Growth of scots pine (Pinus sylvestris L.)and occurrence of soil mites (Acari) on the reclaimed post-military area at forest district Żołędowo

key words: post-military area, land reclamation, revitalization, Scots pine, Acari, Oribatida

Summary:

The aim of the study was the comparison of the Scots pine(Pinus sylvestris L.) growth and the state of fauna of soil Acari in 2-year cultivations on the afforested post-military area as well as on the forest soil in District Żołędowo. Two-year old Scots pine seedlings - produced in field nurseries at mulching, organic fertiliza-tion and traditional treatments applied - were used for afferestation and renova-tion. Trials were carried out in the year 2009. The experiment included the follow-ing factors (treatments): the way of preparation of the area destined for afforestation - with sowing of lupin (A) or without lupin (B). The second factor was the way of seedling production used at forest nursery: 1 - compost with addi-tion of bark, without mulching, 2 - compost with addition of bark, with mulching, 3 - compost with addition of sawdust, without mulching, 4 - compost with addi-tion of sawdust, with mulching. All the results were compared with the control area (C) which was localized on the forest soil. On the base of chosen growth in-dices comparison in two-years' old Scots pine cultivation on the reclaimed post-military area, it was found that the treatment of lubin sowing did not influence significantly on these parameters. Mulching measure - which was conducted in nursery - influenced advantageously on the shaping of all the investigated growth indices of Scots pine in two-years' old forest cultivation. Changes of the soil mites dimension and the species diversity of the oribatid mites in the successive years of the initial stage of succession indicated the revitalization processes have been oc-curring on this area. Low values of indices for gatherings of mites, as compared to renovated forest area, can indicate about the low biological activity of the investi-gated soils.
