Vegetation, chosen properties of soil and mites (Acari) in the introductory phase of forest succession on the reclaimed post-military area Bydgoszcz-Jachcice

The aim of the study was to determine the physico-chemical status of soil, vegetation and fauna of soil Acari on the afforested post-military area By-dgoszcz-Jachcice. Two-year old Scots pine seedlings - produced at zoo-melioration treatment applied - were used for afferestation. Investigations were conducted in the year 2008. Experiment was run as two-factorial trial. The first row factor was the way of preparation of the area destined for afforestation: main plot which was previously sown with lupin (A) and the main plot without this sowing (B). The second row factor was the way of seedling production used at forest nursery school (subplots): 1 – compost with addition of bark, without mulching, 2 – compost with addition of bark, with mulching, 3 – compost with addition of sawdust, without mulching, 4 – compost with addition of sawdust, with mulching. Soils of the studied area were classified as rusty soils formed from loose sand. Occurrence of slightly loamy sand characterized by the clay fraction (< 0,002 mm) content, was found on all the plots in the range 4–6%. Differentiation of Corg content ranged from 10,5 to 14,4 g.kg-1. C/N ratio ranged from 17,0 to 23,6. All the plots were characterized by the ...

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

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 ...

Selected effects of revitalization of the reclaimed post-military area at forest District Źołędowo

The aim of the study was to compare the growth of silver birch (Betula pendula Roth) and Scots pine (Pinus sylvestris L.) as well as the state of soil mites (Acari) in two-year cultivations on the reclaimed post-military area at Forest Dis-trict Żołędowo. Afforestation was carried out with the use of two-year old birch and pine seedlings obtained from bare root nurseries (production with mulching and without mulching - traditional method). The experiments were conducted in 2010-2011 on Brunic Arenosols characterized by texture of loamy sand in the surface layer as well as by the strongly acid reaction. The experiments included the following variants: BrzC - birch cultivation which was afforested by the use of traditional seedlings (production of seedlings without mulching), BrzS - birch cultivation which was afforested by the use of seedlings produced with mulching, SoC - pine cultivation which was afforested by the use of traditional seedlings (production of seedlings without mulching), SoS - pine cultivation which was affor-ested by the use of seedlings produced with mulching. The cultivation of Scots pine was characterized by the better efficiency of planting (over 96 %). The mulching treatment - conducted at the nursery - had the positive ...
