7.12 Definition of the terms "triangular spreading pattern“ and "trapezoid
spreading pattern"
What is a triangular spreading pattern?

Total spreading width
The features of what is referred to as a triangular spreading pattern are the wide
spreading edges and the resulting large overlap zones. The fertiliser is spread
significantly wider than the actual working width, well into the next track depend-
ing on the working width and type of fertiliser.
As a result of these features this spreading pattern is less prone to influences
such as
Side wind
Humidity
Changes in fertiliser type and quality.
The triangular spreading patterns are generally achieved with fertilisers that have
very good flight properties and very even grain sizes (such as ammonium nitrate
lime), even with larger working widths (up to 28m).
