Seed encrusting and pelleting
Large scale planting systems are
increasingly being used to boost
production. These mechanical devices
work better when the shape of the seed
is more uniform: the seeds "flow better"
in a mechanical sense. Pelleting caters
to this type of requirement, by creating
round pellets of a standardized size.
These pellets (round spheres) and
encrustings (lesser degree of build-up)
have additional advantages:
-
Better plantability (as described
above)
-
Use of phytotoxic products
-
Higher percentage of marketable
fraction
-
Weight and volume increase
-
Uniform distribution and high
recovery of the applied pesticides
-
Addition of biological control
agents (bacteria)
-
Addition of growth promoting agents
-
Addition of identification systems
(from color codes to micro taggants)

There is a wide variation in pellet
types: |
|
-
MELTING PELLETS
The pellet stays around the seed,
but dissolves evenly away.
-
SPLIT PELLETS
The pellet splits open upon water
contact and gives a free way to the
germ.
-
PROTECTOR PELLETS
Provides additional brrier between
coating and seed, without inhibition
of water or oxygen exchange.
-
IDEAL CONDITIONS
Professional pellets or greenhouse
pellets.
-
FIELD CONDITIONS
For a wide range of climatic
conditions and soil types;
pellets for field
conditions.
