This research study assessed the use of Pueraria phaseoloides crops as cover in oil palm (Elaeis guineensis) plantations to improve the ecological function of soils under tropical conditions. The plots examined (90 palms•ha -1 ) were established 5, 7, 11, and 30 years ago. The results showed a high and stable specific coverage index that ranged between 52 and 87%. This enhanced soil moisture by reducing the incidence of solar radiation. It also increased competitive capacity with the complex of weeds present and improved soil nutrient averages (1.60 mg/L N and 0.42 mg/L P). Fruit bunch average yields also improved in the short term, ranging from 10.6 to 22.4 t•ha -1 , with more frequent harvest events when compared to the control. It is concluded that Pueraria phaseoloides is a sustainable alternative to improve the establishment of plantations under tropical conditions.

“…A meta‐analysis concluded that green manures significantly improved the succeeding grain yield, and the increasing rates of leguminous and nonluminous green manures were correspondingly more than 12.6% and 7.9%, respectively (Fan et al., 2021; Liang et al., 2022; Ma et al., 2021). This study showed that leguminous HV and cruciferous OV increased maize grain yield by 25.6% and 13.8%, respectively, when compared to Fallow.…”

Green manures (GM) combined with fertilizer reduction is an efficient measure to alleviate the environmental issues caused by the overapplication of chemical fertilizer. However, both the environmental and economic benefits remain unclear in coastal regions that are affected by both soil salinization and climate change. A field experiment was conducted in low‐yield cropland in the Yellow River Delta to explore the effects of green manure rotation combined with fertilizer reduction on the soil environment and economic sustainability. Two GM species, Vicia villosa (HV) and Orychophragmus violaceus (OV), a traditional winter wheat (Wheat), were grown in winter, with a fallow control (Fallow). In the subsequent maize season, three fertilizer rate treatments, a full rate of 600 kg ha−1 compound fertilizer (F100), 85% of the full rate (F85), and 70% of the full rate (F70), were applied in each former treatment. The results indicated that GM return markedly increased soil total N (TN) and P (TP) before the V6 stage of maize (when maize had 6 leaves). The average TN contents of HV and OV increased by 56.9% and 38.5%, respectively, compared with that of Wheat, while the values for TP were 13.6% and 16.9%. Compared with Fallow, the maize yields of HV and OV increased by 25.6% and 13.8%, respectively, while that of Wheat decreased by 9.1%. The average partial fertilizer productivities (PFPs) for HV and OV increased by 25.3% and 14.0% compared with Fallow, while Wheat decreased by 8.9%. The PFPs for F85 and F70 increased by 19.4% and 37.7%, respectively, compared with F100. Reducing the fertilizer rate to 70% in the HV–maize rotation pattern did not reduce but increased the total net profit and rate of return. Thus, HV–maize rotation combined with 30% fertilizer reduction is suggested for sustainable agriculture in this region.

“…As one of the four biggest continuous Mollisol zones, the soil quality in Northeast China is threatened by SOM deterioration and soil erosion resulting from intensive cultivation (Liu et al, 2010; Yan et al, 2011). Considering the relatively high NUE but also the vulnerability to agricultural management in Northeast China, there is a need to improve the sustainability of the cropping system by implementing conservative strategies such as cover cropping, residue return, and no‐till practices (Ding et al, 2006; Fan et al, 2021; Pittelkow et al, 2015).…”

Northeast and East China account for ~36% of the Chinese rice cultivation area, yet considerable spatial disparities in nitrogen use efficiency (NUE) exist between these regions. The underlying causes remain poorly understood. Herein, we conducted a case study in two sample sites from two regions, Wuchang and Changshu, using multi‐scale evidence chains spanning macro‐ and micro‐ processes to identify the determinants of spatial NUE variability. Field studies showed higher NUE (partial factor productivity, PFP, and agronomic efficiency, AE) but lower ammonia volatilisation in Wuchang paddy soil. By separating edaphic factors from climatic conditions, soil replacement pot studies between Wuchang and Changshu revealed that both apparent (AE and recovery efficiency, RE) and 15N‐traced NUE were higher, whereas 15N fertilizer losses were lower in Wuchang‐soil than Changshu‐soil irrespective of site, suggesting soil type contributed to differences in soil N retention capacity and NUE of the soils. Process‐scale results showed that greater rates of gross N mineralizsation (13‐fold higher), gross nitrification (93% higher), and denitrification (52% higher) in Changshu‐soil compared to Wuchang‐soil corresponded to functional gene relative abundance, signifying larger reactive N losses and reduced soil N retention capacity. Microbial community analysis suggested that the differential N transformations were caused by differences in ammonia‐oxidizing archaea (AOA) family nitrososphaeraceae and Nitrospira‐like nitrite‐oxidizing bacteria (NOB). This highlights the importance of specific efficiency‐enhanced strategies tailored to the edaphic characteristics of cropping regions, such as increasing soil N retention capacity using enhanced‐efficiency fertilizer in East China, while implementing conservation management strategies in Northeast China. Highlights Field‐scale studies revealed higher NUE and lower NH3 volatilisation in Wuchang site. Soil replacement pot studies showed higher NUE in Wuchang‐soil regardless of sites. Process‐scale results unravelled high N losses and low soil N retention in Changshu‐soil. Varying NUE partially correlated with Nitrososphaeraceae AOA and Nitrospira‐like NOB.
