Cost and energy evaluation of organic cauliflower in sole crop and living mulch systems Organic Eprints
Ortolani, Livia; Kristensen, Hanne L.; Campanelli, Gabriele; Bavec, Martina; Bavec, Franc; von Fragstein, Peter; Bergmam, Astrid; Leteo, Fabrizio; Canali, Stefano.
This paper presents the findings of an assessment aimed to evaluate, in terms of cost and energy consumption, the introduction of living mulches in different organic vegetable systems producing cauliflower. The study was carried out in three European countries (IT, SLO and DK) in the frame of the InterVeg project (Core Organic II). The achievements demonstrated that, in economic terms, farmers’ choice of a specific technique, like living mulch instead of sole cropping, can be influenced by two key elements: human labor and fossil fuel consumption. Different organic systems have a different proportion in using the two inputs depending on the specific farm strategy.

Cover crop mulches and no-till maize Organic Eprints
Bortolussi, Stefano.
In a Northern Italian context, a field pea cover crop was tested as mulch for the maize crop. The roller crimper effectively terminated the cover crop (15 t per ha of wet biomass). However, the mulch did not last long enough, probably due to a narrow C/N-ratio and biologically active soil. The maize plants did not have enough time to develop and shade the entire soil surface. Weeds started to sprout through the decomposing mulch. For the test conditions, this cover crop has proven unsuitable as a long-lasting mulch to control weeds. No fertilization and no irrigation were applied. The maize yields amounted to about 5 t per ha. Practical recommendations • The cover crop needs to be sown as accurately as the main crop. Poor cover crop stands do not...

COVER CROPS AND MULCHES INFLUENCE WEED COMMUNITY CHARACTERISTICS IN STRIP TILLED TOMATO (Solanum lycopersicon L.) Organic Eprints
Campiglia, Enio; Mancinelli , Roberto; Radicetti, Emanuele.
The aim of this poster is to investigate the effects that cover crop species and their residues may have on weed community composition in a winter cover crop-tomato sequence. Experiments were carried out at the experimental farm of Tuscia University from 2011 to 2013. The treatments consisted in: (i) 5 soil managements [three winter cover crop species (hairy vetch, phacelia, and white mustard), a winter fallow soil mulched with barley straw before tomato transplanting, and a winter fallow tilled before tomato transplanting (conventional)}; (ii) 2 levels of nitrogen fertilization applied on tomato [0 kg of N ha-1 (N0) and 100 kg of N ha-1 (N100)]; (iii) 2 levels of weed management applied on tomato [weed-free (WF) and weedy (We)]. Cover crop residues...

Cover crops in cereals – better companions than weeds? Organic Eprints
Salonen, Jukka; Zarina, Livija; Melander, Bo.
Cover crops have gained popularity in cereal cropping now that they are one of the subsidized options in agri-environmental schemes of the EU. Several studies on cover/catch crops affecting nutrient leaching have been published but less information is available concerning their applicability for weed management. In our opinion, combinations of crop and cover crop types as well as crop sequencing conform IPM principles and optimize weed management. The PRODIVA project (ERA-Net Core Organic Plus Action, www.coreorganicplus.org) aims at identifying weed community associations with most common crop types in organic crop production systems. We will clarify the characteristics and relative competitiveness of cover crops providing strong weed suppression without...

Creeping thistle - Successful control in organic farming Organic Eprints
Dierauer, Hansueli; Kranzler, Andreas; Ebert, Ulrich.
In recent years, the creeping thistle has become a problematic weed, especially for organic arable farms with good soils. Wherever it grows, it is competing with crops for water and nutrients. Once established, the thistle can only be reduced to a tolerable density with a lot of patience. So far, there is no patent remedy for its control on organic farms. By abiding certain rules of plant cultivation in combination with direct methods, the thistle can be effectively controlled.

Crop agronomy in organic agriculture Organic Eprints
von Fragstein und Niemsdorff, P.; Kristiansen, P..
Organic crop husbandry is based on practices outlined in the various organic standards that have been developed and documented in many countries. The most widely recognised organic standards are those published by the International Federation of Organic Agriculture Movements (IFOAM 2002). Organic farming methods emphasise the use of internal on-farm inputs rather than externally sourced inputs to achieve essential soil fertility, nutrient management and plant protection goals. Self-regulation within an agroecosystem, multi-year management cycles and a focus on prevention rather than reaction, are key principles in organic farming that underpin organic plant production.

Crop diversification and weeds Organic Eprints
PRODIVA will produce the information required for a better utilization of crop diversification for weed management in North European organic arable cropping systems. The goal is not to eradicate weed problems, which is unlikely to happen in any arable farming system, but to maintain a diversified and manageable weed flora that can support beneficial organisms. The partners in PRODIVA will focus on synthesizing knowledge from terminated and running research projects including new experiments on crop rotation, cover crop growing, and crop and variety mixtures. This will provide a coherent picture and help closing important knowledge gaps. It will be investigated whether detrimental weed communities can be disrupted through strategic diversification of crop...

Crop diversification and weeds Acronym: PRODIVA Organic Eprints
Melander, Bo; Gerowitt, Bärbel; Salonen, Jukka; Verwijst, Theo; Lundkvist, Anneli; Zarina, Livija; Hofmeijer, Merel A.J.; Sylwia, Kaczmarek; Roman, Krawczyk.
Diversification of crop sequences (WP 1): Perennial weed species can be managed when cover crops / green manure crops are included in the crop sequence but interventions must be species dependent, e.g. Elytrigia repens can be promoted by green manures because they prevent post-harvest cultivations. Cirsium arvense and Sonchus arvensis are two perennials that can be controlled by full-season grass-clover subjected to regular mowing for green manuring purposes and this measure has immediate application. Cover crops for diversification (WP 1):  Fast growing cover crops producing copious biomasses are generally useful for the suppression of weeds but need to be abandoned when severe infestations of Elytrigia repens require post-harvest cultivations for...

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...

Crop diversity - a crucial remedy for weed management in organic cropping Organic Eprints
Salonen, Jukka; Zarina, Livija; Melander, Bo.
A wide variety of crop species in crop rotations has turned out an essential means to obtain diversification in organic cropping systems. Moreover, the potential of cover crops to assist the main crop in weed suppression has been studied in Denmark, Finland and Latvia. Long-term field experiments in Denmark and Latvia demonstrated that crops with different life cycles and life spans in crop sequence resulted in a relatively low and manageable pressure of annual weeds. The study was part of the PRODIVA project (Core Organic Plus) in which crop diversification for better weed management has been studied and presented in the 18th EWRS Symposium.

Crop rotation and its ability to suppress perennial weeds Organic Eprints
Askegaard, Margrethe.
Weed-suppressing crop rotations are essential for sustainable organic arable farming. Preventing spread of perennial weeds will increase crop yields and quality. The tool is a factsheet created for all organic farmers as we all need renewed knowledge on weed-suppression and crop rotation from time to time. The factsheet provides practical recommendations on crop selection and composition of crop rotations in accordance to weed competitiveness and nitrogen demand. An appropriate combination of crops and green manures, designed specifically for the conditions and needs of individual fields, prevents spread of perennial weeds. The factsheet doesn’t only focus on prevention but also provides recommendations in case of high weed pressure. Example: Do not sow...
