Soil material was taken from pots after two years of the study involving the investigation of two parameters: I – liming (without liming and with liming according to 1 unit acidic reaction applied as CaCO₃; II – organic fertilization: waste activated sludge from Siedlce, broiler chicken litter and brown coal from the Turów mine). The organic fertilization was applied in a dose of 2 g of organic carbon per 1 kg of soil material. The total content of phosphorus was determined by the ACP-AES method after earlier decomposition of the organic substances by the ‘dry combustion method’. The investigated fractions of phosphorus were separated by the Chang-Jackson method using the modification of Peterson and Corey. The organic materials used in this experiment significantly differentiated the content of total phosphorus and its fractions in the analysed soil materials. The highest content of total phosphorus was determined in the soil materials fertilized with broiler litter and waste activated sludge from Siedlce, and the lowest in the soil material without the addition of any organic materials. In all investigated soil materials the highest levels of extractable phosphorus was determined in the fraction of aluminium phosphate and the lowest in the fraction of occluded phosphate.

For several years now the Polish Normalisation Committee (PKN) has been angaged in the process of introduction (and implementation) of international standards complying with the Internationsl Standard Organsation (ISO) into the set of of Polish Standards.At present, in the PKN Commission of Soil Physics, a number of such standards are being prepared (translated) -including a very comprehensive standard dealing with partiele size distribution determination in soil material-ISO 11277 [6], Some principles and requirements included in this standard differ significantly from those commonly accepted and widely in use now in numerous pedologie laboratories in Poland [7,8]. Below there are some of the most important differences: (1 ) the requirement to remove organic matter from test samples (using 30% v/v solution of H2O2), (2) the requirement to remove water soluble salts and gypsum (to electrical conductivity 0,4 dS/m), (3) sample dispersion process must be longer than 18 hours. Many other requirements, of relatively lesser importance, in many cases also do not correlate with those commonly accepted in our laboratories.

Four pedons of Alfisols were selected from the Experimental Station Mochełek to study chemical composition of the soil material. The study area is located in the south-western border of the Krajeńska Upland, on the border of two geomorphological formations: erosion surface of floating waters (fluviglacial formation) and rolling ground moraine (glacial material). The investigated soils were classified as Typical Hapludalfs (pedon 11,21 and 26) and Typical Glossudalfs (pedon 7). Chemical composition was analysed using the following methods: fusion with Na2CO3 and dissolving in the HF and HCIO4 mixture. Results were presented in an oxide form and molar ratios (SiO2/R2O3; SiO2/Al2O3; Si02/Fe203; Al2O3/Fe203) were calculated. In the studied soils, the content of SiO2 was from 78.21 to 90.00 %. The lowest SiO2 content was found in the illuvial horizons. Otherwise the illuvial process influenced Al2O3 and Fe2CO3 distribution, the highest amounts of which were found in the illuvial horizons. TiO2 (0.15 to 0.63 %), had similar profile distribution to K2O (1.74-3.88 %) and Na20 (0.61- 1.05 %). CaO and MgO contents were the highest in the parent material, including CaCO3 (pedon 11 and 26). However, the highest amount of MnO was observed in the surface horizons (0.56-0.58 %). Chemical composition of the studied soil material indicated a large influence of the illuvial process and particle-size on the total content and profile distribution of the analysed soil. However, the evident influence of parent material from which the analysed soils were formed, was not found.

Rainfalls, topographic features, and catchment management are the main factors that affect the amounts of soil denudation. Studies carried out within loess catchment, being ploughed and covered with orchards, were aimed at evaluating the water erosion intensity and assessing the anti-erosion effi ciency of in-field retention reservoirs. After intensive rainfalls in 2001/2002–2003/2004, the quantity of erosion damages was assessed on a base of recorded erosion landforms and capacity of the soil material sedimented in reservoirs. Analysis of translocated soil quantities in micro-catchments of particular reservoirs confirmed the infl uence of catchment management on water erosion processes. Great importance of in-field water reservoirs in retention of the eroded soil material was proved.

This research aimed to assess the effect of fertilization with sewage sludge and their mixtures with peat on maize biomass yield and its zinc concentrations, as well as Zn contents in soils with various textures. The research was conducted as a two-factor (soil and fertilization), three-year pot experiment (2003-05). The soil material used for the experiment revealed the texture of weakly loamy sand (Soil I), sandy silt loam (Soil II) and medium silt loam (Soil III). The sewage sludge originated from two different municipal mechanic and biological treatment plants. The mixtures of sewage sludges with peat were prepared by mixing the organic material in weight ratio 1:1 in conversion to dry matter. Under the experimental conditions fertilization with sewage sludges and sludge mixtures with peat affected maize biomass yield more positively than fertilization with mineral salts. The smallest yield of biomass, irrespective of applied fertilization, was obtained when maize was cultivated in weakly loamy sand (Soil I). In comparison with organic materials and farmyard manure supplied to the soil, the greatest quantities of zinc were assessed in maize fertilized with mineral salts, irrespective of soil type. Sewage sludge mixtures with peat, as compared with sewage sludge used separately, affected maize biomass yields slightly better but had a similar effect on zinc concentrations in the plant biomass. The least of zinc mobile forms were determined in medium silt loam (Soil III). Following the application of organic materials but irrespective of the soil, the content of mobile zinc forms was significantly smaller than the content assessed in the soils from mineral salt treatments.

The distribution of polycyclic aromatic hydrocarbons (PAHs) in plant and organic soil from 14 peatland sites in NE Poland and 7 peatland sites in SE Poland have been investigated. The total PAH concentration in the leaves of Ledum palustre collected from peatlands in NE Poland ranged from 232 ng/g to 1523 ng/g and was higher than the total PAH concentration in pine needles (Pinus sylvestris) taken from those same peatlands (the values ranged from 181 to307 ng/g). A similar trend was observed in the case of plants from the peatlands in SE Poland, except that the overall PAH concentration in the majority of the plant samples was found to be higher than those found in NE Poland. Phenanthrene and fluoranthene had the biggest share in the overall PAH concentration in all the peat and plant samples. The lack of 5- and 6-ringed PAHs in the plant and soil material indicates the lack of any direct emission sources of these compounds in regions adjacent to those examined in the study. Total sum of PAH pollution levels in peats and plants as well as vertical distribution of the concentrations in the soil profile of particular study sites integrates long-range pollution sources. To compare natural and antropogenic PAH input in the pealtlands, we have used parent PAH ratios: ANT/(ANT&PHE); FLT/(FLT&PYR). Our data suggest that PAHs with four and more rings do not allow a simple segregation into combustion or petroleum sources.
