Abstract. The formation of carboxylic acids and dimer esters from α-pinene oxidation was investigated in a smog chamber ambient aerosol samples collected during the Biosphere Effects on Aerosols Photochemistry Experiment (BEARPEX). Chamber experiments ozonolysis dry air at low NOx concentrations demonstrated two esters, pinyl-diaterpenyl (MW 358) pinonyl-pinyl ester 368), under both low- high-temperature conditions. Concentration levels were lower than assumed first-generation products...
Species choice and richness in intensively managed grassland mixtures regulate soil carbon (C) input via rhizodeposition, with potential consequences for long-term organic storage. Based on a field trial different grass-legume-forb mixtures, we removed roots from the soil, which was then subjected to particle-size fractionation trace fresh (net C rhizodeposition) into particulate matter (POM) mineral-associated (MAOM). We related these fractions root traits. Using multiple-pulse...
Abstract Comprehensive climate change mitigation necessitates soil carbon (C) storage in cultivated terrestrial ecosystems. Deep-rooted perennial crops may help to turn agricultural soils into efficient C sinks, especially deeper layers. Here, we compared allocation and potential stabilization 150 cm depth from two functionally distinct deep-rooted perennials, i.e., lucerne ( Medicago sativa L.) intermediate wheatgrass (kernza; Thinopyrum intermedium ), representing legume non-legume crops,...
Productive perennial grassland systems can increase soil carbon (C) storage compared to annual cropping systems, but the effect of species mixture composition as a means optimize C input and stabilization aboveground biomass yield at low nitrogen (N) fertilizer inputs remains unexplored.In field experiment, we measured in 2-species mixtures with grasses or forbs combined red white clover, multi-species 6 18 including all 3 plant functional groups (grass, forb, legumes). All were fertilized...
Grain legumes (GLs) are essential for sustainable agriculture, offering nutritional, agronomic, and ecological benefits. GLs predominantly grown to full maturity animal feed in Denmark across Europe. However, the EAT–Lancet Commission on healthy diets has underscored necessity of a global dietary shift towards greater direct human consumption plant protein improve health promote planetary performance. The cultivation remains limited Europe, challenged by facts like climatic...
The rising global demand for high-quality, plant-based food highlights the potential of grain legumes as protein-rich alternatives that offer environmental, climate, and health benefits. Local cultivation can enhance agricultural sustainability in Europe by diversifying cropping systems reducing reliance on synthetic nitrogen (N) fertilizers through biological N fixation. This is particularly beneficial organic systems. However, legume remains limited Northern due to short growing season,...
Contaminants taken up by living organisms in the environment as a result of anthropogenic contamination can reduce tolerance natural stressors, e.g., low temperatures, but physiological mechanisms behind these interactions effects are poorly understood. The to temperatures that cannot regulate their body temperature (ectotherms) depends on ability increase fluidity cellular membranes at temperatures. Our study shows contaminants accumulating lipids alter physical state simply being present....
Summary The contribution of large molecular size organic nitrogen (N) to plant N uptake is unclear. Soils with and without maize, at three pH levels, were treated (carbon‐14 ‐13 ( 14 C, 13 C), 15 N) triple‐labelled > 100 kD a N. After 48 h, soil maize sampled for bulk compound specific isotope analysis study the turnover in C uptake. Mineralization increased higher only maize. disappeared rapidly soils but surprisingly more derived amino acids remained than – most likely microbial...
Abstract The cycling of especially large size organic nitrogen (N) from plants into stable microbial derived soil carbon (C) and N pools is understudied, in spite composing 90% the intimate link between C stabilization. We investigated fate peptide-size protein-size fractions soils two long-term field experiments markedly differing conditions for microorganisms. combined amino acid isotope probing (AA-SIP) fingerprinting with PLFA-SIP to trace biomass. Contrary present paradigm, we found...
Due to global warming it is predicted that freeze-thaw cycles will increase in Arctic and cold temperate regions. The effects of this variation becomes particular ecological importance freeze-tolerant species when combined with chemical pollutants. We compared the effect control temperature (2 °C), daily -4 °C) constant freezing (-2 temperatures on cold-tolerance oligochaete worms (Enchytraeus albidus) tested how survival was influenced by pre-exposure 4-nonylphenol (4-NP), a common nonionic...
Rationale The cycling of peptide‐ and protein‐bound amino acids (AAs) is important for studying the rate‐limiting steps in soil nitrogen (N) turnover. A strong tool stable C N isotopes used combination with compound‐specific isotope analysis (CSIA), where a prerequisite appropriate methods peptide protein hydrolysis derivatization AAs by gas chromatography (GC). Methods We examined efficiency standard acidic (6 M HCl, 20 h at 110°C) fast 70 min 150°C) on recovery from (bovine serum albumin)....

A greener agricultural sector calls for a diet shift from meat to plant protein sources. The inclusion of grain legumes (GLs) such as faba bean (Vicia faba) and pea (Pisum sativum), further cover crops in crop rotations likely helps the transition towards more sustainable food systems, example Denmark where only 3.6% organic land cultivated with GLs. Thus, most GLs human consumption are imported dry grains small local production green peas. Yet, early harvested may offer environmental...
Abstract Background Soil organic matter (SOM) formed under legume‐based grasslands may serve as an important source of nitrogen (N) for subsequent maize growth. Aim We aimed at studying effects fertilizer type (organic and mineral N phosphorus (P) fertilizers) on release from recently SOM utilization by plants. Methods The (meat bone meal) P fertilization turnover were examined ( Zea mays L.) a sand loamy typic hapludult in outdoor pot experiment over 55 days. plant uptake derived was...
