    Opis:
    The alluvial soils in the Bóbr river valley, devastated by sand and gravel exploitation, were reclaimed for agricultural use. After reclamation treatment, the newly formed soil was very acid. Application of 5 Mg/ha lime elevated soil pH to 6-7, but during the following years, soil pH dropped again by about one half of the pH unit a year. Rapid drop in the pH level can result both from geological and soil-forming processes. Efficiency of mineral fertilizers applied in various combinations did not give the expected results and the yield of cultivated plants was not satisfactory. Mineral fertilization in various combinations did not result in the expected yield levels.

    Opis:
    The paper contains the results of eight-year-long studies on the runoff of nitrates from heavy soils used as croplands. The runoffs of nitrates from a drainage catchment and a catchment drained with ditches were compared. The drainage system was found to carry away twice as much water, with a five-fold higher concentration of nitrates and 20-fold higher load of nitrates, than the system of ditches. High runoff of nitrates (22 kg ha-1 annually) from the soils drained by drains was distributed quite evenly throughout the year, with maximum peaks in March and June. Nitrate runoff through the system of ditches was low (1.15 kg ha-1 annually), reaching maximum peaks in March and April (62% of the load), but disappearing in the summer.
    W pracy przedstawiono wyniki 8-letnich badań odpływu azotanów z gleb ciężkich użytkowanych ornie. Porównywano odpływ azotanów ze zlewni drenarskiej i zlewni odwadnianej rowami. Stwierdzono, że system drenarski odprowadza 2-krotnie więcej wody o 5-krotnie wyższym stężeniu azotanów i 20-krotnie wyższym ich ładunku niż system rowów. Z gleb odwadnianych drenami wysoki odpływ azotanów (22 kg rocznie z 1 ha) rozkładał się równomiernie w ciągu roku, z maksimum w marcu i czerwcu. Odpływ azotanów systemem rowów był niewielki (1,15 kg rocznie z 1 ha), z maksimum w marcu i kwietniu (62% ładunku) i zanikiem odpływu latem.

    Opis:
    Increase of sewage sludge production in Poland requires undertaking specific methods for their utilization and disposal. The reason is that sewage sludge, in addition to being rich in organic matter, and biogenic compounds such as nitrogen and phosphorus, which are beneficial from an agricultural point of view, also contain heavy metals, toxic organic pollutants such as persistent organic pollutants and polycyclic aromatic hydrocarbons, inorganic compounds such as silicates and clay, and pathogenic bacteria and other microbial contaminants. This implies problems with further use of such polluted sludge as fertilizer in agriculture. The aim of this paper is to analyze the possibilities and limitations of natural management of sewage sludge, taking into account their effects on the restoration and conservation of organic matter in the soil and the yielding of plants. In addition, the main methods of treatment of polluted sludge before introducing it into the environment are considered.

    Opis:
    Ectomycorrhizal (ECM) fungi and their symbiotic associations with forest trees are among major drivers of key ecosystem functions such as carbon and nitrogen cycling, plant nutrient and water uptake from soil, plant-plant facilitation/competition and diversity regulation via common mycorrhizal networks. Through their functional traits and interactions with both abiotic and biotic environment, they also significantly affect the process of open land colonization by trees as well as vegetation succession coupled with soil and ecosystem development. Here we review the role of ECM fungi in the early primary and secondary succession following major anthropogenic disturbances. Based on the examples of mine spoils and post-agricultural lands, we demonstrate key ecosystem services provided by ECM fungi in the processes of forest restoration. We point out ecological mechanisms and adaptations which underpin ECM fungal community successional interactions, particularly life histories, dispersal, spatial structure, host preferences, and sensitivity to environmental filters. We emphasize the need of better understanding the role of ECM fungi in the forest restoration practice as it seems crucial for afforestation success and biodiversity rehabilitation. Thus, ectomycorrhizal traits should be a prime consideration in afforestation and carbon sequestration polices, sustainable forest management and biodiversity conservation practices.

    Opis:
    The article focuses on the actual scientific and practical problem of accounting for the influence of meteorological and climatic factors in the technical and economic calculations in the field of environmental management. It has been proven that the introduction of scientifically sound and effective methods of using meteorological and climatic information in economic calculations significantly reduces the loss caused by weather conditions and improves the implementation of an optimal strategy for agricultural production on reclaimed lands. Such calculations are based on economic and statistical modelling of different variants that accounting for standard hydrometeorological information in the implementation of design, management and economic decisions. This increases the validity and reliability of calculations, as well as their compliance with the actual operating conditions of environmental and economic facilities. Consequently, this attracts increased interest of both public and private investors. Not only under such conditions is a sustainable development of environmental management sectors possible but also the adaptation to global climate change and additional benefits from the efficient economic activity in the new environmental conditions.

    Opis:
    Organic wood waste (sawdust, shavings, pieces of wood and bark), is widely used as a secondary raw material and, after composting, for soil fertilisation and substrate production in agriculture, horticulture, forestry, urban landscaping and rehabilitation of degraded land. However, problematic to process is wood waste that is very dirty with soil. They have limited calorific value and cannot be used in the R10 recovery process of land treatment benefiting agriculture or improving the environment. However, the morphological composition of these wastes indicates that they have good properties and can be used for agricultural use and for the reclamation of degraded land. The research involved wood waste with the code 03 01 99 (other unspecified waste from wood processing and the production of panels and furniture) generated during the preparation of deciduous tree logs for the veneer production process, and ashes from the burning of wood waste generated in the veneer production factory. The aim of the study was to assess the chemical composition of these wastes and the possibility of their agricultural use. In the samples of wood waste and ashes there was determined: pH; chlorines content; conductivity; hydrolytic acidity; content of micro and macroelements and heavy metals. The morphological composition of the waste is dominated by sawdust, with a smaller share of shavings, bark and earth parts, and a small addition of pieces of wood of various sizes. It is rich in easily bioavailble as well as total macroelements and is not contaminated with heavy metals. Analyzed wood waste has deacidifying properties, high sorption and buffering capacity. Studies have shown that the wood waste produced at the veneer factory, can be used as an organic fertiliser, a component of other organic fertilisers, for soil mulching, horticultural substrate and soil and land reclamation.The ash obtained from burning wood is strongly alkaline and rich in alkaline cations, mainly Ca, Mg and K. It is not contaminated with heavy metals. The ash can be used for soil deacidification and fertilization, especially for soil reclamation. The waste from the heap can be used as an organic fertilizer, a component of other organic fertilizers, for mulching soils and as a gardening substrate. However, the possibilities for non-agricultural (e.g.: for the production of pallet, particle board) use are limited due to the high proportion of earthy parts.
