In this study, we developed machine learning-based biomass prediction models using two advanced gradient-boosted tree algorithms, CatBoost and XGBoost. A comprehensive dataset comprising cereal rye biomass and management information from 24 U.S. states, combined with soil and weather data, were used to train the models. Models relying solely on early spring weather inputs achieved moderate predictive skill (R2 ≈ 0.74). Incorporating later-season weather data modestly improved mid-season fits but led to overfitting in late-spring predictions. Extending CatBoost to quantile regression enabled estimation of 10%–90% prediction intervals with moderate pinball loss. Overall, our findings demonstrate that publicly available soil and weather data, supplemented with limited management inputs, can support interpretable, uncertainty-aware biomass predictions suitable for optimal cover crop management.","PeriodicalId":48502,"journal":{"name":"Agricultural & Environmental Letters","volume":"11 1","pages":""},"PeriodicalIF":3.6,"publicationDate":"2026-01-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://acsess.onlinelibrary.wiley.com/doi/epdf/10.1002/ael2.70055","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145963947","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We evaluated nematode counts as a potentially rapid measure of land use effects on soil biology in a benchmark Mollisol. We assessed pedons (0–120 cm) from conventional, no-till, and grassland fields in eastern North Dakota in October 2022. Although bulk density was 25% higher at 5–10 cm and aggregate stability was 36% lower (0–5 and 5–10 cm) in conventional versus grassland fields, land use did not affect nematode counts above 20 cm (288–2498 100 g−1 dry soil). Land use did mitigate nematode responses to soil properties. Nematodes more than doubled with increasing aggregate stability in no-till and grassland samples and were reduced by a third with increasing bulk density in grassland samples. Although nematode counts per se are not useful for assessing land use effects, soil properties can be used to predict nematode numbers in the series.","PeriodicalId":48502,"journal":{"name":"Agricultural & Environmental Letters","volume":"11 1","pages":""},"PeriodicalIF":3.6,"publicationDate":"2026-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://acsess.onlinelibrary.wiley.com/doi/epdf/10.1002/ael2.70052","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145969699","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
