SCS Fertiliser and Slug Pellet Trials

SCS’s reputation within the agriculture and amenities industries is built on 30+ years of working with machinery and agrochemical manufacturers and importers. SCS have aided in research and development to give manufacturers a thorough understanding of how their products interact with different machines. SCS has seven of the most popular fertiliser spreaders on site for trials work from manufacturers including Amazone, KRM/ Bogballe, Kverneland, Kuhn and Teagle, which cover the two types of spreading mechanism in the UK.

The Amazone, Kuhn, Kverneland, Sulky and Vicon machines have discs that spin away from each other so the right spreads right and the left spreads left. The other type of system is used by KRM/ Bogballe and Teagle, where the discs spin towards each other. Both discs spread across the whole of the spread width, so the right not only spreads to the right but also to the left. Each spreading system affects the material differently to give either a triangular or trapezium spread pattern. It is recommended to test at least one machine of each type to check the fertiliser will spread no matter the spreading system. SCS can tailor trials to suit your requirements; whether you’d like to know how far your material will spread, whether it segregates or simply what settings to use through a variety of machines at different widths, see what SCS can do for you.

Fertiliser Spreader Trials

The following spreading trails are to produce settings for operators to use when applying products on farm. Carrying out this trials work will alert manufacturers to any discrepancies in settings compared to those derived from a test hall. In many cases in-field testing produces different settings to achieve an optimum spread pattern due to the consideration of external factors.

1.

Fertiliser Analysis

A check of the fertiliser's characteristics including bulk density, crush strength and size. These will determine how the product spreads and can alert the manufacturer to issues such as variation between batches.

2.

Tray Test

The spread pattern is assessed by driving through a set of trays with the spreader running, the material is collected and the Coefficient of Variation (CV) calculated. This gives a figure of accuracy for that pattern. Adjustment of the spreader set up will then be made to ensure the best pattern possible is achieved.

3.

Report

Discussion of findings to include; how material spread and widest width achievable with each machine.
Settings for different widths and rates depending on manufacturer requirements.

4.

Segregation Trials

Discussion of findings, how material spread, and widest width achievable with each machine before segregation becomes visible.
Material is bagged & labelled at regular intervals either side of the spread pattern to show distribution of blended products across spread width.
These samples can be sent to a lab for chemical analysis.
