Properties of grain and starch from varieties of wheat with different technological quality were measured. It appeared that besides the well known wheat properties such as high gluten content and medium enzymatic activity, the content of soluble carbohydrates is also important from the baking point of view. Moreover, medium solubility, not too low phosphorus content and high molecular mass of starch (isolated from wheat varieties) are essential to good quality of wheat.

Agronomic factors, and mineral fertilization in particular, have a strong impact on the quality of carrot roots. In recent years, researchers have begun to design eco-friendly agricultural practices that would stimulate the quality and yield of carrot roots. Our aim has been to analyse selected quality parameters pertaining to the chemical composition of carrot roots, and relate them to the application of different growth stimulators and cover crops. For this purpose, a field experiment was conducted in 2009-2011 investigating the effect of growth stimulators and stubble crops on the accumulation of chemical components in storage roots of carrot (cv. Laguna F1). The study included three growth stimulators: Asahi SL, Bio-algeen S 90 and Tytanit. Plots without any foliar application of these growth stimulators served as control treatment. Another factor consisted of the previous crop (spring barley) and stubble crops: tansy phacelia and a mixture of spring vetch and field pea, grown after the harvest of barley and then ploughed in. All the growth stimulators significantly reduced the NO3 content in carrot roots. Asahi SL significantly increased the phenolic content. The effects of the growth stimulators on the macronutrient content in carrot roots were statistically significant in the case of Mg and Na. Stubble cropping contributed to the reduction of nitrates and stimulated an increase in the content of phenolics as well as of P, K, Ca and Mg in carrot roots.

The investigations of the chemical composition of sands were conducted on the beach in Ustka and Czołpino. The Ustka is a typical tourist town and Czołpino is located in the Slovinski National Park away from urban or rural areas. The beach sediments in Ustka contain much more organic matter, nitrogen and phosphorus compounds as well as calcium carbonate than analogous deposits in Czołpino. The effect of sea water was manifested in the high content of organic matter in places having permanent contact with sea water. The content of the organic matter increased together with with the depth of settlings in these places. However more organic matter in surface layers was observed in regions more distant from the sea, because penetration of organic matter into the sediments is possible during precipitation. The concentration of ammonia nitrogen in the analyzed beach deposits increased with depth, what probably results from the lower oxygen content in deeper layers. It was confirmed that organic matter in sands of the beach in Czołpino is of natural origin, while in Ustka it is primarily of anthropogenic origin.

The investigated three dill cultivars Amat, Ambrozja, and Lukullus, were grown in five periods from spring to autumn. Harvesting was carried out when the plants reached 25 cm in height, i.e. within 36-45 days. The extreme usable yields of leaves reached 45-99 kg and of leaves with petioles 68-205 kg from 100 m2. These values constituted 36-44% and 57-87% of the commercial yield. The following yields of the components analysed were recorded from 1 m2: dry matter 76-194 g, total sugars and starch 13-31 g, dietary fibre 15-33 g, total nitrogen 4-9 g, ash 10-37 g, vitamin С 618-1290 mg, beta-carotene 19-55 mg, total chlorophylls 722- 1735 mg, and volatile oils 212-1142 mm3. The highest yields of volatile oils were obtained from the May and July sowings and of the remaining components from the April and August growing periods. In general, the cultivar Amat gave a higher usable yield of dry matter and also a higher yield of the analysed components.

Two methods of drying were applied: air-drying (temp.50 oC, time 5h) and freeze drying. The content of water in dried chive was about 3%. The quality of chive was tested before and immediately after drying and than after 3, 6, 9 and 12-months storage. Compared with air-drying, the freeze-drying method allows the production of dried chive characterized by more favourable organoleptic traits and chemical composition, although the organoleptic quality of air-dried chive may be regarded as fairly good. After 12-months storage of chive dried by these two methods the content of dry matter, total sugars, total nitrogen, ash, beta-carotene, and total chlorophylls and the degree of active acidity and ash alkalinity were not statistically different. During the drying procedure and the storing of dried chive losses of 24-34% concerned vitamin C, of 11-18% beta-carotene, of 19-21% - chlorophylls, and of 47-82% - volatile oils, always being greater in the air-dried product.

