Abstract. The spatial assessment of soil functions requires maps basic properties. Unfortunately, these are either missing for many regions or not available at the desired resolution down to required depth. field-based generation large datasets and conventional remains costly. Meanwhile, legacy data comprehensive sets environmental regions.Digital mapping (DSM) approaches relating (responses) (covariates) face challenge building statistical models from covariates originating, example,...
In a field experiment we investigated the efficiency of two hyperaccumulating species, four agricultural crop plants, and one woody crop, at phytoextraction Zn, Cd, Cu from polluted calcareous soil. addition, examined possibility to enhance these metals by application nitrilotriacetate (NTA) elemental sulfur (S8) Metal uptake species was higher than that but generally low in all treatments compared results reported literature, maybe as result lower total available soil metal concentrations....
The application of mineral phosphate (P) fertilizers leads to an unintended Cd input into agricultural systems, which might affect soil fertility and quality crops. fluxes at three arable sites in Switzerland were determined by a detailed analysis all inputs (atmospheric deposition, P fertilizers, manure, weathering) outputs (seepage water, wheat barley harvest) during one hydrological year. most important (0.49 0.57 g ha-1 yr-1) manure (0.20 0.91 yr-1). Mass balances revealed net losses for...
For polar and more degradable pesticides, not many data on long-term persistence in soil under field conditions real application practices exist. To assess the of pesticides soil, a multiple-compound screening method (log Kow 1.7-5.5) was developed based pressurized liquid extraction, QuEChERS LC-HRMS. The applied to study 80 >90 transformation products (TPs) archived topsoil samples from Swiss Soil Monitoring Network (NABO) 1995 2008 with known pesticide patterns. results reveal large...
Analyses of stable metal isotope ratios constitute a novel tool in order to improve our understanding biogeochemical processes soil-plant systems. In this study, we used such measurements assess Cd uptake and transport wheat grown on three agricultural soils under controlled conditions. Isotope were determined the bulk C A horizons, Ca(NO3)2-extractable soil pool, roots, straw, grains. The was isotopically heavier than horizon (Δ(114/110)Cdextract-Ahorizon = 0.16 0.45‰). plants slightly...
Spatial monitoring of grassland management is crucial for ecosystem assessment and the establishment sustainable agriculture. Switzerland covered by large areas small structured parcels differing in practices use intensities, making mapping challenging. We present a tool to map management, distinguishing between mowing- grazing practice, different intensities Swiss agroecosystems. By analyzing pixelwise spectral time series 2015, derived from satellite imagery Landsat archive, we estimated...
The supplementation of Zn to farm animal feed and the excretion via manure leads an unintended input agricultural systems, which might compromise long-term soil fertility. fluxes at three grassland sites in Switzerland were determined by a detailed analysis relevant inputs (atmospheric deposition, manure, weathering) outputs (seepage water, biomass harvest) during one hydrological year. most important occurred through (1076–1857 g ha–1 yr–1) mass balances revealed net accumulations (456–1478...
The temporal evolution of soil organic carbon (SOC) is major importance given its status as a key parameter in many functions. Furthermore, soils constitute an important reservoir our environment. In light climate change, consistent SOC data over extended periods combination with information on agricultural management are much required, but still scarce. We report changes the topsoil (0–20 cm) Swiss cropland measured at well-defined monitoring sites resampled every 5 years from 1990 to 2014...
An approach to identifying persistent organic contaminants in the environment was developed and executed for Switzerland as an example of industrialized country. First, samples were screened with in-house list using liquid chromatography high-resolution mass spectrometry (LC-HRMS/MS) gas tandem (GC-MS/MS) 13 from Swiss National Soil Monitoring Network three sediment cores urban agricultural contaminated lake. To capture a broader range contaminants, analysis extended suspect screening by...
In this study a large dataset on the polycyclic aromatic hydrocarbon (PAH) content of Swiss soils was analysed to evaluate two source apportionment tools, i.e., characteristic PAH ratios/molecular markers and linear mixing model. Population density total organic carbon (TOC) were identified by multiple regression model as independently positively influencing concentrations in background soil. Specifically, TOC more strongly correlated with sum light (naphthalene phenanthrene) than heavy...
Abstract This paper describes the application of gel permeation chromatography to morphology polymer single crystals. Various types crystals polyethylene were etched with fuming nitric acid, and molecular weight distributions degraded fragments determined. The crystal preparations studied monolayer grown from xylene solution at 85°C multilayer 84°C 70°C. In all cases peaks in distribution observed corresponding double transverses chains through lamellae. By using chromatograph calibration...
Summary Remobilization of zinc (Zn) from shoot to grain contributes significantly Zn concentrations and thereby food quality. On the other hand, strong accumulation cadmium (Cd) in is detrimental for Zinc isotope ratios were measured wheat shoots ( Triticum aestivum ) at different growth stages elucidate pathways processes during filling. mass decreased while heavy isotopes accumulated straw filling (Δ 66 full maturity–flowering = 0.21–0.31‰). Three quarters moved grains, which enriched...
Abstract. Information on soils' composition and physical, chemical biological properties is paramount to elucidate agroecosystem functioning in space over time. For this purpose, we developed a national Swiss soil spectral library (SSL; n=4374) the mid-infrared (mid-IR), calibrating 16 from legacy measurements soils Biodiversity Monitoring program (BDM; n=3778; 1094 sites) long-term Soil Network (NABO; n=596; 71 sites). General models were trained with interpretable rule-based learner...
