The key to restoring arid and semi-arid ecosystems is maintaining soil water organic carbon contents. Alfalfa ( Medicago sativa L.) a high-yield perennial forage crop performs ecological functions as drought-resistance leguminous herb. It has been widely planted for reconstruction of degraded soils in the Loess Plateau northwestern China, but long-term planting may affect carbon–water coupling lead yield reduction. To maximize benefits reconstructed grassland, this study explored couplings water, carbon, alfalfa productivity along chronosequence area Plateau. Space-for-time substitution approach was used select different-aged stands grassland (1, 5, 7, 10, 15, 20, 30 years old). above-ground biomass (AGB), storage (SWS), (SOCS), coordination degree D ) were measured 0–100 cm profile.

Introduction Alfalfa-grass binary mixtures outperformed monocultures in nutrient use, soil content, and biomass yield. Nonetheless, the impact of fertilization strategies on fungal community composition ecological functions legume-Grass remains under-researched. This study aimed to explore effects different distribution environmental characteristics. Methods A field experiment Gansu, China, has been conducted five strategies—no (CK), three partial methods (+PK, +NK, +NP), balanced (+NPK)—on population richness, composition, drivers. Rhizosphere soils from treatments were sampled investigated using high-throughput ITS sequencing. Results Compared CK, +NPK led higher capabilities ( P &lt; 0.05), organic matter (SOM), available nitrogen (AN), phosphorus (AP), potassium (AK) increased by an average 29.7 %, 42.3 101.2 24.3 respectively; alkaline phosphatase (APA), catalase (CAT), sucrase (SA) 56.6 31.8 46.7 microbial carbon (SMBC), (SMBN), (SMBP) 64.8 65.1 60.4 respectively. The dominant fungi rhizosphere Mortierellomycota Ascomycota, accounting for 82.2%-92.3%. species richness was highest +PK treatment. From NMDS RDA analysis, it can be discerned that SA, AK, CAT key factors influencing structure inter-root alfalfa; SOM awnless brome. Discussion Our findings optimal fertilizer strategy mixtures. provided a technical basis scientific application development local mixed grassland ecosystems.
