Organic is best option

However sometimes feeding huge population becomes bigger challenge than to get quality food as is precedent in most of Asian developing countries.

Here one can not think to go in organic mode despite its advantages as filling bellies is most important.

From sustainable point too , organic mode is the best option.

So it is situation which may dictate to adopt among both options.

I would always advocate to use combination of the two which fitz well with climate smart agriculture....

For today's and tommorrows condition combined use of both forms of fertilizers will help to survive and feed growing population. If we want higher productivity then go for inorganic fertilizers and if quality is concerned then organic resources are better.

There is a whole range of organic fertilizers, compost, compost enriched with bacteria, fishmeal, etc. and the value of each compost differs depending on its composition. In addition a compost includes all elements nitrogen phosphorus potash, trace elements and especially organic matter that is not found in chemical fertilizers. So in terms of productivity, it is necessary to calculate well the needs and to choose the organic fertilizer that is necessary for this or that culture.

On equivalent basis, organic manures and composts fall much short to chemical fertilizers. I still maintain , as long as fertilization is balanced addressing to prevailing soil fertility constraints , regardless of source of nutrient supply, both sources are equally effective.But the bigger question, where is the raw materials for compost. ..

This depend on the purpose from the addition if it was for recovery of nutrient deficiency chemical fertilizers must be used , but for slow released fertilization organic sources of fertilizers are preferred.

Thank you all for your valuable answers and feedback

Thank you Dr. Prashant Balasaheb Pawar for your feed back, do you mean that if we use organic fertilizer the productivity will decrease??

both may be good, if fulfill our requirement, good quality with good yield

Thank you Dr. Anoop Kumar Srivastav for your feed back, you are asking about the source of compost , it is from plant and animal residue

Thanks Masnat .I was saying , if you evaluate crop response on nutrient equivalent basis using organic manures( any source) and inorganic fertilizers(mainly N-equivalent is used), there might not be so distinct difference. In this regard , we need to stratigise the comparison between the two divergent nutrient sources ...

Thank you Dr. Anoop Kumar Srivastava , but I want to know if we can reduce the use of chemical fertilizers to reduce the cost of producing and for the environmental issues, is it enough to add the compost alone which is manufactured from plant and animal residues

Integration of the both is the better option

In terms of productivity, inorganic/ chemical fertilisers are better than the organic fertilisers. In terms of pollution, organic fertilisers are better than inorganic fertilisers, organic fertilisers are ecofriendly

in continuation with my earlier answer.

Organic fertiliser are ecofriendly

It depends on your goal. If you were an organic farmer, use organic fertilisers (manure, compost, etc.), but in conventional agriculture, keep using mineral fertilisers. The latter are salts, ready to use, the former needs to degraded before used by plants. With rational use, environmental damages caused by mineral fertilisers could be minimum.

The soil test will show what is needed. Chemical fertilizers are quicker, and more efficient when applied properly. Organic fertilizers have the slow release, which depending on the deficiencies, may be best. It really depends on the cost of both in terms of price and application methods. The main thing to remember is without proper soil PH, either is just a waste of money.

Its a good point Masnat , whete is such a vast quantity of crop / farm residuesto be subjected to composting??. Will you do it at the cost of fodders to be given to livestocks??. Cost of production also need to be minimised...there is absolutel no doubt about ecofriendness of organic composts. Therefore , it will be more advisable to use them conjointly...called climate smart approach..

Integration of both type will be a good choice. organic will add other plant essential nutrients too which is a plus point. Also, organic like crop residues will help to control erosion and maintain moisture also, which is crucial, especially in drylands. and since crop residues can not supply enough nutrients on time of plant need, integration of both would be good choice, I think.this will be beneficial in the long term.

Thank you Dr. Anoop Kumar Srivastava for your feed back, you are asking about the cost, the farmer will buy the compost in prices less than the chemical fertilizer, but I am wondering if the farmer uses organic fertilizer, the productivity will be less???? as mentioned by researchers

Many researchers suspect the lower productivity with organic fertilizers compared to inorganic fertilizers , especially initial years...

