Opis:
The effect of hard coal fly ash applied on surface of forested (formerly arable) rusty soil on chemical composition of soil surface horizons was evaluated in field experiments conducted between the years 1992-1995. The application of fly ash at the dose 15, 30, 60 and 120 t ha-1 on the soil surface caused a decrease of acidity of soil surface layer which was dependent on the fly ash rate. The deacidification of soil lasted only two years. The application of fly ash increased also the content of macro- and microelements in the soil as well as in Scotch pine needles.

Opis:
Research was carried out in 1998 on the area of 10 allotments situated within the limits of the city of Lublin. Representative soil samples, as well as samples of white cabbage and carrot roots were collected. Content of lead, zinc, and copper were analysed in the samples. On the basis of chemical analysis, it was observed that quantities of lead and zinc were usually higher than average in the same type soils in non-polluted areas. Copper content in the soil did not exceed the average values. The natural content of metals was usually not exceeded in plants. However, samples of white cabbage taken from the "Nasza Zdobycz" and "Sygnał" allotments, where the amount of lead was higher than I mg kg-1 of dry mass were an exception.

Opis:
This study was based on tuber samples from the field experiment in 1996-1998 on weak loamy sand soil in a system of randomised sub-blocks. The experimental factors were: ways of nursery and varieties (Swojecka, Kulista Czerwona IHAR, Kulista Biała IHAR). Herbicide application elevated both cadmium and nickel contents in Helianthus tubers as compared to control. Tubers of Swojecka Czerwona cv. were characterised by the lowest accumulation of cadmium and nickel, those of Kulista Czerwona IHAR cv. by the highest content of nickel, and those of Kulista Biała IHAR by the highest level of cadmium.

Opis:
Trace elements contents analyses were made in tuber samples collected from the field experiment in 1996-1998 in Experimental Station, Parczew, on weak loamy sand soil. The following experimental factors were taken into account: their cultivation technologies; two potato varieties (Aster and Drop). The lead content in very early potato tubers appeared to be higher than the permissible one in all study years. The highest lead content was found in young tubers harvested on 60th day after setting. Along with the delay of harvest, the lead level tended to be lower. Tubers harvested on the 75th day after setting accumulated the most strontium, those physiologically matured had the lowest level of this element. All types of coverage applied in the study contributed to the increase of lead content in tubers of very early potato varieties as compared to traditional cultivation. Neither cultivation technologies nor variety features modified the strontium accumulation in tubers.

Opis:
The efficient use of water is increasingly important and proper soil management, within the specificities of each region of the country, allows achieving greater efficiency. The South and Caparaó regions of Espírito Santo, Brazil are characterized by relief of ‘hill seas’ with differences in the degree of pasture degradation due to sun exposure. The objective of this study was to evaluate the least limiting water range in Udox soil under degraded pastures with two faces of exposure to the sun and three pedoenvironments. In each pedoenvironment, namely Alegre, Celina, and Café, two areas were selected, one with exposure on the North/West face and the other on the South/East face. In each of these areas, undisturbed soil samples were collected at 0-10 cm depth to determine the least limiting water range. The exposed face of the pasture that received the highest solar incidence (North/West) presented the lowest values in least limiting water range. The least limiting water range proved to be a physical quality indicator for Udox soil under degraded pastures.

Opis:
Concentration and profile distribution of heavy metals was investigated as contamination indicators of the forest soils formed from glacial deposits of the South Podlasie Lowland. The study was carried out on thirteen soil profiles situated a hundred meters from the road. The highest content of heavy metals was found in the organic horizons of the investigated soils. The mean content of Mn, Zn, Cu, Pb, Ni, Cr in the investigated soils were: 556.7, 72.9,15.5, 63.5,13.8, 16.5 mg/kg d.m. of the soil, respectively. In the mineral-organic and mineral horizons of the investigated soils heavy metals were present in quantities which were close to natural. The podzol soils, podzols and rusty soils developed from sands contain less heavy metals than the soils lessivés, black earth and deluvial soil. The Mn, Zn, Cu, Pb distribution in the soil profiles is influenced by the soil forming processes. The distribution index of the examined metals distribution in the genetic horizons testify to it.

