Lack of information about effective CC management and the costs and benefits of CCs may contribute to low adoption. We use CC management data from 112 farms in the Soil Health Partnership network (2015–2021) to characterize CC management practices and costs. Soil Health Partnership farmers spent a median of US$98.84 per hectare to plant CCs on trial fields in the 2021 crop year, and costs varied with management practices. Farmers also experimented with CC management practices; more than half of 100 farmers providing panel data used more than one seeding method, and the share “planting green” increased over time. This diversity of CC management practices, heterogeneity in costs (and benefits), and experimentation process—among other factors—may make it challenging for farmers to develop expectations about whether CCs will be profitable on their farm in the short, medium, or long-run.</p>","PeriodicalId":48502,"journal":{"name":"Agricultural & Environmental Letters","volume":null,"pages":null},"PeriodicalIF":2.6,"publicationDate":"2022-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://acsess.onlinelibrary.wiley.com/doi/epdf/10.1002/ael2.20070","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42480360","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}

The primary contention of this commentary is that data sharing requirements will make on-farm research increasingly difficult while also not achieving the stated purposes of opening data.

Moreover, de-identified farm geospatial data will have greatly reduced reusability. Limited guidance is available on appropriate mechanisms for sharing of farm geospatial data.
