Fertilisers in the Long 19th Century and Beyond: Usage, Commercialisation and Production (c 1800–1939).

The introduction to the volume provides an overview of processes in the industrialization of agriculture in the 19^th and 20^th centuries with regard to fertilisation. It explains the interplay between the intensification of fertiliser usage and agricultural output which enabled immense population growth. It shows how chemical discoveries surrounding nitrogen, potassium and phosphorus (NPK) eventually led to a diversification of markets and the formation of big fertiliser businesses. Indeed, every specific fertiliser chain was linked to a wide set of markets and institutions, as to stakeholders with various and potentially conflicting interests. This issue aims to shed light on this aspect within several regions across Europe and beyond. [ABSTRACT FROM AUTHOR]
