Getting to know the natural conditions and the technological features for a certain crop presents a special economic and social importance, both for the big agricultural exploitation and for the small producer. Relations of a varied and complex reciprocity are established between the properties of the soil and the main technological elements, fact shown by the level of wheat yields in the period 2016-2019, on a typical Chernozem soil, slightly gleyic, epicalcaric, medium clay loam/medium clay loam from Lovrin, Timis County. Regarding these considerations, the paper presents several aspects regarding the role and the physical-geographical characteristics of nitrogen and phosphorus fertilizers on the wheat production, based on studies with the theme "Research on pedoclimatic and anthropogenic factors that condition land productivity from the Low Plain of Banat” carried out during the doctoral school, respectively from September 28, 2016 and until now. The research consists of the accumulation of scientific data regarding the evolution of some components of agricultural land productivity, related to the cosmic-atmospheric and telluric-edaphic supply, necessary to substantiate current crop technologies for their efficient use through a thorough knowledge. Thus, the paper presents the results regarding the influence of nitrogen and phosphorus fertilizers on the wheat production in the agricultural period 2016-2019, in the physical-geographical and climatic-edaphic conditions from the Low Plain of Banat. Taking into account these aspects regarding the existence of risks, due to various manifestations of natural factors and irrational human interventions, in this paper we tried to transfer the descriptive theoretical activities to analytical ones that lead to practical solutions related to the sustainable management of edaphic resources. The research is in line with the substantiation of sustainable agriculture systems, responding to the requirements of establishing the scientific database necessary to substantiate some technologies and the elaboration of integrated agroecosystem management measures. The importance of this paper derives from the fact that the soil/land properties are differentiated in the territory, both by the variation of the pedogenesis factors and conditions, and by the fact that in the plant production system the productive potential of the soil intersects with the human effort. Hence, we can talk about a cultural technically-economically conditioned productivity, a result of the contribution of soil, climatic factors, human labour, investments with water and fertilizers, quality seed, all vitally integrated by plants in the biomass production.
