Nutrient leaching from conventional tillage, no-till and permanent grass, R0-8419
- Local identifier
- R0-8419
- Years operational
- 1993—
- Objective
- Focus on different soil management systems.
- Description
- Between 2008 and 2018, reduced tillage was compared with moldboard ploughing, with three replicates of each treatment. In 2019, the reduced tillage treatment was changed to no-till treatment, both with the same cereal based crop rotation with cover crops. Management practices are considered together with a local farmer with interest in and experience of no-till systems and conservation agriculture. Since the experiment has large plots (40*100m), individual treatment timing can be adapted for the two systems, which is very valuable for this type of experiment. Plot 7 has been under permanent grass since the start in 1993. The grass is cut once a season and the biomass determined. This type of areas, representing land use change from arable land to set-aside land, are very interesting for producing reference values for what is reachable targets for water quality. 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 analysed for Tot-N, Tot-P, PO4-P, turbidity and K. Staff at Lanna Research Station, SLU, perform the experimental work.
