Welcome to the website of the regional IHSS – Chapter of the Czech Republic

The Czech Chapter of the International Humic Substances Society was established at Brno University of Technology, Faculty of Chemistry by prof. Miloslav Pekař and Lubomír Rákos in 2008. Members of the Czech chapter of IHSS organize meetings regularly and they resolve the issues related to the research and applications of humic substances. The aim of this website is to introduce of humic substances to the public. The main emphasis is given especially to their behaviours, effects, issue of standardization of humic products.

The Czech chapter of IHSS has 15 members in 2016. This organization is formed mainly by the scientists from different Czech scientific institutions:


  • Brno University of Technology, Faculty of Chemistry, Brno, Czech Republic
  • Faculty of Agrobiology, Food and Natural Resources, Prague, Czech Republic
  • Mendel University in Brno, Brno, Czech Republic
  • Research Institute for Fodder Crops, Ltd. Troubsko, Czech Republic
  • University of Pardubice, Pardubice, Czech Republic
  • AMAGRO s.r.o., Prague, Czech Republic

Contacts on the members of IHSS-Czech are here. 


Czech chapter (inter)national meeting 2022

Meeting of the Czech chapter and others interested in humics, including foreigners, in 2022 took part again in Valtice, a small town in the South Moravian region of the Czech Republic, on April 29, 2022. The meeting was located in the Centre of Excellence operated by The National Wine Centre (https://www.vinarskecentrum.cz/en/) and in the Secondary Winery School Valtice (https://www.svisv.cz/). The meeting was traditionally supported and sponsored by Amagro (http://amagro.com/amagro.html) and Humatex (http://www.humatex.cz/) companies. About 40 attendees were present from both academic and industrial sectors including guests from Germany or Slovakia.

 The meeting was opened by Miloslav Pekař (Brno University of Technology), Czech national coordinator, and Lubomír Rákos, director of Amagro company. The first lecture was run remotely by Jiří Smilek (Brno University of Technology) who overviewed results of his young researcher project supported by IHSS, particularly from the area of the effect of blocking carboxyl groups on humic acids on their interaction properties. Barbora Badalíková (Research Institute of Fodder Crops) talked about importance of organic matter for soil quality, especially on experimental experience gained on trials from an erosion-damaged locality and on benefits of applying inter-crops.  Michal Kalina (Brno University of Technology) presented results of a GAČR (Czech Science Foundation) project focused on the fate of biochar applied to soil from the viewpoint of physical chemistry. Miloslav Pekař informed on a publication suggesting an alternative approach to study of the climate change links to soil organic matter and related suggestion on the cooperation between research organizations and agricultural farms or companies. Jan Kowolowski followed by Lubomír Varga (both from the Secondary Winery School) referred about their new experience with the application of Lignohumate MAX, Lignoactivator and Vitalic in vineyard, including their combinations with standard vinicultural sprays, and their effects on the characteristics of both harvested grapes and wine produced from them. The wine samples were provided for tasting and evaluation by the participants of the meeting. 

The afternoon session was opened by Zora Marková (Amagro) and her summary of 5-year results of lignohumates application used in vineyards, regeneration of “exhausted” soil, and in combinations with Roundup. Uwe Böhm (Agrostim, Germany) spoke about a complex, interdisciplinary care of soil, about “regenerative agriculture”, using both products of animal farming (slurry, manure) and compost, or lignohumates, and especially their combinations. Ladislav Menšík (representing a team from Crop Research Institute, Prague and station in Jevíčko and Mendel University in Brno) presented an overview of monitoring of the state of soil organic matter at agricultural companies in Boskovice groove and Drahanská highlands. He stressed the principal role of combined mineral and organic fertilization. Stanislav Janošík (STIMAP, Slovakia) summarized methods of controlled application of lignohumate preparations based on genetic characteristics of specific crop and on vegetation type. He pointed to the importance of autumn treatment. At the end, Miloslav Pekař informed on IUPAC view on synthetic humic substances which were selected of this organization among ten “emerging technologies” in chemistry of the year 2021.

 The meeting continued traditionally by dinner in the representative wine cellars of the winery school, further discussions, tasting school wines, and singing with a traditional Moravian folk cymbalo band.
