EVO NIR 4.0: Expanded spectrum of applications
By Dr. Ulrich Rubenschuh, DLG Test Centre for Technology and Farm inputs
Already during the first measurements, the NIR sensor from Dinamica Generale was able to achieve recognition for the total nitrogen content in pig slurry. With version 4.0, new software versions and calibration models are now being used - with a significantly wider range of functions.
Powerful control for slurry technology
By Dr Frank Volz, DLG, and Dr Ulrich Rubenschuh, DLG Test Centre for Technology and Farm Inputs
At the beginning of 2022, the Bauer Group joined the CCI (Compence Center Isobus) with the brands BSA and Eckart.

The DLG Test Centre compared the recommendations of the Claas CEMOS assistance system and manual adjustment in terms of specific fuel consumption and area output.
Amazone seeding technology: Precision in the field
By G. H. Schuchmann, DLG Test Centre Technology and Farm Inputs
Field emergence, longitudinal plant distribution and lateral fertiliser distribution - in DLG tests of precision air seeding equipment, the quality of work is closely scrutinised. In the DLG test, the 6-row maize seeder Precea 4500-2CC Super from Amazone, equipped with PreTeC sowing units, was examined.
Bale density measurement: Non-destructive screening
By Dr Frank Volz, DLG Test Center Technology and Farm Inputs
Determining the density distribution in round and square bales with high resolution is one thing, but only the mobile density test stand of the DLG Test Centre can carry out these measurements non-destructively and thus also repeatably. We present the testing possibilities.
Stenon FarmLab: Spade analysis of soil samples
By Dr Frank Volz, DLG Test Center Technology and Farm Inputs
In order to be able to control fertilisation and plant nutrition, there is no getting around soil analysis. The Stenon FarmLab promises the necessary values almost in real time - instead of taking time-consuming samples, a kind of spade is simply stuck into the soil.
Slurry spreading: Optimal cross-distribution
By Georg Horst Schuchmann, DLG Test Center Technology and Farm Inputs
The challenge is clear: in low-emission, ground-level slurry application, the slurry must be distributed evenly to all outlets. And this is independent of the working width, which on the market ranges from less than 6 m for small booms to up to 36 m for large booms. With the latter, several distribution systems are then needed in parallel to supply the up to 120 hoses.
DLG Practise Monitor: Front loader remains No. 1
By Dr Frank Volz, DLG Test Center Technology and Farm Inputs
What technology do leading farmers rely on when it comes to loading and unloading, lifting and clearing away? The current DLG-PraticeMonitor shows: In agriculture you can't avoid the front loader, but other loading technology is noticeably on the rise.
John Deere 9800 forage harvester: Powerful and economical
By G. H. Schuchmann, DLG Test Centre Technology and Farm Inputs
While the maize sowing is in the starting blocks, it is time to think about the subsequent harvest. With the 9000 series, John Deere has expanded its forage harvester generation with a second series. The 870 hp version was tested by DLG in maize on high-yield sites in northern Italy.
ExxonMobil lubricant combination: Combining well to save fuel
By Sander Schwick, DLG Test Centre for Technology and Farm Inputs
Some consider them to be a hoax, others praise the effects to the skies. Do special oils only benefit the manufacturer or also the farmer? The DLG Test Centre compared a lubricant combination from ExxonMobil with standard mineral oils.

CLAAS NIR sensor for forage harvesters
By Georg Horst Schuchmann, DLG Test Center Technology and Farm Inputs
Whether with combine, slurry tanker or forage harvester: applying near-infrared spectrometry on materials being handled enables continual assessment in real time for nearly all constituents – depending only on the calibration curve applied. Claas has presented for testing by the DLG a sensor for measuring moisture content in grass harvested for ensiling.
Tractor model descriptions: No standardised information
By Niels Conradi, DLG Test Center Technology and Farm Inputs
Against the widely held assumption, precise performance of tractors cannot be worked out directly from the model designation. Here, we explain the differences to help you avoid buying a tractor with the wrong power output for the job you have in mind.
Kuhn Universal seed drill Espro 6000 R: Precisely drilled
By Georg Horst Schuchmann, DLG Test Center Technology and Farm Inputs
With seed drills, differences between target values and those actually achieved in operation should be as small as possible. This applies, for example, to seed metering accuracy, lateral distribution i.e. quantity differences between the individual coulters, or placement depth. With the Kuhn Espro seed drill, every aspect was carefully checked at the DLG Test Center.
Self-propelled vertical feed mixer wagon Siloking Selfline: Drives itself (almost)
Dr Harald Reubold, DLG Test Center Technology and Farm Inputs
Cattle feeding cannot be imagined nowadays without feed mixer wagons. And the question arising with every investment, especially in an expanding enterprise, is: »Tractor driven or self-propelled?« A self-propelled machine from Siloking has been subjected to a comprehensive working performance test at the DLG Test Center.
