The beneficial effect of organic matter on Fe chlorosis prevention
depends on the direct Fe chelating ability of the humic and fulvic
acids and the biostimulation exerted by organic components on
both the soil microbial activities and the root growth (Shenker and
Chen, 2005). In particular, previous studies showed that plant roots
development was positively influenced by the presence of particles
of added organic materials, which have also the ability to attract
roots towards them, increasing mucigel excretion (Trinchera et al.,
2010) and acidic root exudates (Oburger et al., 2009), so to be able
to solubilize nutrients from GMF + DVV mixture.
