Abstract

fetched live from OpenAlex

Wind-driven soil erosion is a major environmental issue that can lead to decreased soil productivity by eroding nutrient-rich fine soil particles away from agricultural lands. Many Manitoba soybean fields are routinely rolled shortly after planting. There are concerns that the practice of land rolling in soybean production may increase the potential for wind erosion through breakdown of soil aggregates into smaller unstable aggregates and reducing the roughness of the soil surface. Therefore, an experiment was conducted as an on-farm trial in eight different locations in in the Red River Valley of southern Manitoba during 2018 and 2019. The experimental trials were established with two treatments (rolled and non-rolled) arranged using a randomized complete block design. Sediment traps, specially designed and fabricated for this study, were used to collect wind-eroded sediment moving over the soil surface along the length of each treatment. The results of this study did not show that land rolling increased wind erosion risk by reducing soil surface roughness. With respect to the experimental evidence on amount of sediment collected by wind erosion samplers, the results show that there is a significant difference among samplers with collection opening at 5cm and 20cm, which indicates that most of the particles transported at 5 cm height. Detailed particle size distribution showed, the wind-eroded particles collected by the sediment traps with collection openings at 20 cm were slightly finer than the traps with openings at 5cm.

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
