Paperback. Condizione: New. This collection features five peer-reviewed reviews on weed management in regenerative agriculture.The first chapter provides an analytical review of the adoption of Conservation Agriculture (CA) in Sub-Saharan Africa by smallholder farmers, focusing on the challenges posed by weed management. The chapter assesses chemical and non-chemical weed control methods and their benefits in CA systems.The second chapter considers the adoption of integrated weed management (IWM) in organic cropping systems, focussing on the key challenges that can arise as a result of this adoption. It also presents examples of successful integration between preventive, cultural and direct tactics in an IWM strategy.The third chapter highlights an increasing need for IWM strategies in the face of herbicide-resistant weeds, soil degradation and environmental contamination by herbicides. The chapter reviews the cultural techniques available to manage weeds in a sustainable manner.The fourth chapter introduces the concept of using crop rotations and cover crops as an effective and sustainable strategy for controlling weeds and looks ahead to future research in this area.The final chapter utilises four detailed case studies from across Europe to illustrate the effectiveness of combined methods to control weeds and preserve/improve farmers' income.

He recognized these reptiles shared a unique combination of features and established Dinosauria as a distinct subgroup of "saurian reptiles". Owen also used the fossil record to develop the concept of homologous structures and the "vertebral archetypThe journal began publication in 1817.

Très rare édition originale de ces études de minéralogie et de chimie, une grande partie de l'ouvrage concernant plus particulièrement les météorites, une des grandes passions du scientifique. Nombreuses figures dans le texte.Il a été relié avant la page de titre un demi-feuillet reprenant toutes les distinctions de l'auteur (la liste est longue !).Envoi autographe signé au verso du premier feuillet blanc : « Monsieur De Bois Baudran (sic) with the best (?) regard of J. Lawrence Smith ».John Lawrence Smith (18181883) Chimiste et minéralogiste américain. Il a publié de nombreux articles sur la chimie analytique et la minéralogie, notamment Mineralogy and Chemistry, Original Researches (1873). Sa collection de météorites était la plus belle des États-Unis, et à sa mort, il la légua à Harvard. La médaille, décernée tous les trois ans par La National Academy of Sciences pour des études sur les corps météoriques porte le nom de J. Lawrence Smith en son honneur.La dédicace est adressée à Paul-Emile Lecoq de Boisbaudran (1838-1912), chimiste français. En 1874 il publie Spectres lumineux, spectres prismatiques, et en longueurs d'onde destinés aux recherches de chimie minérale, un des ouvrages fondateurs de la spectroscopie. En 1875, à l'aide de ces méthodes, il découvre les indices d'un nouvel élément chimique. Il appelle cet élément le gallium. C'est une consécration pour la théorie de Mendeleïev qui en avait prédit les caractéristiques sous le nom d'« eka-aluminium ».
