In this study, we focus on one of those drivers, that is, climate similarities. We estimate statistical models to quantify the potential influence of 16 climate variables on varietal similarities across countries, as well as on how their varietal mixes have become more or less similar since 2000. The results indicate not only that countries with more similar climates have more similar varietal mixes but also that in recent years countries with more similar climates have become even more similar in their mixes.

However, multiple methods are used for measuring aggregate stability, making it difficult to compare results and limiting universal interpretations in soil health assessment frameworks like Soil Health Assessment Protocol and Evaluation. We cross-correlated three common water-stable aggregate methods (WSA_CASH, WSA_ARS, and WSA_SLAKES) using a dataset of nearly 1400 samples and developed pedotransfer functions using random forest models to evaluate method performance. We found that the WSA_ARS and WSA_CASH methods can be reasonably cross correlated through pedotransfer functions because they use similar processes for estimating aggregate strength. Conversely, the WSA_ARS and WSA_SLAKES methods are not transferable. We suggest that the WSA_ARS aggregate stability method is the most established and best reference method for use in soil health analysis frameworks.

Similarly, deciding the regulations governing organic and conventional production does not fall within the pursuit of science. Rather, science should show how different management practices influence the environment. The regulatory framework of organic farming is derived from normative values rather than scientific principles, which now categorizes the production.</p><p>McGuire (<span>2017</span>) contend that ideology and science do not blend well. However, researchers inherently possess normative values, which shape their research interests and perspectives. It could be argued that this is only problematic when the goal of the scientific pursuit and ideology crosses, thus becoming activistic. This can harm the scientific process by drawing wrongful conclusions upon poorly constructed experiments, and thus the scientific process in general. All scientific decisions—for example., formulating a research question, designing the study, and analyzing the data—are conducted by humans, with values and experiences influencing their choices, therefore including some normative values (Reed, <span>2011</span>; Risjord, <span>2016</span>). While this is generally recognized by social sciences, natural sciences often neglect it.</p><p>Analysis of studies comparing the environmental impacts of organic and conventional farming show variation in environmental impact, as for dairy production (Cederberg &amp; Mattsson, <span>2000</span>; De Boer, <span>2003</span>; Kristensen et al., <span>2011</span>; Thomassen et al., <span>2008</span>). When assessing the two production regimes the production level between the systems is seemingly important. This is because emission or environmental impact are often divided upon the emission per produced product, which as an effect of production levels obtained is favoring higher production. Organic farming utilizes less resources per produced product, but often has a lower productivity. Organic farming, however, often claims other ideologic values besides production, such as health, ecology, fairness, and care (IFOAM, <span>2005</span>).</p><p>Comparison of organic and conventional management also raises the question of whether the production systems are similar enough to be comparable. Both organic and conventional production can be described with the goal to produce goods to sell, while somehow having different aims. Organic farming emphasizes different values, complicating direct statistical comparisons with conventional systems, since these values are not described with a reductionistic approach. The external values in organic production seem to have a cost, often resulting in lower productivity than conventional production.</p><p>The reasoning of McGuire (<span>2017</span>), who advocates that organic agriculture should change its ","PeriodicalId":48502,"journal":{"name":"Agricultural & Environmental Letters","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2024-08-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ael2.20139","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141991597","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}
