Background: Biological soil crusts (biocrusts) are commonly found in arid ecosystems and are known to have increased carbon (C) and nitrogen (N) concentrations compared to non‐crusted soil. Similar biocrusts were recently identified in Florida, USA sandy soil agroecosystems where they could impact soil biogeochemical cycling, particularly of C and N, in the crop rooting zone.

生物土壤结皮增强了沙质土壤农业生态系统上生根区的水分和养分

背景：生物土壤结皮（生物结皮）通常在干旱的生态系统中发现，与非结壳土壤相比，其碳（C）和氮（N）浓度增加。最近在美国佛罗里达州的沙质土壤农业生态系统中发现了类似的生物结皮，它们可能影响作物生根区的土壤生物地球化学循环，特别是碳和氮。
