De Koplopers: Natte natuur als klimaatbuffer
Zoals gebruikelijk oogsten de waterschapsverkiezingen in maart weinig belangstelling, maar ze bieden juist de kans om Nederland klimaatrobuust te maken. Wat staat er precies op het spel? Kan onze veranderende kijk op water voorkomen dat we van crisis naar crisis struikelen? -
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. -

'It depends': soil organic matter doesn't automatically increase crop yield
More organic matter in the soil may be beneficial for the climate, but contrary to what's been assumed it doesn't automatically increase crop yield. The amount is not the only factor, concludes research by NIOO's Stijn van Gils: it also depends on the context. -
Stof tot nadenken: niet automatisch meer oogst door meer organische stof in bodem
Dat de hoeveelheid organische stof in de bodem de vruchtbaarheid en dus de opbrengst bepaalt, blijkt toch anders te liggen. Onderzoek van het Nederlands Instituut voor Ecologie (NIOO-KNAW) wijst dat uit. Waar het voor het klimaat goed is om meer organische stof ā de C van CO2 ā in de bodem te stoppen, heeft een boer daar pas wat aan als hij verder kijkt dan hoeveelheden alleen. NIOO-onderzoeker Stijn van Gils promoveert vandaag op dit onderzoek bij Wageningen University.
