WATER, AIR AND SOIL REQUIREMENTS OF VEGETABLE PLANTS GROWN IN GREENHOUSES

Abstract

Vegetable culture was one of the first practical human activities. However, with the advent of society have been continuously developed the knowledge and methods of vegetable plants cultivation, with very rapid rate in the modern times, which led to the consolidation of vegetable as a science of its own, thus detaching from plant growing, to which he belonged. Knowing the Ecology of vegetable plants especially presents a practical importance, because it is the basis for establishing and conveyance of culture technology. Among the abiotic factors (climatic, geographic, orographic, edaphic) the greatest importance for the plants, on which depends the ecological optimum, are the climate (air and water regime) and soil composition. Geographic and orographic factors influence indirectly the agro ecosystems by varying climatic and edaphic factors.
