You’re standing at
the top of a ladder. In your left hand you have a feather. In your
right hand you have an exact replica of that feather except it is
coated with lead.
OK…now the fun
begins. You drop each feather from the top of the ladder with the
goal of hitting the center of the “X” that you just drew on the
Which feather has
the better chance of hitting the mark?
The lead coated
feather of course. Why? You ask. Well…the lead coated feather will
obviously have a truer, straighter drop that is less affected by
outside influences on the way down.
Let’s say you now
put the ladder on wheels and while the ladder is moving, you try to
hit a several different “X”’s spaced 1 foot apart down a row. You
not only will be more accurate with the heavier feather, you’ll be
able to travel faster on the ladder and still have some accuracy
compared to the feather without the lead coating.
What does this
have to do with Seed Encrustment? Read on and I’ll try to explain.
What is Seed Encrustment?
is similar to coating that feather with lead. You usually
don’t change the shape of the seed much, but you add quite a bit of
weight to the seed. This may be the best way to maximize your
planters ability to precisely place each seed in the row i.e. hit
the “X”. And like the ladder on wheels you can usually plant
encrusted seed at a faster tractor speed than a light density seed
On the picture is
an example of sh2 sweet corn before and after encrustment. In the
case of sh2 sweet corn, you not only add weight to the seed, but you
fill in the relatively large depressions in the seed, making a
smoother seed surface which is more easily handled by most
planters. The ending result is usually more evenly spaced plants,
with less skips and doubles. In the case of sweet corn, this can
lead to more marketable ears/acre and more profit for you.
talk about film coating seed and some of the new technologies being
introduced in the article “Film Coating Seed – Very Pretty”.
we’ve talked about seed pelleting, encrustment, and next film
coating, we’ll also try to summarize the differences between these
processes and why each has a place in precision planting.
