Target values for Phosphorus Content-Classes in Soils considerably lowered

At their meeting on the 6th of March 2018 in Osnabrück, VDLUFA sections I and II adopt the amended VDLUFA Standpoint “Fertilization of Phosphorus according to Soil Analysis and Plant Need”. First published in 1997, the VDLUFA Standpoint was evaluated during diverse section and project group meetings. Scientific data from fertilisation trials as well as numerous publications have been considered during the re-evaluation. Based on these findings, target values for content classes A to E in arable and grassland soils were considerably lowered. Furthermore, an adaption to dry sites could be considered.

The standpoint is only available in German and can be downloaded free of charge.

Together with VDLUFA NIRS GmbH, Working Group NIRS of Section VI offers workshops on NIRS

The workshops address all personnel working in the field of near-infrared-spectroscopy (NIRS). The workshops’ goal is to improve their working procedures with NIRS.

Two kinds of workshop are offered:

When desired, workshops can also be offered for the following software-packages: UCal, Unscrambler, Opus, Grams, Alligator.

Further Information about the workshops can be downloaded (see above; in German only). For subscription or for further questions please directly contact the responsible persons at VDLUFA NIRS GmbH.

VDLUFA publishes standpoint on Requirements on Soil Examination Methods for Determination of Fertiliser Need

VDLUFA Sections I and II publish the standpoint Requirements on Soil Examination Methods for Determination of Fertiliser Need. The standpoint names the minimum requirements that have to be met by soil examination methodes to use the analytical results for a well-grounded determination of fertiliser demand. Those requirements shall enable farmers to evaluate the precision and informative value of the analytical methods as well as the reliability of fertilisation recommendations based on these analytical results.

The standpoint has only been published in German and can be downloaded free of charge on the VDLUFA homepage.

VDLUFA honours merited scientists

At the 129th VDLUFA conference in Freising, the president of VDLUFA, Prof. Dr. Franz Wiesler had the privilege to hand over the

  • Sprengel-Liebig-Medal in Gold to Doris Krieg from the Betriebsgesellschaft für Umwelt und Landwirtschaft in Nossen in honour of her longtime commitment to the VDLUFA section VI ‚feed analysis‘ and her outstanding merits concerning the organisation of VDLUFA interlaboratory comparisons for feed analysis
  • Sprengel-Liebig-Medal in Silver to Dr. Martina Peterhänsel from the Landesanstalt für Landwirtschaft und Gartenbau Sachsen-Anhalt in Hallein honour of her longtime commitment to the VDLUFA section VI ‚feed analysis‘ and her high merits in maintaining the connection between feed analysis and the official feed monitoring system,
  • Sprengel-Liebig-Medal in Silver to Günter Müller from the Thüringer Landesanstalt für Landwirtschaft in Jena in honour of his longtime commitment to the VDLUFA section IV ‚seed‘ and his merits for method development and quality assurance in the field of seed analysis.
Furthermore, Dr. Armin Trenkle from the Landwirtschaftliches Technologiezentrum Augustenberg in Karlsruhe was awarded the honorary membership in the VDLUFA in honour of his outstanding voluntary commitment in diverse boards of the VDLUFA.

New method about determination of fluorine in feed released


VDLUFA releases the single method “Determination of fluorine in plants and feed using ionselective electrodes” in VDLUFA-methods book VII “Environmental analysis”.

The new method provides a procedure for determination of fluorine in plants and feed. For this, the dried and ground materials is combusted and then digested using sodium hydroxide. After cooling down, the chemical extraction is suspended with hydrochloric acid under the addition of TISAB-solution. Subsequently, the solution is adjusted to a pH-value of 5.5. The fluorine content is finally determined using an ionselective electrode and calculated via standard-addition.

The method (in German only) can be ordered as a single method at VDLUFA office for 17,00 € (+ postal charges) in its printed or electronic version.

