Biofertilisers
are considered to be an important alternative source of plant nutrition.
They are biologically active products, including bacteria, algae or
fungi, with the ability to provide plants with nutrients. Most
biofertilisers belong to one of two categories: nitrogen fixing and
phosphate solubilising. Nitrogen fixing biofertilisers fix atmospheric
nitrogen into forms which are readily useable by plants. These include
rhizobium, azatobacter, azospirillum, blue green algae (BGA) and azolla.
While rhizobium requires symbiotic association with the root nodules of
legumes to fix nitrogen, others can fix nitrogen independently.
Phosphate solubilising micro-organisms (PSM) secrete organic acids which
enhance the uptake of phosphorus by plants by dissolving rock phosphate
and tricalcium phosphates. PSMs are particularly valuable as they are
not crop specific and can benefit all crops. |
