accurately and evenly.
But what can a farmer do if a bulk product is being spread by a contractor? The
fertiliser physical quality should be queried. If a contractor is using 18m or 24m
bout widths, good fertiliser physical quality is essential. The standards required are
outlined later in this article. The farmer also needs to check the fertiliser spreader
and its setting. In the absence of detailed knowledge about spreaders, a farmer can
still make a number of checks:
The general condition of the spreader being used;
Key elements, like spreading discs and vanes, should be free from wear;
Signs of maintenance should be determined;
The specification of the machine;
Is it equipped with the correct spreading components to achieve the correct
spread pattern at the chosen bout widths with the fertiliser to be used? Ask the
contractor to verify this;
Does it have proper headland/border deflector kits to avoid losses to
hedgerows?
Is there a good quality GPS system to ensure accurate bout widths are
achieved;
Is the spreader correctly set up for the fertiliser and bout width? Ask the
contractor to show you the settings required for the particular fertiliser and
bout width;
Is there any evidence of the spreader having been checked? Many of the larger
merchants may now be stipulating that there are pre-season checks on the
spread quality of contractor's spreaders; and
Reputation is there a history of satisfied customers of the contractor/
merchant? Tillage customers would probably be a better guide as they would
be more sensitive to poorer spreading.
THE CHALLENGE TODAY IS GREAT
Todays' spreaders have a huge challenge with farmers/contractors using bout
widths from 6m to 36m. Broadcast spreaders rely on forming an overlapped pattern
(see Figure 1) to give an even spread. This is challenging in perfect conditions, but in
the field with bumpy ground and wind, it's much more difficult.
MACHINE DESIGN
Machine design has a huge impact on how evenly the fertiliser is spread. The only
way to assess a particular model is to have a spread test report where evenness of
application is measured. While the major fertiliser spreader manufacturers have
their own test facilities capable of giving very accurate test results, they usually only
put the best results in their brochure. Results from independent test halls are of far
more value, but these tests are increasingly rare. You should look for an independent
test result and always favour a manufacturer who provides one.
WHAT TO LOOK FOR IN A TEST RESULT
The evenness of spread is frequently summarised by a single figure called the
coefficient of variation (CV) the lower the CV percentage, the better the spread
pattern. A CV value of less than 15 per cent would be acceptable in the field,
but figures of 5-10 per cent should be demanded from a test hall where perfect
conditions prevail. But the CV does not tell the full story. The shape of the basic
spread pattern is important. A triangular shape like that in Figure 1 tells us that
the spread will be a little less sensitive to wind or fertiliser variation than the more
shouldered pattern of Figure 2. The spreader producing a pattern like Figure 2 would
need to be very carefully set to suit the fertiliser characteristics and spreading
conditions.

For anyone making round bales, the familiar
black and white striped netwrap is easily
recognised as TamaNet, a product of Tama
Plastic Industry. Almost two out of every
three rolls of netwrap sold each year are of
Tama origin. The introduction, in 1999, of their
familiar and game-changing black and white
TamaNet Edge to Edge netwrap changed the
way netwrap performed in a baler, finally
allowing the net to fully cover the bale,
instead of shrinking in width. Achieving this
consistency of performance, in every baler
make and model was not an easy process to
achieve or to understand.
Many other, clever and unique creations have
followed making the baling experience easier
and adding to the `bottom line'. Tama Plastic
Industry is kibbutz-owned, meaning all the
members of the kibbutz are co-owners of
the business. Such a unique situation brings
a very strong passion for success. It is the
kibbutz's very successful and large-scale
farming business, co-located alongside Tama's
headqaurters that brings a uniqueness to this
very important business.
Close to the main Tama site, is the kibbutz
farm, with a wide range of round balers, both
fixed and variable chamber, from at least five
different original equipment manufacturers
(OEMs). This presents the unique ability to
try new products, or specific innovations,
in prototype form immediately, on their
own balers, working in their own fields
immediately across the road from the factory.
Product development can advance much
quicker and with greater ability, from the fact
that many of the highly skilled R&D teams
and factory workers on the headquarters site,
have long and intimate knowledge of farming
life and baling in particular.
The ability to produce longer and more
cost-effective netwrap was achieved from
a change in product and raw material
technology, something Tama has worked hard
on, and continues to lead on. This change in
technology has allowed many more metres
of netwrap on the roll, while keeping within
the same basic roll weight that customers
have become used to. This is achieved without
increased roll diameter, so as to remain within
the maximum roll size to fit in every baler.
TamaNet+ 4,500m is the longest netwrap the
market, significantly increasing baler output
resulting from fewer roll changes over the
season. TamaNet is, specifically recommended,
and approved by all leading OEMs' balers.
