The seed-associated microbiome has a strong influence on plant ecology, fitness, and productivity. Plant microbiota could be exploited for more responsible crop management in sustainable agriculture. However, the relationships between seed hosts related to changes from ancestor species breeded crops still remain poor understood. Our aims were i) understand effect of cereal domestication endophytes terms diversity, structure co-occurrence, by comparing four respective species; ii) test...
Soil organic matter (SOM) is indispensable for soil health and, in the context of climate change, considered a significant CO2 sink. Improving agricultural management to increase long-term carbon (SOC) stocks mitigating change requires tools that estimate short and long-cycling SOM pools. In this study, we analyzed changes fast-cycling particulate (POM) slow-cycling mineral-associated (MAOM) induced by common practices, i.e., fertilization crop rotation topsoils from 25 Central European...
Most of the available research studies have focused on production high grain yields wheat and neglected yield stability. However, stability is a relevant factor in agronomic practice and, therefore, focus this comprehensive survey. The aim was to first describe importance as well currently used practical management strategies that ensure secondly, obtain potential areas supporting complex system agronomy. target groups were German farmers with experience advisors expertise field cultivation...
Summary Arable subsoils store large amounts of phosphorus (P); however, it is unclear to what extent, and under which conditions, subsoil resources might supplement crop P acquisition. Here, we hypothesized that (i) insufficient supply in topsoil promotes acquisition from (ii) cycling regulated by nitrogen (N) supply. We sampled two German long‐term fertilizer trials Thyrow (sandy soil) Gießen (loamy‐clayey 100‐cm depth. Treatments received either NPK, NK or PK for > 60 years. assessed...
Abstract In total, 42 accessions of Origanum vulgare L., mostly originating from Europe, were evaluated, to detect molecular, quantitative morphological, and chemotype polymorphisms discover possible correlations between them. Twelve traits related morphological characteristics measured. The components in the essential oils identified by GC/MS analysis, oil contents 18 major compounds determined. A total 477 molecular including 214 AFLP (amplified fragment length polymorphism) 263 SAMPL...
The objective of this study is to understand which requirements for cereal cultivars—with regard climate change adaptation—are in demand by farmers and advisors, clarify whether there are any differences their assessments. A comparative survey was used collect data from 410 114 advisors Germany. majority both reported perceivable effects climatic on plant production. increase droughts hot spells, the increased incidence torrential rain, mild winters were mentioned as main change. For...
Abstract Background and aims : Phosphorus (P) is an essential element for crop growth. However, while links of P turnover in soils to carbon (C) nitrogen (N) availability have been described, it remains be clarified how combinations fertilizer C N additions affect stocks cycling distinct fractions at different soil depths. The objectives our study were (1) assess total are affected by organic amendments fertilization, (2) evaluate respond (3) verify whether fertilization increases biological...
Abstract Nitrogen (N) is an important plant nutrient and crucial for the growth grain yield formation of field crops such as wheat ( Triticum aestivum L. ssp. ). However, little known about influence N on secondary metabolites in grains which are supposed to be beneficial human health due their antioxidant potentials. Therefore, we investigated fertilization performance winter wheat, well total phenolic concentration, capacity, accumulation (in)soluble acids during grain‐filling phase. It...
Abstract The development of resilient cropping systems with high yield stability is becoming increasingly important due to future climatic and agronomic challenges. Consequently, it essential compare the effects different management practices, such as sequences nutrient supply, on crop yields. Long-term experiments are a valuable resource for investigating these effects, they provide enough time accurately estimate parameters. objective current study was sequencing (#1: continuous v....
Abstract Rapeseed oil is one of the most important vegetable oils in Germany. It has a favorable fatty acid composition but also contains certain amount erucic (EA). As result toxicological considerations regarding this acid, European Food Safety Authority (EFSA) established tolerable daily intake (TDI) for EA 7 mg/kg body weight 2016. On basis, maximum levels allowed Union have been reduced shortly from 50 to 20 g/kg, and infant formula follow‐on 10 4 g/kg. However, rapeseed recommended...
