Pathogenicity of different Fusarium species on six arable crop species in Finland
Hautsalo, Juho; Jalli, Marja; Heinonen, Ulla; Latvala, Satu
Agricultural and food science : 3 (Scientific Agricultural Society of Finland, 2025)
In cereals, Fusarium species composition and associated mycotoxin risks are well studied in the Nordic countries, but the interactions between Fusarium populations and the legume crops faba bean and field pea, and the increasingly cultivated new crops such as maize and oilseed hemp, are unrevealed. In this study, two-year field experiments were carried out with spring wheat, oat and and the above-mentioned crops on small demonstration plots in 10 different fields in Central Finland. The aim was to analyse the severity of symptoms and prevalence of Fusarium species from the root and stem tissues of the field plants. While the legumes exhibited the most symptomatic plants, the prevalence of Fusarium species and symptoms in the samples varied considerably between the fields, F. avenaceum and F. equiseti being the most frequently detected species. In addition, the germination, growth and symptom development from Fusarium inoculated seeds of these arable crop species were examined in greenhouse conditions. F. graminearum, F. culmorum, and F. avenaceum were the most pathogenic Fusarium species in these experiments comparing up to 105 Fusarium isolate x crop species combinations.

Journal of dairy science : 7 (Elsevier, 2025)
Prolonged cow-calf contact (CCC) is of growing importance to the dairy sector due to increasing societal interest, implementation of CCC on farms, and research efforts. Incorporating CCC into dairy systems may be a polarizing change for academics and farmers. However, by considering the challenges with curiosity, including those mutual to CCC and non-CCC systems, there may be an opportunity to collectively improve the management of dairy animals. The aim of this review was to describe current issues and constraints in CCC, propose opportunities to advance knowledge of CCC, and inspire forward-thinking questions for dairy systems. There are known challenges for CCC implementation, such as research reproducibility (e.g., suitable controls, validity types) and on-farm application (e.g., farmer perspectives, policies, and corporate standards). To facilitate practical solutions for farmers wanting to adopt CCC we need research describing the effects of CCC systems on animal health and behavior. Already researchers have begun to explore cow and calf performance and health, methods for decreasing stress at weaning and separation (e.g., duration of contact, gradual weaning), foster cows, and opportunities for positive animal welfare in CCC systems (e.g., affiliative and play behavior). However, because dairying takes place in a complex system, changes may affect different facets of the system's sustainability. We suggest that the development of CCC systems should happen in dialog with stakeholders. Cow-calf contact is an uncommon practice in dairy systems and exists in different contexts; thus, there are many questions to address before advice can be given to interested dairy stakeholders. Perhaps, these CCC-related questions are an invitation to contemplate how we want dairy systems to look like in 30 years.

Luonnonvara- ja biotalouden tutkimus : 82/2025 (Luonnonvarakeskus, 2025)
This report contains information on the nutrient recycling potential in the Baltic Sea Region. The information was collected with two different methods: a Eurostat-based method for all countries and national data collection separately for each country. The recyclable biomasses considered were livestock manure, sewage sludge, municipal biowaste and different industrial side streams. The Eurostat-based data is uniform for all countries and gives indication of nutrient recycling potential in the Baltic Sea Region on NUTS2 level of spatial distribution. However, it fails to consider national differences in the nutrient contents of the recyclable biomasses and the NUTS2 level is too coarse to identify regions of nutrient surplus or deficit in many of the countries. National data collection can provide more detailed spatial resolution for at least some of the recyclable biomasses and offer nationally more accurate data on the nutrient contents. However, the data is scattered into various sources and includes gaps and uncertainties which should be improved by developing the national data collections. To monitor the nutrient recycling potential and the need for nutrients especially in agricultural production, the regions of surplus and deficit should be nationally estimated by comparing the amount of nutrients to be recycled and the fertilization need within each country and region. This report offers an example of such a calculation for Finland. Information on the nutrient recycling potential is a basis for planning, promoting and implementing nutrient recycling measures. Thus, it should be organized country-specifically by designating responsible organization(s), resourcing them sufficiently for a regular updating of the data, and including an analysis of the current status of the use of the recyclable biomasses. The monitored information highlights the progress of nutrient recycling and identifies development needs. Methodology for the monitoring process should still be developed further within the scientific community.
Turvetta korvaavat vaihtoehtoiset kasvualusta- ja kuivikemateriaalit : Esiselvitys
Silvan, Niko; Virkkunen, Elina; Honkanen, Henri M; Högel, Heidi; Kivioja, Johanna; Näkkilä, Juha; Muilu-Mäkelä, Riina; Silvan, Niko (toim.); Virkkunen, Elina (toim.)
Luonnonvara- ja biotalouden tutkimus : 85/2025 (Luonnonvarakeskus, 2025)
Selvitys on osa Turvevapaa ruokaketju -hanketta, jota koordinoi Seinäjoen ammattikorkeakoulu ja jota rahoitetaan EU:n Just Transition Fund (JTF) -rahastosta. Hankkeen taustalla on turvetuotannon alasajo Etelä-Pohjanmaalla, mikä vapauttaa merkittäviä määriä turvemaata käyttöön ja vaikuttaa suoraan alueen elintarviketuotantoon, erityisesti eläintiloihin ja puutarhatuotantoon, joissa turve on ollut keskeinen kuivike- ja kasvualustamateriaali. Suomessa tuotettiin vuonna 2023 noin 1 320 000 m3 kuiviketurvetta erityisesti broileri-, nauta- ja hevostilojen kuivikkeeksi. Kasvualustojen osalta Suomessa käytetään vuosittain noin 170 000–200 000 m³ kasvuturvetta kasvihuonetuotannossa ja noin 40 000 m³ metsätaimituotannossa. Turpeen rinnalle on tullut uusia materiaaleja, mutta niiden osuus on vielä pieni. Tarve uusille kestäville ja kotimaisille turpeen vaihtoehdoille on suuri. Tämän selvityksen tarkoituksena oli koota yhteen tietoa turpeelle vaihtoehtoisista materiaaleista. Selvityksessä on perehdytty alalla tehtyyn tutkimukseen ja tuotekehitykseen ja kartoitettu potentiaalisia turvetta korvaavia materiaaleja keskittyen kosteikoilla viljeltävissä oleviin ja etenkin Etelä-Pohjanmaalla tuotettavissa oleviin materiaaleihin. Selvityksessä on pohdittu materiaalien tuotannon, käyttöönoton ja käytön ongelmakohtia ja pullonkauloja ja mitä näille mahdollisesti olisi tehtävissä. Lisäksi selvityksessä tarkastellaan vaihtoehtoisten materiaalien viljelyä ja omassa osiossaan kosteikkoviljelyn aloittamisen toimenpiteitä. Materiaaleissa on keskitytty ruokaketjuun, erityisesti kuivike- ja kasvualustamateriaaleihin, mutta tarkastelussa ovat lisäksi mukana myös muut mahdolliset arvoketjut. Vaihtoehtoisten materiaalien käyttöönottoa hidastavat etenkin saatavuusongelmat, epätasalaatuisuus ja jalostustarpeet. Jalostuksella voidaan parantaa materiaalien hygieenisyyttä ja käyttökelpoisuutta ilman merkittävää ilmastokuormaa.
