- In case of transplanted crops, the seedlings could be planted directly into the
hole. In case the transplanted plants are not erect and steady, care should be taken
to see that the saplings do not fall on the mulch film. This would lead to burning
and mortality of the tender plants.
- In such cases, it is advisable to mulch after the establishment of the plants (after
3 to 7 days of transplantation when the plants are steady and erect).
- For mulching established seedlings, one end of the film along the width is buried
in the soil and the mulch film is then unrolled over the saplings. During the process
of unrolling, the saplings are held in the hand and inserted into the holes from
the bottom side, so that it could spread on the top side.
- In case the mulch film needs to be used for more than one season, the plant is cut
at its base near the film and the film is removed and used.
The best way of irrigating mulched crops is through drip irrigation. Under drip
irrigation, the laterals are kept under mulch film. Irrigation and fertigation could
be carried out without any problem. In flood irrigation, the channels are made along
the un-mulched area and irrigation is carried out. Irrigation through sprinklers
is also possible.
Application of Fertilizer
In case of drip or sprinkler irrigation, fertilizer application is done in liquid
form through drip or sprinkler irrigation system. However, under flood irrigation,
all fertilizers & soil-applied chemicals are usually placed in or on bed before
mulch is applied.
Removal & Disposal of used Mulch Films
Non-degradable mulch films do not disintegrate in the soil. Therefore, after use,
mulch film should be removed & disposed off properly so as to avoid any plastic
