The field rent includes costs and depresiations:
There is no salaries in the field rent. Therefore, all staffing for establishment, harvesting, sowing plots (requires extra hours), observations, irrigation, special treatments and other registrations in the field during the experiment.
When budgetting in applications with field experiments, it is allways a good idea to talk with the driftslederen on the location where your experiment is planned, to gain clarity on what is included and what requires extra staffing.
AGRO's occupational health and safety committee (LAMU) has been working on putting focus on safe trafic in the field after spraying.
