Improved soil preparation

Harrowing and mounding are the most commonly used methods of soil preparation in Sweden. A relatively new method is inverted soil preparation. It consists of digging up a turf, turning it over and placing back into the pit. The result is a planting spot with nutrient-rich humus under a layer of mineral soil that creates good conditions for the plant establishment. A nationwide study shows a positive effect on the survival, growth and decrease of pine weevil damages when inverted soil preparation was used.
