Soil Inoculation steers restoration of terrestrial ecosystems
Nature plants, 2016Co-Authors: E. R. Jasper Wubs, Wim H. Van Der Putten, Machiel Bosch, Martijn T BezemerAbstract:Intensive agricultural activity can degrade ecosystems, and restoration takes decades. This field study shows that Soil inocula promote ecosystem restoration, and different inocula (such as grassland/heathland) can steer restoration towards different targets.

Soil Inoculation method determines the strength of plant Soil interactions
Soil Biology & Biochemistry, 2012Co-Authors: Tess F J Van De Voorde, Wim H. Van Der Putten, Martijn T BezemerAbstract:Abstract There is increasing evidence that interactions between plants and biotic components of the Soil influence plant productivity and plant community composition. Many plant–Soil feedback experiments start from inoculating relatively small amounts of natural Soil to sterilized bulk Soil. These Soil inocula may include a variety of size classes of Soil biota, each having a different role in the observed Soil feedback effects. In order to examine what may be the effect of various size classes of Soil biota we compared Inoculation with natural field Soil sieved through a 1 mm mesh, a Soil suspension also sieved through a 1 mm mesh, and a microbial suspension sieved through a 20 μm mesh. We tested these effects for different populations of the same plant species and for different Soil origins. Plant biomass was greatest in pots inoculated with the microbial suspension and smallest in pots inoculated with sieved Soil, both in the first and second growth phase, and there was no significant population or Soil origin effect. Plant-feeding nematodes were almost exclusively found in the sieved Soil treatment. We show that processing the Soil to obtain a microbial suspension reduces the strength of the Soil effect in both the first and second growth phase. We also show that the results obtained with inoculating sieved Soil and with a Soil suspension are not comparable. In conclusion, when designing plant–Soil feedback experiments, it is crucial to consider that Soil inoculum preparation can strongly influence the observed Soil effect.

Soil Inoculation Alters Leaf Metabolic Profiles in Genetically Identical Plants
Journal of Chemical Ecology, 2020Co-Authors: Martine Huberty, Beverly Martis, Jorian Kampen, Young Hae Choi, Klaas Vrieling, Peter G. L. Klinkhamer, T. Martijn BezemerAbstract:Abiotic and biotic properties of Soil can influence growth and chemical composition of plants. Although it is well-known that Soil microbial composition can vary greatly spatially, how this variation affects plant chemical composition is poorly understood. We grew genetically identical Jacobaea vulgaris in sterilized Soil inoculated with live Soil collected from four natural grasslands and in 100% sterilized Soil. Within each grassland we sampled eight plots, totalling 32 different inocula. Two samples per plot were collected, leading to three levels of spatial variation: within plot, between and within grasslands. The leaf metabolome was analysed with ^1H Nuclear magnetic resonance spectroscopy (NMR) to investigate if Inoculation altered the metabolome of plants and how this varied between and within grasslands. Inoculation led to changes in metabolomics profiles of J. vulgaris in two out of four sites. Plants grown in sterilized and inoculated Soils differed in concentrations of malic acid, tyrosine, trehalose and two pyrrolizidine alkaloids (PA). Metabolomes of plants grown in inoculated Soils from different sites varied in glucose, malic acid, trehalose, tyrosine and in one PA. The metabolome of plants grown in Soils with inocula from the same site was more similar than with inocula from distant sites. We show that Soil influences leaf metabolomes. Performance of aboveground insects often depends on chemical composition of plants. Hence our results imply that Soil microbial communities, via affecting aboveground plant metabolomes, can impact aboveground plant-insect food chains but that it is difficult to make general predictions due to spatial variation in Soil microbiomes.

Soil Inoculation steers restoration of terrestrial ecosystems
Nature Plants, 2016Co-Authors: E. R. Jasper Wubs, Wim H. Van Der Putten, Machiel Bosch, T. Martijn BezemerAbstract:Intensive agricultural activity can degrade ecosystems, and restoration takes decades. This field study shows that Soil inocula promote ecosystem restoration, and different inocula (such as grassland/heathland) can steer restoration towards different targets. Many natural ecosystems have been degraded because of human activities^ 1 , 2 and need to be restored so that biodiversity is protected. However, restoration can take decades and restoration activities are often unsuccessful^ 3 because of abiotic constraints (for example, eutrophication, acidification) and unfavourable biotic conditions (for example, competition or adverse Soil community composition). A key question is what manageable factors prevent transition from degraded to restored ecosystems and what interventions are required for successful restoration^ 2 , 4 . Experiments have shown that the Soil community is an important driver of plant community development^ 5 – 8 , suggesting that manipulation of the Soil community is key to successful restoration of terrestrial ecosystems^ 3 , 9 . Here we examine a large-scale, six-year-old field experiment on ex-arable land and show that application of Soil inocula not only promotes ecosystem restoration, but that different origins of Soil inocula can steer the plant community development towards different target communities, varying from grassland to heathland vegetation. The impact of Soil Inoculation on plant and Soil community composition was most pronounced when the topSoil layer was removed, whereas effects were less strong, but still significant, when the Soil inocula were introduced into intact topSoil. Therefore, Soil Inoculation is a powerful tool to both restore disturbed terrestrial ecosystems and steer plant community development.
