The Calibrator Icon is available on all L line and M line spreaders. It provides quick and easy machine set up, application rate independent of forward speed and on the move rate adjustment. The system also records information relating to a particular field including the area spread, the application rate and the total quantity of material applied, this information is all easily downloadable to assist with record keeping.

With 2 way RS232 communication the Icon can accept software updates and is compatible with all leading GPS systems such as Green star, SOYL, etc

With fertiliser prices riding high, farmers need the maximum accuracy and effectiveness of each kilo that they apply. Agricultural businesses are also increasingly bound by the need to produce precise records of the amount of nutrients they apply, whether to comply with NVZ regulations or meet the requirements of assurance schemes.

The business of fertiliser spreading is becoming more reliant on modern technology; yet this technology depends on a development which Danish manufacturer Bogballe pioneered almost 20 years ago - the weigh cell.

Through our exclusive Zurfcom software two way communication is established between the spreader and the farm office. Information on fields to be spread such as application rates and machine settings can be established in the office then transferred to the spreader. Once the spreading has been done a record can then be transferred back to the farm office for precise record keeping. All data is simply transferred via SUB

New for 2011

All KRM weigh cell spreaders can now be supplied ISOBUS ready. Easy and logical operation have always been key guidelines in the development of our electronic controllers. To continue this strategy the ISOBUS solution displays the same easily understandable graphical layout on the tractors terminal.

Windermer Contractors of Tavistock, Devon have found that the automatic calibration of his M2W spreader offers considerable time savings.
"We may be changing products once or twice a day, and it is so much quicker," says John Windermer. "You also know exactly when the spreader is getting low on fertiliser, so refilling is more efficient."

Another bonus is the spreader's ability to automatically adjust application rates as flow rates alter in changing weather conditions - an occupational hazard in the damp south west.
"Application rates are always correct, regardless of the conditions, because the weigh cells monitor and adjust the machine settings," John adds.

Dean Farm, Bishops Waltham, Hants, purchased an M2W this season in order to switch to variable rate spreading, and farm foreman Jamie Wymbs says: "We will use the Zurf controller on the M2W in to spread variable rate P&K according to application maps on 750 acres of arable land and some grass. I have already applied some N with the spreader and it looks extremely accurate - on 180 acres of rape I applied eight bags and it was just 10kg out. I could not have achieved that level of precision with our previous spreader. "

Jamie also plans to use spreading information from the Zurf controller for recording purposes, using a memory stick to download it and software from Zurf.com to process the data. "It will be useful for inspections or our own records, and what's more, because of the weigh cells, we know it is spot on," he says.

He points out that the technology should make savings on the farm's grassland, due to the increased accuracy of spreading.

Andrew Fuzzell of Church Farm, Rode, near Trowbridge finds the precise nature of spreading with a weigh cell sprayer a real advantage, as he explains: "I know the correct rate is going on, regardless of conditions. We use a lot of chicken manure in addition to the mineral fertiliser and I can be confident that nutrients are not being over applied to the detriment of the crop. In addition, I'm not wasting money on fertiliser I don't need."

And as Andrew points out: "With fertiliser at £400 per tonne, if I can save ten tonnes that makes a considerable difference."

Contractor Philip Matthews has long been a convert to the technology, explaining: "We use bulk fertiliser, and the weigh cells allow the quantities being used to be measured accurately. There's no need to recalibrate when moving between fields as you can see exactly what is in the hopper."

Philip also finds the ability to program applications for each field into the controller a real time saver. "We don't have to take the paperwork with us each time, and you can see at a glance how much was put on last time, which is particularly important where clients are applying muck as well or are in an NVZ."