Opis:
The author investigated a 0-3 cm layer of two forest brown soils: brown acid and brown leached. These forest soils were under handsome beech trees (Fagus sp.) between 100 and 120 years old. The author compared the chemical properties of the soils. The soil existing near the tree trunk (1 m2 of surface, strongly washed by rain water polluted by chemical substances) and the soil existing under the tree umbrella (40 m2 of surface in the area of the tree-tops, washed poorly by rain water). This comparison showed changes in these properties, dependent upon the degree of atmospheric contamination. It was found that, at the same level of atmospheric contamination, higher changes of properties were found in brown leached soil than in brown acid soil. Less acidified soils (with alkaline or neutral pH reaction) are more suitable in these researches. The investigations of the forest soil layer 0-3 cm (12 soil profiles) showed that changes in their chemical properties in relation to tree trunk-tree umbrella can be the basis of assessment of the degree of atmospheric contamination.

Opis:
The objective of the study was to evaluate zinc and lead contamination in the upper, organic layer of the soil around zinc and lead smelting plant KGH "Bolesław" in Bukowno near Olkusz. The study material were samples of the upper layer (0-5 cm) of the soil collected at the distance of 10, 25, 50, 100 150, 200, 250 m, and further from each of the 250 m up to 3 000 m sections in 8 directions: N, NE, E, SE, S, SW, W, and NW. The most contaminated soil samples were found at the distance of up to about 1 000 m from the subject plant. The most polluted is the NE and SW area. Pollution of the NE area is related to wind direction. The SW area could be a zinc and lead ore outcrop, or else, it was contaminated when used as a dumping ground for the waste from the plant in the past. Heavy pollution of this area with zinc and lead could cause serious damage to living organisms in the area close to the plant.

Opis:
In the result of geomechanical transformations associated with the activity of open cast brown coal mining, some changes in air-water relations may occur on arable land adjacent to these regions usually referred to as hvdrological alterations. However, they do not always need to result in soil degradation, i.e. in the deterioration of their production potentials. This will often depend on the distance of fields from the workings, value of the arable land (soil quality class), type of water management, etc. On the basis of long-term studies carried out in the area of operation of two brown coal mines - KWB "Konin" and "Adamów" - on arable land and grasslands of over 60 villages on the total area of 30 thousand hectares it was possible to develop evaluation criteria for the extent of soil degradation and work out principles for compensation payments for farmers. Three zones and appropriate sub-zones of soil susceptibility to drainage were determined and clear and simple criteria for the estimation of the extent of arable land and grassland degradation were worked out. Furthermore, the authors proposed simple and readable systems to calculate compensatory payments to be paid to farmers taking into account the state of soil degradation, value of agricultural land (price of 1 ha of land of appropriate class) and the area of damaged land. The degree of soil degradation, both of arable land and grasslands, ranged from 10 to 30%. In the case of grasslands, additionally, an appropriate sum of money was allocated to compensate for sward recultivation.

In the study, the content of heavy metals such as Pb, Cd, Ni, Cu, Zn and Mn in the soils collected from various regions of the Lublin Voivodeship was examined. The examined soils were light medium soils. Content of individual elements was determined by the AAS method in the extracts of 1 M HCl. The analysed soils were poor in copper and manganese. Their concentration and the concentration of lead, cadmium and nickel was in the lower realms of the range natural for light soils formed from sands. Only the content of zinc was fairly high in the above soils, frequently as high as the first degree of contamination.

