INVESTMENTS ON THE PHYSICO-CHEMICAL AND AGROCHEMICAL PROPERTIES OF THE SOIL IN THE RURAL AREA - NIHORENI VILLAGE, REPUBLIC OF MOLDOVA

Abstract

In order to determine the agroecological quality of arable land, it is necessary to analyse a whole set of agroecological functions, and in the end this set will be different for the conditions of each region, field and even of a small examined plot. For this, an analysis of the diagnostic indicators of these agroecological functions is carried out, including the integral and partial indicators of the biotic, chemical or physical parameters of the studied lands: humus content, biogenic elements (if necessary), soil composition and their structural state in general, the phytosanitary status of crops, etc. The relevance of the research foresees the approach and evaluation of the land fund, regarding the condition of the lands in the village of Nihoreni, which would imply a sustainable development of all the objects of the natural environment in the area. The optimization of the natural environment boils down to finding a balanced relationship between the exploitation of ecosystems (rational use of natural resources), their protection and improvement. Since the human agricultural activity in the locality is carried out within the limits of the natural formations – landscape, transformed in the process of use as an agricultural landscape, the latter become an object of protection at the moment. The purpose of the study consists in the agroecological substantiation of a set of measures for the protection of agricultural lands in the town of Nihoreni. For the development and adaptation of agricultural systems of an adaptive landscape, an adequate system of agroecological land evaluation is necessary. We note that it differs significantly from the traditional land evaluation system practiced in land management. The productivity of agricultural crops is determined by the degree to which the climatic conditions correspond to the biological characteristics of the crops and the agrotechnics of their cultivation. The highest yield is obtained with the maximum use of climatic resources by the plant. It was found that the agroecological assessment of crop yield conditions remains an important challenge facing agriculture both nationally and internationally.
