The experiment was carried out on chernozem during 2020-2021 in Dolj County, the wheat variety used is Glosa, an early autumn wheat, resistant to drought. The experiment was placed in the field according to the block method, in 4 repetitions with 8 variants. Following the use of different doses of fertilizers, the dynamics of nitric nitrogen, mobile phosphorus and mobile potassium in the soil, in the plant and in the grains were monitored at 3 determination dates, as well as the production obtained. After the analyzes carried out, it was found that the soil is rich in nitric nitrogen, ammoniacal nitrogen, the plants having at their disposal the nitrogen necessary for nutrition, and as regards the content of P and K, the soil is well supplied with these elements. Following the dynamics, the decrease in the content of main macroelements was observed, the younger the plants, the richer they are in these elements, and as the vegetative growth phase ends, the content decreases.
