Due to the low fertilizer use efficiency of conventional methods of application of some advanced methods of fertilization like fertigation are developed which have very high fertilizer use efficiency and save the fertilizers up to 25 percent and improve the quality of produce. In modern methods of fertilizer application, main emphasis is given on the efficient and economical application of fertilizers with quality produce without endangering the environment which is the need of hour.

Fertigation Method
1.

Bulk of fertilizers are applied at one time

with one two additional splits.

Fertilisers can be applied in small quantities one or any number of time amounting to many split doses.
2.

Scope for break down is greater as N

spreads over more area.

Scope for break down is less since only a limited area of soil with greater microbial activity is in contact with Nitrogen source
3.
Uptake ranges from 10-30%
Uptake is much higher even up to 80-90%
4.
Uptake is influenced by drought
Question of drought does not arise.
5.
Alternate wetting and drying of soils occurs leading to greater breakdown of nutrients.
Does not arise.
6.
Anaerobic situation during flood irrigation result in poor uptake of nutrients.
Does not arise.
7.

More chances of soil and atmospheric

pollution.

No chance for pollution.
8.
Low yield with poor quality
Higher yield with best quality.
