The technological process of seeding is very important in the production of cereals because seed germination, growth, yield and the qualitative parameters depend on the quality of seeding. Variable rate and variable depth precision seeding technology is relatively new and has many unanswered questions. The aim of this work was to investigate the influence of precision seeding of winter wheat according to a variable rate and variable depth on the grain yield, to evaluate different technological processes of seeding in terms of energy and environmental aspects, and to compare the obtained results with conventional seeding technology. Experimental research on growing winter wheat was carried out in 2021–2022. Precision seeding was performed using a variable rate seeding map generated from soil electrical conductivity data obtained by field surface scanning with the apparent soil electrical conductivity instrument EM-38 MK2 (Geonics Ltd, Canada). Three seeding technological processes were applied, the first variant was a uniform rate (URS, control), the second was a variable seeding rate (VRS), the third was a variable rate and variable depth (VRSD). Energy and environmental assessment were carried out using technological operations, fuel and material equivalents. The results of the experimental studies showed that the highest winter wheat grain yield (8744.08 kg·ha-1) was in the VRSD variant and it was about 6.5% higher compared to the conventional URS variant. The energy environmental analysis reported that the best energy and environmental efficiency results were achieved using the same VRSD technology, with the highest energy efficiency ratio (8.81) and the best GHG emission efficiency ratio (10.31), and the lowest environmental pollution per ton of winter wheat grain produced (56.24 kg CO2eq t-1).

“…Studies have found that rotation tillage in the winter wheat season was an important practice that enriched the microbial community structure and increased the soil enzyme activity, thus facilitating the conversion and accumulation of soil nutrients and improving crop yields [ 2 , 5 ]. Deep tillage to 30 cm increased total soil N content in the 0–40 cm soil layer and improved crop root distribution [ 6 ], further promoting crop water efficiency and grain production [ 7 ].…”

Optimum tillage practices can create a suitable soil environment, and they improve the soil nutrient status to ensure crop development and yield. In this study, we evaluated the influences of six tillage practices on soil nutrients and maize yields from 2017 to 2019 in fluvo-aquic soil in the North China Plain. The field experiment was carried out by a split design with rotary tillage (RT) and deep tillage (DT) in wheat season in the main plot and no-tillage (NT), subsoiling between the row (SBR), and subsoiling in the row (SIR) in maize season in the subplot. The results showed that the soil nutrient content was higher under the treatments with rotary tillage in the wheat season in the 0–20 cm soil layer, while in the 20–40 cm soil layer, the soil nutrient content was higher under the treatments with deep tillage in the wheat season. The integrated principal component scores indicated that the soil nutrients had improved in the second year. The ecosystem multifunctionality (EMF) index was higher with the treatments with rotary tillage in wheat season in the 0–20 cm soil layer, while it was the highest under DT-SIR at 20–40 cm. Correlation analysis showed that the soil EMF index correlated significantly (p < 0.05) with the soil nutrient content mainly in the 0–40 cm soil layer. The higher maize yield was under the treatments with deep tillage compared to that under the treatments with rotary tillage in the wheat season. The yield-increasing effect was higher under the treatments with subsoiling than those utilizing no-till in the maize season, with the highest average yield of 13,910 kg hm−2 in the DT-SIR during the three years. Maize yield was strongly correlated with nutrients in the subsoil layer. The higher yield stability was found under RT-NT. To sum up, during the three-year experiment, rotary tillage in the wheat season combined with subsoiling in the maize season improved the soil nutrient content and the EMF index in the 0–20 cm layer, while the combination of deep tillage in the wheat season and subsoiling in the maize season improved those indices in the 20–40 cm soil layer, and increased the maize yield, the best one was under DT-SIR.
