How are microorganisms and nutrient cycling in saline soils affected by soil matric potential?

旱地农业受到盐分和干旱的威胁，众所周知，盐分和干旱单独存在不仅会降低作物生长，还会降低微生物活动和养分循环，而微生物活动和养分循环对可持续性至关重要。随着我们的气候变得越来越干燥，有必要了解干旱和零星的夏季降雨事件将如何影响盐碱地中的微生物活动和养分循环。作为一个国际土壤生物学家团队，我们将研究盐分和土壤水分对微生物活动和养分循环的相互作用。研究结果将为盐碱地目前和未来的养分循环以及改良策略的益处提供深入的认识。

Dryland agriculture is threatened by salinity and drought, and it is well-known that individually, both can decrease not only crop growth but also microbial activity and nutrient cycling which are critical for sustainability. As our climate becomes drier, it is necessary to understand how microbial activity and nutrient cycling in saline soils will be affected by drought and sporadic summer rainfall events. As an international team of soil biologists, we will investigate the interactions between salinity and soil moisture on microbial activity and nutrient cycling. The results will provide insights into nutrient cycling in saline soils now and in the future and the benefit of amelioration strategies.
