We studied trial plantations of Scots pine ( Pinus sylvestris L.), Siberian larch ( Larix sibirica Ledeb.), Norway spruce ( Picea abies L. ) and silver birch ( Betula pendula var. carelica Mercl.) growing on recultivated tailings of YPF. Our morphometric studies showed that green sands have had essential effects on primary pedogenesis and vertical differentiation of recultivated soils. We found alkalizing effect of green sands on the recultivated soils, growth of cation exchange capacity, available phosphorus and potassium at the trials. However green sands had low effect on labile nitrogen and humus contents. Dendrologic measurements in 1997, when plantations had been 10 years old, have showed successful growth of pine in all plantations, compared to Siberian larch, Norway spruce and silver birch. All plantations have had highest growth increment on sites where thickness of green sand was 30 cm. Repeated measurements in 2015 did not show significant difference of the dendrometric indicators between the plantations and control. We suggest it was caused by the distribution of root system in the soil profile. At the onset of growth it have had been in the upper mineral layer with the improver. 28 years after, the roots have passed the green sand layer and penetrated the overburden rock having low fertility. Green sands had positive effect on root-taking of tree species like Siberian larch, which degraded at the control site. Keywords: green sands, recultivation, forest plantations, Yegoryevsk phosphate field.
