Nutrient leaching - Strategies for cover crops in southern Sweden, R0-0701

Local identifier: R0-0701
Years operational: 1993—
Objective: Different cover crop mixtures sown after harvest in autumn.
Description: Flow proportional nutrient leaching from separately tile-drained plots, nutrients from harvest and soil sampling measuring the mineral nitrogen. The experiment R0-0701 on Lönnstorp Research station, SLU, has a focus on vegetation cover of the soil in autumn and cover crops in a southern Sweden (Skåne) context, but has no fixed set up. The treatments has changed since the start 1993 in order to follow the development of agriculture and address current crop management issues. There has been a rotation of treatments over the plots in order to avoid build-up of differences between individual plots. Biomass samples of cover crops and weeds are collected every autumn with analyses of N and C. Samples for soil mineral N is taken at harvest, late autumn and in spring. Yields of main crop are determined every year with analyses of N, P and K and samples of grain are archived. Samples for basic soil chemical properties are taken with six years interval (archived). Water flow is registered and flow-proportional water samples are analyzed for Tot-N and Tot-P. Earlier years also NO3-N, PO4-P and K was analyzed.
