The commercialization of labour markets: Evidence from wage inequality in the Middle Ages

The Economic History Review, EarlyView.
Abstract This paper moves beyond the focus on ‘average’ wage trends in pre‐industrial economies by examining the broad diversity of pay rates and forms of remuneration across occupations and regions in medieval England. We find that whilst some workers enjoyed substantial growth in wage rates after the Black Death, there was a large group who ...

Responses of waterhemp and horseweed to cereal rye cover crop termination timing in soybean

Agrosystems, Geosciences & Environment
Field experiments were conducted in soybeans (Glycine max L.) to determine the effects of a cereal rye (Secale cereale L.) cover crop (CC), two CC termination timings (TTs), and four herbicide programs (HP) on the emergence, biomass, and seed production ...

Adapting an agroecosystem model to account for cover crop management in the Midwest USA

Smart Agricultural Technology
Agroecosystem modeling tools can provide insights into cover crop performance under varying environmental and management combinations. This study aims to (1) simulate winter cereal rye cover crops in Agro-IBIS, a process-based terrestrial ecosystem model

Phosphorus Improves Leaf Nutrient Concentrations in Wheat, Oat, and Cereal Rye

Agrosystems, Geosciences & Environment, 2019
Core Ideas Increased P availability increases leaf P and Mg in wheat, oat, and rye. The grass tetany ratio is improved with greater P availability in these species. Unlike cereal rye and oat, wheat increases shoot growth with high P levels. Winter annual

The influence of long-term inputs of catch crops and cereal straw on yield, protein composition and technological quality of a spring and a winter wheat [PDF]

, 2011
Under conditions of restricted nitrogen (N) input such as in organic farming systems, crop N uptake must rely on N mineralised from applied animal manure, crop residues and native soil organic matter.

European S2k guidelines on management of autoimmune blistering diseases in children and adolescents

Journal of the European Academy of Dermatology and Venereology, EarlyView.
Autoimmune blistering disorders (AIBDs) in children are rare, challenging to diagnose and treat and often require immunosuppressants. Until now, no paediatric care guidelines existed. The EADV Task Force for AIBDs has developed the consensus‐based recommendations, enabling physicians to adopt a uniform, tailored treatment strategy to improve outcomes ...

New criteria for the molecular identification of cereal grains associated with archaeological artefacts

Scientific Reports, 2017
The domestication and transmission of cereals is one of the most fundamental components of early farming, but direct evidence of their use in early culinary practices and economies has remained frustratingly elusive.

Integrated Palmer Amaranth Management in Glufosinate-Resistant Cotton: II. Primary, Secondary and Conservation Tillage

Agronomy, 2013
A three year field experiment was conducted to evaluate the role of soil inversion, cover crops and spring tillage methods for Palmer amaranth between-row (BR) and within-row (WR) management in glufosinate-resistant cotton.

Evidence of slowing yield growth – the example of Swiss cereal yields [PDF]

We analyze trends in yield growth and yield variability of barley, maize, oats, rye triticale and wheat in Switzerland from 1961 to 2006. In contrast to linear trends in cereal yield growth that are usually assumed for Europe, cereal yields have leveled ...
