The soil microbial community plays a key role in nutrient cycling, affecting access of roots to P, as well as mobilization and mineralization of organic P (Porg). This thesis aimed to better understand the potential of cover crops to enhance plant-soil-microbe interactions to improve the availability of P. This dissertation consists of a meta-analysis of and two field experiments. The used methods showed that microbial P, the activity of P-cycling enzymes and PLFAs increased under cover crops, indicating an enhanced potential for organic P cycling. Gram- positive and Gram-negative bacteria, and to a lesser extent also arbuscular mycorrhizal fungi, increased their abundance with cover crops. However, saprotrophic fungi could benefit most from the substrate input derived from cover crop roots or litter. Enzyme-stable Porg shifted towards pools of a greater lability in the active soil compartments (rhizosheath and detritusphere). The effects of agricultural management, such as cover crop species choice and tillage, were detectable, but weaker compared to the effect of the presence of cover crops. With the obtained results, the research aims of this thesis could be successfully addressed. We were able to confirm that cover crops have the potential to improve main crops\u0092 access to P. Furthermore, we presented and discussed three pathways of P benefit. In the plant biomass pathway, P is cycled through cover crop biomass and becomes available for the main crop upon litter decomposition. The microbial enhancement pathway describes how the cover crop\u0092s interaction with soil microbes increases their abundance and activity, thereby increasing the availability of Porg. Some cover crop species seem to be capable of utilizing a biochemical modification pathway, where changes in the sorption capacity of the soil result in a greater quantity of plant-available phosphate. However, the latter pathway was apparently not important in the crop rotations used in our field experiments. The data also allowed us to characterize ways in which plant-soil-microbe interactions under cover crops affected the relationship of soil microbial functions to the enzymatic availability of Porg pools. Cover crops increased the abundance and activity of microbes, especially fungi, as well as microbial P. This enhancement in P-cycling potential shifted Porg toward pools of greater availability to added enzymes. However, the relation between enzymes and Porg pools is complex and is possibly affected by soil P composition and other site characteristics, indicating the need for further research in this area. Finally, we elucidated how the choice of cover crop species and agricultural management can shift the relative importance of the pathways for the P benefit of the main crop, while site-specific management allows farmers to adapt to local conditions and to optimize the functions of their agroecosystems. In conclusion, our results indicate that the pathways of cover crop derived P benefit take place simultaneously. We confirmed the potential of cover crop biomass for the cycling of P, and we suggest that our observed increases in the availability of soil Porg are related to microbial abundance and activity. The interactions of cover cropping and tillage indicate also that P benefit can be optimized by management decisions. Finally, these new insights into soil phosphorus cycling in agroecosystems have the potential to support further development of more sustainable agricultural systems. Phosphor (P) ist einer der wichtigsten limitierenden Naehrstoffe fuer das Pflanzenwachstum in der Landwirtschaft. Bodenmikroben spielen eine Schluesselrolle in Naehrstoffkreislaeufen, beeinflussen das Wachstum von Pflanzenwurzeln, die Mobilisierung sowie die Mineralisierung von organischem P (Porg) und somit den Zugang zu P. Das Ziel dieser Dissertation war die Einschaetzung des Potentials von Zwischenfruechten zur Verbesserung der Interaktionen im System Pflanze-Boden-Mikroben und einer dadurch moeglichen Steigerung der P-Verfuegbarkeit fuer die Hauptfruechte.  