The article characterizes the importance of water in the production and management of potato crops. Potato is a species with a relatively low transpiration coefficient, but the high biomass yield obtained from the surface unit in a short time span determines the high water needs set for 350 to 450 mm of rainfall during the growing season. The work determines the potato water requirements in individual phases of plant development, as well as analyzed the amount of atmospheric precipitation in Poland in recent years. The influence of irrigation on the yield and changes in the quality of potato tubers was also determined. In modern agrotechnics, natural rainfills replenished more and more often with irrigation allow to obtain very high potato yields. Methods improving the use of water needed for irrigation on potato plantations include: retention of winter water resources in reservoirs, cultivation on soils with high retention, compliance with optimal agrotechnical dates, cultivation of Inżynieria Ekologiczna Ecological Engineering Volume 19, Issue 6, December 2018, pages 14–25 https://doi.org/10.12912/23920629/95273 Received: 2018.09.15 Accepted: 2018.11.02 Published: 2018.12.01 „Europejski Fundusz Rolny na rzecz Rozwoju Obszarów Wiejskich: Europa inwestująca w obszary wiejskie”.

Due to the widespread availability of petroleum derivatives, they are the most common cause of soil and water pollution. Physical, chemical and biological methods are used to remove hydrocarbon pollution. Comparing the abovementioned methods, it can be stated that the biological ones are currently the most commonly used in the liquidation of hydrocarbons contaminating the soil and water environment, not only in the in-situ remediation process (in the place of contamination), but also in ex-situ remediation (the removal of contaminated soil from the site contamination and further processing in the recovery process). The biological method associated with physical methods was used to eliminate pollution of post-industrial land contaminated due to unsuitable oil management both during its existence and after the end of industrial activity in the area. For the soil and earth remediation, biopreparation based on indigenous microorganism was used. During the remediation process, the decrease in the hydrocarbon content and the effectiveness of the biopreparation used was observed.

The area of the Śląskie Voivodeship for over two hundred years has been subjected to a strong industrial anthropopressure associated with the extraction and processing of metal ores, hard coal and energy. The effect of these activities was and still is the strong acidification of soils in the whole area of the province and higher than for Poland the average content of cadmium and lead. To counteract the effects of excessive soil contamination, the Regional Chemical and Agricultural Station in Gliwice (OSChR) and the Silesian Agricultural Chamber in Katowice undertook activities aimed at introducing a liming program co-financed from the funds of the Voivodship Fund for Environmental Protection and Water Management in Katowice. Implementation of the program was possible thanks to extensive expertise based on the results of agrochemical research carried out by OSChR in Gliwice. The launched and continued program brings real results as evidenced by the assessment of soil research results from the years 2014–2017 as compared to the 2004–2009 situation. Thus, the program has now become the only regional venture of its kind in Poland.

Among the officials of local governments responsible for urban forest, a wide range of society, and even among people professionally dealing with trees, there are often conflicting opinions about the use of modern technology for their diagnosis. Knowledge of its applicability is crucial in making decisions about mature and aged trees. The work was based on many years of experience of the authors in the diagnosis of trees. It was supported by examples from practice and also presented research and opinions of the best specialists in this field in the world. Each device has its strengths and weaknesses. The ability to use it without proper interpretation of the obtained results may lead to wrong conclusions and thus the decisions made. The use of simple diagnostic equipment has been discussed. Instrumental diagnosis supports the correct assessment of trees, but requires a sufficient knowledge and experience in interpreting obtained results.

Field experiment was conducted to analyze the growth dynamics of the oilseed rape and the filling of pods in two types (cv. Brendy population and cv. Primus F1 hybrid). The variant of quantitative growth analysis for a single plant was chosen. It was found that the hybrid variety has a higher tolerance to biotic stresses that may occur (pests and diseases) and periodic drought (increased water storage capacity). However, it created a lower dry weight and lost the leaves earlier. Population produces more dry matter, earlier it establishes a fixed proportion of each organ within, but is exposed on spill on the seeds. As a result, the difference in the yield of the seed was 0,4 t ha-1 in favor of the hybrid. Hybrid oilseed rape breeding should strive to early establish a rigid proportion of the various organs of the dry weight of the plant.

The paper presents the results of tests for the production of fuel granules from fine-grained coal fractions. The raw material used for the research was selected fine coal fractions – coal sludge and coal flotation concentrate, obtained from the process of coal enrichment in hard coal mines. The aim of the work was to develop a recipe and parameters for the process of granules production with adequate physicochemical properties, enabling their transport, dosing and gasification in a fixed and fluidized bed system. The work determined the share of specified components (coal sludge, coal flotation concentrate and binders) and the conditions of granulation using the agglomeration technique in the disk granulator. It was found that a mixture consisting of 30% wt. coal sludge and 70% wt. coal flotation concentrate with the addition of 3% Portland cement in relation to the dry matter of carbonaceous components, allows obtaining granules meeting the requirements for their gasification in IChPW research installations (fluidized bed and fixed bed gasification) in terms of calorific value, ash content, particle size distribution and mechanical strength.
