“…Geographic Information System software tools have been used in several studies to create the spatial variables needed to predict agricultural production [46][47][48][49][50][51][52][53]. Some researchers chose to use the ArcGIS software 10.7.2, which we also used in this study, whereas others used an open-source GIS software variant, such as QGIS [54,55].…”

This research study presents the spatio-temporal distribution of the main agricultural crops in Romania using a modern digitalisation technique, namely interactive GIS mapping. Interactive GIS mapping includes various features specific to the development of sustainable Romanian agriculture, including the arable area of Romania, information on the area (hectares) cultivated with corn, wheat, sunflower, and rape during the 1990–2018 period, the degree of mechanisation, the number of tractors, and information regarding the landforms, a natural factor in relation to cultivated surfaces. Agricultural land should be properly used based on its ability to meet the demands of consumers of traditional Romanian products with an ecological label, but also the needs of the local population, and, at the same time, to ensure the sustainability of the natural environment through the practice of ecological agriculture. The purpose of this research is to provide an overview of the current state of the main agricultural crops in Romania. From a theoretical but also practical point of view, this research presents, for the first time, a retrospective analysis of each county in Romania in terms of the geospatial distribution of major agricultural crops using interactive GIS mapping. Geospatial data were processed in ArcGIS Geographic Information System 10.7.2. The results of this study show that the most extensive cereal areas at the county level in Romania are corn and wheat. The largest areas cultivated with corn and wheat in 2018 were recorded in the Western Plain, the Romanian Plain, and the Moldavian Plateau. For wheat, increases were also recorded in the Dobrogea Plateau. The intensification of labour productivity and the promotion of the sustainability of the natural environment in Romania is presented through the main indicator (the number of tractors) of the degree of mechanisation of agriculture. The higher values of this indicator are in the counties of Bihor, Timiș, and Maramureș. Limitations in Romania’s agricultural data present substantial challenges to the sector’s development and sustainability. Addressing these challenges is essential for informed decision making, policy formulation, and effective resource allocation.

Applying different types of fertilizers to different depths of soil according to demand is advantageous in that it can optimize the distribution of nutrients in arable soil, adjust the nutrient supply of each growth stage of wheat, and increase grain yield. In the study, a layered fertilization opener that could realize the layered fertilization was developed. The interaction model between the opener, fertilizer and soil was established using EDEM simulation software. A response surface analysis was used to determine the optimal parameters of the opener. Specifically, the horizontal distance between the fertilizer drop openings was 140 mm, the machine speed was 1.05 m/s, and the angle of the opener was 37°. Furthermore, field experiments demonstrated that the average depth of upper layer was 8.39 cm, the average depth of middle layer was 16.465 cm, the average depth of lower layer was 24.025 cm, the average spacing of upper layer was 8.075 cm, and the average spacing of lower layer was 7.6 cm. The corresponding findings demonstrated that the layering effect of the opener met the requirements of the fertilization standard.

In this paper, a vertical rotary tillage with fixed-layer fertilizer performance was designed, the design process was introduced. And the fertilization performance was verified by Edem software simulation. The final field test shown that the average tillage depth could reach 26.8cm; the fertilizer layer was concentrated under the soil surface 45-48mm; the width of the fertilizer layer was 238-240mm; the thickness of the fertilizer layer was 223-226mm, which satisfied the design requirements.
