Equipment: Testing and services

The operating supplies and consumables segment includes numerous products from a wide range of applications - from fertilising lime and disinfectants to food additives.

The development and application of modern, knowledge-based and practice-oriented testing and measuring methods characterises the work of the test engineers. The DLG Seal of Quality and DLG Quality Mark stand for neutrally tested and independently confirmed product quality.

The tests of farm inputs comprise product and in some cases also process certifications. All DLG-awarded operating resources are subject to continuous monitoring. The consistent product quality is ensured with repeat tests or audits of the manufacturer performed at least once a year. This distinguishes the DLG awards from many other quality marks and is of particular importance to the end customer.

In addition to tests according to DLG standards as well as approval-relevant tests according to standards and regulations, the DLG Test Center offers comprehensive services for quality assurance as well as on the basis of customer-specific test requirements for research and development purposes.
