Thats a premier question , how to apply fertilizers , individually or mixed. However, application of individual fertilizer would be costly in application due cost labour involved in application. On the other hand, phosphatic fertilizers are usually avoided with micronutrient containing fertilizers . Fertigation proves to be the best mode of action all mixed fertilizers , phosphoric acid augers well with any of the conventionally used fertilizers to domesticate into fertigation..

Thanks Dear Dr. Anoop Kumar,

I am agree with you fertigation as a system is so good, but in some case maybe individual application also shows impact effect on yield and quality of crops. For example, during several researching I found that potassium alone had significantly affect of fiber quality and caused to improve textile properties which more important during spinning process.

That is quite possible but when fertigation as a system of nutrient delivery is considered , we need partitioned nutrient applucation across critical growth stages inclusive of multiple nutrients depending their requirement . However, such informatiin with regard to tuning fertigation carrying specific nutrients at different physiological growth stages are extremely lacking.

Any , why to advocate individual application of nutrient through fertigation. We have been effectively operating fertigation carrying multiple nutrients in crop like citrus. Please look at the operational part plus nutrient requirement. of a given soil is deficoent of N , P and Zn . Would you prefer to apply individually or apply all three together to mitigate the existing deficiencies of those three nutrients , so that crop doesnt suffer even for a day. ...

Surely, based on plant requirements to nutrient we should to add fertilizers, but in this situation just want to display affect each menieral separately. If not, multiple fertilisation causes to cut the end cost.

Generally, fertilizers are applied in crop field through top dressing by manually before seeding and/or after seed sowing. After crop establishment, need to top dress fertilizers in different crops, especially urea at vegetative stage. Sometimes fertilizers have to spray in critical stage. Then the dose need to be adjusted to prepare solution.

Fertilization rates may vary from variety to other variety. So, if you have a fertilization rate, you can use mixed or individual fertilizers. However, before deciding to use a mixture or individual fertilizer, a cost calculation should be made on the maximum yield that can be obtained. Besides, if you use mixed one, you should use individual fertilizers to complement the incomplete part such as phosphorus or potassium. Because you may not get the ratio you want from mixed fertilizers.

Fertiliser nutrients may be applied as single nutrient fertilisers, compound fertilisers (all nutrients within a granule) or mixed fertilisers (blends). Nitrogen is frequently applied as single nutrient fertiliser whereas P and K as complex or blended fertiliser. The relative importance of each type of fertiliser type will depend on soil analysis and crop species. The more knowledge available about the nutrient content in the soil or even plant, the more single nutrient or blended fertilisers will be applied. Obviously complex fertilisers are the most expensive and are more relevant in vegetable and specialty crops. Blended fertilisers will depend on the distance to the next blending plant if the farmer himself will be able to make his own blend.

The application of nutrients in rainfed crops depends on the actual and potential fertility conditions of the soil, determined by chemical analysis, on the microbiological state of that soil, on the species to be cultivated, on the meteorological conditions expected in the short, medium and long term and the economic expectations of the farmer.

A strategy can be proposed exclusively from the economic point of view, to maximize the monetary return on each dollar invested. On the other hand, a tactic can be established to maintain or improve the quality of the soil where agriculture is done. In the first case, the only interest is to increase the yield and quality of the harvested fruit, while in the second, the harvested product and the composition of the residues that remain in the soil must be considered to nourish the microbial biomass and favor its stabilization in more stable Organic Matter..

High mobility nutrients, such as Nitrogen, must be applied as close and efficiently as possible to the moment of maximum demand of the crop (for example, in full grain filling, to favor the generation of proteins in wheat and corn). Less mobile nutrients, such as Phosphorus, must be periodically replenished so that they form a permanent part and maintain a high level in the soil exchange complex, regardless of the application opportunity.

It depends on the different factors and has different aspects. But, when we are faced with a lack of different elements in the soil. it seems that applying fertilizers in mixed forms is more useful.

In applying Fertilizers, it is important that you first carry out a soil nutrient analysis to determine what elements are present and in what quantity. This will help you decide if you need to do the individual application or mixed.

In situations where there's low amount of the required nutrients for plant growth in the soil, you'll need to carry out a mixed Fertilizer application to increase the amount of soil nutrient whereas as if it's only an element that is deficient, you'll carry out an individual application to augment for the deficiency.

It is critical to do a soil nutrient analysis before applying fertilisers to determine which elements are present in soil and in what amounts. This will assist you in determining whether you need to do an individual application or a blended application.

In circumstances when the soil lacks the multiple nutrients for plant growth, you'll need to apply a mixed fertiliser to boost the amount of nutrients available. If is there is a deficiency of single nutrient then there is a no need to apply mixed fertilizers apply only single nutrient it will reduce the cost of production.

I have learnt a lot from this conversation.

Before thinking about application of simple Or Complex fertilizers, as known, soil testing for macro and micro nutrients should be done. Based on the report we can decide which fertilizer need to apply.. Which is cost effective.. Which method of application is better etc.

If the soil is having sufficient macro nutrients for selected crop growth and deficient in micro nutrients... No need of macro nutrients application....Basal application of FYM or vermicompost etc.. enough and you can go with micro nutrients foliar spray at recommended stage. If soil is deficient in both nutrients then basal application of phosphotic fertilizers and half dose of recommended nitrogen should be applied then after plant growth remaining dose of nitrogen and potassium fertilizers are top dressed. If one nutrient deficiency is reported.. We can go for only that individual nutrient application.if u can effort the fertigation unit and water soluble fertilizers cost.. Any form of fertilizer Application through fertigation is the better way. Through fertigation we can reduce the cost of labour for manual application and it is having more water and nutrient use efficiency. If the person can't effort they can go with manual application as discussed before. However, application of individual fertilizer would be costly due to labour requirement. So, if we apply nutrients according to soil testing

report we can reduce the cost of fertilizers and labour wages.. And we can decide which form of application of fertilizers is best.. Thank you😊

Fertilizer (s) can be applied to the crop field according to the needs of the crop? When an individual fertilizer is applied to a crop the labour cost will high be higher. Alternatively, labour cost will be reduced if different fertilizers are applied after mixing them altogether.
