Bio fertilizer contain only living micro-organisms but organic fertilizer mainly contain digested form of plant tissues accompanied by some decomposing micro-organisms

Bio-fertilizer it self explains, fertilizer that contains living organisms that synthesis the atmospheric plant nutrient in the soil or in the plant body, the bio' fertilizers may be in solid or liquid medium and micro organisms are in huge numbers i.e. 10000000 \gm

all above means the nutrients made available to the plants by the help of micro organisms are bio-fertilizers. bio-fertilizers are element specific.

Organic manure is the manure prepared from the animal\plant wastes after properly decomposing the raw material it may contain all necessary plant nutrients in small quantities. these are required in large quqntities. these may the medium for bio-fertilizers.

Bio fertilizers are consists of the helpful micro organisms(bacteria,fungus) Those are increase the soil fertility Bio organisms are fix the atmospheric N, decrease the harmful organism population Organic fertilizers are consist of decaying plant & animal materials Organic fertilizers are increase the water holding capacity of the soil & improve the soil texture

My opinion is there is no conceptual difference between them, because both contain beneficial microorganisms. However, frequently is defined as "biofertilizer" the inoculum of a pure culture of a microbe in adequated amount to improve the growth of a plant. On the other hand, "organic fertilizer" contain consortia of microbes besides organic matter.

I agree with definitions provided by Lakkimsetti K Prasad and Kiran Khandagale. I would like to add that there is a limit beyond which bio-fertilizers cannot supply nutrients like N and P because these are fixed or solubilized by micro-organisms supplied by biofertilizers. On the other hand, organic manures can be supplied in any quantity - depending upon availability and handling capacity. Organic manures can help improve physical, biological and chemical properties of soil.

this is a very interesting question specially in my country all here all confused about the difference. Bio fertilizers should not be named as fertilizers, i suggest the name soil improver would be much better. Organic fertilizers those improve soil organic nutrients and also slowly supply nutrients

Biofertilizer is a substance which contains living microorganisms which, when applied to seed, plant surfaces, or soil, colonizes the rhizosphere or the interior of the plant and promotes growth by increasing the supply or availability of primary nutrients to the host plant. Bio-fertilizers add nutrients through the natural processes of nitrogen fixation, solubilizing phosphorus, and stimulating plant growth through the synthesis of growth-promoting substances. Organic fertilizers are naturally occurring fertilizers (e.g. compost, manure). The majority of nitrogen-supplying organic fertilizers contain insoluble nitrogen and act as a slow-release fertilizer. By their nature, organic fertilizers increase physical and biological nutrient storage mechanisms in soils, mitigating risks of over-fertilization. Organic fertilizer nutrient content, solubility, and nutrient release rates are typically much lower than mineral (inorganic) fertilizer.

Organic fertilizer-fertilizer from organic, natural materials. organic fertilizers include manure, compost, vermicompost, peat, seaweed and guano. Based on the type, of organic fertilizers can be classified into solid organic fertilizer and liquid organic fertilizer. Organic fertilizers contain a complete nutrient. Even contains other organic compounds that are beneficial to plants, such as humic acid, fulvic acid, and other organic compounds.

But biofertilizer can be interpreted as a living organism. Groups of microbes that are often used are the microbes that attach N from the air, which dissolves microbial nutrient (especially P and K), the microbes that stimulate plant growth.

Thanks to all.

Basically I am confused about the comment of Aingkaran Vickneswary and Bijay- Singh . Nitrogen fixation related conversation.

Organic fertilizer contain microbes but cell number are not specified on the other hand bio fertilizer contain specific microbes with measurable cells. Bio fertilizer may use in different purpose to develop both soil and plant.

Bio fertilizer also act some important role against fungal and bacterial disease.

I think bio fertilizer is more efficient than organic fertilizer.

Bio fertilizer is a misnomer for bio-inoculants and introduced as supplementary to chemical/ organic fertilizers during energy crisis of 70s. Organic fertilizers are also known as manures of decomposed plant residues and animal feaces. Both are complimentary in nature for field crops. Now a days refred terms are in review again due to energy crisis and soaring chemical; fertilizer costs in different countries

Dear Mr Noor

Yes, technically there is big difference between bio-fertilizer and organic fertilizer. Bio fertilizers are microbial inoculants consisting of living cells of micro-organism like bacteria, algae and fungi alone or combination which may help in increasing crop productivity. Biological activities are markedly enhanced by microbial interactions in the rhizosphere of plants.

Whereas, organic fertilizers are obtained from animal sources such as animal manure or plant sources like green manure. For example, vermicomposting is a simple biotechnological process of composting, in which certain species of earthworms are used to enhance the process of waste conversion and produce a better end product.

Besides, you can enhance your understanding about microbial bio fertilizer studied by us by viewing our original research article (Asian J. Exp. Biol. Sci. 3(4) 2012: 790-798, www.ajebs.com)

Dear Sir Vijay Singh,

I would like to add some information about the microbes which has great capacity to supply the p available naturally to the plants by mineralizing organic P in soil and by solubilising precipitated phosphates. Some bacterial species have mineralization and solubilisation potential for organic and inorganic phosphorus, respectively. Symbiotic relationship between phosphate solublising bacteria (PSB) and plants is synergistic in nature as bacteria provide soluble phosphate and plants supply root borne carbon compounds (mainly sugars), that can be metabolized for bacterial growth. The PSB solubilise the fixed soil P and applied phosphates resulting in higher crop yields.

