3.2. Effects of sludge applications on larch seedlings
3.2.1. Seedling survival and growth parameters
One year after the SS application, L. decidua exhibited a higher
survival rate (98.3%). The stem height growth of the L. decidua
seedlings receiving SS increased significantly compared to the
control seedlings (Fig. 2). This increase appeared for both
treatment rates after 7 months of culturing; however, between
seedlings having received the 30S treatment as opposed to the 60S,
no differences were found. Significant increases in biomass
accumulation were observed in both the aerial and root parts
compared to the control (Fig. 3).
