“Black earth” is a kind of productive peaty ground.

Assessment of the quality of the terrain must include what ground/soil types can be found at the harvesting site.

Mires and peatlands cannot be formed in areas with mild climates along the coast.

All productive peatlands have extremely high carrying capacity.

Silvicultural activities should be conducted on bedrock surface.

The bedrock is often exposed in various places at moraine/till sites.

Silt is poor in fine particles and does not have good ability to hold and transport water.

Clay soils are found in low parts of the terrain, often adjacent to lakes.

Sites with clay-dominated soils are not easy to distinguish because they are, or have been, cultivated.

If it is possible to roll the soil into a “thin thread” it consists largely of silt or clay.
