The use of rhizosphere microorganisms for plant fertilization becomes the ideal tool for the agricultor who wants more sustainable practices. Biofertilizers based on fungi and bacteria act at ground level by acting as miniature nutrient plants. They fix atmospheric nitrogen (as does Rizobium in legumes), solubilize phosphorus, mobilize potassium and other microelements (iron, manganese, zinc, etc.). Similarly, scientific studies prove that the use of bacteria is beneficial for soils and crops.
RHIZOBACTERIES: The PGPR rhizobacteria of the FullSoil® technology colonize the root and its zone of influence (rhizospheric soil). Beneficial rhizobacteria, commonly known by the acronym PGPR (Plant Growth Promoting Rhizobacteria), fulfill key functions for the plant such as:
Stimulation of seed germination and rooting.
Improvement of the soil structure
All this with the benefits of mycorrhizae, gives birth to FullSoil® Technology
The mechanisms of action of PGPR can be classified as Direct and Indirect.
1) DIRECT MECHANISMS: Bacteria provide certain compounds to the plant or facilitate the assimilation of soluble nutrients from the soil.
2) INDIRECT MECHANISMS: Bacteria also produce substances that can mobilize amino acids, siderophores or organic acids that release phosphorus, iron and / or aluminum.
