The paper reflects the results of the effectiveness of the use of various doses of mineral fertilizers in a long stationary experiment on spring soft wheat for nine rotations of a six-field crop rotation (27 years of cultivation) in the conditions of the steppe zone of the Volga region. The systematic use of medium and high doses of nitrogen-phosphorus fertilizers contributed to obtaining the highest yield increases to control in the experiment throughout the entire research period. The average level of correlation between hydrothermal conditions in the period May-July and crop productivity has been established. Separate calculations by month showed an average level of correlation with June. Based on the results of regression analysis, the degree of influence of hydrothermal conditions as a factorial feature on the productivity of spring soft wheat in the experiment was determined. The analysis showed that the effect of the obtained values of the hydrothermal coefficient in May and July on the production process of vegetating plants was insignificant, and in June it reached 30% according to experience.

The research was carried out on southern chernozems in arid conditions of the Orenburg Urals in 2002-2021. The influence of agrometeorological conditions of the growing season, spring reserves of soil moisture and nutrients, cellulolytic activity of microorganisms, content of organic matter, humus and acidity in the soil after applying mineral fertilizers on increasing productivity of millet (Panicum miliaceum L.) cv. Orenburg 9 were studied. The soil and millet crops were selected as the object of research. The work uses field, thermastatic-weight, ionometric, Machigin, application-weight, Tyurin, dispersion and statistical methods of research. Field experiments were performed in four-field, two-field crop rotations and continuous cropping according to the following scheme: 1) Sowing after durum wheat in the aftereffect of black fallow (control); 2) Sowing after common wheat in the aftereffect of black fallow; 3) Sowing after common wheat in the aftereffect of soil-protective fallow; 4) Sowing after common wheat in the aftereffect of sideral fallow; 5) Sowing after durum wheat; 6) Millet continuous cropping. It was revealed that the studied factors in the experiment increased millet productivity under two-field crop rotation with durum wheat after fertilizers application. Compared to the control, the maximum increase of grain yield was after using ammophos complex fertilizer (N40P40) - by 0.45 tons; feed units - 0.44; energy units - 0.26 and feed protein units - 0.24 t/ha. The best effect on increasing productivity was provided by: July precipitation - 28.05 %, spring reserves of productive moisture in 0-30 cm soil layer -- 25.96 %; in 0-100 cm - 20.86 %, nitrate content - 71.80 %, phosphorus - 38.05 %, potassium - 33.07 %, microbial activity (cellulose decomposition) - 62.32 % (p 0.05) compared to the control. The highest organic matter content (17.6 %) and humus (3.5 %) in soil and neutral acidity (pH = 7.0) create favorable conditions for growing millet after durum wheat. As a result of research on other crops, it was found that these factors do not affect yield increase. Positive results of the influence of factors can be useful in increasing millet productivity.

In the conditions of a long stationary experiment conducted in the Saratov region on the Southern Chernozem, it was found that for eight rotations of a six-field grain-pair crop rotation (48 years) in the variant without fertilization, carbon losses from the 0-40 cm layer were the highest. Fertilizers N32P16K7 and N38P13K8 per 1 ha of crop rotation area reduced its losses by 29-32%. When applying N54P17K7, an increase in the migration of organic carbon into the underlying layer of 40-100 cm was noted. The total nitrogen content in the control decreased by 8.7% compared to the initial data. The introduction of N15P13K8 and N38P13K8 per 1 ha of crop rotation area contributed to the preservation of nitrogen compounds in the humus layer of the soil. The content of total phosphorus in both non-fertilized and fertilized soil has changed slightly over 48 years of research. Systematic application of fertilizers led to an increase in the fraction of calcium phosphates.
