Abstract : A microclimate is defined as the climate of the surface layer of the air and of the soil, i.e., a climate differing considerably from general climatic conditions in a given geographic zone or area. A microclimate forms as the result of the influence of dissimilar active surfaces within a zone or area on the attendant meteorological elements, either individually or in combination with each other. All these climatogenetic factors change rather rapidly either naturally or artificially by biotic interferences. Accordingly, also micrometeorological conditions caused by these factors (illumination, temperature, humidity, wind, et cetera) change. Therefore, in distinction from a macroclimate, it is usually customary to speak of a microclimate over brief intervals of time in any one year or portion of a year. On the basis of relief types, slope orientations, soil types, including their indigenous plants, a fairly accurate concept of the microclimate was developed, and on the basis of the complex of these factors, the land use of arable areas was determined. In this manner, the most suitable plots for field plants, orchards, vineyards, vegetable and melon fields have been classified. (Author)
