Deherain Plots, Long Term Cropping/Soil Experiment, France
Entry ID: INRA.Deherain

[ Update this Record ]

Summary
Abstract: The Deherain long-term field experiment was started in 1875 to study the
impact of fertilization on crop yield. Before 1875, the soil was
cultivated with alfalfa without fertilization. Between 1929 and 1986,
the plots were under a wheat-sugarbeet rotation. Since 1987, the
plots have been cultivated with maize.

The average climatic conditions at the experimental site are:
