Bio fertiliser contain living microorganisms which, when applied to seeds, plant surfaces, or soil, colonise the rhizosphere or the plant roots and promotes growth by increasing the supply or availability of primary nutrients to the host plant.
Bio Fertilisers increase ‘plant efficiency’ enhancing plant health, resistance to pathogens and decreasing the need for chemical fertilisers and pesticides.
Undisturbed soils are full of naturally occurring beneficial soil microorganisms including mycorrhizal fungi and plant growth promoting rhizobacteria (PGPR). As well as supporting the plants they also support a healthy soil community of living organisms including protozoa, nematodes, arthropods, insects and earthworms as well as other fungi and bacteria. These living organisms play critical roles in balancing the chemistry, physics as well as the biology elements of a healthy soil.
Many common practices, in conventional farming, can disrupts the soil microbiota, re-introducing these plant growth promoters in areas, where they have been lost, will speed up the recovery of soil biodiversity and soil fertility.
