This dataset represents the harrowing operation in one hectare (ha). This tillage operation is mainly performed to break up the surface of the soil and to incorporate the limestone and gypsum. Functional Unit (FU) is one hectare of tillage harrowing. The operation time is about 1.38 hours per ha (62.5% of this time is effectively worked, discounting time for maintenance, waiting in the field and re-allocations between the plots).
Undefined unit processes (UPRs) are the unlinked, multi-product activity datasets that form the basis for all of the system models available in the ecoinvent database. This is the way the datasets are obtained and entered into the database by the data providers. These activity datasets are useful for investigating the environmental impacts of a specific activity (gate-to-gate), without regard to its upstream or downstream impacts.
