The location and definition in the terrestrial space of each part of land defined morphologically, genetically, altitudinal, etc. plays an important role in defining the conditions for plant growth and fruiting. This study includes an interpretation of the results of the analyses on the entire arable area (534.81 ha) data contained in the agrochemical sheets in the form of arithmetic mean values of the analyses of samples harvested in the field and respectively weighted means at the level of bodies as well as the division of the areas by interpretation limits. In general, the agrochemical plots overlap the cadastral ones. There are two cases when, due to essential differences between some agrochemical elements (fertilizer supply data), the division of two plots into two agrochemical plots was required. The lands on which the areas under study are located, respectively the two bodies, are located on soils that belong to the category of chernozems, phaeozems, preluvosoils and gleiosoils. As it results from the agrochemical sheets from the analyses of pH values encountered in the perimeter but also from the specialized literature, it is specified that the need for calcareous amendments on weakly acidic soils appears only in conditions in which the soils contain exchangeable forms of aluminum and manganese at toxic levels as well as in those in which the exchangeable forms of these elements can appear during the vegetation period of the crops. In the studied perimeters such environments are not encountered, consequently the application of calcareous amendments is not necessary.
