Dear K Damodara Chari

I think bio fertilizers just could be a partial alternative for chemical fertilizers. The compelete replacement is far from reality.

The bio fertilizer may replace chemical fertilizer if:

1- The soil contains all essential nutrients (micro ,macro and beneficial nutrients) either in available or unavailable form.

2-All plant species and types have ability to infect with fungi or microorganisms like Rhizobium , Bacillus ...etc.

now we need both bio fertilizer and chemical fertilizer, to increase plant production in world but I thick we need to continue in product friendly chemical fertilizer without side effects.

Dear Dr, K. Damodara Chari ,

Biofertilizers can be the sole complementary candidate in case of legume, only for nitrogen nutrition (N2 fixing biofertilizers). But, in case of exhaustive, intensively grown crops like, cereals this is not possible.

As a result, now the Mineral nutrition specialists are suggesting the INM (Integrated Nutrient Management) system for ensuring proper nutrition while using all possible sources of nutritions in juditial dose and compositions.

You may do a trial with your biofertilizer samples (Consortium experiment) for vegetables or intensively grown fruits to justify its reality. But, the experiment should be conducted in green house rather growth chamber for better understanding.

it will reach in the point of while the crops production at least equal in comparing of the application of biofertilizer vs chemical fertilizer.

this point is really possible to reach, but it will be need application in huge number of biofertilizer.

we need only to prepare biofertilizer in ample so the consideration of economic reason can be omitted from the list of obstacle which many people generally took standing point.

So go ahead in godspeed.

Dear K Damodara Chari I 'm agree with Mohammad Mehdizadeh, that bio fertilizers just could be a partial alternative for chemical fertilizers. The compelete replacement is far from reality.

chemical salt fertilizers could be replaced with rock dust, biological based fertilizers and humic substances but only if N fixing cover crops were also used in rotation for crops like maize and grains that require large nitrogen additions . The two leading crop limiting factors are activated humic compounds and mono silicic acid. Large scale mono culture crops like grasses need nitrogen usually in the form of urea or ammonia. Yes, good farming practices using crop rotations and mined inputs along with bio-fertilizers and utilization of animal wastes would work. This would require major educational efforts and would be resisted by the producers of salt fertilizers and crop chemicals along with the universities supported by grants from the chemical input industry.

We need to understand what biofertilizer is and what are the various groups of biofertilizer.

The above are well documented.

Partial N nutrition of crop plants, some cases increased solubility and availability of PKS may be expected.

Chemicals are not going to be replaced by biofertilizer as long as super GMO's not occupying the role of the chemicals.

It is possible but only if the soil has high amount of organic matter and also depends on the crop planted. There are some crops that are heavy users of nutrients, meaning they consume more nutrients. So, if this plant is planted, the complete use of biofertilizer without chemical fertilizer would lead to a lower yield. Biofertilizers are known to have supplementary functions only.

You are quite right to say that I have observed the same questions from different members sometimes, and I have noticed that some questions are transmitted literally from other sites such as Quirauh. This is a departure from the purpose for which the question was raised for members to benefit all members. What is happening is that some people repeat the same questions in order to increase the recommendations and thus increase the score points.

The application of bio fertilizer reduce the amount of applied inorganic fertilizer and also biofertilizer release available fertilizer in the soil.

For nutrients such as phosphorus, biofertilizers cannot replace them, especially in soils already low in P, but can increase their availability to crops or increase the efficiency with which the applied P fertilizer is utilized by the crops.

Actually the nutrient inputs through biofertilization could hardly completely replace the use of chemical synthesis fertilizers, due to the biological nature its effectiveness is subject to the control of environmental factors that determine the activity of biofertilizing microorganisms, however they are a important contribution to the equilibrium and homeostasis of availability of nutrients. So a plausible strategy is the integrated management of chemical fertilization in addition to biofertilizers, under conditions where they work better. Also optimize the use of chemical fertilization, through the use of bioefectors, in order to make it more efficient and reduce the amount needed to apply, avoiding losses.

I think that it will take a relatively big part , but it couldn't replace it completely because of the slow biological nature of the fertilizers and the high ecopolitical nature of the chemical firmas .

Dear Friend,

One of the main problem of biofertilizers particularly from microbial origin is that they are not so much effective under many conditions!, so, they are far from reality to replace chemical fertilizers.

in many cases they can induce no effect on plants, and this is the main reason behind their very low acceptability among farmers, at least in my country (Iran).

regards

It can be partial replacement of chemical fertilizer but not completly . the main problems of carrier based biofertilizer are short shelf life particularlt in hot arid conditions. liquid based inoculants are effective and less sensitive to changing environment

It is possible if all plants respose to inoculation by mycorrhyzae and all type s of biofertilizers.

Considering the growing population and increase in demand for food supply, it is impossible to replace chemical fertilizer with biofertilizer. However, with help of integrated nutrient management, there is a chance to increase Biofertilizer usage for sustainability and susceptibility

The plant nutrients need and biofertilizers we consider can be used together for some chemical fertilizers supplementation but, not the whole lot of chemical fertilizers to sustain crop production.

