This was taken directly from an email sent to us by one of our most successful organic producers- he owns 6 Einbock Tined Weeders ( he used to run Kovar) He has counseled with many producers on the use of a tined weeder, why they should buy Einbock and how the Einbock can increase yields and profits.

 

This is how I did the math with him:

He said he did some sort of no-till, minimum till, or zone-till of soybeans
into corn stubble.  So the weeder would probably not work there (it would
rake up the corn stalks.)  But he said he had 60 acres of corn, and he
wasn’t thinking that would be enough to justify the investment (I think he
said $7,000).  I asked if he thought that that the one year of 60 acres
should pay for the entire weeder.  He said no, that he would figure it over
5 years.  I said let’s use 4 years.  $7,000/4 years= $1,750.00.  I said
let’s round this up to $2,000, because he’ll need to order it, receive it,
and put it together.  I divided the $2,000 by 60 acres and came up with $33
per acre.  I asked him what he gets for a bushel of corn.  I think he said
$8.00.  I said let’s leave some margin in case the price declines a bit and
use $7.50.  Then divided $33 per acre by $7.50 per bushel and came up with
4.4 bushels per acre of corn.  I then asked what he got for yields and I
think he said something like 100-125 bushels per acre.  I then discussed
with him how, clearly, the improved yield that he could expect to achieve by
using this superior weed management tool would be expected to exceed 4.4
bushels per acre.  I would expect that it would be some multiple of this -
if I had to estimate it would be perhaps 5 times this, or 22 bushels per
acre.  We then discussed how it would really depend on the year if it would
be as low as 4.4 bushels, but could quite possibly be 44 bushels; it just
depends on the season.  But that clearly the investment was a no-brainer,
because not only does it pay for itself fast, but it is engineered and built
to exacting standards and so, on top of this, would last him many, many
years.
