There is absolutely no doubt , whatsoever about the better water- and nutrient-use-efficiency with fertigation over conventionally used method of fertilizer application , regardless of soils and crops. In addition , crop quality and soil health -related issues are supposedly consider better , but many question about the efficacy of fertigation regarding the long term effect on soil health-related issues , simply non the premise that this method of fertilizer application again another form of chemigation, including the use of water soluble fertilizers . In this background , propose the following set of question for your redressal , dear colleagues and friends, so that this important issues can be discussed in a most befitting manner;
* What should be the framework of bio-fertigation?
* What kind of crops could be most suitable through bio-fertigation?
* Can we meet complete crop nutrient requirement through bio-fertigation/
* Do you expect better nutrient-use-efficiency through bio-fertigation?
* What could be the long term effect of bio-fertigation on carrying capacity of soil with respect to annual versus perennial field crops?
Thanks n Regards
Dear Anoop take a look on pending PDF i think it was useful for your interest:

Bio fertilizers contain live beneficial microorganisms that provide nutrients and other benefits to crops. At present, bio fertilizers can be found in solid and liquid forms. Liquid bio fertilizer can be one of the alternatives to chemical fertilizers and pesticides. Liquid bio fertilizer is produced through culturing of microorganisms that are known to have specific capabilities in helping plant growth. However, application of bio fertilizers in the form of solution is more tedious than that of solid bio fertilizers, which can be applied directly to plants, whereas the liquid form requires several stages of preparation before it can be applied to crops.
BENEFITS FROM USING BIOFERTILIZERS
Increase crop yield by 20-37%.
Stimulate plant growth.
Activate the soil biologically.
Restore natural soil fertility.
Provide protection against drought and some soil borne diseases.
Solublize Phosphorus Potash in the soil and make them available to the plants along with Nitrogen and other micronutrients like Zinc and others.
HOW COULD ONE GET GOOD RESPONSE TO BIOFERTILIZERS APPLICATION?
Biofertilizers product must contain good effective strain in appropriate population and should be free from contaminating microorganisms.
Select right Biofertilizers and use before expiry date.
Use suggested method of application and apply at appropriate time as per the information provided on the label.
WHAT PRECAUTIONS ONE SHOULD TAKE FOR USING BIOFERTILIZERS?
1. Biofertilizers packets need to be stored in cool and dry place away from direct sunlight and heat.
2. Other chemicals should not be mixed with the Biofertilizers.
3. While purchasing one should ensure that each packet is provided with necessary information like name of the product, name of the crop for which intended, name and address of the manufacturer, date of manufacture, date of expiry, batch number and instructions for use.
4. The packet has to be used before its expiry, only for the specified crop and by the recommended method of application.
5. Biofertilizers are live product and require care in the storage.
6. It is important to use Biofertilizers along with chemical fertilizers and organic manures.
7. Biofertilizers are not replacement of fertilizers during the first three or four years but can supplement plant nutrient requirements sufficiently. After about four years Biofertilizers can replace chemical fertilizers. However in Organic Farming Biofertilizers replace chemical fertilizers altogether.
Article Biofertilizers and Eco-friendly approach
I would like to know the answer to this part of question " What kind of crops could be most suitable through bio-fertigation?"
I side with Nahel. Curious to know the suitable crops that can be out on thus excellent fertilization model!
We intend to supply PGPRs through micro-irrigation . Any PGPRs to be applied in any growing medium have to fight it out for their survival , it will not multiply in an uncontrollable manner ..
Efficient use of applied nutrients is necessary for optimum growth and yield. But biofertigation alone can not ensure availability of all nutrients, because there are several external factors affecting it. The concentration and uptake of nutrients in crops varies with age of crop, season, plant parts, stage of crop and cultivars. During the vegetative stage, plant absorbs nutrients vigorously to build up plant frame work and excess nutrients are stored within the plant and translocated to fruits for further development. Do we have biofertigation standards for different crops.
Dear Dr. Anoop, you loaded question on new area, where we need to have attention. Do you have any idea about such commercial biofertigation products in the market? Do we have set mechanism for its regulation in the country? I hope you will be in position to throw light on these connected questions.
A biofertilizer is a substance which contains living micro-organisms which, when applied to seeds, plant surfaces, or soil, colonize the rhizosphere or the interior of the plant and promotes growth by increasing the supply or availability of primary nutrients to the host plant.For edible crops, fertilizer is usually applied in the spring and mixed into the garden soil before planting. Bio-ertigation, the application of organic fertilizers with the irrigation water, allows applying small amounts of fertilizer in each fertigation event, that contributes to high flexibility in fertigation frequency. Both nitrogenous and phosphatic biofertilizers are to be used to get the best results. It is important to use biofertilizers along with chemical fertilizers and organic manures. Biofertilizers are not replacement of fertilizers but can supplement plant nutrient requirements. Bio-fertilizers are live microorganisms that come from bacteria, fungi, or algae. Their approach is unique and may be used alone or in combination. Bio-fertilizers fix nitrogen and legume crops in the soil and make them available to plants through their roots.
