“…The data obtained confirm the well-established opinion that the preference of crops and varieties for individual landscape positions has a pronounced biological and genetic specificity [13,20,25]. According to Ivanov, et al [34], perennial grasses (meadow timothy grass) prefer warmer elevated elements, while legumes (meadow and hybrid clover) prefer lower and cool elements of the agrolandscape. At the same time, due to the extreme instability of the weather and climate factor, such confinement cannot be stable [33,34].…”

“…According to Ivanov, et al [34], perennial grasses (meadow timothy grass) prefer warmer elevated elements, while legumes (meadow and hybrid clover) prefer lower and cool elements of the agrolandscape. At the same time, due to the extreme instability of the weather and climate factor, such confinement cannot be stable [33,34]. This is convincingly proved by the results of this study on perennial grasses under normal (in 2017 and 2019) and dry (in 2016 and 2018) moisture regimes.…”

“…The obvious lack of field experimental data in this direction was pointed out earlier [28]. The rather contradictory nature of the available assessments of the responsiveness of individual grain crops [29][30][31] and perennial grasses [32][33][34] to the specifics of landscape-ecological and agrochemical conditions complicates the problem.…”

The purpose of a comprehensive field experiment was to evaluate the agronomic efficiency of a precise organomineral fertilizer system based on a uniform and differentiated application of mineral and organic fertilizers. The methodological basis of the study was a two-factor landscape field experiment with grain-grass crop rotation, established within the sloping agricultural landscape of a gently undulating glaciolacustrine plain. It was determined, that soil and agrochemical conditions and a stable soil water regime were of decisive importance in the effectiveness of fertilizers within the agrolandscape. The level increase in yield from the differentiated application of peat-dung compost (once in a bare fallow) and mineral fertilizers relative to the uniform application was 7–12% for winter wheat, 5–11% for oats, 3–8% for perennial grasses, and in the entire crop rotation—5–8%. It regularly decreased during the mineralization of the applied organic fertilizers. Among the three variants of the precise fertilization system studied, the best result was achieved in the option, where organic and mineral fertilizers were applied differentially. In this case, the absolute increase in crop rotation productivity relative to the unfertilized variant reached 16.39 t ha−1 of cereal units or 116%, and relative to the uniform fertilizer system—2.27 t ha−1 of cereal units or 8%.
