    Opis:
    The future of humans and our planet, and food security, require innovative insights across many sectors of the economy (industry, agriculture, forestry, science and technology development). Reducing the use of chemicals, recycling carbon and recovering nutrients, caring for soil health, producing healthy food and adapting to climate change are the main challenges facing modern agriculture. The high proportion of soils low in organic matter, combined with manure shortages in some regions of Poland, poses a serious problem for maintaining the soil’s ability to perform productive and environmental functions. The use of selectively collected biodegradable waste, which contains significant amounts of organic matter, can be a key strategy for supplementing soil organic matter deficits. Green waste, kitchen waste, plant biomass produced in agriculture are valuable materials that, when processed through energy production,should become biofertilisers in line with the circular economy. Soil micro-organisms play an important role in the decomposition of organic matter and participate in the circulation and provision of nutrients to plants. Their role also includes fixing atmospheric nitrogen, stabilising soil aggregates, participating in the formation of soil humus and detoxifying soil from harmful substances present in the soil environment. Research to date confirms that biogas plant digestate can be a valuable fertiliser and has the potential to restore soil biological quality. There are virtually no reports indicating a negative effect of the digestate on the biological quality of the soil, especially when using digestate from agricultural substrates. This fact indicates that the potential of digestate in soil regeneration is significant, given its effects on soil biology, soil carbon and nutrient provision, and soil structure. It is more difficult to assess the impact of the digestate on soil biodiversity, especially the structure of the microbial population, which is strongly dependent on a number of soil, climatic and crop influences. An important aspect this review is the presentation of research needs for the potential of using digestate to regenerate soil and stimulate its biological life.

    Opis:
    The purpose of this study was to determine the basic physico-chemical properties of soil in silver fir stands with different stage of natural regeneration. The investigations were carried out in south-west part of Poland – in the Sudety Mountains. From 854 silver fir stands, 40 testing sites, varying in terms of habitat conditions and degree of natural regeneration, were selected. Soil samples were collected from litter (organic horizon – O) with a thickness of 7–15 cm and from mineral A horizon lying up to 20 cm below the organic horizon and were then analysed for pH, EC, C org., total N, exchangeable cations (Ca, Mg, K, Na, H and Al), soluble Mn, Fe, Zn and Pb as well as particle size distribution (samples from A horizon). The analysed soil samples are characterized by very high acidity and low content of bases. According to the performed statistical tests, none of the factors analysed within the samples tested has a significant impact on the natural regeneration of silver fir. The only dependence between potassium content in soil and the regeneration of silver fir in the Sudety Mountains is close to statistically significance.

    Opis:
    Traditional forest management as coppicing and coppicing-with-standard are recently considered as beneficial for biodiversity in woodlands. Cessation of coppicing leads to changes in stand structure and often loss of biodiversity. In contemporary Polish forestry coppicing is not applied, however some stands of coppice origin persist in Silesia until present. The overgrown coppice oak forests that cover the southern slopes at the foothills of the Sudetes Mountains (Silesia, Central Europe) are considered to be Euro-Siberian steppic woods with a Quercus sp. habitat (91I0): a priority habitat in the European Union, according to the Natura 2000 system. They support one of the largest populations of wild service tree (Sorbus torminalis Crantz) in Poland. In this study we investigated the relation of stand structure and trees parameters with environmental variables. The results showed considerable variability of stand volume, tree density and stems’ size correlated mostly with soil texture, but not nutrient content. We attributed it to soil dryness which seems to be the crucial factor controlling growth of trees. The natural regeneration of trees concentrated mostly on non-exposed sites on less acidic soils, but seedlings of wild service tree were present almost exclusively on most insolated sites, with shallow acidic soils. However, the regeneration of trees in sapling stage was restrained by browsing. Results suggest that maintaining of Sorbus torminalis requires protection against browsing, and some kind of active management is necessary to retain the observed stand structure with high proportion of wild service trees in stands on more fertile soils.

    Opis:
    In this paper the effect of different methods of soil scarification in a clear−cut area were studied. The following soil preparation techniques were applied: the soil cutter, the active soil plough, the traditional method with use of LPz plough, and the manual scarification of soil in circles surrounding the stem of the future young tree. The effect of management of the residual heaps of branches was also tested. Branches were either put in prisms in the original shape or, having been previously chipped, equally distributed over the entire area of the clear−cut. Additional studies focused on the effect of the time of clear−cut execution (winter or summer) on the condition of epigeic carabid communities. The least regressive effect to analysed communities was observed after the application of the point manual soil scarification. The clear−cuts carried out during the winter season, to a greater degree, favours the forest carabid fauna, preserving them in a structure more resembling the forest communities. More distinctive positive effect on the carabids is observed after putting the residual heaps of branches in prisms; the latter gives shelter for the carabid fauna and constitutes the refuge spots for it.
