This study compares the effectiveness of multi-micronutrient formulations containing iron (Fe), manganese (Mn), and zinc (Zn) with traditional (EDTA, DTPA, HEEDTA, and EDDHAm) or novel chelates (o,p-EDDHA, S,S-EDDS, and IDHA) and natural complexing agents (gluconate and lignosulfonate). The stability and reactivity of the formulations were studied on batch experiments with calcareous soil and b...

Quantification of the Nitrogen (N)-supplying capacity of organic manures provides an important insight into more effective N management practices. The aims of this study were to determine the potential N mineralization of cow manure (CM), poultry manure (PM), urea fertilizer (UF) and the combined use of cow manure + urea fertilizer (CM + UF) for silage maize (Zea mays L.) in a calcareous so...

With the global population predicted to grow by at least 25% by the year 2050, the sustainable production of nutritious foods will be necessary for human health and the environment. Iron (Fe) is an essential nutrient for both plants and humans. Fe is poorly soluble, especially at high pH levels, at which it is difficult for living organisms to accumulate sufficient Fe. In plants, Fe deficiency ...

Pedogenesis and clay mineralogy of soils and rock samples were studied in a transect of calcareous, gypsiferous, saline soils and sediments of Bakhtegan lake bank in southern Iran. The main objectives of study were to determine the occurrence of clay minerals and factors controlling their distribution pattern and relative abundance in soils and parent materials. The soil parent material is high...

Calcareous soils are known for their alkaline pH-promoting insoluble forms of certain nutrients, including phosphorus (P). Rhizosphere acidification is one the main physiological mechanisms mobilization by plants. However, specific and genotypic differences in response to P deficiency often observed, giving some genotypes particular tolerance abilities. This genetic potential gives us a new opp...