I think never

It may causes decrease in application of chemical fertilizers and using Eco-friending bio fertilizer if,

1-Sucess in infection of all plant spices with mycorrhiza.

2- Gen transform between microorganism in order to increase in their efficiency for fixing for example atmosphere nitrogen. Some studies indicated to increase in Phosphorus availability by Rhizobia in additional to nitrogen fixation.\

3- The environmental factor may not suitable for activities of some organisms which are doing as bio fertilizers.

4- Soil chemical and physical properties also may be not suitable for some biofertilizers.

Use of Biofertilizer can reduce the inorganic chemicals but it's not possible to replace it completely. in the scenario of growing population and increase in demand for food supply, it is impossible to replace but with help of integrated nutrient management, there is a chance to increase Biofertilizer usage. https://www.researchgate.net/post/Could-biofertilizer-replace-the-use-of-chemical-fertilizer-in-developing-countries

Biofertilizers are preferred over chemical fertilizers because they are not harmful as they contain organic materials while chemical fertilizers are made up of chemical which are harmful to the consumers. ... For example, anabaena, cyanobacteria and mycorrhiza acts as biofertilizer. https://www.toppr.com/ask/question/why-are-biofertilizers-preferred-over-chemical-fertilizers/

A biofertilizer 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.[1] Biofertilizers add nutrients through the natural processes of nitrogen fixation, solubilizing phosphorus, and stimulating plant growth through the synthesis of growth-promoting substances. The microorganisms in biofertilizers restore the soil's natural nutrient cycle and build soil organic matter. Through the use of biofertilizers, healthy plants can be grown, while enhancing the sustainability and the health of the soil. Biofertilizers can be expected to reduce the use of synthetic fertilizers and pesticides, but they are not yet able to replace their use. Since they play several roles, a preferred scientific term for such beneficial bacteria is "plant-growth promoting rhizobacteria" (PGPR). https://en.m.wikipedia.org/wiki/Biofertilizer

Firstly, I think that it is not possible to eliminate the use of chemical fertilizer by the use of biofertilizer. The population of the world are increasing and the world will need to produce more food, and to do this there is no way without the use of chemical fertilizer. Yes, you are trying to increase the use of biofertilizer but we can not fully depends on it. For the production of organic food, it is mandatory to use biofertilizer.

Chemical fertilizers increase production by they harm the environment.

I don't think that will be possible, because biofertilizers organisms can offer nutrients partially. Second, the world needs rapid solutions for the increasing demands of food by peoples which can not be achieved by using biofertilizers alone.

It may causes decrease in application of chemical fertilizers and using Eco-friending bio fertilizer if,

1-Sucess in infection of all plant spices with mycorrhiza.

2- Gen transform between microorganism in order to increase in their efficiency for fixing for example atmosphere nitrogen. Some studies indicated to increase in Phosphorus availability by Rhizobia in additional to nitrogen fixation.\

3- The environmental factor may not suitable for activities of some organisms which are doing as bio fertilizers.

4- Soil chemical and physical properties also may be not suitable for some biofertilizers.

my research was in this field, so i think we can reduce chemical fertilizer, that help to save the soil and plant,

in additional to the role of bio-fertilizers in decreasing use of chemical fertilizers also using Nono fertilizers causes decrease in using traditional chemical fertilizers.

Integrated approach is viable rather than depending solely upon biofertilizers...

Yes but if the integrated approach consist of bio fertilizers , Nono Fertilizers , combining between them and the best management is necessary for deceasing the use of chemical fertilizers.

In our country it is not possible to stop the use chemical fertilizers. In our lab. we could able to decrease the use of chemical fertilizers only 25%i.e 75% chemical fertilizer and 25% bio fertilizer like vermicompost

It is possible do decrease the use of chemical fertilizers ,and using bio fertilizers but I think we can not able to depend on bio fertilizers only or depending 100% on it.

Dr.Akram you are absolutely correct

thank you Mr. Partha P.C

It is possible and highly beneficial

Hi Dr K. Damodara Chari . I think it should be in all types of organic agriculture . It is more safe than using chemicals in all aspects of agriculture.

Biofertilizer will never replaced the inorganic fertilizers. It can only supplement the inorganic fertilizer. The demand of crops never fulfilled by biofertilizer as it will supply nutrients either through enhancing soil nutrient availability or remains of atmospheric N fixation

Good question. I would have loved to replace chemical fertilizers completely with the biofertilizers or organic fertilozers. However, there are bigger issues in doing so. Without inorganic fertilizers it is difficult to produce sufficient food for the ever-growing population. Instead, one may resort to Good Agriculture Practices (GAP) for judicious use of chemical fertilizer while integrating it with organic manures or biofertilizers. This way we may conserve our land while also promoting biofertilizers. Many thanks.
