Pellets for planting timber seeds - incorporate seeds surrounded by composted organic material, bark, slurry and other additives

摘要

The topsoil in the planting area is not preworked mechanically, and small heaps of pellets are set out mechanically and automatically in quadratic formations with approximately 1.25 to 2 m intervening space. In the successively heaps, pine tree seeds with fore and/or spruce content alternate with pellets contg. deciduous tree seeds, in the successive heaps. The actual pellets contain 40 - 75 wt.% controlled, composted organic material and other biological material, 25 - 70 wt.% bark, 0 - 10 wt.% slurry, and possibly other additives, together with the seeds. Once laid in heaps on the soil, the pellets swell and form a moisture-retaining and protective cushion, thus promoting the seed growth. They also contain 1 per cent nutrient selected from nitrogen, phosphorus, potassium and/or calcium for mixt. with specific soil characteristics.
