2.3. Soil substitutes blends
Soil substitutes were prepared by appropriate blending of wastes (Table
3). The experiments were run at three operational stages, namely I, II
and III. During the study four types of soil substitutes blends with
different fertility and water retention ability were developed i.e. dry
and moderate fertility (A), mesic and low fertility (B), mesic and
moderate fertility (C), humid and low fertility (D). Soils substitutes
blends (A1-D3) differed from each other in terms of the type of wastes
and their percentage share (n=36).