In case of environmental pollution ,decreasing of chemical fertilizers use to lowest degree is a best choice .The alternative was the use of Eco-friendly fertilizers ( organic and bio fertilizers) ,which helped in keeping soil health beside providing plants with required nutrients.

Famous sub-content saying: In dual side hard conditions

''One side is flame and other side is sea. Where run for safety!''

Organic fertilizers are better for soil and environmental sustainability as well as human heath, however, they could no help to feed the whole world and full fill the food demand which is high due to increased population. Read below i have explained clearly, Decide yourself.

Ans: Chemical fertilizers vs Organic fertilizers

Chemical fertilizers (Advantages:)

Rich in nutrients

High content of nutrient, Like NPK

Specifically nutrient can be supplied, Like N or P, what you want.

Always ready for quick supply of nutrients

Equal distribution

Fast release of special nutrient which are always required to crop like NPK.

Significantly increase yield per unit area.

Cheap, easily available.

Disadvantages"

Environmental hazards

High acid content. soil fertility damage over a long time use

Burn out the soil

Toxic Food

Organic fertilizers (Advantages)

Enhance soil by addition of natural nutrients

Improve soil organice matter

Improves soil structure

Enhance water holding capacity

Slow and consistent release of nutrients

Reduces risk erosion

Reduces risk erosion

No toxic Food

Disadvantages"

Slow release of nutrient

Availability issues

Expansive

Less content of major nutrients, like NPK

Specifically nutrient can not be supplied, Like N or P, what you want.

Always not ready for quick supply of nutrients

Not equal distribution

Not increase yield per unit area to achieve high yield.

Kind regards, SJ

Thank you so much Dr. S J Leghari for this valuable answer, and you are right : the increase demand for food allover the world make us under a stress, that we we have to increase the productivity, but at the same time we want to save the environment and water, as you have mentioned: In dual side hard conditions.

Yes Dear, exactly, with this concern, i was suggested organic-chemical fertilizer theory and a little practical work during 2015. In my publications, you can find it. Influence of sustainable source of nutrient on

growth and yield of sunflower (Helianthus annus L.).

Site specific conditions is best dictator for mode to be chosen.

I would say booth of them have their own advantages and disadvantages. What we get from chemical may not be obtained from the organic fertilizer and the opposite is true. Simple example, chemical fertilizers release the nutrients fast while organic do it slow. Crops respond fast to chemical fertilizes than to organic. The productivity of crops in response to chemical fertilizeres is higher than to organic. However the crop grown with the supplement of organic fertilizers have better quality produces. Besides, unlike the chemical, organic fertilizers are environmental friendly and safe. Organic fertilizers have also a positive impact on the phsico-chemical proporty of soil which will have a postive enfluence on crop productivity and produce quality.

Organic fertilizers don't must be considered only fertilizers, but enhancers of biota and biological process in soil.

Thank you Dr. Daniel Zeru for your valuable answer, as I have understood from many researchers, we cannot have the high productivity if we use only compost, and if we want to increase the productivity , we have to use chemical fertilizers.

Whether any one has studied , how long residual effect of organic versus mineral fertilizers last , especially in fruit crops..??

Compost is the better option

As use of organic manures improves the soil properties therefore their response on crops lost long compared to urea, muriate of potash and Phosphatic fertilizers application. Mainly nitrogenous fertilizers have few days effect crops.

What should be the basic premise of prefering organic fertilizers over mineral fertilizers..?? We canot outrightly replace mineral fertilizers with organic fertilizers...that should always be kept in mind, who believe in approached advocating either of the modes feeding crops, though , i always prefer to use combination of the two to prolong the efficiency of both the sources of nutrients...

I think chemical fertilizer should be needed for high productivity. But, I think the environmental friendly fertilizer is the biofertilizer (EM compost). Actually my one of research based on production of biofertilizer from phosphate solubilizing bacteria. These type of fertilizers gives lot of benifits to plants for their proper growth.

Each have their beneficial effects and, shortcomings as well. The smart way is to use them in combination, at the right time and proportion according to the local climate and conditions.

