Day 1

Date: 23.11.2013
Topic: Best practies in making compost and treating manure – results from scientific work
Location: Forschungsring e.V., Darmstadt and Dottenfelderhof, Bad Vilbel
Duration: 9:00 – 21:00
Present: Uli Johannes König, Meike Oltmanns, Erik Frydenlund, Birthe Holt, Sandra Percać, Jasminka Iličić, Ivan Kosak, Drago Purgaj, Sonja Purgaj, Danijela Kocuvan, Radovan Šuman, Vesna Čuček.
Afternoon (Dottenfelderhof/Bad Vilbel): Ansgar Voortmann, Matthias König

Visit of “Forschungsring für Biologisch-Dynamische Wirtschaftsweise e.V.” in Darmstadt one of the world oldest institutes for ecofarming. Dr. König introduced the beginning of work in the early fiftieth as a place for scientific research as well as for fundamental work in ecofarming especially biodynamic. Contacts to nearly all of the german Universities with an agricultural faculty exists.
World wide activities have been carried out over decades to improve the world wide DEMETER-movement.
In the morning Dr. König held a presentation with the theme Best practies in making compost and treating manure – results from scientific work”. Working with compost or manure means that you have to know first, what for the compost/manure will be: fertilizing, cultivation or planting soil or compost extracts for plant protection. Answering this question the treating of manure/compost will change. Which techniques are available on farm, only small scale handycraft or machinery equipement? Which losses from the material have to be expected and how can they be reduced? Which different qualities of compost can be reached depending on the materials beeing used for making compost? Which effects of the biodynamic preparations could be shown in practies and science?
Different qualities of manure and compost and routh materials were demonstrated on nearly 100 samples.

In the afternoon a visit of the manure storage and compost making of a public demonstration farm (Dottenfelderhof) took place. The farm shows a wide scale of activities in organic farming reaching from milk, grain and vegetable production on 180 hectar farmland to education, breeding and research work. The management of manure of different animals (cows, pigs, sheeps, horses, poultry) is a great challenge on such a large scale farm. Farmer Ansgar Voortmann mentioned that making stable manure is the solution for cattle manure, composting for all other manures and green material or organic waste from the farm. 3000 cbm compost per year are produced consisting of 1000 cbm shrubb cuts, less than 1000 cbm rest manure, the rest volume are waste products from the farm. The farm uses a compost turning machine. The turning proceeder is carried out 7 to 10 times per compost. The conversion of material to finish compost takes about 3 months. Application of biodynamic preparations was discussed.
Farmer Matthias König showed the storrage of the biodynamic preparation on the farm and discussed the special proceeder of making and applying them.

In the evening was a discussion looking to the result of the day, specially the questions comming out of the farm visit:
  • How is it possible to make 3000 cbm of compost with all the components?
  • How to handle 1800 cbm of manure from the stable?
  • The more than 150 working people on the farm are a challenge!
  • The big amounts of preparations (e.g.800 horns) for such a farm.
  • The intensive use of preparations in the stable.
  • Why is the humus content after decades of organic agriculture only on a 1,7% level? Is it the result of 100 year suggar beet production before convertion?
  • It should be possible to lift it up to 4 %.

Day 2

Date: 24. 11. 2013
Topic: Is there a need for animal manure to approve soil quality?
Location: Forschungsring e.V., Darmstadt and Hofgut Oberfeld, Darmstadt
Duration: 9:00-16:00
Present: Uli Johannes König, Meike Oltmanns, Erik Frydenlund, Birthe Holt, Sandra Percać, Jasminka Iličić, Ivan Kosak, Drago Purgaj, Sonja Purgaj, Danijela Kocuvan, Radovan Šuman, Vesna Čuček.
Afternoon (Hofgut Oberfeld): Thomas Göbel

Mrs. Meike Oltmanns held a lecture with the theme “Is there a need for animal manure to approve soil quality?” The development even in ecological agriculture is leeding more and more to a speciallization of farms. Cash crop agriculture with out cattles is the result, based on an organic clover manuring system. Compared with cattle manure this system is not able to keep the humus content of soil on a stabil level, as world wide mega studies show. Looking to the climat influence a rising up in humus content is the challenge! What is the special quality of farm manure? What is the influence of the clover gras rotation?
Dr. König showd the special quality of the digestion system aof cattles compared with other animals: the possibility to convert straw and gras into manure. The function of cows in ecological agriculture is not only to produce milk and meet, but also to create this high quality manure! This is eveb an interesting question looking to the discussion of vegetarian or vegan farming without taking care of animals in the farm.

Looking back to the 1st meeting in Maribor we discussed the making of preparations and the compost. There is a big difference between the rules in Germany and Slovenia concerning the possibilities of storage of manure and compost.

Planing next meetings: the next dates are
  • 29./30. March 2014: Croatia
  • 30./31. August 2014: Denmark
  • September/Oktober 2014: Germany
  • March 2015: Croatia
  • May 2015: Slovenia - final meeting.

In the afternoon we visited a new biodynamic farm in Darmstadt (Hofgut Oberfeld). The farmer Thomas Göbel gave us an introduction into the history of this farm and the conversion to biodynamic agriculture. This farm is situated direct outside the border of the town surrounded three side by woods. It is a totaly public project, pushed in the beginning by many people from the town. In this year they got a new stabel for cattles. Chicken are hold on transportable stables on field.
