From May to July in the years 1995-2000 studies on the numbers of density of Carabidae on two fields with different cultivation systems (intensive and conventional) were performed. Including other elements like kind of a crop and weather conditions during the investigations it was possible to compile a summary numerical index of main factors having the influence on the occurrence of Carabidae and being in a very good correlation with the number of these insects in agroecosystems.

The effect of alginate treatments with or without salicylic and oxalic acid as post-harvest coating in extending the postharvest life of plums (Prunus salicina L. cv. ‘Black amber’) and maintaining their quality were investigated. Plums were treated with 2% alginate coating with or without salicylic (1.0 mM) and oxalic acid (1.0 mM), and then stored at 0−1°C and 90 ±5% relative humidity for 40 days. The quality of plums was assessed at 10-day intervals by evaluating the following quality parameters: weight loss, soluble solids content, titratable acidity, firmness, respiration rate, ascorbic acid content, total anthocyanin content, total phenolic content and antioxidant activity. The respiration rate, weight loss and changes in quality parameters were much lower in coated plums as compared with the control. Alginate coating resulted in a significant reduction in weight loss of fruits. Alginate treatments with or without salicylic and oxalic acid were effective on delaying the evolution of parameters related to postharvest ripening, such as soluble solids content, softening and reducing respiration rate. At the end of the storage period, the edible coatings showed a positive effect on maintaining higher concentration of total phenolics, total anthocyanin content and antioxidant activity, which decreased in control plums as a result of over-ripening and senescence processes. The results suggested that the use of alginate enriched with salicylic acid could maintain considerably higher quality of fruits and level of bioactive compounds than other coating treatments during 40 days of storage at 0−1°C.

In the years 2008-2010 an environmental study was conducted, the objective of which was to estimate the current content of mineral nitrogen (nitrate V and ammonium) and sulphate sulphur in the soils of south-eastern Poland and to determine the relations of those elements with certain soil properties and cultivation treatments. 333 sampling points were designated, in which soil was sampled from 0-30, 30-60 and 60-90 cm depths. In the collected soil samples the Particle Size Distribution (PSD) was assayed with the use of Laser Diffraction Method (LDM), organic C using Tiurin method and pH in 1 mol KCl dm–3. Phosphorus and potassium were assayed using Egner- Riehm method (DL), mineral nitrogen (with division into the nitrate (V) and the ammonium form) with the colorimetric method using a flow auto-analyser, total and sulphate sulphur with the nephelometric method and assimilable magnesium after the extraction from soil in 0.0125 mol CaCl2 dm–3 with an ASA method. The highest content of nitrate (V) and ammonium nitrogen was noted in the 0-30 cm layer, irrespective of the spring or autumn date of soil sampling. The content of sulphate sulphur in the topsoil (0-30 cm) was the highest in organic and in heavy soils, but usually it did not differ significantly from medium, light and very light soils. The content of mineral nitrogen in the 0-30 and 0-90 cm layers was significantly and positively correlated with most of the assayed soil properties, whereas total and sulphate sulphur depended significantly and positively not only on soil properties, but also on the cultivation treatments.
