Organic soils under grassland use are often highlighted in this regard. However, given that approximately two-thirds of Schleswig-Holstein's (SH's) (Northern Germany) agriculturally used area is classified as arable land, these large areas have a potential for additional carbon storage, too.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Aims</h3>\u0000 \u0000 <p>The aim is to determine the current SOC stocks of mineral arable soils in SH and derive additional carbon storage potentials based on these data to predict additional storage potentials for the main soil type groups and geological regions.

The additional SOC storage potential in the topsoil (30 cm) of the total area of 9.1 Mt SOC was calculated, that is, an average potential of 13 t SOC ha<sup>−1</sup>.

These differences are due to variations in climate and parent material (especially marshlands), as well as the inherent limitations of the median method, which is a robust but potentially underestimating approach.

Nevertheless, the nutrient use efficiency (NUE) is low, ranging from 10% to 55% across different crops for macronutrients with overfertilization of nutrients imposing environmental risks. There is a pressing need for better NUE for sustainable food production to meet the growing population's demand without impacting the environment. Enhanced efficiency fertilizers (EEFs) can potentially increase NUE and mitigate environmental risks by coupling their nutrient release with crop nutrient uptake. EEFs have gained significant recognition in agricultural research. This detailed review discusses the basics, classification, and benefits of EEFs worldwide in various crops, and the coating material and release mechanism of EEFs are discussed in extensive detail along with the application of EEFs with other best management practices. Additionally, the review outlines the challenges and considerations regarding EEFs that impact their adoption at a global scale and emphasizes the significance of investigating future strategies and directions, stressing the importance of a comprehensive approach to address research gaps and ways to unlock the full potential of EEFs for sustainable agriculture. The assessment underscores the efficacy of EEFs as an innovative solution to enhance NUE and mitigate environmental impacts related to fertilization.</p>\u0000 </div>","PeriodicalId":16802,"journal":{"name":"Journal of Plant Nutrition and Soil Science","volume":"188 4","pages":"570-584"},"PeriodicalIF":2.8,"publicationDate":"2025-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144782828","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
