Improvements in understanding how climate change may influence chemical and physical processes in soils, how this may affect nutrient availability, and how plants may respond to changed availability of nutrients will influence crop breeding programmes. The effects of increased atmospheric CO2 and warmer temperatures, both individually and combined, on soil microbial activity, including mycorrhizas and N-fixing organisms, are evaluated, together with their implications for nutrient availability. Potential changes to plant growth, and the combined effects of soil and plant changes on nutrient uptake, are discussed. The organization of research on the efficient use of macro- and micronutrients by crops under climate change conditions is outlined, including analysis of QTLs for nutrient efficiency. Suggestions for how the information gained can be used in plant breeding programmes are given.
对气候变化可能如何影响土壤中的化学和物理过程、这将如何影响养分的可利用性以及植物可能如何响应养分可利用性的变化的理解的提高将影响作物育种计划。评估了大气 CO2 增加和温度升高（单独和组合）对土壤微生物活性（包括菌根和固氮生物）的影响，以及它们对养分可利用性的影响。讨论了植物生长的潜在变化，以及土壤和植物变化对养分吸收的综合影响。概述了在气候变化条件下作物有效利用大量营养元素和微量营养元素的研究组织，包括对养分效率 QTL 的分析。提出了如何在植物育种计划中利用所获得的信息的建议。
