Opis:: Badanie nad wykorzystaniem filtru glebowego do oczyszczania wód powiekowych zostały przeprowadzone na poletkach doświadczalnych z udziałem roślin w pobliżu oczyszczalni ścieków Hajdów koło Lublina. Pomiary rozkładu stężeń form azotu takich jak: NH4+, N03", N02‘ na wejściu ścieków oraz na różnych głębokościach filtru glebowego zostały przeprowadzone w czasie, po zastosowaniu nawodnień. Równolegle prowadzono pomiary stanu oksydoredukcyjnego gleby (Eh), na stałe zamontowanymi elektrodami. Praca zawiera wyniki zmian form azotu w roztworze glebowym w czasie nawodnień w funkcji Eh gleby, wykazując dodatnią korelację z azotanami (V) i ujemną z azotanami (III)
Nitrate transformation in a soil (Eutric Histosol) irrigated with municipal waste waters after II step treatment. Investigations of efficiency of utilisation of soil as a waste water filter were performed on experimental fields (Eutric Histosol) with different plants located near waste water treatment plant at Hajdów near Lublin. Measurements of distribution profiles of such minerał nitrogen forms as N03> N02‘, and NH4+ were performed during and after periods of flood irrigation. Simultaneously distribution patterns of redox potential were recorded with permanently installed platinum electrodes. The changes of particular nitrogen forms on the background of redox potential distribution are presented and discussed. A negative correlation of N02‘ and a positive of N03' with redox potential was found.

Opis:: W pracy przedstawiono fizyczny model zjawisk przenoszenia wody, soli i ciepła w glebie. W modelu uwzględnia się: wielofazowy transport wody w warunkach nieizotermicznych, przenoszenie nie reagującej i nieadsorbującej substancji chemicznej oraz przepływ ciepła.
In this work we are developing a physical model of water, salt and heat transport in soil medium. In this model we are taking into consideration multiphase transport of water in nonisotermal conditions. Flow of non-reactive and non- adsorbing substance, and heat flow is decribed also.

Opis:: This paper presents the aim and realization procedures of the project EURO- ACCESS (Agroclimatic Change and European Soil Suitability, No. EV5VCT920129, CIPA3510PL923399, CIPDCT930022, CIPDCT925058, financed by EC). The project was coordinated by Dr. Peter Loveland, Soil Survey and Land Research Centre. Crarifield University, Silsoe Campus, Bedford, Great Britain. The project was conducted in 1992-1995 by scientific institutes from 6 countries, including the Institute of Agrophysics, Polish Academy of Sciences in Lublin. This book consists of main information about the whole project and detailed information about, tasks performed by the Institute of Agrophysics, PAS in cooperation with the Institute of Soil Science and Plant Cultivation (IUNG) Puławy as well as with other European institutes. There are presented results of investigations conducted in cooperation with ADAS Land Centre, Gleadthorpe Research Centre, Meden Vale, Mansfield, Great Britain, (Chapt. 2: Modelling of water movement in the soil profile with the preferential flow influence.), Maria Curie-Sklodowska University, Lublin, Poland (Chapter 3: The method of rainfall intensity estimation for runoff prediction), INRA Montpellier, Prance and IUNG Puławy, Poland (Chapter 4: Verification of yield prediction model using soil and climatic data). The basic task of EURO-ACCESSS project was the model and program development for prediction of climate change influence onto potential yield of important crops. The climatic and physiological properties are assumed to be known. In hydrological submodel developed in ADAS, Mansfield, there was Richards one dimensional flow model assumed. In order to include heterogeneity of the soil the submodel of bypass flow was created by IA PAS and included into existing one dimensional flow procedure. The horizontal infiltration submodel is based on Green- Ampt simplified flow model. It plays role of source and/or sink term within the Richards procedure and accounts for the bypass flow of water from the surface to the deeper layers of the soil profile. The model has been verified in the laboratory conditions, on the basis of numerical experiments and in the field condition. Laboratory flow experiment with induced cracks shows the possibility of explanation of bypass flow with developed procedure. Numerical experiment shows ade- quateness of proposed crack and inaeropore description to the field data. The model allows easily estimate macropore parameters from the simple measurements at the soil surface or from the profile cross-section. The calibration of the model on the basis of measured data consisting soil moistures at different depths and precipitation data, soil hydraulic properties and évapotranspiration data, shows better agreement with the bypass flow model included. The main problem was to estimate momentary rain intensity from the daily precipitation data available. This was done using the statistical model of the rain intensity distribution. The momentary rain intensity plays major role in the runoff estimation. On the basis of long term (1982-1993) historical precipitation, climatic and yield data collected in IUNG Puławy, the whole EURO-ACCESS II has been verified. The plant submodel based on EPIC model was modified and suited to European conditions by INRA, Montpellier. The whole verification was conducted on the basis of daily climatic data. The error analysis shows that, during 1985-1990 period when model was calibrated estimated yield error was 22,5%-, for the period 1984 and 1991 1993 where model was verified the yield error was 8.0%. For the whole period of simulation the error was 15.3%.