Our study also reveals the justification of the above mentioned literatures. Hence, there are number of microbes existing in nature having great capacity to simplify the insoluble complex natural phosphate and supply the sufficient nutrients to the crops and plants. Although, the research in this regard is so limited and there is need of time to explore more and more phosphate solubilising (both solubiliser and mineraliser) microbes for the welfare of our poor farmers. It could also be the eco-friendly options.

Bio fertilizer is addition of fertilizers with innoculants. where as organic is as usual practice of compost knight soil etc.

Bio-fertilizer is a recent terminology as one word for commercial practices. where some are shown for good for horticultural crops etc.

I would also comment that organic fertilizers are made of biowastes in agriculture and livestock , with which a certain amount of feed additives or pesticides may persist , for example copper and zinc in feed and antibiotics in the fecal. In some cases, these material may even pose danger to water quality or crop f\gorwth.

Dear Md. Nasir Ahmad, thanks for your voting our research article published in journal (AJEBS). In addition, I would like to know from your side, whether you & your team have been studied "the impact of microbes in consortia (algae, bacteria, fungi) on the productivity of crops"? If yes, please let me educate with full journal article.

Dr. Amardip Singh

We still have found no opportunity to work on "the impact of microbes in consortia." If we have a chance we will definitely do our study on it & obviously inform you.

Thank you.

The question has been very well answered by all. To be very precise, in bio fertilizers microbes do the job of providing nutrition to the plants in the form N2, P, , Fe, Mn etc but in organic fertilizers, the organic wastes are converted into the usable form by organisms like earthworm ( Vermicompost) . Green manure is also a kind of organic manure. Cow dung, cattle wastes, bio-compost etc can be cited as examples

Organic fertilizers (animal/plant based) also activate natural microflora in the soil and rhizosphere of the plant and are excellent means to enhance natural microbial population. In biofertilizers you add microbe formulation of your choice, but for the establishment and multiplication of the microbe in biofertilizer organic fertilizer is a pre-requisite. Biofertilizer should be used only after ascertaining the microbial count. We find farmers using biofertilizers- but on testing many of them have no live count of the microbe. Best way is to enrich your soil with organics and that to in advance, as organics added give best results after some months.

there are a great difference between biofertilizer and organic fertilizer

1- biofertilizer any fertilizer obtained from a live organism (bacteria, virus ....etc)

2- organic fertilizer any fertilizer contain Nitrogen, Oxygen, Hydrogen and Carbon.

Of course, biofertilizers are more effective and sustain. i think some of synthetic biofertizers like nitrate or phosphate fertilizers are more effective than ancient chemical fertilizer.

All comments are valuable.

I just add that the term generally used is "fertilizer" which is a concept behind providing such essential chemicals or natural substances to the soil for its fertility. Where as

Bio/organic term indicates which active ingredient is used as fertilizer. We use plant growth promoting rhizobacteria as bio-fertilizer and bio-pesticides.

We know the use of organic fertilizer has good results in plants both in agronomy and horticulture, but we have not enough amount s of organic fertilizer especially for use in large cereal or industerial crops like maize, wheat, cotton, sugerbeet, etc. But we can use biofertlizers as a good candidate for aid to organic fertilizers and chemical fertilizers, no insted of them.

Biofertilizers include microbial inoculants like Rhizobium bacteria, PGPR and they have beneficial effect on crop growth and yield especially in legume crops as they have the phenomenon of symbiosis for nitrogen fixation. organic fertilizers are non chemical like vermicomposts, also includes FYM, plant waste like leaf fall etc which are decomposed by organisms for corverting them into useful form for plants

Some biofertilizers are pellets with mycorrhiza fungi or some bacterias as PGPR. In organic fertilizers we can use by example some compost or vermicompost.

I agree Gonzalo. compost and vermicompost fertilizers are good candidate to substitute chemical fertilizers. of course compost that derived from city wasted materials should be exam more and more due to prevent delitrious effects on soils and environment.

Can also be considered liquid biofertilizer which are derived from the fermentation of organic materials, manure and vermicompost, and spore suspensions include mycorrhizal fungi.

How can we know about the effect on soil by using mycorrizal fungi? As I know different concentration may turn to pesticide from fertilizer. If so, will it harmful for Soil?

Organic fertilizers distribute the nutritients more slowly and steadily than mineral fertilizers. Therefore, there is no risk of overfertilization and the soil will not be harmed. Fermofeed produces 100% natural products you should try: https://www.fermofeed.com/products/organic-fertilizers

Sir

Actually we were highlighted on microbes containing fertilizer. Organic fertilizers are used as substrate for microbial growth but we need the clear concept of Bio fertilizer Where the essential microbes are directly inserted or processed with  fertilizer. Those microbes are able to degrade/ absorb/ helpful to use of Minerals and other nutrients of soil . Some Bacillus spp and Aspergilus  spp are able to work as bio fertilizer.

What are the doses of solid biological fertilizer application? How much should be applied solid biofertilizer (with 10 -8 microorganisms in it) to 1 ha field?

Biofertilizer are made up of beneficial microorganisms while organic fertilizers are material made from various agricultural wastes that needs the effect of microorganism for its total conversion from their solid state into decomposed/ soluble material for easy absorption by plants
