Opis:
Carabidae were used as a zooindicator to evaluate different soil preparation techniques applied to farmland prior to afforestation: full deep ploughing (MBS), full ploughing to a depth of 25 cm using agricultural tractor (OR), full ploughing to a depth of 25 cm with subsoil ploughing (ORP) and raising of soil horizons A0 and A1 (NW). The studies were conducted 4 and 5 years after afforestation. The total number of caught beetles was 13 869 individuals from 68 species. Taking into consideration the trapping ability, mean individual biomass and colonization by xerophylous or forest species the deep ploughing BMS and subsoil ploughing ORP was found to have the greatest impact on the carabid recolonisation rate and site degradation.

Opis:
The quantitative and qualitative analysis of mycorrhizae was done for Scots pine in plantation established on post−agricultural land. The state of mycorrhizae depended on the applied method of soil preparation (full deep ploughing, full ploughing with subsoiling, full shallow ploughing and ridge formation) as well as the presence and density of introduced land improving species (5, 3, 1.5 thousand/ha).

Opis:
Forest ecosystems established on former agricultural lands are affected by pathogenic factors described as „chain disease”. The regeneration of such ecosystems lasts longer (ca by 30 to 50 years) as compared with the regeneration rate of stands growing on forest sites. One of the restoration methods of forest ecosystems is the leaving of fallow lands for natural succession. The paper is an attempt to find the dynamics and direction of changes that undergo in various developmental stages of natural succession on former agricultural lands by using zooindication indicators.

Opis:
The dynamics of soil respiration activity was measured in four soil preparation and admixture variants with pine admixed with phytomelioration and biocoenotic species. In total, there were 16 different variants. The measurements were carried out in May/June 2005 using a CO2 concentration analyser AirTECH 2005−PA. Additionally, air and soil temperature were measured. The obtained results show that soil respiration activity depends on soil preparation method. The greatest soil carbon dioxide efflux was detected on the plots prepared by agricultural plough, while the lowest − on the plots prepared by BMS plough. The most intensive respiration activity of soils occurred on the plots with 7,000 pines admixed with 1,500 species of phytomelioration and biocoenotic plants. The lowest carbon dioxide efflux was detected on the plots with 7,000 pines admixed with 3,000 phytomelioration and biocoenotic species. Additionally, soil and air temperatures turned to have a significant impact on soil respiration activity.

Opis:
Changes in silvicultural and phytopathological parameters have been assessed in a 55−year−old pine stand established on post−agricultural land after 30 years from the application of three types of cutting (selective 10%, line every 4 and every 6 row) in this stand. It has been demonstrated that root rot causes changes in number and volume of merchantable timber of trees when protective treatments to stumps using the fungus Phlebiopsis gigantea are not applied during first improvement cuttings.

Opis:
Young forest plantation established on abandoned agricultural land were compared to spontaneously developing young forest in order to evaluate their impact on biological activity of the soil. The study area was planted by pine trees in number 7 thous. per hectare. Aditionally, phytoameliorative tree species were planted singly on these plots in the following number: 1,5 thous., 3 thous. and 5 thous. per hectare. Some plots were pine monoculture.The following variant of site preparation prior to afforestation were used: agricultural ploughing (deep to 25 cm), agricultural ploughing with countersinking, deep ploughing (to 40−50 cm) and countersinking with ridges. All applied site preparation technics have detrimental effect on soil mesofauna. Collembola communities of five−year pine plantations are impoverished form of open area fauna. Phytoameliorative tree species do not accelerate soil fauna developement during the first years of secondary forest succession. Developement of soil fauna on abandoned agricultural land has been noticeably promoted by spontaneous succession of forest ecosystem.

Opis:
It has been proposed that artificial gaps are to be established in young pine stands by cutting an appropriate number of trees around the centres of infection (1−3 dying trees) and introducing Phlebiopsis gigantea to stumps. The treatment limits or significantly reduces root rot effects in trees and the risk of dis− ease development that may follow. The initiation of the biocoenotic nature of changes in pine monocultures ensures stand conversion (reconstruction) supported with the processes of natural succession.

Opis:
The focus of the research was on the effect of inoculation with the ectomycorrhizal fungus Thelephora terrestris on changes in mycorrhizal structure and growth parameters of Scots pine (Pinus sylvestris L.) seedlings. Before planting on post−agricultural land, the seedlings were grown under laboratory conditions for six months, at two different nitrogen fertilization rates [Hilszczańska, Sierota 2006a]. Mycorrhizae formed by T. terrestris dominated in the mycorrhizal structure during two growing seasons after planting irrespective of the growth variant applied. However, their higher percentage was detected in seedlings artificially inoculated with T. terrestris mycelium. The inoculation did not limit mycorrhiza formation by other mycorrhizal fungi. No significant differences in parameter values were found between inoculated and non−inoculated seedlings.

Opis:
The changes of N, P, K, Ca and Mg content in Scots pine needles over 4 years of the experiment were estimated in 2 treatments – inoculated in laboratory with the ectomycorrhizal fungus Thelephora terrestris and non inoculated (control). The seedlings were grown in a greenhouse for one season and then planted out into post−agricultural soil. Statistically significant differences were found only for Mg concentration in needles of two−year−old initially inoculated seedlings. For both treatments N and K concentration differed between all analysed years of growth. In the case of P and Ca concentration differences were found neither for treatments, nor for years. Four−year−old inoculated seedlings had lower concentration of all investigated nutrients with the exception of Ca. In both treatments the concentration of nutrients was at optimal level for four−year−old seedlings’ growth. Obtained results suggest that environmental conditions as well as plant metabolism may influence the nutrient concentration in the needles more strongly than their uptake by ectomycorrhizal symbionts on the roots.
