    Opis:
    The paper presents an original method of calculating actual water resource in forest skeletal soils as a sum of two components: water resource in the fine earth fraction and water resource in the skeletal (grain size ≥ 2mm) fraction. A scientific justification for applied procedures was provided. Functional forms of empirical equations were developed to calculate water resource in soil skeletal fraction depending on the moisture content in the surrounding fine earth fractions. Examples of detailed description of these dependencies for the organic and mineral matter layers of the skeletal soil profile under the stands of the Beskid Śląski Mountains are given.

    Opis:
    Natural resources are the basis of all material goods which are of special importance for the life and development of mankind. Therefore, sustainable management of natural resources is of great importance for modern society. The concentrations of heavy metals in the soil such as: (Cu, Fe, Cd, Mn, Pb, and Zn), have a negative impact on the contamination of crops. Human activity should be developed on the basis of the principles of environmental sustainability to achieve economic and social prosperity and environmental protection as well as, improve the environment polluted by human activity. Natural resources must be preserved and regenerated. Moreover, well-being, environmental management and maintaining the purity of the environment in the future enable the production of safe food. Preservation of good quality water resources creates security and maintains soil quality. Recently, there has been a marked increase in awareness of natural resources, especially the preservation of water quality, soil, and their importance to our lives. The study included various methodologies, qualitative and quantitative analyses, and statistics.

    Opis:
    The paper presents the method of converting relative moisture of the ground layer in the soil profile into water resource expressed in the thickness of the water layer. The basis of conversion is the dimensionless degree of the soil moisture content. Water resources in soil profiles calculated by means of the proposed method can be compared and directly related to water balance components of forest habitats, among others, precipitation volume, interception, transpiration, evapotranspiration, as well as water outflow from a catchment. The paper provides a description and justification of procedures applied to non−skeletal soils in the profiles without free groundwater table and those with saturation zone.

    На базе информаций из агрометеорологических постов и метеорологических данных вегетационного периода (в 1980-1986 гг.) положительно отмечена пригодность метода Баца определения ресурсов воды в почве для оценки районов требующих орошения. Выделена часть Польши в полосе центральных районов с отрицательным балансом осадков и испарения.
    Adaptation possibilities of the Вас’s method of calculation of water content in soil for irrigation purposes were estimated. To this agrometeorological information from agricultural experiment stations and standard meteorological data were used (for growing season 1980-1986). On this bas is the area with negative difference between precipitations and evaporation in central part of Poland has been distinguished.

    Opis:
    The monograph concerns the method of radiation temperature measurements of natural meadow plants and application of these measurements for evaluation of water stress and evapotranspiration.The aim of this study was: 1. to investigate the influence of the water energy state (soil water content and soil water potential) on radiation temperature of plant cover in laboratory and lysimetric experiments 1. the comparison and verification of the models of actual and potential evapotranspiration calculation with the use of plant cover radiation temperature measurement; the realisation of this aim was performed in two stages, i.e. by evaluation and preliminary selection of the methods of évapotranspiration calculation basing on literature studies and by verification of some chosen methods in ly- simetric investigation of meadow plant cover; 2. the determination of plant water energetic status using the Crop Water Stres Index (CWSI) and its correlation with soil water potential in the soil and plants. In the monograph the role of water for plants development was described and the physical principles of mass, momentum and energy transport in the boundary layer of atmosphere were presented. The principle of infrared radiation registration with the use of thermographic systems was described as well as the factors influencing the measurement of canopy temperature. The review and analysis of the methods of actual and potential évapotranspiration evaluation were performed for selecting the method which was the subject of later verification. The investigation were performed on two maximally differentiated soils with natural meadow plant cover. The radiation temperature measurements were performed with the use of AGA 680 thermovision system (3-3,5μm) and the AGEMA 880 system (8-13μm). The radiation temperature difference between the investigated plant cover and the one in comfortable water condition is a good indicator of water stress of plants, which is determined by soil water potential, as a decisive physical factor of its accessibility for plants. The temperature difference regarding to water comfort conditions increases to 2°C when the value of soil water potential exceeds pF 3,7, which corresponds to the range of unavailable water for plants, having the maximal values of 7°C with pF 4,2, which corresponds to the plant wilting point. The actual évapotranspiration evaluation method was chosen, basing on the heat balance equation, in which radiation temperature of canopy surface is used for the determination of sensible heat flux. Two modifications of this method differing with the way of the aerodynamic resistance determination were the subject of verification. Basing on the lysimetric studies, the components of heat balance equation were analysed as well as the impact of the state of thermodynamic equilibrium in the atmosphere on the accuracy of sensible heat estimation and the utilisation of actual and potential évapotranspiration for crop water stress evaluation using of Crop Water Stress Index (CWSI).
