Soil organic carbon (SOC) content is the most widely used soil health indicator, but many functions are also influenced by quality of SOC. Yet, standardized SOC parameters that can be in assessments addition to still development. Here, we investigated relationships between various (both quantity and quality) functions. We collected 223 samples from arable fields two contrasting Dutch types i.e., marine clay sand. For each sample, assessed three (i.e., biological population regulation,...
It is generally assumed that the dependence of conventional agriculture on artificial fertilizers and pesticides strongly impacts environment, while organic relying more microbial functioning may mitigate these impacts. However, it not well known how diversity community composition change in conventionally managed farmers' fields are converted to management. Here, we sequenced bacterial fungal communities 34 sand marine clay soils a time series (chronosequence) covering 25 years conversion....
There is an increasing interest in developing agricultural management practices that support a more nature-based, sustainable food production system. In organic systems, extracellular enzymes released by soil microorganisms are important regulators of the cycling and bioavailability plant nutrients due to lack synthetical inputs. We used chronosequence coupled with paired field approach evaluate how potential activity hydrolytic changed over time (0–69 years) during transition from...
Accurate quantification of soil organic carbon (OC) pools is essential to study the dynamics OC in soils. Therefore, matter often separated into physical fractions with distinct turnover times, e.g. particulate (POM) and mineral-associated (MAOM), after which their content measured. Calcareous soils are under-represented such fractionation studies, because required analytical differentiation between inorganic (IC) not straightforward implies more processing time, sample mass equipment. Here,...
Agricultural soils in intensive farming sustain high crop production yields but endanger other regulating ecosystem services. Strengthening the simultaneous delivery of multiple soil functions is therefore essential to achieve while lowering environmental impact. We investigated how this so-called multifunctionality related management intensity conventional and organic arable farming, specific practices regarding e.g. rotation, fertilization or tillage. furthermore explored whether carbon...
Organic farming is often considered to be more sustainable than conventional farming. However, both systems comprise highly variable management practices. In this study, we show that in organic and arable fields, the multifunctionality of soils decreases with increasing agricultural intensity. Soil carbon content bacterial biomass, respectively, were strongest abiotic biotic predictors soil multifunctionality. Greater was associated less-frequent inversion tillage higher frequency...
Abstract We steered the soil microbiome via applications of organic residues (mix cover crop residues, sewage sludge + compost, and digestate compost) to enhance multiple ecosystem services in line with climate-smart agriculture. Our result highlights potential reduce greenhouse gases (GHG) emissions from agricultural soils by application specific amendments (especially compost). Unexpectedly, also addition mineral fertilizer our mesocosms led similar combined GHG than one amendments....
Organic farming aims at producing high quality, nutritious food while sustaining the health of soils and ecosystems, for which it relies on ecological processes. The amount quality soil organic carbon (SOC) influence many processes that underlie ecosystem services. However, effect especially SOC is not yet clear. We therefore investigated long-term arable in topsoil.On two contrasting types (i.e., clay vs. sand), we sampled a chronosequence certified organically managed commercial farms (0...

Monitoring agriculture by remote sensing enables large-scale evaluation of biomass production across space and time. The normalized difference vegetation index (NDVI) is used as a proxy for green biomass. Here, we satellite-derived NDVI arable farms in the Netherlands to evaluate changes following conversion from conventional organic farming. We compared stability 72 fields on sand marine clay soils. Thirty-six these had been converted into between 0 50 years ago (with 2017 reference year),...
Soil organic carbon (OC) is pivotal for soil functioning, especially in the domains of elemental cycling, disease control and regulation structure water. High OC contents are generally associated with improved therefore content widely used as a health indicator. The stability influences all functions that depend on microbial decomposition (e.g. nutrient provisioning) or retention C sequestration). Yet, standardized indicator can be assessments still development. Here, we investigate to what...