Comparative studies of ipe (Tabebuia spp.) wood photodegradation cause by treatment with outdoor and indoor UV-A light irradiation. A study on photodegradation of ipe (Tabebuia spp.) wood by UV A light has been carried out. Two types of lamps were used in the tests, i.e. a UVA-340 lamp with a wavelength of 290 - 400 nm, emitting light resembling natural light, an a UVA-351 lamp with a wavelength of 300 - 400 nm, imitating light found indoors penetrating through window panes. Colour of the samples was measured using a Datacolour 600 spectrophotometer prior and after 1,5, 10, 25, 50 and 100-hour irradiation. Characterization of investigated material included determination of its chemical components. Despite the fact that ipe wood contains high concentrations of components playing an important role in the photodegradation process (e.g. 37.2% lignin) the detected changes are minor and do not exceed 1 point. The change in colour (∆E) for ipe wood surface was mainly caused by changes in the chromatic coordinate (b*) and the lightness coordinate (L*). Greater changes occurred under the influence of a UV-340 lamp emitting the type of light resembling that found outdoors.

Shallot is one of the vegetables, which are especially abounding in flavonoids, phenolic acids and other compounds with antioxidative properties. Among Allium vegetables it is also distinguished with good storage ability. The studies conducted in the years 2007–2009 included the assessment of dry matter, flavonoids and phenolic acid contents in shallot bulbs immediately after harvest and drying off, as well as after long-term storage (5 months in the temperature 0–1°C and humidity of 86%). The studies concerned 3 cultivars of shallot: ‘Ambition F1’, ‘Bonilla F1’ and ‘Matador F1’. The bulbs of these cultivars were obtained from seedlings planting. For chemical analyses bulb samples with the diameter of 25–30 mm were selected, as such constituted the greatest participation in the obtained yield. The contents of total and reducing sugars, flavonoids (converted into quercetin), as well as phenolic acids (converted into coffeic acid) were determined in fleshy scales, whereas in dry scales only the contents of flavonoids and phenolic acids were determined. The dry matter of fleshy scales in the examined shallot cultivars was on average 16.65%. From among three examined cultivars the bulbs of ‘Bonilla F1’had significantly greater dry matter (18.03% on average). The contents of total sugars in shallot bulbs was on average 6.32% immediately after harvest and 5.71% after 5 months of storage. Similarly as in the case of dry matter, the bulbs of ‘Bonilla F1’ cultivar turned out to be the most abounding both in total and reducing sugars. The examined cultivars significantly differed in the contents of flavonoids and phenolic acids both in dry and fleshy scales. In all the cultivars the dry scales contained more than 50 times more flavonoids and more than 34 times more phenolic acids, as compared with fleshy scales. Long-term storage of shallot bulbs significantly affected the decrease of flavonoid contents, slight decrease of total sugars, but a significant increase of phenolic acids. From among the examined cultivars ‘Ambition F1’ was characterized with the lowest contents of all the analyzed components.

The present experiment studied effects of systematic, differentiated mineral fertilisation and liming on the amount of N-NO3-, K, Mg, Ca, Na ions lost from the 0-40 cm soil layer during meadow sward vegetation period as a result of leaching. The highest amount of filtrate was observed in the control object for both series, i.e. without liming and with liming. During vegetation, the level of filtrate amounted to, respectively, 224 and 213 mm on the average. The lowest pH of the lysimetric water was found in the objects fertilised with double doses of nitrate and urea. Calcium was leached from the soil to the highest degree, i.e. from 38.4 mg/lysimeter in the object unilaterally fertilised with phosphorus (the series with liming) to 231.6 mg/lysimeter on the object fertilised with 180 kg N in the form of ammonium nitrate (the series without liming). Leaching of potassium depended on the applied fertilisation with this element. The lowest loss of magnesium was found in the object unilaterally fertilised with phosphorus; respectively 12.5 mg Mg/lysimeter for the series without liming and 14.1 mg Mg/lysimeter for the series with liming.

This paper presents analysis of meteorological, hydrological and hydro-chemical records collected in the years 1995-1998 in the upper catchment of the Grajcarek (the Small Pieniny Mountains). It was found that irrespective of water stages, concentrations of chemical components were at an average level. The loads, however, were significantly diversified. At lower stages, they constituted 4-7 per cent of the annual load, and at extremely high stages 23-33 per cent. The lower loads of all components were flowing out of the catchment A. The authors link this fact with the high afforestation of this basin. From the above data the conclusion can be drawn that the land use of a catchment has an effect on the chemical components of the runoff. It has particular importance in the case of mountain areas in view of the threat of water erosion.
