Abstract
<p><strong>Background</strong>: Soil erosion is a natural process accelerated by anthropogenic activities such as agriculture, leading to increased runoff and erosion, resulting in global environmental and economic losses. Addressing this issue through conservation agriculture is critical, particularly in arid regions where soil degradation is prevalent. This study adds value by evaluating the combined effects of tillage practices and antecedent soil moisture conditions (AMC) on runoff and soil erosion under controlled rainfall simulation. <strong>Objective</strong>: To assess the effects of tillage practices and AMC on runoff and soil erosion, hypothesizing that conservation-oriented practices would reduce erosion and runoff. <strong>Methodology</strong>: A randomized complete block design experiment was conducted in an arid zone of North-central Mexico. Four tillage treatments were evaluated: 1) no crop (NC), 2) maize with conventional tillage and crop residues (CTR), 3) maize with conventional tillage (CT), and 4) maize sown by handspike (HS). Each treatment was tested under two AMC scenarios: dry and wet. Runoff and soil erosion were measured, and results were analyzed using ANOVA. <strong>Results</strong>: Dry AMC significantly reduced erosion in HS (p ≤ 0.01) and CTR (p ≤ 0.05) compared to wet AMC. CT and CTR produced the lowest erosion under wet AMC (p ≤ 0.05). For total runoff, CTR and HS produced the lowest values under dry AMC. These findings highlight the effectiveness of crop residue cover in CTR and no-tillage cropping (HS) in reducing both erosion and runoff. <strong>Implications</strong>: The study demonstrates the importance of soil moisture conditions and tillage practices in managing erosion. Limitations include the use of simulated rainfall, which may not fully capture natural variability. However, the findings provide valuable insights for conservation agriculture in arid regions. <strong>Conclusion</strong>: Crop residue cover and no-tillage cropping are effective in reducing soil erosion and runoff, especially under dry AMC. These practices are crucial for sustainable soil management in arid agroecosystems.</p>

Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
