skeletal soil वाक्य

Consequently, the thin skeletal soil is covered in wind-blown maritime heath made up principally of western gorse ( " Ulex gallii " ), bell heather ( " Erica cinerea " ) and heather ( " Calluna vulgaris " ).
Where a skeletal soil layer has developed on the quarry floor and spoil heaps, patches of grassland occur, with species characteristic of base-rich soils, such as quaking grass, " Briza media ", and limestone bedstraw, " Galium sterneri ".
