Analysis of facilities in OFF research in participating countries of CORE Organic Organic Eprints
Nykänen, Arja; Canali, Stefano.
Report lists the following research facilities: research farms, experimental fields, on-farm studies, networks, animal research facilities, leaching fields and long-term experiments. Other facilities like facilities for laboratory analyses, food processing, greenhouses, climate chambers and growth cabinets are left out from this analysis, because they are seldom exclusively used for OFF research and because their use for OFF research does not require particular characteristics. On the other hand, when required, these facilities can easily be converted to OFF research.

Assessing the sustainability of EU dairy farms with different management systems and husbandry practices Organic Eprints
Leach, Katharine; Gerrard, Catherine L; Kudahl, Anne Braad; Nykänen, Arja; Vaarst, Mette; Weissensteiner, Roswitha; Padel, Susanne.
The EU funded SOLID project supports research which will contribute to the competitiveness of organic and low input dairy systems, and increase their sustainability. There are many aspects of the sustainability of dairy farms, relating to economic, environmental and social dimensions, and methods of animal husbandry can affect all of these. A UK spreadsheet based tool for rapid assessment of the whole farm was adapted for application on a range of organic and low input dairy farms across the EU. This tool was used to assess approximately ten organic dairy farms in each of four EU countries. Data on farm management practices collected in face to face interviews with farmers were entered and the tool then calculated a composite score for each of 11 separate...

EXPERIENCES ON DIFFERENT TYPES OF ON-FARM RESEARCH IN EASTERN FINLAND Organic Eprints
Nykänen, Arja; Kurki, Päivi; Rinne, Marketta.
In Finland, as well as in many other countries, on-farm research is becoming more and more common. The reasons are many-fold. Agricultural research stations are closed down due to economical constraints and researchers want to have ‘real data’ from the farms. Advisors see on-farm research as a new and efficient tool to show farmers good practices in their production. In addition, for farmers it is an attractive way of testing suitable farming practices in the environment of their own farm.

Faecal microorganisms in run-off from cattle farming Organic Eprints
Uusi-Kämppä, Jaana; Huuskonen, Arto; Kuisma, Miia; Nykänen, Arja; Heinonen-Tanski, Helvi.
Numbers of faecal microbes (faecal coliforms, enterococci, sulphite-reducing clostridia and coliphages) were determined in run-off waters from cattle farms in 1998-2005. Water samples were collected from drain wells and open ditches adjacent to exercise yards and forested feedlots for cattle, a grass field with slurry applications and a pasture with buffer strips. The indicator numbers were the highest in run-off waters from asphalt exercise yards while the figures were even 100-fold smaller in waters from a bark covered yard. In the forested feedlots, where cattle were fed for the winter months or all the year round, the indicator numbers were as high as the ones in a grass field with slurry applications or a pasture. There was a severe risk of...

Field-scale spatial variation in yields and nitrogen fixation of clover-grass leys and in soil nutrients Organic Eprints
Nykänen, Arja; Jauhiainen, Lauri; Kemppainen, Jukka; Lindström, Kristina.
Biological nitrogen fixation (BNF) plays a crucial role in organic farming and red clover (Trifolium pratense) is cultivated widely in boreal grasslands for BNF. A geostatistical method, model-based kriging, was used to determine the spatial variation in yield, clover content and BNF of clover-grass leys as well as soil chemical properties throughout two fields in 2004-2006. Based on this variation, principal component analysis (PCA) was used to determine the similar patterns of variation. On one location, total dry matter yields of the leys decreased over three production years from 9 700 to 4 100 kg ha-1, clover content from 53 to 26% and BNF from 150 to 40 kg N ha-1, whereas on the other location the yields increased from 6 500 to 7 100 kg ha-1, clover...

Fitting legumes into an established farming system Organic Eprints
Stoddard, Fred; Nykänen, Arja; Lizarazo, Clara.
Legume crops are an important part of healthy crop rotations. They offer more than just the harvested part: residual N, healthy soil, broken cereal disease cycles, ecological services. In 10 years 10 % of the arable land of Europe could be under legumes to meet our needs for livestock feed. Increased production of legumes will: Provide local feed, reduce international nitrogen imports and other "feed miles". Contribute biologically fixed nitrogen to energy crops as well as mainstream crops. Increase yield and quality of following crops. Add diversity to farm income streams.

Legumes in Finnish agriculture: history, present status and future prospects Organic Eprints
Stoddard, Frederick L.; Hovinen, Simo; Kontturi, Markku; Lindström, Kristina; Nykänen, Arja.
Legumes are important in world agriculture, providing biologically fixed nitrogen, breaking cereal disease cycles and contributing locally grown food and feed, including forage. Pea and faba bean were grown by early farmers in Finland, with remains dated to 500 BC. Landraces of pea and faba bean were gradually replaced by better adapted, higher quality materials for food use. While grain legumes have been restricted by their long growing seasons to the south of the country, red, white and alsike clovers are native throughout and have long been used in leys for grazing, hay and silage. Breeding programmes released many cultivars of these crops during the 1900s, particularly pea and red clover. A.I. Virtanen earned the 1945 Nobel Prize in Chemistry for his...

Nitrogen dynamics of organic farming in a crop rotation based on red clover (Trifolium pratense) leys Organic Eprints
Nykänen, Arja.
In agricultural systems which rely on organic sources of nitrogen (N), of which the primary source is biological N fixation (BNF), it is extremely important to use N as efficiently as possible with minimal losses to the environment. The amount of N through BNF should be maximised and the availability of the residual N after legumes should be synchronised to the subsequent plant needs in the crop rotation. Six field experiments in three locations in Finland were conducted in 1994-2006 to determine the productivity and amount of BNF in red clover-grass leys of different ages. The residual effects of the leys for subsequent cereals as well as the N leaching risk were studied by field measurements and by simulation using the CoupModel. N use efficiency (NUE)...

On-farm estimation of clover content of mixed swards Organic Eprints
Nykänen, Arja.
Estimation of clover content of mixed swards is difficult in practice. We are currently in the process of developing several on-farm methods for clover content estimaton. Yield samples with known area from several points of the field are separated for clovers and grasses and weighted. The clover content of yield (% in dry matter) can be calculated with formula y=23.90Ln(number of clover plants/m² in spring) - 18.759.
