The dynamics and transformations of micronutrients (Zn, Cu, Fe, Mn, B and Mo) in soils, are
governed by various factors like pH, EC, soil organic matter etc. Soil organic matter (SOM) is …

Purpose The rationale of this paper is to review the state of the art regarding the biotic and
abiotic reactions that can influence Fe availability in soils. In soil, the management-induced …

Improvement of plant iron nutrition as a consequence of metal complexation by humic

Poor iron (F e) availability in soil represents one of the most important limiting factors of
agricultural production and is closely linked to physical, chemical and biological processes …

Goethite, hematite, ferrihydrite, and other iron oxides bind through various sorption reactions
with humic substances (HS) in soils creating nano-, micro-, and macro-aggregates with a …

Humic acids (HA) have a colloidal character whose size and negative charge are strictly
dependent on surface functional groups. They are able to complex large amount of poorly …

Iron deficiency is a frequent problem for many crops, particularly in calcareous soils and iron
humates are commonly applied in the Mediterranean basin in spite of their lesser efficiency …

Micronutrient malnutrition is one of the major causes of human disorders in the developing
