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 …

Modern agriculture systems are copiously dependent on agrochemicals such as chemical
fertilizers and pesticides intended to increase crop production and yield. The indiscriminate …

In the rhizosphere, exudates from plants and microorganisms as well as stable soil organic

Humic substances (HS) are powerful natural plant biostimulants. However, there is still a
lack of knowledge about the relationship between their structure and bioactivity in plants. We …

Although iron (Fe) needs by fruit trees are relatively low, Fe deficiency represents the main
constraint for successful cultivation of fruit tree crops in calcareous and alkaline soils …

Calcareous soils are known for their nutritional disorders due to the insoluble form of iron
that limits free Fe availability for crops. However, it is well established that organic …

The aim of this study was to evaluate the effectiveness of soil applied compost in preventing
Fe chlorosis of pear trees. The effect of the treatment was evaluated in field conditions on …

It is well known that in the rhizosphere soluble Fe sources available for plants are mainly a
mixture of complexes between the micronutrient and organic ligands such as organic acids …

To investigate the role of natural humic substances on plant cell phosphate level and
metabolism, tobacco BY-2 suspension cell cultures were grown in the presence of humic …
