Nutrient leaching from a cereal crop rotation with cover crops, autumn and spring tillage, R0-8410
- Local identifier
- R0-8410
- Years operational
- 1993—
- Objective
- Measuring how different crop management influences the leaching losses of N, P and K. The different treatments were pig manure, stubble cultivation, autumn and spring tillage, and cover crops. From 2007, the experiment has three treatments, which compares autumn tillage in October-November, with spring tillage in March-April, with and without undersown perennial ryegrass (Lolium perenne) cover crops.
- Description
- The main crops and crop management follow the management of the farm Fotegården where the experiment is located. The crop rotation is mainly spring cereals, but potatoes are grown some years. Biomass samples of cover crops and weeds is collected every autumn with analyses of N and C. Samples for soil mineral N have been taken most years at harvest, late autumn and in spring. Yields of main crop are determined and analysed for 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 analysed for Tot-N and Tot-P. Earlier years also NO3-N, PO4-P and K was analysed. Staff at Lanna Research Station, SLU, perform the experimental work.
