. The grading of agricultural land is a complete operation of in-depth knowledge of the conditions for growing and developing plants and of determining the degree of favourability of these conditions for each use and cultivation. Agricultural production, and especially plant production, directly influenced by environmental factors and conditions in continuous stability, and to varying degrees of relation to man’s intention and decision to change it, is a decisive factor in the economic development of society. Naturally, the manifestation of each climate attribute is determined by the geographical position of the place analysed, especially from a latitudinal point of view. These two elements determine, together with exposition, the ratio of the earth’s surface to the sun and, implicitly, the way of receiving heat and, to a good extent, the manifestation of atmospheric precipitation. The geological and, last but not least, lithological complexity of our country’s territory has made soils evolve on extremely varied rocks and parental materials, from ultra-basic to acidic rocks, from clays to sands, from rich and complex rocks, in geochemical aspect, to poor materials. Soil conditions, i.e., soil as a repository of vegetation, water, and food elements, represent a complex of attributes that act directly and indirectly on the growth and fruiting of plants. The potential and ecological capacity of an area of land to ensure plant development and yield is called fertility. Soil fertility, in accordance with climate factors, allows the reaching o agricultural parameters specific to each crop.
