However, without extensive field surveys, achieving timely, large-scale, high-resolution crop identification remains challenging. This study proposes an intelligent crop identification strategy (ICIS) that integrates crop phenological development information with a model transfer strategy based on machine learning, generating 10-meter resolution crop distribution maps of major crop types from 2020 to 2023 in Northeast China (NE). ICIS utilizes time series data from Sentinel-1 (S1) and Sentinel-2 (S2) to extract multi-source temporal features covering the full growth cycles of maize, rice, and soybeans. A Random Forest (RF) classifier was trained on representative sample sites, and model transfer was employed to predict crop distribution across different years and regions. The experimental results show that the models achieved F1-scores above 0.92 across provinces, peaking at 0.97. For rice, the F1-scores for Jilin, Heilongjiang, and Liaoning remained stable at 0.94. Maize F1-scores consistently exceeded 0.92, and although the soybean accuracy varied spatially, it reached 0.97 in certain areas. Comparison with crop area statistics from the China Statistical Yearbook at the city level revealed that the average root mean square error (RMSE) across four years for the three crops was 8.6 × 10<sup>4</sup> ha, with coefficients of determination (R<sup>2</sup>) consistently above 0.90, reaching up to 0.96. These results demonstrated the strong generalizability and robustness of the proposed ICIS Strategy for crop mapping across both temporal and spatial scales. Moreover, this study reveals the complementary strengths and key contributions of optical and Synthetic Aperture Radar (SAR) time series features in modeling crop growth dynamics. Overall, the ICIS provides an efficient and reliable technical means for the rapidly acquiring large-scale crop information. It provides robust support for agricultural monitoring and food security assessment, demonstrates significant potential for large-scale agricultural applications, and offers valuable insights and technical support for remote sensing data processing, image analysis, and machine learning-based agricultural automation and decision-making.</div></div>","PeriodicalId":53443,"journal":{"name":"Information Processing in Agriculture","volume":"13 2","pages":"Pages 283-302"},"PeriodicalIF":7.4,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148060320","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, there are no clear recommendations to optimize its production, perhaps due to its strict regulation. In order to optimize the management of the crop, the present work analyzes the effect of irrigation doses and planting density on the growth, production, and quality of the Kompolti variety of hemp, with an irrigation dose equal to the total water requirements of the plant and two deficit treatments, corresponding to 75 and 50 % of these requirements, and two planting densities, 7.0 and 3.1 plants m<sup>−2</sup>. For this, a multi-criteria analysis was performed that proposes the use of the Ordered Weighted Averaging (OWA) operator combined with the CRiteria Importance Through Inter-criteria Correlation (CRITIC) to obtain the weights, where the correlation is obtained as a function of the Pearson-OWA, to determine the aggregation of the quadratic differences by assigning different levels of importance as a function of their size. This application allows for the objective estimation of the weights starting with the attitudinal character of the decisor and its integration to the TOPSIS method. The strength of the innovation proposal has been evaluated, demonstrating that it does not exhibit a rank reversal phenomenon. Furthermore, the resulting ranking has been compared with those obtained using direct assignment methods, such as TOPSIS itself, Multicriteria Optimization and Compromise Solution (VIKOR), and Simple Additive Weighting (SAW), revealing minimal differences. This allows us to regard the proposed method as a generalization of these approaches. In the conditions utilized, the irrigation dose had a greater effect on growth, production, and the content of long fibers, rather than the planting density. In turn, planting density had a greater influence on the cannabidiol (CBD) content as compared to the irrigation dose. The classification obtained was led by the treatments with a higher planting density. Among them, the decrease in the irrigation dose worsened the assessment of the treatments. However, when the planting dose is low, a moderate water deficit improves the results with respect to the complete irrigation treatment or with intense deficit irrigation.</div></div>","PeriodicalId":53443,"journal":{"name":"Information Processing in Agriculture","volume":"13 2","pages":"Pages 253-262"},"PeriodicalIF":7.4,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148060317","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Data mining algorithms have demonstrated significant potential in inorganic nitrogen prediction. This review provides a systematic examination of data mining algorithms applied to inorganic nitrogen prediction for aquatic environments, focusing on the complete modeling pipeline from data preparation to predictive algorithm deployment. Essential data preparation techniques involving data acquisition, data cleaning, dimensionality reduction, and dataset partitioning are described in detail. Then, the mechanisms, techniques, and applications are critically evaluated according to the following five categories of data mining algorithms: machine learning models, deep learning models, tree-based models, fuzzy neural networks, and hybrid models. FNN and deep learning models yield top-tier accuracy (mean R<sup>2</sup> &gt; 0.90). In addition, hybrid models integrating LSTM have emerged as the most promising and prevalent framework, driving advancements in prediction precision. Despite significant progress, the field continues to face challenges such as insufficient data quality, limited model generalizability, and a lack of interpretability. Integrating multimodal data, developing lightweight real-time prediction systems, combining explainable artificial intelligence with physics-informed constraints, and strengthening uncertainty quantification will strongly advance inorganic nitrogen prediction models toward more accurate, reliable, and practical decision-support tools. This review provides a systematic reference for researchers and practitioners.</div></div>","PeriodicalId":53443,"journal":{"name":"Information Processing in Agriculture","volume":"13 2","pages":"Pages 318-342"},"PeriodicalIF":7.4,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148060321","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
