Abstract
Water is basic element in agriculture, and along with the soil characteristics, it remains the essential for the growth and evolution of plants. Trends of air temperature and precipitation for Slovenia indicate the increase of the air temperature and reduction of precipitation during the vegetation period, which will have a substantial impact on rural economy in Slovenia. The impact of climate change will be substantial for soil the water balance. Distinctive drought periods in past years had great impact on rural plants in light soils. Climate change will most probably also result in drought in soils which otherwise provide optimal water supply for plants. Water balance in the cross section of the rooting depth is significant for the agriculture. Mathematical models enable smaller amount of measurements in a certain area by means of measurements carried out only in characteristic points serving for verification and calibration of the model. Combination of on site measurements and mathematical modelling proved to be an efficient method for understanding of processes in nature. Climate scenarios made for the estimation of the impact of climate change are based on the general circulation models. A study based on a hundred year set of monthly data showed that

Climate scenarios made for the estimation of the impact of climate change are based on the general circulation models. A study based on a hundred year set of monthly data showed that in Slovenia temperature would increase at min. by 2.3{sup o} C, and by 5.6{sup o}C at max and by 4.5{sup o}C in average. Valid methodology for the estimate of the impact of climate change applies the model using a basic set of data for a thirty year period (1961-1990) and a changed set of climate input parameters on one hand, and, on the other, a comparison of output results of the model. Estimating climate change impact on irrigation demand for West Slovenia for peaches and nectarines grown on Cambisols and Fluvisols was made using computer model SWAP. SWAP is a precise and power too[ for the estimation of elements of soil water balance at the level of cross section of the monitored and studied profile from the soil surface to the contact with under-soil water. The change of data was initiated by disparity of 1.5{sup o}C with the basic set of data for daily air temperature being increased by 1.5{sup o}C, 3{sup o}C and 4.5{sup o}C. Precipitation estimate took into consideration anticipated seasonal changes. Several scenarios were studied, the first one with daily precipitation quantities decreased by 10% throughout the whole year and the second one, i.e. mixed scenario with precipitation in the period April- September decreased by 10%1 and in the period October-March increased by 10%. Results indicated that the increase of air temperature had a greater impact on the calculation of irrigation needs than the reduction of precipitation. Comparison of soil depth to the number of days that water shortage (50% FC) appeared showed the smallest occurrence in deep soils. It has been shown that due to the different water retention capacities water shortage on some soil types will be more expressed than on the others. This statement has been clearly confirmed on Cambisols and fluvisols. (Author)}
