Biofertilizers are the preparations containing cells of micro- organisms which may be N fixers, P solubilizers, S- oxidisers or organic matter decomposers. In short, they are called as bio inoculants which on supply to plants improve their growth and yield.

Dear Malek al Methayeb,

“A preparation comprising requirements to preserve organisms and deliver them to the target regions to improve their biological activity (or) A consortium of microorganisms provided with suitable medium to keep up their viability for certain period which aids in enhancing the biological activity of the target site”.

In agricultural eco-system, microorganisms have vital role in fixing/ solubilizing/mobilizing/nutrient recycling. These microorganisms occur in soils naturally, but their populations are often scanty. In order to increase the crop yield, the desired microbes from rhizosphere are isolated and artificially cultured in adequate count and mixed with suitable carriers or as they are in suitable combinations (Microbial consortium) by artificial culturing. These are known as biofertilizers or microbial inoculants.

Liquid biofertilizer formulation is the promising and updated technology of the conventional carrier based production technology which inspite of many advantages over the agrochemicals, left a considerable dispute among the farmer community in terms of several reasons major being the viability of the organism.

They are broadly classified into three groups.

1. Nitrogen Fixing Microbes (NFM)

2. Phosphorus Solubilizing Microbes (PSM) and Phosphate Mobilizing Microbes (VAM) and

3. Potash Mobilizing Microbes (Frateuria aurentia)

Among the three groups Phosphorus solubilizing microbes’ usage is to the larger extent in the current agro market. The commercial production of Potash mobilizing bacteria has been developed recently. The authors presently concentrate on solubilization or mobilization of Micronutrients by exploiting the biological activity of microbes like

1. Zinc and Sulphur Solubilizing Bacteria (Thiobacillus spp)

2. Manganese solubilizer (Pencillium citrinum)

Dear Anoop Kumar and Prem, 

Thank you for your detailed answer. But what I mean is, what are the most suitable strains of these microbes which match to physical and chemical conditions of soil in this part of Europe.

So sorry Malek , just missed your response . you will be happy to know , that we have developed a microbial consortium , very specific to Nagpur mandarin as  one of the most commercially grown  mandarin  cultivars . Initially , we observed in declining citrus orchards , most of the trees died , except few. We took some rhizosphere soils from those healthy trees and injected into those declining trees alongside some organic manures so that microbes of healthy trees could multiply , and show their effects on the rejuvenation of those declining trees where we added soils from healthy trees.   To your surprise, within a years time , those declining trees started recuperating . This formed the very basis  of identifying teh source of crop specific rhizocompetent microbes . And , then story went on a few years  , before we came out with a development of mandarin specific microbial consortium...
