Oznaczono zawartość kadmu i ołowiu w warzywach, zbożach, owocach i glebie z upraw polowych uznanych jako wolne od zanieczyszczeń przemysłowych, w warzywach z upraw narażonych na zanieczyszczenia oraz w warzywach i glebie z upraw szklarniowych.
The content of cadmium and lead was measured in vegetables, fruit, cereals and soil from areas exposed and non-exposed to industrial pollution and in vegetables and soil from greenhouses. The elements were measured after dry mineralization by atomic absorption spectrophotometry following extraction of complexes from APDS into the organic phase (MIBK). Lead and cadmium were determined in 482 samples of vegetables, 101 fruit samples, 132 cereal samples and 297 soil samples. In the vegetables from the areas not exposed to industrial pollution lead content was below the detectability range (< d.r.) to 576.1 µg/kg, and cadmium was from < d.r. to 73.5 µg/kg. In the vegetables from areas exposed to industrial pollution lead was from 9.3 to 1044.0 µg/kg and cadmium from < d.r. to 552.3 µg/kg and cadmium from 2.3 to 132.5 µg/kg. In the soil from greenhouses lead was found in amounts from 17.5 to 212.0 mg/kg of air dry mass (adm), and cadmium from 125 to 750 µg/kg of adm. In soil from vegetable gardens lead was from 3.3 to 15.3 mg/kg of adm., and cadmium from

The content of copper and zinc was determined in vegetables, fruit and cereals derived from areas exposed or non-exposed to industrial pollution and from greenhouses. The elements were determined after dry mineralization by atomic absorption spectrometry immediately from mineralisate solution. Copper and zinc were measured in 506 samples of vegetables, 101 fruit samples and 117 cereal samples. In the vegetables from areas not exposed to industrial pollution the copper content was from 0.10 to 6.69 mg/kg, and zinc content was from 1.10 to 27.90 mg/kg. In the vegetables from areas exposed to this pollution copper was found in amounts from 0.10 to 3.26 mg/kg and zinc from 0.88 to 27.90 mg/kg. In the vegetables from green-houses copper amounted to 0.14 - 1.20 mg/kg and zinc from 1.00 to 10.60 mg/kh. In fruit samples copper was found in amounts from 0.04 to 7.01 mg/kg and zinc from 0.60 to 17.30 mg/kg. In cereals copper ranged from 1.14 to 11.68 mg/kg and zinc from 7.20 to 72.07 mg/kg. Table I.

Opis:
Methodical questions of monitoring of water status in soil, cereals grain and wood are discused ( where monitoring is understood as registration of time and spatial variability of selected properties). Amount of viariables which is necessary in order to determine water status depends on the complexion of the considered phenomena and is, so far, the matter of arbitrary choice. In most practical cases the water status is expressed only by moisture of the considered material ( like the building timber). In practical terms, two variables suffice to express water status in cereal grain: moisture and temperature. To describe water status in the soil not less then five variables are needed: amount of water (the soil moisture) soil water potential, salinity, oxygenation and temperature. The only sensors that can be integrated in modern data acquisition system must be read electrically. Therefore electroresistance and electrocapacitance methods were considered. Dielectric sensors were recognized as the proper choice.Soil is a complex material having instable characteristics. For this reason it is the most difficult task to monitor soil water status, particularly to determine the soil moisture. Therefore it has been assumed that measuring methods verified for the soil will be also suitable for other, less complex materials. Thus, monitoring of soil water status was mainly discussed. Special attention was focused to the time domain reflectometry, TDR, as the semi selective method for the soil moisture and salinity determination.

Opis:
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.

Opis:
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.

