From Pioneer to Soil Prophet: 40 years belowground - Farewell symposium Wietse de Boer
On Thursday April 4 we'll have the Farewell Symposium and reception for our long-time colleague Prof. Dr Wietse de Boer (Department of Microbial Ecology at NIOO and Wageningen University). -
Impact of nutrients
Nutrient availability in natural ecosystems has increased due to anthropogenic activities like spill-over from agricultural ecosystems. In the Netherlands, this has led to the acidification of natural areas for example. At NIOO, we aim to understand the impact of nutrients on natural systems in more detail, to help to bring back the balance. -
Greenhouse gases
Climate change is amplified by greenhouse gas emissions. At NIOO, we work on the fundamental understanding of how gases such as methane, carbon dioxide and nitrogen dioxide influence ecosystems. Our knowledge of carbon and nitrogen cycles provides insight into the potential of greenhouse mitigation tools. In a Dutch freshwater lake or the soil of a tropical rain forest. -
Enhancing Soil Biodiversity
At NIOO, we are on a mission to explore the strange world beneath our feet, to seek out new soil-borne life, uncover new miniature civilisations, and to boldly take humankind where it could not go before. -
Soil biodiversity analysis for sustainable production systems (SoilProS)
SoilProS will interpret big data on soil biodiversity, soil chemical and physical characteristics with respect to current and desired soil functions, and how to use this information in order to help farmers predicting which crop varieties, seed mixtures, (organic) fertilizers, soil inocula, and organic substrates enhance the environmental sustainability of their activities. -
Spotlight on living soil at COP15 biodiversity conference
The UN Biodiversity Conference in Montreal (COP15) is discussing global action to reverse biodiversity loss. Healthy, living soil is of key importance. -
Microbial Networks controlling soil greenhouse gases emissions
Soils are considered principally non-renewable resources. Soil ecosystem services have a large impact on numerous societal demands and are of high economic importance. Within the area of sustainable agriculture, it is expected that agricultural production will increasingly rely on the natural nutrient retention and recycling capabilities of soil. This project seeks to provide a fundamental scientific understanding of soil functioning and the resulting ecosystem services in Brazilian and Dutch bio-economies based on innovative microbial ecology and soil science studies. Focus is in sugarcane crop production systems by linking soil microbial composition and functioning, waste residues recycling, fertilizers, soil factors and greenhouse gases (GHG) emissions through integrating and complementing the strong expertise of Brazilian and Dutch researchers from different areas of agronomy, soil sciences, plant nutrition, biogeochemistry, soil ecology, microbial ecology, ecological genomics, molecular ecology and bioinformatics. We will quantify the microbial functional groups and microbial abundance of C and N cycle genes and measure GHG emissions (CO2, CH4 and N2O) from soils during the productive cycle of the plant under different management practices and verify the temporal and spatial variability of these emissions in the evaluated treatments with different concentrations of sugarcane vinasse residue combined with N mineral fertilizers in combination with straw additions, and determine the conditions under which such GHG emissions can be counteracted, or minimized most. The proposed project will enhance fundamental scientific understanding of the interactive role of the microbial networks operating in soil and the consequences of bio-based agricultural management practices for the functioning of soil systems. -
Farming microbial community for plant probiotic - MicroProFarm
A current challenge for modern agriculture is to meet the food production needs for an increasing global population while improving resource use efficiency and attenuating impacts on human health and environment. In order to maximize reliability and stability in agriculture, optimization of crop management and resource use efficiency have been considered the best approaches for a sustainable increase of crop yields under variable agro-ecological conditions, environments and years. For this purpose, one interesting and sustainable method is the use of natural plant biostimulants, a diverse class of products and microorganisms that enhance plant growth and other plant parameters, such as flowering, fruit set, crop productivity and nutrient use efficiency. In this context, several studies already demonstrated that plant biostimulants can induce morpho-anatomical, biochemical, physiological and molecular plant responses, not only improving crop productivity but also promoting protection against abiotic stresses, such as drought and salinity. Among the different biostimulant classes there are protein hydrolysates (PH), mixtures of polypeptides, oligopeptides and aminoacids originated from partially hydrolyzed animal and vegetal tissues. Even though the effect of PH were already observed in diverse crops, the mechanisms and behind their action are still scarcely studied, and their action can vary depending on their origin, characteristics, crop species, cultivars, growing conditions, time and mode of applications, among other parameters. The objective of this project is to evaluate the effect of protein hydrolysates in the growth, nutrient content and microbial communities of crops, if microbes are responsible for these effects, which are the mechanisms and if such effects are long-lasting. -
Sustainable use of land & water
Healthy surface water and soils are essential for life on earth, providing diverse life-support functions. How are these ecosystem services affected by human activity, and how can we change this?