Diese Dissertation umfasst drei wissenschaftliche Veroeffentlichungen: Eine Literaturrecherche und Meta-Analyse sowie zwei selbst durchgefuehrte Feldexperimente. Die verwendeten Methoden zeigten, dass Zwischenfruechte den P-Gehalt in der mikrobiellen Biomasse, die Aktivitaet von Phosphatasen und mikrobielle Fettsaeuremarker (PLFAs) erhoehen, was auf ein gesteigertes Umsatzpotential von organischen Phosphorverbindungen hindeutet. Die Abundanz von grampositiven und gramnegativen Bakterien, sowie in geringerem Umfang auch von arbuskulaeren Mykorrhizapilzen, wurde durch Zwischenfruechte erhoeht. Gleichwohl waren saprotrophe Bodenpilze die mikrobielle Gruppe, die am meisten von der Substratzufuhr der Wurzeln und Streu profitieren konnte. Stabiles P wurde in den aktiven Bodenzonen der Rhizosphaere und Detritusphaere in labilere Porg-Pools transformiert. Bewirtschaftungseffekte, wie die Wahl der Zwischenfrucht oder Bodenbearbeitung, waren erkennbar, aber wesentlich schwaecher ausgepraegt als der Zwischenfruchteffekt insgesamt.  Unsere Ergebnisse bestaetigen, dass Zwischenfruchtanbau zur Steigerung der P - Verfuegbarkeit fuer die Hauptfrucht fuehren kann. Darueber hinaus konnten wir fuer den P- Vorteil drei grundsaetzliche Wirkungspfade aufzeigen, die in aktiven Bodenraeumen stattfinden. UEber den Wirkungspfad \u0084Pflanzenbiomasse\u0093 wird P aus dem Boden in die Biomasse der Zwischenfrucht aufgenommen und waehrend der Zersetzung der Streu fuer die Hauptfrucht verfuegbar. UEber den Wirkungspfad \u0084mikrobielle Verstaerkung\u0093 steigert die Zwischenfrucht im Wurzelraum die Biomasse und Aktivitaet der mikrobiellen Gemeinschaft, wodurch diese die Verfuegbarkeit von Porg erhoehen kann. Durch den Wirkungspfad \u0084biochemische Modifikation\u0093 scheinen manche Zwischenfruchtarten in der Lage zu sein, ueber Wurzelexsudate die P-Sorption im Boden zu senken und dadurch den Anteil an pflanzenverfuegbarem Phosphat zu erhoehen.  Weiterhin ermoeglichen die erhobenen Daten die Diskussion, inwiefern mikrobielle Funktionen und die Mineralisierbarkeit von Porg zusammenhaengen und wie die Interaktionen von Pflanzen beeinflusst werden. Zwischenfruechte steigerten sowohl die Abundanz und Aktivitaet von Mikroben, als auch die Menge an P in der mikrobiellen Biomasse. Diese Potentialsteigerung des P-Kreislaufs steigerte die Verfuegbarkeit des Porg fuer zugefuegte Enzyme. Es muss bedacht werden, dass die Rueckkopplungen zwischen Enzymaktivitaet und verschiedenen Porg-Pools komplex sind. Diese haengen von den lokalen Eigenschaften des Bodens, wie etwa der Zusammensetzung des P-Vorrats, ab und sollten durch zukuenftige Studien geklaert werden.  Drittens zeigen unsere Untersuchungen, wie die Wahl der Zwischenfrucht und die der Bewirtschaftung (z.B. Bodenbearbeitung oder Fruchtfolge) die relative Gewichtung der verschiedenen Pfade des P-Vorteils fuer die Hauptfrucht beeinflussen. Standortangepasste Zwischenfruchtsysteme erlauben es Landwirt:innen, die Funktionen ihres Agrooekosystems hinsichtlich der lokalen Bedingungen zu optimieren.  Zusammenfassend bestaetigen unsere Ergebnisse, dass der P-Bedarf der Hauptfrucht ueber die Biomasse der Zwischenfrucht gedeckt werden kann und zeigen auf, dass die charakterisierten drei Pfade des P-Vorteils durch Zwischenfruchtanbau parallel stattfinden.

