This is what this would be called in English. The word dressing is added when the peat moss is being used on lawns and such.

Harvested from the upper portion of the bog, this slightly humified (naturally decomposed) and highly organic material contains a rich supply of nutrients that are required when used as a soil additive/amendment for flower beds, new lawns, bedding plants, potting soils, etc. With a moisture holding capacity of up to 12 times its own weight and a PH of 4.9 to 5.1, when mixed with native soils Superior Peat Moss and Peat Soil provides a soil conditioner that balances the air and moisture around the plant roots.

Top dress -- After you aerate, top dress your lawn by spreading 1/8 inch to 1/4 inch of peat moss over the grass with a rake. The top dressing of peat helps gradually condition the lawn throughout the growing season, strengthening the grass to resist disease and thatch, and reducing the amount of water and fertilizer it needs. Peat moss absorbs moisture and reduces the leaching of nutrients by holding and releasing them slowly over time.
