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 …

The loss of carbon from roots (rhizodeposition) and the consequent proliferation of
microorganisms in the surrounding soil, coupled with the physical presence of a root and …

The functions of iron, manganese, copper, zinc, nickel, molybdenum, boron, and chlorine in
plants are discussed. Iron (Fe) plays a crucial role in redox systems in cells and various …

Improvement of plant iron nutrition as a consequence of metal complexation by humic
substances (HS) extracted from different sources has been widely reported. The presence of …

This new edition provides current information on the nutritional requirements of world crops.
It presents research on the acquisition, accumulation, transport, and functions of chemical …

Vibrational spectroscopy techniques provide a powerful approach to the study of
environmental materials and processes. These multifunctional analytical tools can be used …

Iron is one of the essential elements for a proper plant development. Providing plants with
an accessible form of iron is crucial when it is scant or unavailable in soils. Chemical …

In the last three decades, the concept of soil humic substances has been questioned in two
main directions. Misinterpretations of CP MAS13C NMR spectroscopy led to the conclusion …

In the rhizosphere, exudates from plants and microorganisms as well as stable soil organic
matter influence processes that can control plant growth, microbial infections, and nutrient …

Stimulatory effects of humic substances (HS) on plant growth have been observed and
widely documented. Studies have often shown positive effects on seed germination, root …