Different growth conditions and silvicultural treatments lead to an increased scatter in strength compared to what is expected from monoculture experience. The study (i) quantified the magnitude of variation in strength of European beech timber from stands of different composition and (ii) showed the impact of grading on the characteristic strength value of timber coming from those stands. Strength grading models and machine settings for hardwood tensile classes on over 900 European beech (Fagus sylvatica L.) boards were derived. One model used only the dynamic modulus of elasticity (Edyn), and a more complex model used a knot value in addition. Afterwards, 407 boards from pure beech stands as well as mixed stands of beech with Douglas fir (Pseudotsuga menziesii (Mirb.) Franco), Norway spruce (Picea abies (L.) Karst.), sessile oak (Quercus petraea (Matt.) Liebl.), and Scots pine (Pinus sylvestris L.) were graded and analyzed for their material properties from tension tests parallel to grain. Although a variance components analysis attributed only 4.2% of the variation to mixture, the ungraded timber showed significant strength differences between the pure and the beech-pine stands (65.2 versus 46.6\uffc2\uffa0MPa). The yield of the material graded to the highest class in a class combination was higher in pure beech stands. The required characteristic strength values were mostly met for boards from the pure stands; while boards from the beech-pine mixed stands hardly ever reached the required values. To reduce strength variation and guarantee reliable timber products, strength grading should consider the various growth situations in forests when sampling material for the derivation of settings.</p>", "keywords": ["690", "0106 biological sciences", "Original ; Wood Science & Technology ; Ceramics", " Glass", " Composites", " Natural Materials ; Manufacturing", " Machines", " Tools", " Processes", "ddc:630", "0401 agriculture", " forestry", " and fisheries", "04 agricultural and veterinary sciences", "15.

We conducted a meta-analysis of published field studies on cover crops and P cycling, focusing on plant-microbe interactions.

Compared with canola, wheat and barley had a higher specific root length and a greater root carboxylate release and they acquired as much P from sludge as from mineral P.

As microplastics may affect soil water content, this could exacerbate the well\uffe2\uff80\uff90known negative effects of drought on ecosystem functionality. Thus, functions including litter decomposition, soil aggregation or those related with nutrient cycling can be altered. Despite this potential interaction, we know relatively little about how microplastics, under different soil water conditions, affect ecosystem functions and multifunctionality.</p>  <p>To address this gap, we performed an experiment using grassland plant communities growing in microcosms.

The Scientific track will contribute to bridging not only scientists but also institutions and disciplines, and to linking more developed and less developed, rural and urban, research to extension, plant to animal, farm practices to world-wide problems and producer and consumers. Organic is a management system that requires a diversity of inputs from different disciplines, therefore, an international Congress is the best medium to blend them. The Scientific Track is organized with special efforts of the co-organizers, International Society for Organic farming Research (ISOFAR; www.isofar.org) and EGE University (Turkey; www.ege.edu.tr). Organic e-prints (www.orgprints.org) acted as the hub for collection, revision and maintaining of all the papers. There were 568 manuscripts and abstracts received for the Scientific Track. Abstracts were not evaluated since the authors were obliged to submit full papers. About 96 reviewers - 37 from Turkey and 59 from all over the world (ISOFAR network) - contributed to the review process (double-blind: 1 reviewer international, 1 reviewer Turkish, final assessment and decision by the scientific board). At least, 300 papers have been accepted. They are from 51 countries and represent the countries, were 87 % of the global organic farm land and 75 % of the global organic farms are located. It is obvious, that organic farming is practiced world wide (but less the 1 % of the total farm land is managed organically), the organic markets are mainly in the western world (Europe, North America, Japan: 94 %) and the research is mainly done in Europe (publication share in web of science: 84 %, at the 4th ISOFAR congress: 69 %). [...] The papers are ordered by countries (country of the first author), not by sessions or disciplines. These decisions are made to make the proceedings affordable (all volumes can be purchased individually) and to merge and bridge the world and not split by disciplines and sessions. You find search facilities (indexes) to find all papers by discipline, eprint-number, keywords or sessions in each volume. A download of the full proceeding is possible under the webpage of ISOFAR (www.isofar.org) and as individual papers under organic eprints (www.orgprints.org). Due to the fact that all papers together comprise 1,300 pages, the printed Proceedings are split into four volumes.

