In drawing up energy balances and environmental life cycle assessments for agricultural processes or products the part resulting from the supply (manufacturing, maintenance) and disposal or recycling of the inputs considered (fertilisers, machines, etc.) often plays a non negligible role. This concerns not only the energy demand of the upstream processes needed for each one of the inputs, but also air and water emission caused by their supply (emission due to manufacturing, production of energy carriers, etc.). The report on hand presents the inventory of the most important non renewable resources and of the emission caused by the supply of the agricultural inputs most commonly used in plant production. The corresponding data concern some 40 active substances and about ten different types of fertilisers and offer basic information as regards agricultural machines and vehicles, seeds, agricultural buildings and plastic material. About 80 items of the environmental inventory are dealt with, the priorities for drawing up shortened inventories being mentioned. The calculating methods are detailed for each input, the application of the inventory is shown by an example and a short discussion presents the possibilities of assessing the published data from an energy and environmental point of view
