“…( 6): [exp (lnRR ++ )−1] × 100% . The frequency distribution of the effect sizes was fit to a Gaussian distribution function for vegetable yields to test the homogeneity of observations (Gurevitch and Hedges, 1999;Xiang et al, 2021). A chi-square test determined whether the heterogeneity Q total among the lnRR of changes in vegetable yield with organic fertilizer treatment significantly exceeded the expected sampling error (Hedges et al, 1999).…”

To better understand the responses of vegetable yields in a greenhouse system to organic fertilizer through a quantitative evaluation based on peer-reviewed journal articles and in consideration of environmental managerial factors. We conducted a meta-analysis of 453 paired observations from 68 peer-reviewed journal articles to assess the response of vegetable yields in greenhouse vegetable systems in China to organic fertilization. Compared with the control (no organic fertilizer), organic fertilization significantly increased the yields of vegetables by 44.11% on average. The response of vegetable yields to organic fertilizer tended to increase with the increasing experimental duration. Organic fertilizer application had the greatest potential for leafy vegetables (+76.44%), in loamy soils (+53.94%), at moderate organic fertilizer carbon input levels (+54.13%), and in soils with moderate initial soil total nitrogen levels (+50.89%). Aggregated boosted tree analysis indicated that organic fertilizer carbon inputs, vegetable type and experimental duration were the predominant factors that manipulated the response of vegetable yields to organic fertilizer application. The rational application of farmyard manure would be a promising strategy for increasing vegetable yields in greenhouse vegetable systems in China. Factoring in vegetable type, carbon and nitrogen inputs of organic fertilizer, and soil texture would benefit vegetable yields with the application of organic fertilizer.

“…Despite the large differences between N returned via litterfall, STN was similar across species. STN is most unlikely to be impacted by climatic factors compared to SOC (Xiang et al 2021). However, substantial N losses appear to be occurring especially in the soil under P. reticulata with greater canopy openness and tendency for higher soil temperatures.…”

“…The soil C 4derived C losses are decreasing at a slower rate under C. tomentosum than P. reticulata and H. courbaril in the topsoil layers even though the temperature and humidity were the same. It is supported by the PCA where the13 C soil and15 N soil arrows were more related to C. tomentosum.Indirectly related to climatic factors, larger canopy densities will have higher rainfall and light interception and hence low soil moisture content and soil temperatures, respectively(Liu et al 2018;Xiang et al 2021). The higher canopy openness in P. reticulata stand (Fig.6) could also justify the lower C 4 -derived C due to rapid decomposition rates.…”

Aims Atlantic Rainforest biome is one of the most threatened in the world by deforestation where afforestation programs are urgently needed. N-fixing species should be prioritized in re-establishing forest covers as they can enhance soil C and N and stimulate cycling of other nutrients. Yet, tropical ecosystems play a key role in global warming and remain underestimated in the global biogeochemical balances. We aimed to investigate the effects of tropical N-fixing species on soil C and N pools after pasture conversionMethods We selected: Plathymenia reticulata, Hymenaea courbaril, and Centrolobium tomentosum 27-year-old monospecific stands. We evaluated soil organic carbon (SOC), nitrogen (STN), and the natural abundance of 13C and 15N in the soil profile up to 100 cm depth. Results SOC was higher for P. reticulata, but an opposite pattern was observed when combining only soil layers up to 30 cm soil depth. Meanwhile, STN was similar across species and d15N values showed enrichment at intermediate soil layers indicating 14N gaseous loss. Most of the SOC originated from the planted trees rather than the former pasture, except beneath C. tomentosum where C4 derived C is decreasing at a slower rate. Conclusion This study presents novel insights in the understanding of tropical N-fixing species effects on soil C and N where specific-species traits appear to mediate SOC retention to the mineral soil rather than the N-fixing ability per se.

“…The challenge with direct measurement of changes in some soil properties especially SOC stock in the short-term of less than five years is that small changes in total SOC occur over a large background stock, making it difficult to detect within this timeframe (Smith, 2004;Lal, 2009). For example, changes in SOC stock associated with afforestation of former croplands have been shown to be significant after 30 years (Li et al, 2012;Bárcena et al, 2014) or at least 10 years (Deng et al, 2016;Chatterjee et al, 2018) with no changes detected below five years (Xiang et al, 2021). Farmers and other land managers may anticipate annual payments to sustain their land management efforts, hence, there is an urgent need to identify measures of SOC and structure that reflect both short-and long-term impacts of land restoration programmes.…”