The soil microbial community plays a key role in nutrient cycling, affecting access of roots to P, as well as mobilization and mineralization of organic P (Porg). This thesis aimed to better understand the potential of cover crops to enhance plant-soil-microbe interactions to improve the availability of P. This dissertation consists of a meta-analysis of and two field experiments. The used methods showed that microbial P, the activity of P-cycling enzymes and PLFAs increased under cover crops, indicating an enhanced potential for organic P cycling. Gram- positive and Gram-negative bacteria, and to a lesser extent also arbuscular mycorrhizal fungi, increased their abundance with cover crops. However, saprotrophic fungi could benefit most from the substrate input derived from cover crop roots or litter. Enzyme-stable Porg shifted towards pools of a greater lability in the active soil compartments (rhizosheath and detritusphere). The effects of agricultural management, such as cover crop species choice and tillage, were detectable, but weaker compared to the effect of the presence of cover crops. With the obtained results, the research aims of this thesis could be successfully addressed. We were able to confirm that cover crops have the potential to improve main crops\u0092 access to P. Furthermore, we presented and discussed three pathways of P benefit. In the plant biomass pathway, P is cycled through cover crop biomass and becomes available for the main crop upon litter decomposition. The microbial enhancement pathway describes how the cover crop\u0092s interaction with soil microbes increases their abundance and activity, thereby increasing the availability of Porg. Some cover crop species seem to be capable of utilizing a biochemical modification pathway, where changes in the sorption capacity of the soil result in a greater quantity of plant-available phosphate. However, the latter pathway was apparently not important in the crop rotations used in our field experiments. The data also allowed us to characterize ways in which plant-soil-microbe interactions under cover crops affected the relationship of soil microbial functions to the enzymatic availability of Porg pools. Cover crops increased the abundance and activity of microbes, especially fungi, as well as microbial P. This enhancement in P-cycling potential shifted Porg toward pools of greater availability to added enzymes. However, the relation between enzymes and Porg pools is complex and is possibly affected by soil P composition and other site characteristics, indicating the need for further research in this area. Finally, we elucidated how the choice of cover crop species and agricultural management can shift the relative importance of the pathways for the P benefit of the main crop, while site-specific management allows farmers to adapt to local conditions and to optimize the functions of their agroecosystems. In conclusion, our results indicate that the pathways of cover crop derived P benefit take place simultaneously. We confirmed the potential of cover crop biomass for the cycling of P, and we suggest that our observed increases in the availability of soil Porg are related to microbial abundance and activity. The interactions of cover cropping and tillage indicate also that P benefit can be optimized by management decisions. Finally, these new insights into soil phosphorus cycling in agroecosystems have the potential to support further development of more sustainable agricultural systems. Phosphor (P) ist einer der wichtigsten limitierenden Naehrstoffe fuer das Pflanzenwachstum in der Landwirtschaft. Bodenmikroben spielen eine Schluesselrolle in Naehrstoffkreislaeufen, beeinflussen das Wachstum von Pflanzenwurzeln, die Mobilisierung sowie die Mineralisierung von organischem P (Porg) und somit den Zugang zu P. Das Ziel dieser Dissertation war die Einschaetzung des Potentials von Zwischenfruechten zur Verbesserung der Interaktionen im System Pflanze-Boden-Mikroben und einer dadurch moeglichen Steigerung der P-Verfuegbarkeit fuer die Hauptfruechte.  