Crop diversification for weed management in North European organic arable cropping systems. Introduction to the study of international research-network on diversification and weed management: PRODIVA. Organic Eprints
Hofmeijer, Merel A.J.; Gerowitt, Bärbel; Krawczyk, Roman; Salonen, Jukka; Verwijst, Theo; Zarina, Livija; Melander, Bo.
The international research network PRODIVA aims to improved utilization of crop diversification for weed management in northern European organic arable cropping systems. The over-all aim is to support organic agriculture for the exploitation of crop diversification methods to improve weed management and still maintain a diverse weed flora. Hypothesized is that crop diversification can improve weed management while ensuring a diverse weed flora by the employment of: (I) pertinent crop sequencing that mitigates noxious weed species (II) improved cover crop establishment with selected competitive cover crop species (III) crop mixtures utilizing the resources better than sole crop species resulting in more weed suppression (IV) variety mixtures exerting a...

Gerowitt, Bärbel; Hofmeijer, Merel A.J.; Melander, Bo; Sonderskov, Mette; Krawczyk, Roman; Kaczmarek, Sylvia; Salonen, Jukka; Verwijst, Theo.
To organize and manage the dissemination process has become a general task within international projects. Within the project PRODIVA (Crop diversification and weed management) we organized these chains as returning cascades between practice (advisors and farmers) and scientists in the Baltic area. A network of farmers was created in each participating region. We collected and used practical knowledge about dominating weed species in Organic spring cereal production. This data can be compared with monitored weeds in the regions. Together with the monitored weeds management data was collected on-farm. Relating this data to the results of experimentally investigated crop diversification tools, being subsidiary crops in the rotation, crop mixtures and variety...

Hofmeijer, Merel A.J.; Krawczyk, Roman; Kaczmarek, Sylvia.
Chwasty stanowią źródło różnorodności biologicznej terenów rolniczych, tworzą siedliska i są źródłem pokarmu dla innych organizmów, jednakże z perspektywy produkcji �w rolnictwie ekologicznym zawsze stanowiły duże wyzwanie. Kilka grup gatunków chwastów, ze względu na specyficzne gospodarowanie ekologicznym systemem rolniczym, naturalnie się dostosowało. Może to oddziaływać mocno konkurencyjnie na rośliny uprawne i wymagać dużej ilości nakładów w usunięciu i/lub ograniczeniu ich rozprzestrzeniania. W niniejszej ulotce opisano najbardziej uciążliwe gatunki chwastów w zbożach jarych uprawianych �w gospodarstwach ekologicznych w rejonie Morza Bałtyckiego, w oparciu o istniejącą literaturę oraz informacje dostarczone przez służby doradcze.

Geographical distribution of challenging weed species - Current knowledge in organic arable farming in the Baltic sea region Organic Eprints
Hofmeijer, Merel A.J.; Melander, Bo; Krawczyk, Roman; Verwijst, Theo; Zarina, Livija; Salonen, Jukka; Gerowitt, Bärbel.
They create a great source of agro biodiversity, generating habitats and food sources for other organisms; yet weeds have always posed the greatest challenge in Organic Agriculture from the perspective of production. Because of the specific agricultural management of this farming system, several groups of weed species have naturally adjusted. These can be highly competitive to the crop, acquire high inputs to remove and/or spread rapidly. In this leaflet we will describe the most challenging weed species in organic spring sown cereals in the geographical area of the Baltic sea, based on existing literature and information provided by extension services. We will show and discuss their distribution from country to country and propose a classification...

Problematic weed species in organic arable agriculture around the Baltic Sea - An expert database Organic Eprints
Hofmeijer, Merel A.J.; Melander, Bo; Krawczyk, Roman; Salonen, Jukka; Verwijst, Theo; Zarina, Livija; Gerowitt, Bärbel.
Weeds are a perpetual challenge in Organic agriculture. However, they serve multiple ecosystem services and a low competitive weed cover can be tolerated. Adding to this, is the fact that only a few species prove problematic for both the crop and the farmer. The international PRODIVA project researches the effect of crop diversity strategies on the diversity of weed communities, hypothesizing that by increasing the weed diversity, the development of problematic weeds will mitigated. A preparatory study was conducted to list the most problematic weed species in spring sown cereals in the countries involved with PRODIVA. For this a literature review was conducted in all participating countries, collecting local sources including grey literature. This was...

Implications - Specific annual and perennial weeds are a perpetual challenge in the process of tuning up sustainable Organic production. To utilize the perspective of agro-biodiversity would both improve crop yields as well as conserve the ecosystem services of this agriculture system. The successful use of crop diversity strategies provides an additional tool in the toolbox of the farmers, giving them a) an overview of problematic weed species and b) the opportunity to plan their crop diversity based weed management over the course of years in the future.

PRODIVA, Crop species mixtures for weed suppression: Deliverability No. D2.3 Technical report Organic Eprints
Verwijst, Theo; Lundkvist, Anneli; Pers Berglund, Anna; Krawczyk, Roman; Kaczmarek, Sylvia.
The aim of the studies performed in PRODIVA working package 2 was to assess the weed suppressive ability of crop mixtures (spring barley + peas) compared to ability of pure crops to suppress weeds. The work was done by means of field trials in which natural weed populations were used while controlled experiments were used with Elytrigia repens or Sinapis alba as a model weeds. Over a period of three years, 5 field experiments and 9 experiments under controlled conditions were performed in Poland and Sweden. In all experiments, performance was assessed in terms of the crops ability to compete against weeds (AC). The ability to withstand competition from weeds (AWC) and the relative weed biomass in the intercrop, compared to weed biomass in the sole...

The main reason for controlling weed abundance in agricultural crops is the risk for qualitative and quantitative reductions in crop yields. Although there are no simple standard solutions available for weed control in organic agriculture, however, some cultural practices—in particular, undersow in spring cereals—can be critical components of weed management. To study this thesis, specific research has been carried out in the CORE Organic Plus PRODIVA project in six northern European countries—Denmark, Finland, Germany, Latvia, Poland & Sweden. Density of weed species were assessed in 109 organic fields situated in different agro–ecological conditions of region. The highest number of weed species fixed in surveyed fields was 93 (in Denmark). The most...
