Recent legislative restrictions on the use of fertilizers and irrigation, and a quest for sustainable farming systems have drawn renewed attention to the functioning of the soil and the ecosystem services it provides. Soil biota play an important role in the provision of these ecosystem services, which may be influenced by grassland management. The two objectives of this thesis were 1) to gain insight into the effect of different grassland management measures on soil biota in sandy soils; and 2) to explore the effect of grassland management on the ecosystem services provided by soil biota. |

Fusarium graminearum är en av de viktigaste patogenerna på stråsäd och orsakar stora förluster i skörd över hela världen. Den mest odlade stråsäden i Sverige är höstvete. F. graminearum producerar både sexuella och asexuella sporer för spridning. Flera faktorer påverkar produktionen av dessa sporer. Stråbasröta orsakad av Fusarium-släktet är en ekonomiskt viktig sjukdom som kan ge avkastningsförluster på mellan 35% och 61%. I detta försök har ett biotest utvärderats för förhållandet mellan inokulummängd och sjukdomsutveckling hos stråbasröta orsakad av F. graminearum. Sjukdomsindex visade på en tydlig trend med ökande symptom med ökad konidiekoncentration medan torrviktsresultatet inte uppvisade en lika tydlig trend. Biotestet ger ett relativt snabbt... |

Truffles are rarely found in Finland, in spite of recent breakthroughs. In 2006, we initiated an effort to explore the possibility, and feasibility of truffle cultivation in Finland. This effort started by establishing the first truffle orchard in Juva. By 2016, we planted roughly 10 000 tree seedlings in 33 orchards. The results of our work indicated that even a boreal Finnish area is suitable for the sustainable organic production of truffles, and it appears that Tuber aestivum is a promising truffle species for future truffle orchards in northern conditions. Our results also show that restrictions caused by the Finnish winter climate and low soil temperatures can be overcome with proper soil and winter protection management. In conclusion, the selection... |

The aim of this study was to investigate the potentials and limitations in restoring soil suppressiveness in disturbed soils. Soils from three sites in UK and Switzerland (STC, REC, THE) differing in their level of suppressiveness to soil-borne and air-borne diseases were γ-irradiated and this soil matrix was re-inoculated with 1% (w/w) of either parent native soil or native soil from the other sites (‘soil inoculum’). Suppressiveness to air-borne and soil-borne diseases was quantified by means of the host–pathogen systems Lepidium sativum (cress)–Pythium ultimum, an oomycete causing root rot and seedling damping-off, and Arabidopsis thaliana–Hyaloperonospora parasitica, an oomycete causing downy mildew. Soil microbial biomass, activity and community... |

Soils suppressive to soil-borne diseases have attracted the attention of farmers and researchers for decades and many suppressive soils have been described. Microorganisms and soil microbial communities involved in suppressiveness have been studied intensively, but the underlying mechanisms are still not well understood. Suppressiveness to soil- as well as air-borne diseases has been shown to be highly site-specific. We will review how suppressiveness can be influenced by agricultural practices. Suppressiveness destroyed e.g. by steam sterilisation of soils could only be partially restored on the short-term by re-inoculation of soils, and the success of re-inoculation depended on the soil matrix as well as on the inoculum used. Long-term management (e.g.... |

The impact of soil type, long-term soil management, and short-term fertility input strategies on the suppressiveness of soils against soil-borne (Ocimum basilicum – Rhizoctonia solani, Lepidium sativum – Pythium ultimum) as well as air-borne (Lycopersicon esculentum – Phytophthora infestans, Arabidopsis thaliana – Hyaloperonospora parasitica) diseases was studied. Soils from field trials established in five European sites with contrasting pedo-climatic conditions were examined. Sites included (i) a long-term management field trial comparing organic and conventional farming systems (DOK-trial, Therwil, Switzerland) (ii) a short-term fertility input field trial comparing mineral and organic matter fertilisation regimes (Bonn (BON), Germany) (iii) two... |

TaqMan-based quantitative PCR (qPCR) assays were developed to study the persistence of two well-characterized strains of plant growth-promoting rhizobacteria (PGPR), Pseudomonas fluorescens Pf153 and Pseudomonas sp. DSMZ 13134, in the root and rhizoplane of inoculated maize plants. This was performed in pot experiments with three contrasting field soils (Buus, Le Caron and DOK-M). Potential cross-reactivity of the qPCR assays was assessed with indigenous Pseudomonas and related bacterial species, which had been isolated from the rhizoplane of maize roots grown in the three soils and then characterized by Matrix-Assisted Laser Desorption Ionization (MALDI) Time-of-Flight (TOF) mass spectrometry (MS). Sensitivity of the qPCR expressed as detection limit of... |

Einleitung • Bodenbürtige Krankheiten verursachen grosse Schäden und sind schwierig zu kontrollieren. • Kompost-Zugabe kann Druck durch bodenbürtige Krankheitserreger reduzieren • ABER: Nicht jeder Komposteinsatz ist erfolgreich. • Möglicher Grund ist die sich während des Kompost-Reifeprozesses laufend ändernde mikrobielle Zusammensetzung. • Es ist weitgehend noch unbekannt, welche mikrobiellen Konsortien wichtig für die suppressive Wirkung von Komposten sind. |