Diese Dissertation umfasst drei wissenschaftliche Veroeffentlichungen: Eine Literaturrecherche und Meta-Analyse sowie zwei selbst durchgefuehrte Feldexperimente. Die verwendeten Methoden zeigten, dass Zwischenfruechte den P-Gehalt in der mikrobiellen Biomasse, die Aktivitaet von Phosphatasen und mikrobielle Fettsaeuremarker (PLFAs) erhoehen, was auf ein gesteigertes Umsatzpotential von organischen Phosphorverbindungen hindeutet. Die Abundanz von grampositiven und gramnegativen Bakterien, sowie in geringerem Umfang auch von arbuskulaeren Mykorrhizapilzen, wurde durch Zwischenfruechte erhoeht. Gleichwohl waren saprotrophe Bodenpilze die mikrobielle Gruppe, die am meisten von der Substratzufuhr der Wurzeln und Streu profitieren konnte. Stabiles P wurde in den aktiven Bodenzonen der Rhizosphaere und Detritusphaere in labilere Porg-Pools transformiert. Bewirtschaftungseffekte, wie die Wahl der Zwischenfrucht oder Bodenbearbeitung, waren erkennbar, aber wesentlich schwaecher ausgepraegt als der Zwischenfruchteffekt insgesamt.  Unsere Ergebnisse bestaetigen, dass Zwischenfruchtanbau zur Steigerung der P - Verfuegbarkeit fuer die Hauptfrucht fuehren kann. Darueber hinaus konnten wir fuer den P- Vorteil drei grundsaetzliche Wirkungspfade aufzeigen, die in aktiven Bodenraeumen stattfinden. UEber den Wirkungspfad \u0084Pflanzenbiomasse\u0093 wird P aus dem Boden in die Biomasse der Zwischenfrucht aufgenommen und waehrend der Zersetzung der Streu fuer die Hauptfrucht verfuegbar. UEber den Wirkungspfad \u0084mikrobielle Verstaerkung\u0093 steigert die Zwischenfrucht im Wurzelraum die Biomasse und Aktivitaet der mikrobiellen Gemeinschaft, wodurch diese die Verfuegbarkeit von Porg erhoehen kann. Durch den Wirkungspfad \u0084biochemische Modifikation\u0093 scheinen manche Zwischenfruchtarten in der Lage zu sein, ueber Wurzelexsudate die P-Sorption im Boden zu senken und dadurch den Anteil an pflanzenverfuegbarem Phosphat zu erhoehen.  Weiterhin ermoeglichen die erhobenen Daten die Diskussion, inwiefern mikrobielle Funktionen und die Mineralisierbarkeit von Porg zusammenhaengen und wie die Interaktionen von Pflanzen beeinflusst werden. Zwischenfruechte steigerten sowohl die Abundanz und Aktivitaet von Mikroben, als auch die Menge an P in der mikrobiellen Biomasse. Diese Potentialsteigerung des P-Kreislaufs steigerte die Verfuegbarkeit des Porg fuer zugefuegte Enzyme. Es muss bedacht werden, dass die Rueckkopplungen zwischen Enzymaktivitaet und verschiedenen Porg-Pools komplex sind. Diese haengen von den lokalen Eigenschaften des Bodens, wie etwa der Zusammensetzung des P-Vorrats, ab und sollten durch zukuenftige Studien geklaert werden.  Drittens zeigen unsere Untersuchungen, wie die Wahl der Zwischenfrucht und die der Bewirtschaftung (z.B. Bodenbearbeitung oder Fruchtfolge) die relative Gewichtung der verschiedenen Pfade des P-Vorteils fuer die Hauptfrucht beeinflussen. Standortangepasste Zwischenfruchtsysteme erlauben es Landwirt:innen, die Funktionen ihres Agrooekosystems hinsichtlich der lokalen Bedingungen zu optimieren.  Zusammenfassend bestaetigen unsere Ergebnisse, dass der P-Bedarf der Hauptfrucht ueber die Biomasse der Zwischenfrucht gedeckt werden kann und zeigen auf, dass die charakterisierten drei Pfade des P-Vorteils durch Zwischenfruchtanbau parallel stattfinden.