Opis:
The present investigations aimed at determining the effect of various organic materials, i.e. farmyard manure (FYM), organic tannery sludge and compost of such sludge and peat on lead, copper and nickel fractions content in soil. Doses of peat compost and organic sludge were calculated according to the nitrogen amount per a FYM dose. After four years of experiment, fractions of Pb, Cu and Ni compounds were assessed in the soil from individual plots using the Zeien and Brummer's sequence chemical extraction method. Heavy metal contents were determined using a ICP-AES in JY 238 Ultrace apparatus. Lead accumulated mainly in the form bound with organic matter and with amorphic iron oxides. This metal distribution reveals its slight share in the mobile and exchangeable forms. Composts and sludge introduced into the soil did not affect any significant changes of the individual lead forms share as compared to FYM and NPK treated plots and the control. Some amount of copper occurred as mobile forms in all the soils. In the soil of all the treated plots, copper occurred mainly bound with organic matter and amorphic iron oxides. The basic share of nickel was found in the residual fraction bound with internal crystalline nets of initial elements. Beside the residual form, nickel was connected mainly with organic matter.

Opis:
The subject of the paper was to determine chromium and cadmium fractions in the soils treated with tannery organic materials. Methods, characteristics of experimental materials and the tested soils were presented in the first part of the paper. After four years of investigations soil samples were collected for the assessment of the total content of chromium and cadmium and their fractions. Results of a sequential chemical extraction confirmed literature data on the weak mobility of this metal in the soil. After application of the studied fertilisers, the share of the most mobile Cr fractions was slight. Iron oxides and residual fractions were most important for chromium accumulation. Cadmium mobility in the soil and its easy uptake by plants is related to a considerable share of mobile forms. A large share of mobile form was noticed in the analysed soils (54.5-68.3%). Exchangeable fraction bound smaller amounts of cadmium (6.8-13.2%). Similar amounts of cadmium were accumulated in the fractions bound to manganese oxides (8.5-19.6%). Organic matter did not contribute to this element binding and the amounts of cadmium stored in this fraction were 2.3-6.6%. Only very small amount of cadmium was accumulated in the form bound with the initial minerals.

The paper presents distribution of zinc, manganese and iron in fractions of soil treated with tannery sludge and compost of tannery sludge and peat, and, for the sake of comparison, the soil from a plot treated with farmyard manure (FYM), and mineral fertilisers. Total soil contents of zinc ranged from 38.0 to 47.3 mg kg-1 of soil. The share of mobile zinc forms ranged between 6.05-7.93%. Percentage of the exchangeable form was between 5.8-7.5% of the total Zn contents, while the share of forms bound with organic matter ranged between 10.7 and 12.7%. A considerable part of zinc was bound with manganese and iron oxides. Between 30.14- 43.72% of Zn were found in the residual form. Organic and mineral treatment influenced the share of easily soluble manganese compounds. It ranged between 15.6-19.7%. The least of manganese (1.0-2.0%) occurred in the compounds with crystalline iron oxides. The exchangeable form constituted between 3.4-4.2%, organic fraction accumulated slightly more. Manganese oxides retained the most of the element. Trace amounts of iron were revealed in the first three fractions. The biggest part of this metal was found in sparingly soluble compounds, mainly oxides (over 40%) and on residual fraction (over 30%).

Na podstawie wyników badań scharakteryzowano zjawisko strat spłukiwanego materiału glebowego w zależności od okresu badań (zimowego i jesiennego) oraz zwrócono uwagę na wymywanie makroelementów (P, K, Mg), odczyn i zawartość węgla organicznego w traconej w ten sposób glebie. Wyniki metody eksperymentalnej porównano z wynikami otrzymanymi metodą USLE.
The study on flushed soil material, its texture and chemical composition was carried out in the years 2003-2004 on experimental fields in two villages situated in Kłodzko Basin. The loss of flushed soil material was related to inclination of the area, to study period (winter and autumn) and to the type of plant cover and crop direction. Special attention was paid to the flushing of macroelements (P, K, Mg), soil reaction and organic carbon content in lost soil. The results of experimental method were compared with those obtained with the USLE method.
