mushroom substrate) on content uptake cocksfoot (Dactylis glome...

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 ...

The article presents the materials of studies foliar top dressing with organomineral fertilizers on productivity and quality grain agricultural crops in conditions dark chestnut soils Saratov Left Bank. It is shown that application an organic microelement complex (OMEC) contributes to increase yield compared control at level 0.28 t/ha (winter wheat), 0.07 (chickpeas sunflower) 0.23 (corn). An a...

Microelement contents and metabolism are vitally important for cereal plant growth and development as well as end-use properties. While minerals phytotoxicity harms plants, microelement deficiency also affects human health. Genetic engineering provides a promising way to solve these problems. As plants vary in abilities to uptake, transport, and accumulate minerals, and the key enzymes acting o...

Complexing agents are extensively applied in many fields of industry. They are used to provide effective controlling trace metal ions in cleaning industries, textile, pulp and paper production, water treatment, agriculture, food industries, etc. Recently, the low biodegradability of these ligands and their accumulation in the environment has become a cause for concern. Therefore, replacement of...

iran, with more than 4,400 hectares of cultivated area of ornamental flowers and plants as well as proximity to world markets, bebefits from only a small share in these markets. this party indicates the existence of problems in the production and development of greenhouses that if recognized can be effective in somehow solving those problems. the main objective followed in this study was to ide...