VDLUFA wants to thank Dr. Holger Hrenn (Universität Hohenheim), Dr. Joachim Bilz and Dr. Joachim Kirmas (Landesanstalt für Landwirtschaft und Gartenbau Sachsen-Anhalt) as well as Dr. Matthias Leiterer (Thüringer Landesanstalt für Landwirtschaft) for their commitment in elaborating this method.

More than 125 years of VDLUFA history - now online

The VDLUFA (Association of German Agricultural Analytic and Research Institutes e. V.) exists since 1888. Since then, the association has released four anniversary publications:

  • 1938 (50th anniversary of the association)
  • 1963 (75th anniversary of the association)
  • 1988 (100th anniversary of the association)
  • 2013 (125th anniversary of the association)

These publications provide an insight into the change, but also the stability of the association, its main focus and its external presentation.

All publications were digitised by the association’s office. And we are pleased, that all volumes can now be downloaded free of charge (only available in german).

Annual conference of German soil experts 2017 in Schleswig-Holstein

With the topic „Soil, Soil use and Soil protection in Schleswig-Holstein“, this years conference took place from 20-22th Juny 2017 in Rendsburg (Schleswig-Holstein, Germany). The purpose of this meeting was to offer a deeper insight into soil and agricultural characteristics of Schleswig-Holstein.

Jahrestag Bodenspez


This annual conference, supported by Bundesministerium für Ernährung und Landwirtschaft (BMEL), is held since 1950 with topics referring to problems of the specific Bundesland. Presentations are held on the first day, a field trip is sheduled on the second and the third day is filled with discussions about the main topics.


Presentations were hold about soil, soil use and soil protection in Schleswig-Holstein:
1. Geology and soil in Schleswig-Holstein (Mr. Burbaum, LLUR)
2. Land use in Schleswig-Holstein (Mr. Dr. Schleuß, MELUR)
3. Project “intensive-longterm-soil-observation” (Mr. Dr. Filipinski, LLUR)
4. Guideline „Soil protection on construction sites“ and current projects in Schleswig-Holstein (Ms. Dr. Bädjer, LLUR)
5. Hauling of power-pipelines through soil-wiring (Mr. Dr. Gebhardt, GZP GbR)
6. Soil compaction in Schleswig-Holstein (Mr. Dr. Elsner, LLUR)


On the field trip the specific site and agricultural developement of Schleswig-Holstein, with a special regard to soil protection, were covered. A cabbage cultivating farm (Hillgroven, Norderdithmarschen), two soil profiles at a grassland farm with cattle (St. Annen, Norderdithmarschen) and an intensive-soil- observation-site (Sönke-Nissen-Koog) were visited.

Traditionally, on the last day of the congress the internal meeting of the soil experts from all federal states takes place, where current topics of soil protection in Germany are discussed.

On 15th and 16th of May 2017, LUFA-directors from Germany and Austria met at Thüringer Landesanstalt für Landwirtschaft in Jena. Main topic of the meeting was the VDLUFA plan of action 2017 to 2019, which has been adopted in autumn 2016. Especially perspectives of the national and international interlaboratory comparisons „VDLUFA Feed Enquete“ and „VDLUFA EU Fertiliser-Ringtest“ were discussed as well as section-intern interlaboratory comparisons.

VDLUFA-trainings for technical staff shall be further extended and organised by various LUFA, in the future.

The yearly work sheets of all VDLUFA sections were confirmed. LUFA-directors will further support an active professional contribution of their staff in VDLUFA sections, working and project groups by guaranteeing the necessary financial and personal clearance. Thus, VDLUFA should be strengthen in being the nationwide most important network for scientific exchange in the topics of plant pro-duction, animal production and analytics.

Besides the professional exchange, participants spent time on „500 years of reformation“. The ex-cursion about the time of the reformer Martin Luthers, guided by Prof. Gerhard Jahreis (Friedrich-Schiller-Universität Jena), was educating and entertaining, not only for non-locals.
