Agronomia i agrònoms a la Reial Acadèmia de Ciències Naturals i Arts de Barcelona (1766-1808)

Aquest treball estudia l’activitat agronòmica de la Reial Acadèmia de Ciències Naturals i Arts de Barcelona durant el període que abasta des de 1766 fins a 1808. Se centra en l’anàlisi de la documentació generada per la Direcció d’Agricultura d’aquesta institució, fent èmfasi en l’estudi del perfil biogràfic i intel•lectual dels homes que hi van estar al capdavant, i en la producció científica que van arribar a dur a terme. El treball enumera i analitza les propostes tècniques per millorar l’agricultura que des d’aquesta corporació es van sotmetre a debat. En aquest sentit, es destaquen les aportacions en temes com la vinya, els nous conreus o el debat sobre la situació de la ramaderia al país.
