The K use efficiency is higher in potatoes, with the maximum potential up to 55%, compared to cereals at 19%. Potatoes require high quantities of K, especially in well-drained sandy soils, to maximise growth and yield. Because K is a highly leaching-prone nutrient in these soils, its deficiencies could affect plant health, metabolism (K is required to activate more than 60 enzymes) and productivity. Optimal potato growth necessitates maintaining 1.8% K in the tubers, corresponding to a need of 0.22 kg K₂O ac⁻¹ for a substantial yield. The review article highlights the significant use of potash fertilisers in the United States, with an average consumption of 4.43 million metric tons between 2010 and 2021, underscoring the importance of K in agricultural practices. The paper also highlights the difference in K requirement and removal among different potato varieties that require the maximum amount in processing types. This manuscript discusses K's management schemes through soil testing, plant tissue analysis and artificial intelligence. The integration of various machine-learning methods could offer promising prospects for predicting K response in potatoes, aiming to improve nutrient management and sustainable crop production.

Wall was a pioneering scientist, a trailblazer, a mentor for many, and the strongest advocate of soil biodiversity. Her research impacted many aspects of soil ecology, and she was best known for her work in Antarctic McMurdo Dry Valleys, soil invertebrates, ecosystem services and effects of climate change. Her research and advocacy had transformational impacts both on the fundamental understanding on distributions, functions they provide, and the need for assessment and conservation of soil biodiversity (van der Putten et al., <span>2023</span>). Her tireless efforts and strongest possible advocacy of soil biodiversity was the foundation of changes we saw in recent years in global policies, including recently adopted agreement to include soil biodiversity in national biodiversity reporting at COP-15 of the Convention of Biological Diversity (CBD) in Montreal, Canada 2022 (The Kunming-Montreal Global Biodiversity Framework, <span>2022</span>). Her scientific contributions have been recognised by many prestigious awards and fellowships including being elected as a member of the National Academy of Science and American Academy of Arts and Sciences.

Up to 95% of our food come from soils (World Economic Forum, <span>2023</span>). Sadly, one-third of these soils are already under some type of degradation.

However, this awareness was not always there, and soils and their biodiversity were poorly understood and largely underestimated.

The historical stability of winegrowing methods has spanned almost 3000 years since the introduction of viticulture in Europe. However, in the last 70 years, the wine sector in the Europe has experienced substantial transformations. These changes are attributed to the widespread adoption of mechanisation and industralisation in the 1950s and the establishment of the Common Agricultural Policy (CAP). The growing concern for the environment and climate change in the European Union (EU) has significantly influenced the successive reforms of the CAP. These reforms have resulted in the acquisition of new commitments to protect the environment, mitigate climate change and reduce biodiversity loss over the years. In this work, we carried out a critical analysis of the most relevant aspects of the new CAP and address the regulatory framework of organic agriculture in the EU as a tool for improving the sustainability of vineyards. Currently, Spain is the country with the largest vineyard area in the world, reaching 964,000 hectares. This represents 13% of the world's vineyards and 30% in the EU, which demonstrates the importance of this crop in Europe. Due to its relevance, we focused our critical analyses of the new CAP on Spain as a case study. The latest reform of the CAP, applicable for the period 2023-2027, is the most ambitious in environmental terms and includes instruments such as reinforced conditionality, eco-schemes and payments for agri-environment–climate commitments. Finally, we propose that by integrating concepts and management strategies from current organic and regenerative viticulture together with historical strategies derived from treatises and classic authors across a wide range of societies and cultures, the goals of the new CAP can be successfully met.

Due to climatic constraints and heat stress condition, the potentiality of wheat to eradicate existing hunger and malnutrition has been severely limited all around the world.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Materials and Methods</h3>\u0000 \u0000 <p>To evaluate the performance and stability of elite wheat genotype under irrigated and heat stress environment, a field experiment was conducted during the wheat growing season of 2020, 2021 and 2022 under irrigated and heat stress environment that altogether created six distinct wheat growing environments.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Results</h3>\u0000 \u0000 <p>The combined ANOVA revealed that all quantitative traits studied were significantly influenced by heat stress environments (<i>p</i> &lt; 0.01). Which Won Where (WWW) model revealed, Bhairahawa lines (BL) 4407, Nepal lines (NL) 1384 and NL 1346 performed best under irrigated environments of 2020, 2021 and 2022 while BL 4407, NL 1384 and NL 1381 performed best under heat stress environment of 2020, 2021 and 2022. WWW model showed, NL 1369, NL 1386 and NL 1376 as the most stable genotypes across irrigated and heat stress environment. The phenotypic correlation, path analysis, network diagram, cluster analysis and cluster based principal component analysis analysis revealed traits, days to booting (DTB), plant height (Ph), spike length (SL), ten spike weight (TSW) and thousand kernel weight (TKW) are most closely associated with grain yield of wheat.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusion</h3>\u0000 \u0000 <p>High yielding genotypes should be selected based on earliness in DTB, longer Ph, SL and higher TSW and TKW under both environments. Breeding for taller genotypes should specifically be focused to obtain high yielding genotypes under heat stress environments.</p>\u0000 </section>\u0000 </div>","PeriodicalId":100834,"journal":{"name":"Journal of Sustainable Agriculture and Environment","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/sae2.12098","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140114228","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