Intensive use of chemical fertilizers (for higher productivity) deteriorates the quality of soil due to continuous uptake of nutrients by crop plants. The application of organic fertilizers in the form of decomposed plant and animal residue, not only adds organic matter to soil but also the diverse microbial flora responsible for nutrient transformation. This improves the quality of soil in terms of fertility and productivity. Sole application of organic fertilizer does not improve the biological health of soil after 3 years as indicated by the enzyme activities profile of soil. Thus, integrated use of chemical fertilizers and organic fertilizer is more beneficial and economical.

I agree with the above answers. In my view Integrated approach of Organic and inorganic sources could be best for achieving higher crop yields without deteriorating soil parameters.

This is a function of environmental quality, food quality, adequate food production. We have to balance these factor for sustainable agriculture. Continous usage of chemical fertiliser may meet adequate food in short term but in longterm there will be environment and food quality problems. In contrast organic fertilizers can be environmentally friendly and may enable better quality food but fail to meet adequate food production. The amounts of organic fertilizers are lacking to meet wast usage of them. Therefore best way is to use both fertizer types on crop and environmental condition based to meet food requirement.

Organic production is not merely application of composts. It address with use of composts, bio-enhancers, bio-pesticides, crop rotation, green manuring, trap, cover crops, mix cropping/farming, integration of livestock, fishery, poultry and so fourth. Use of mineral fertilizers and pesticides increases cost of production as well as pollute the agro-ecosystem. If we see the recovery of nutrients from mineral fertilizers is pathetic. That of nutrients can easily be met with agri inputs without cost and pollution.

Organic fertilizer benefits and uses and therefore also damage to mineral fertilizers benefits and damage related to the crop and the type of agriculture and so on in the horticultural crops prefer organic fertilizers as well as the type and quality of the product related to organic fertilizer, in contrast, grain crops are used for mineral fertilizers because it must have a high production is not available organic fertilizers

Thank you Dr. Waqas Al-Joboory for your answer, do you mean that for horticultural crops, we can use organic fertilizer, and the productivity will be the same as using chemical fertilizers

I will add this question which is on the Sustainable Agriculture Group on LinkedIn:

How to convert from agrochemical farming to a fully organic farming system without acquiring any losses, and even with increased yield on the first cropping season of its initial input?

Well-managed organic and biological fertilization aims at conserving soil quality by taking advantage of ecological interactions, although it can be successful in all soils. For its part, chemical fertilization has an environmental impact but it is successful when it is necessary to achieve good levels of productivity. then I consider that there can be a balance between the two schemes, under an integrated management of soil fertility, where the ecological management of the soil, together with the help of bioefectors, phytostimulants and soil quality conditioners aim to optimize the use of chemical fertilizers.

Yeah of course the Organic Fertilizers are better in terms of natural and pure growth of plants, but the chemical fertilizers are good for faster growth and better yield. Its recommended that Organic Fertilizers in a proper dose shall be used for sustainable agriculture.

Organic manure is more advocated than chemical fertlizers. The importance of organic manures is being realized again because of the high cost of commercial fertilizers and its long term adverse effect on soil chemical properties. Use of organic manures delivers many agronomic environmental and societal benefits and enhances long-term agricultural productivity and production.

I totally agree with Pratap Naikwade 's opinion.

Theze issues have relevance only when organic manures/ composts are produced usung on-farm residues...

I agree with you totally Dr. Pratap Naikwade that using chemicals has long term adverse effect on soil chemical properties, and on the long run the compost will be the best for quality and quantity

Thank you Dr. Anoop Kumar Srivastava , and I agree with you, and we are doing research on the compost which is modified from the farm and animal residue

Good luck with your research, Masnat Al Hiary!

Organic fertilizer is better than chemical fertilizers, but the combination of the both types keep crops production and agricultural stability.

Article Utilization of Compost and Compost Tea for Improving Egyptia...

