For a first time the atlas maps the soil biodiversity of the entire planet, and provide s comprehensive analysis of human-induced threats to soil organisms and soil functioning, facilitating development of new policies to protect soil and soil organisms.

Soil is a home for an unbelievable diversity and abundance of microbial life that is essential for supporting life on our planet.

How soil microbial composition impacts structure and composition of the aboveground plant and animal communities?

We will study how inoculation of former arable land with soil (including the microbiome, soil fauna and seeds/rhizomes of ground flora) from old forests along with planting targeted tree species mixtures will improve productivity and more rapidly restore forest-adapted communities and ulttimately result…

In this thesis, the role of plant-mediated soil legacy effects in shaping aboveground plant-insect interactions was investigated.

Soil biodiversity is of great importance for the maintenance of multifunctionality in terrestrial ecosystems.

The soil ecosystem consists of the largest reservoir of biodiversity on Earth.

The main research question of this thesis was: Can nitrogen cycling on dairy farms on peat soil in the Dutch Green Heart area be improved by adapting management to the nitrogen supply from soil and by using other grassland species and crops without affecting milk production?

By growing in a soil plants change the biotic and abiotic properties of the soil in which they grow.

Plants and soils from natural ecosystems harbor great diversity of soil microorganisms, which could potentially contribute to the sustainability of horticulture. The knowledge about using wild plant species and soil from natural ecosystem to improve the crop health will advance the application of ecological…

We examine how soil-derived legacy effects of plants structure natural ecosystems, determine aboveground plant insect interactions, and how we can use soil legacy effects to restore degraded ecosystems.

In this thesis, I focused on studying the above- and belowground interactions of J. vulgaris from a plant-soil feedback (hereafter, PSF) perspective. I investigated the temporal variation of negative PSF and examined the effects of root-associated bacteria on plant performance and aboveground herbiv…

Archaeobotanic research by prof. dr. C. Bakels and students on agriculture.

In this PhD study, I aim to deepen our understanding of the influence of major mycorrhizal types, namely arbuscular mycorrhizae (AM) and ectomycorrhizae (EM), on the global soil carbon cycle and their potential distribution changes under future environmental shifts.

The use of N fertilizers has increased worldwide in the past century. While this increased input of N has increased food productivity, it has also contributed to decreases in biodiversity, soil quality and environmental health, including increases in greenhouse gas emissions.

Which compounds and microorganisms that live near and inside plant roots are beneficial? Can we use this knowledge to improve the health and growth of crop plants?

We examine how soil inoculation influences aboveground organisms (i) directly, and indirectly via (ii) its effects on plant chemistry or volatile emission, or via (iii) mediating the effects of belowground pathogens on aboveground organisms via the shared plant.

Vinasse is a major by-product generated by the sugarcane biofuel industry. It is a source of microbes, nutrients and organic matter and often it is recycled as fertilizer.

Striga hermonthica, commonly known as witchweed, infests major cereal crops in Sub-Saharan Africa causing severe yield losses and threatening the livelihood of millions of resource poor farmers.

CML researchers has contributed to development of the first-ever Global Soil Biodiversity Atlas , which has been published recently by the European Joint Research Centre (EU JRC) and the Global Soil Biodiversity Initiative (GSBI).

The Spanish Society of Soil Science has chosen as the best thesis of 2015 (call 2016) in Spain to the CML-researcher Daniel Arenas Lago, for his research at the University of Vigo that expands and deepens in new knowledge about adsorption and retention of heavy metals in soils, an issue increasingly…

Soil bacteria can produce a wealth of antibiotics that are new to us, claims Gilles van Wezel, Professor of Molecular Biotechnology at the Institute of Biology Leiden. His research group has developed a method that can rapidly identify and produce these unknown compounds.

From 11-13 September 2017 the 34th Pontignano Seminar took place at the location where it originally started: the Pontignano Cloister, nearby Siena in Italy.

Music from a compostable cello, photographs and scents of fungi and a woven tapestry. With her upcoming multimedia project Super Organism, visual artist Suzette Bousema enables people to experience the underground fungal network with all their senses.

Beryl ter Haar is currently a Visiting Professor at the University of Warsaw, Poland. The Law School is the oldest part of the university (founded in 1808), followed by the School of Medicine (founded one year later). The two schools became the heart of Warsaw University which was founded in 1816 by…

From 23-26 September 2019, Beryl ter Haar, assistant professor Labour Law, delivered the national report on 'cross border labour law in the Netherlands' at the at the XXXVI Pontignano Seminar with the theme: Worker´s mobility in the European Union: labour law perspective'.

From 25-27 June 2017 the 3rd Conference of the Labour Law Research Network took place in Toronto, Canada. Beryl ter Haar participated in two panels. The first panel dealt with strike law from a comparative perspective between South Africa, Russia, The Netherlands, and Europe. The contribution of Beryl…

In late medieval and early modern times, books, as well as the people who produced and read (or listened to) them, moved between regions, social circles, and languages with relative ease. Yet, in the multilingual Low Countries, francophone literature was both internationally mobile and firmly rooted…

How does the soil we grow our vegetables in, affects the health of our gut? And does a healthy soil gives crops a better quality and taste? These are some of the questions Soil ecologist Emilia Hannula and a big consortium will work on. With an NWO-KIC grant of 1.8 million, CML, IBL, FGGA, the LUMC,…

Leaf-eating caterpillars greatly enrich their intestinal flora by eating soil. Even effects of plants that previously grew in that soil can be found back in bacteria and fungi in caterpillars. Researchers from the Netherlands Institute of Ecology (NIOO-KNAW) and Leiden University write about this discovery…

A group of 12 LUC students went to the Eifel mountains for the annual field trip within the course 'Soils, Sediment, and Society' of Dr. Peter Houben. Dr. Peter Houben is Assistant Professor of Environmental Earth Sciences and Sustainability at Leiden University College The Hague.