Opis:
The paper characterises total concentrations of Cd, Cu, Ni, Pb, Zn in the surface layers (0-20 cm) of agricultural soils in Poland (48620 soils samples) and Lublin region (3829 soil samples). The results for Lublin region are expressed in terms of the degree of metal pollution as compared to contamination in the rest of the country. The average concentration of Cd, Cu, Ni, Pb and Zn (in mg kg-1 of soil) in the A horizon of agricultural soils in Poland and in Lublin region (values in parenthesis) are as follows: 0.21 (0.17); 6.5 (4.9); 6.2 (6.6); 13.6 (10.7); 32.4 (23.3). About 79% of the agricultural soils in Poland are characterised by a natural (0°) content of heavy metals while 17.6% contain elevated level (10) of these metals. In the Lublin region it is 91.9% and 6.7%, respectively. About 3% of the Polish soils (1.4% in the Lublin region) exhibit various degrees of contamination with heavy metals. This includes heavy (IV0) and very heavy pollution (V0) which is found in up to 0.4% of the agricultural land and up to 0.2% in the Lublin region.

Opis:
In the pot experiment the effects of contamination of diesel oil of proper brown soil developed from light loamy sand on microorganisms abundance and activity of soil enzymes were studied. Diesel oil was applied at the following rates: 0, 2, 4 and 6 cm3 kg-1 of the soil. Trial was performed in two experimental series: amended or not amended with straw. It was found that soil pollution with oil stimulated development of Azotohcicer sp., oligotrophia copiotrophic and ammonitiers bacteria; whereas inhibited fungi proliferation, dehydrogenases and urease activities and did not affect actinomycetes number. Diesel oil addition to the soil reduced positive effects of straw on microbiological and biochemical soil properties. Oil pollution adversely affected growth and development of triticale. Straw amendment diminished level of oil toxicity to triticale.

Opis:
Soil degradation generates the need for reclamation measures. Bioaugmentation represents a promising method to treat degraded soils. The introduction of microorganisms into the soil often requires immobilisation. Porous media, such as biochar, have been used for the purpose. The introduction of individual bacteria into the soil requires the choice of a suitable medium to ensure high bacterial survival rate and effective bioaugmentation. The possibility of immobilization of Bacillus subtilis, Pseudomonas fluorescens, Azospirillum brasilense and a bacterial consortium by means of encapsulation in alginate with the addition of biochar, nanosilica, perlite or vermiculite was analysed in the study. The best effects of B. subtilis immobilization were obtained with alginate with 5 ml of biochar, P. fluorescens - with 25% (v/v) perlite and vermiculite, while A. brasilense - with 25% (v/v) alginate and 50% (v/v) perlite. The most effective immobilization of the bacterial consortium was achieved using alginate with addition of 50% (v/v) of biochar.
Degradacja gleb generuje konieczność podjęcia działań rekultywacyjnych. Bioaugmentacja stanowi obiecującą metodę oczyszczania gleb zdegradowanych. Wprowadzenie mikroorganizmów do gleby bardzo często wymaga zastosowania immobilizacji. Do tego celu wykorzystuje się porowate nośniki, takie jak biowęgiel. Wprowadzenie poszczególnych bakterii do gleby wymaga doboru odpowiedniego nośnika zapewniającego wysoką przeżywalność bakterii oraz umożliwiającego efektywną bioaugmentację. W niniejszej pracy określono możliwość immobilizacji Bacillus subtilis, Pseudomonas fluorescens, Azospirillum brasilense oraz konsorcjum bakteryjnego poprzez kapsułkowanie w alginianie z dodatkiem biowęgla, nanokrzemionki, perlitu lub wermikulitu. Najlepsze efekty immobilizacji B. subtilis uzyskano z zastosowaniem alginianu z dodatkiem 5 ml biowęgla, P. fluorescens z wykorzystaniem 25% (v/v) perlitu i wermikulitu, natomiast A. brasilense 25% (v/v) alginianu i 50% (v/v) perlitu. Najefektywniejszą immobilizację konsorcjum bakteryjnego uzyskano z wykorzystaniem alginianu z dodatkiem 50% (v/v) biowęgla.
