Supplying a sufficient amount of available iron (Fe) for plant growth in hydroponic nutrient solutions is a great challenge. The chelators commonly used to supply Fe in nutrient solutions have several disadvantages and may negatively affect plant growth. In this research study we have synthesized certain Fe-amino acid chelates, including Fe-arginine(More)
Amino acids (AA) as metal complexing agents have the ability to form relatively stable complexes with zinc (Zn) and thereby increase its availability for plants. In this study, the complexes of Zn(II), [Zn(L–L′)2] [where L–L′ = monoanion of arginine (Arg), glycine (Gly), glutamine (Gln), histidine (His), and methionine (Met)], were synthesized and(More)
The use of sewage sludge in agricultural soils can improve soil physical and chemical properties and soil fertility by increasing organic materials; however, the presence of heavy metals in sewage sludge is a significant problem for the quality of agricultural products and the environment. Most heavy metals, due to their inactive nature, are stable and can(More)
Supplying a sufficient amount of available Fe for plant growth in hydroponic nutrient solutions is a great challenge. The chelators commonly used to supply Fe in nutrient solutions have several disadvantages and may negatively affect plant growth. In this research study we have synthesized certain Iron by 1,10-phenanthroline [(Fe(phen)3)(Cl2·L4)] (L =(More)
The objective of this study was to extract cellulose nanofibrils (CNFs) from Linter dissolving pulp through a simple and environmentally friendly physical method of refining pretreatment coupled with ultrafine grinder. The morphology, structure and properties of the Linter pulp and obtained NFCs were investigated using Optical Microscopy (OM), electron(More)
