Opis:: 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%).

Opis:: The effect of granulated organic waste material overgrown with Trichoderma atroviride TRS25 on the survival of Sclerotinia sclerotiorum and Chalara thielavioides in the soil was investigated. Application of this material into the soil at a dosage of 1% (w/v) reduced the survival of S. sclerotiorum sclerotia to almost zero after 2 months of incubation. The sclerotia were parasitized by T. atroviride fungus multiplied on granulates. The detrimental effect of granulates on Ch. thielavioides was observed after 4 months of incubation. The granulates, with Trichoderma and without the fungus, caused a decrease of the pathogen population in soil. Trichoderma atroviride introduced into the soil as a conidia suspension did not decrease the amount of Ch. thielavioides but the fungus parasitized S. sclerotiorum sclerotia. After the addition of granulated waste material, an increase of bacteria, especially the Pseudomonas group in the soil was observed.

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.

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:: Since potassium is essential for plant nutrition, should this element be deficient in sewage sludge used for plant fertilization supplementary mineral potassium fertilization is necessary. The aim of the present study has been to evaluate the effect of fertilization with organic materials on maize yield, its potassium concentrations and the content of bioavailable forms of potassium in soil of different grain size distribution. The impact of fertilization on potassium concentrations in maize was examined in a 3-year, two-factor pot experiment (the factors were soil and fertilization). The grain size distribution of the test soil material was weakly loamy sand (psg), sandy silt loam (gpp) and medium silt loam (goep). Sewage sludge originated from two different municipal mechanical and biological sewage treatment plants. Mixtures of sewage sludge with peat were prepared at a gravimetric ratio 1:1 converted to material dry matter. For chemical analyses the plant material was mineralized in a muffle furnace (at 450oC for 5 hrs) and the remains were dissolved in diluted nitric acid. Bioavailable potassium was determined with Egner-Riehm method in the soil material, which was dried and sifted through a 1mm mesh sieve. Potassium was determined by flame photometry in solutions of the plant material and soil extracts. Fertilization with sewage sludge and mixtures with peat had a more positive effect on maize yield than fertilization with mineral salts. In comparison with organic materials supplied to the soil, mineral salt treatment significantly increased potassium content in maize biomass. Mineral supplementation of potassium introduced with organic materials and its balancing did not increase soil abundance in bioavailable potassium in comparison with the initial abundance, although a diversified soil response to the applied fertilization was observed.
Biorąc pod uwagę niezbędność potasu w żywieniu roślin, deficytowa zawartość tego składnika w osadach ściekowych wykorzystywanych do nawożenia roślin wymaga jego uzupełnienia w formie mineralnej. Celem badań była ocena wpływu nawożenia materiałami organicznymi na plon części nadziemnych i korzeni kukurydzy, zawartości w nim potasu oraz zawartości form przyswajalnych tego składnika w glebach o różnym składzie granulometrycznym. Ocenę wpływu nawożenia na zawartość potasu w kukurydzy przeprowadzono w 3-letnim dwuczynnikowym doświadczeniu wazonowym (czynniki: gleba, nawożenie). Do badań użyto materiału glebowego o składzie granulometrycznym piasku słabo gliniastego (psg), gliny piaszczystej pylastej (gpp) i gliny średniej pylastej (gśp). Osady ściekowe pochodziły z dwóch różnych komunalnych oczyszczalni mechaniczno-biologicznych. Mieszani ny osadów ściekowych z torfem sporządzono w stosunku wagowym 1:1, w przeliczeniu na suchą masę materiałów. W celu oznaczenia potasu materiał roślinny mineralizowano w piecu muflowym (temp. 450 st.C, 5 h), pozostałość roztworzono w rozcieńczonym kwasie azotowym. W materiale glebowym wysuszonym i przesianym przez sito o średnicy oczek 1 mm potas przyswajalny oznaczono metodą Egnera-Riehma. W uzyskanych roztworach materiału roślinnego oraz ekstraktach glebowych potas oznaczono metodą fotometrii płomieniowej. Nawożenie osadami ściekowymi i mieszaninami osadów z torfem działało korzystniej na plony kukurydzy niż nawożenie solami mineralnymi. W porównaniu z zastosowanymi doglebowo materiałami organicznymi, nawożenie solami mineralnymi istotnie zwiększyło zawartość potasu w biomasie kukurydzy. Zrównoważenie solami mineralnymi ilości potasu wprowadzanego z materiałami organicznymi i jego zbilansowanie nie zwiększyło zasobności gleby w potas przyswajalny, w porównaniu z zasobnością wyjściową, chociaż zaobserwowano różne zmiany w glebach po zastosowanym nawożeniu.
