History
Conventional intensive tillage with mouldboard plowing and winter cereal monoculture.
Management
Barley is planted in November by disk direct drilling. After harvest, the straw residue was chopped and spread over the soil.

tillage process
no-till
Glyphosate applied for weed control before sowing.
conventional tillage  (25 cm depth)
Application method: mouldboard plough
Mouldboard plow to 25 cm depth followed by two passes of a cultivator to 15 cm depth, both in September–October
nitrogen fertilizer exposure
Nitrogen applications were split with one-third applied before seeding as ammonium sulphate (21% N) and the remainder at the beginning of tillering, in February, as ammonium nitrate (33.5% N).
