SACCS trials:

SACCS carries out both contract and in-house trials each year. Where additional crops or targets are stipulated, then trials are located off-site; SACCS has a considerable network of contacts for appropriate placement of trials.
Nick Burton is the Agronomist in charge of the trials at Stetchworth. Nick’s trials’ experience started in 1979 with ICI at Jealotts Hill and continued whilst working for Willmotts / UAP in East Anglia.

Nick Burton

In addition to conducting the trials at Stetchworth he also acts as agronomist for clients in Suffolk and Essex.
Since autumn 2009 the trials have been located in field 57E, within which all the replicated trials are undertaken; the 6.0 hectare field is split into 6, 0.8ha strips which are rotated each year so as to provide 'fresh' ground on which to conduct each year's trials.

The trial plots are are drilled using an Oyord small plot drill and sprayed using our one-man boom plot sprayer (offset for applications beyond GS32), whilst overall applications are made using a Hardi tractor-mounted sprayer. Variable rate nitrogen trials receive fertiliser via a modification to the Oyord drill while overall fertilising is achieved using a full-width Horstine Farmery Cascade machine.

Off-site trials are established using a self-propelled Wintersteiger drill.

The basic plots are 16 metres in length (shortened to 14m at harvest) and 2 metres wide, replicated 3 or 4 times in a fully randomised layout. The trials are harvested using a 2m Deutz Fahr 660M combine with 'air-assist' to ensure complete cleaning of the grain pan between plots.
