There was an error in the original publication [1]. A correction has been made to Abstract, 3.1. Nitrogen Content of the Vegetation Mats, paragraph 1, Table 3 and Table 7.

Abstract: The vegetation mats with sheep’s wool (V1–V3) contained 192.6, 154.0, and 283.5 g nitrogen (N)/m² and the coir mats (V4) contained 7.5 g N/m².

3.1. Nitrogen Content of the Vegetation Mats, paragraph 1: The analysis of total nitrogen showed 10.4% for the sheep’s wool fibres and 0.3% for the coconut fibres. The subsequently calculated nitrogen content in the four vegetation mat types averaged between 7.5 g of nitrogen (variant 100c) and 283.5 g of nitrogen (sandwiched variant) per m² vegetation mat (Table 3).

Table 3. Calculated nitrogen content of the fibres (air dry) of the used vegetation mats.

Mat Variant	N-Content of Sheep’s Wool Fibres in the Vegetation Mat (g/m²)	N-Content of Coconut Fibre in the Vegetation Mat (g/m²)	Total N-Content of Fibres in the Vegetation Mat (g/m²)
V1: 50sw/50c	187.2	5.4	192.6
V2: 30sw/70c	145.6	8.4	154.0
V3: Sandwich	280.8	2.7	283.5
V4: 100c	0	7.5	7.5