Chemical fertilizers are highly concentrated in nutrients needed by the crop. German chemist August von Liebig in the 1840's discovered that plants respond to high concentration of nitrogen and when Haber and Bosch developed in 1909 the laboratory process to fix nitrogen that is what launched 20th century agriculture into the chemical approach paradigm to achieve food production. Therefore I would say that chemical fertilizers can be valuable to achieve high crop yields now! These gains are not free of disadvantages however. I am referring to the risks of contaminating water when using chemical fertilizers and supporting an agriculture that in a linear way will breed for cultivar that better responds to chemicals. Also, soil salinity will increase with time and location, depleting the soil of its microflora diversity, which is linked to its own biological capability of regenerating fertility in the soil. Most importantly, chemical fertilizers require non-renewable energy from fossil fuels to be manufactured and this adds another heavy inconvenient to a sustainable food production. Biofertilizers such as compost, compost tea, manure, etc. are not as highly concentrated (as a matter of fact are considered soil amendment and NOT fertilizers), however they are excellent in "feeding" the soil microflora and support its diversity. Obviously, to succeed in producing consistent food outputs with biofertilizers we need to rely more on landrace crops, rather than hybrids, or GMOs as these coevolved in the environment where traditional, peasant agriculture developed. Modern, industrial agriculture relies too much on chemical fertilizers use and this approach has affected very badly the ability of the soil to regenerate its own fertility.

Thank you Dr. Bruno Borsari for sharing this valuable information, and as you Have mentioned that industrial agriculture relies too much on chemical fertilizers use and this approach has affected very badly the ability of the soil to regenerate its own fertility.

Combined use of Organic and Inorganic is best. Because it ensure sustainability as well as environmental safety.

As off now, no research proved inorganic fertilizer use will have negative impact on grain or final economic product. It has adverse effect on soil and water but not on crop. It has only positive effect on crop except fertilizer like rock phosphate or other which has heavy metal. Other wise use of inorganic fertilizer has no negative effect on crop.

Of-course OM increase soil health, but it may not be sufficient for crop demand and availability of OM in market also should be considered before advocating it to farmer.

Organic fertilizers have very low NPK content whereas chemical fertilizers have much higher content of the same nutrients. Because low nutrient content (

I prefer organic but for production i recommend integration of both

Regarding to the answer of Bruno Borsari that Organic fertilizers have very low NPK content whereas chemical fertilizers have much higher content of the same nutrients. We can produce compost which contains high content of NPK.

Good qustion

We can conclude from the previous discussions that it is preferred in the first stage to use a combination between the chemical and organic fertilizers, them we have to reduce the chemical one accordingly.

Ask any gardener whether they prefer organic or chemical fertilizer, and chances are you’ll spark a lively debate.

Yet there are significant differences between organic and chemical fertilizers in terms of nutrient availability and the long-term effects on soil, plants, and the environment.

If you wish to live in harmony with nature and make a lasting improvement in your own patch of earth for generations to come, organic fertilizers outweigh chemical fertilizer by leaps and bounds.

Both have their own importance, however integrated application of both is more beneficial than individual use.

It is always beneficial to use such diverse sources of nutrients which have different dynamics of nutrient release pattern , in order to meet the constant nutrient supply throughout the growth period of a crop . In that context , combination of both would be far better than either of

the two alone

Is there any study on rhizosphere hybridization and nutrient dynamics..??

The fact is that food production is as difficult as the world's population without chemical fertilizers. Still, methods such as biological and organic fertilizers can help improve soil fertility to some extent, which ultimately increases agricultural production. However, using organic and biological fertilizers increases food health in agricultural products.

I think there is no comparison between these 2 nutrient sources viz. Organic and inorganic sources as both of them have utility in different aspects..Both of these sources releases ionic form of nutrients for plant uptake, it's translocation followed by assimilation.. inorganic fertilizers undoubtedly release nutrients quickly and also in larger amount. After application in the soil, it only hydrolyze by adding water to convert it in available form or ionic one..release pattern is different from both of these sources..in organic fertilizers, there will be slow release, very lesser amount of nutrients present hence more quantity has to be applied..after adding in soil, there will be microbial attacks, release of polysaccharide, mucilages so as to bind soil particles making aggregation , improve water holding capacity and influence many more physical, chemical and biological properties in a positive manner..however combination of both are viable option

Integrated usage will be fruitful and perfect, so as to feed the entire world population with diminished damage to our environment.
