Cartographic support of the geoinformation system of agroecological assessment of agricultural lands
Bibliographic record
Abstract
A series of maps of agroecological typology of lands has been developed. A series of morphometric maps has been developed for geomorphological analysis of land use conditions, including maps of terrain elevation, slope steepness, vertical and horizontal dissection. The farm has a hilly relief with elevations ranging from 178 to 252 m with predominant slopes of 1.5–5°. Vertical dissection varies within 15–89 m, the density of horizontal dissection varies from 0.5 to 2.9 km/km2. Based on the digital version of the soil map at a scale of 1:10 000, maps of soil property indicators have been created, including physical clay (PC) content, soil waterlogging, and the degree of erosion. More than half of the land use area is represented by soils with a FG content of 40–50 %, slightly less common are soils of medium loamy composition with a FG content of 30–40 %, their share is 34 %. About 25 % of the land use area is subject to erosion, including weak and moderate erosion, another 24 % is excessively moistened. Analysis of geomorphological factors made it possible to identify five agroecological groups of lands, among which the most widespread is the semi-hydromorphic-erosive group (48 % of the area). This group occupies an altitudinal tier of 190–220 m with slopes of relief surfaces of more than 2°. The soil cover is characterized by the participation of slightly and moderately eroded sod-podzolic and sod-brown soils with slightly gleyic and gleyic, as well as washed soils. The share of eroded soils is 28 %, waterlogged—6 %. Intensive use of lands of this group is possible in special anti-erosion farming systems with the use of hydraulic engineering, forest and other meliorations. The erosion group of lands occupies an altitudinal tier of 220 m with a relief surface steepness exceeding 2°. The area of this group is 1 158 ha (24 %). This group is characterized by a contrasting soil cover, in which slightly and moderately eroded soils participate significantly—35 %, the share of semi-hydromorphic soils does not exceed 2.5 %. Differences in yield on various components of erosion structures can be smoothed out only with a high level of fertilizer application. Intensive use is possible subject to restrictions in the structure of arable land and the use of anti-erosion measures. Semi-hydromorphic-subordinate and hydromorphic-floodplain groups of lands occupy areas of 716 ha (15 %) and 559 ha (12 %), respectively. The soil cover of the hydromorphic-floodplain group includes alluvial and marshy soils. Such lands require special approaches when used.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
