Microplastics (MPs) pollution has caused a threat to soil ecosystem diversity and functioning globally. Recently, an increasing number of studies have reported effects MPs on ecosystems. However, these mainly focused bacterial communities few limited functional genes, which is why ecosystems are still not fully understood. Fertilization treatment often coinsides with exposure in practice. Here, we studied environmentally relevant concentration polyethylene properties, microbial communities, functions under different types fertilization history. Our results showed that 0.2% PE could affect pH, but this effect varied according type Long-term history alter fungal diverse farmland (P < 0.05). Soil more sensitive than exposure. greater impact the lower genes abundance increases pathogenic microorganisms. These findings provided integrated picture aid our understanding histories.

Meta-analysis on how manure application changes soil organic carbon storage

Abstract Manure application to agricultural soils is widely considered as a source of nutrients and method maintaining levels soil organic carbon (SOC) mitigate climate change. At present, it still unclear which factors are responsible for the SOC stock dynamics. Therefore, we analyzed relationship between changes site characteristics, properties, experiment characteristics manure characteristics. Overall, included 101 studies with total 592 treatments. On average, on increased stocks by 35.4%, corresponding 10.7 Mg ha −1 . applications in conventional tillage systems led higher (+ 2.2 ) than under reduced tillage. Soil increase upon was non-tropical conditions 2.7 compared sub-tropical climate. Larger increases after were achieved intermediate shallow topsoils (in 0–15 cm 9.5 16–20 13.6 ), but also deeper (> 20 4.6 regardless intensity.

Soil Organic Carbon Sequestration after Biochar Application: A Global Meta-Analysis

Agronomy, Journal Year: 2021, Volume and Issue: 11(12), P. 2474 - 2474

Published: Dec. 5, 2021

Biochar application to soil has the potential sequester carbon in long term because of its high stability and large-scale production potential. However, biochar technologies are still relatively new, global factors affecting long-term fate environment poorly understood. To fill this important research gap, a meta-analysis was conducted including 64 studies with 736 individual treatments. Field experiments covered experimental durations between 1 10 years amounts 100 Mg ha−1. They showed mean increase organic (SOC) stocks by 13.0 ha−1 on average, corresponding 29%. Pot incubation ranged 1278 days 5 g kg−1 200 kg−1. raised SOC 6.3 75%. More accumulated >500 pot 6–10 field than shorter durations. Organic fertilizer co-applications significantly further increased SOC. from plant material higher C sequestration fecal matter, due C/N ratio. increases after were medium fine grain textured soils coarse sizes.

Carbon for soils, not soils for carbon

Abstract The role of soil organic carbon (SOC) sequestration as a ‘win‐win’ solution to both climate change and food insecurity receives an increasing promotion. opportunity may be too good missed! Yet the tremendous complexity two issues at stake calls for detailed nuanced examination any potential solution, no matter how appealing. Here, we critically re‐examine benefits global SOC strategies on mitigation production. While estimated contributions vary, almost none take saturation into account. show that including in estimations decreases contribution by 53%–81% towards 2100. In addition, reviewing more than 21 meta‐analyses, found observed yield effects are inconsistent, ranging from negative neutral positive. We find promise win‐win outcome is confirmed only when specific land management practices applied under conditions. Therefore, argue existing knowledge base does not justify current trend set agendas focusing first foremost sequestration. Away climate‐smart soils , need shift soil‐smart agriculture adaptative adapted each local context, where multiple functions quantified concurrently. Only such comprehensive assessments will allow synergies sustainability maximised agronomic requirements security fulfilled. This implies moving away targets agricultural soils. occur along this pathway contribute should regarded co‐benefit.

Microbial necromass in cropland soils: A global meta‐analysis of management effects

Abstract Microbial necromass is a large and persistent component of soil organic carbon (SOC), especially under croplands. The effects cropland management on microbial accumulation its contribution to SOC have been measured in individual studies but not yet summarized the global scale. We conducted meta‐analysis 481‐paired measurements from soils examine identify optimal conditions for accumulation. Nitrogen fertilization increased total C by 12%, cover crops 14%, no or reduced tillage (NT/RT) 20%, manure 21%, straw amendment 21%. was independent biochar addition. NT/RT fungal more than bacterial necromass. Manure higher fungal, leading decreased ratio fungal‐to‐bacterial Greater increases after amendments were common semi‐arid cool climates with pH <8, proportional amount input. In contrast, mainly warm humid climates. application irrespective properties climate. Management strong when applied during medium (3–10 years) long (10+ periods larger initial contents, absent sandy soils. Close positive links between biomass, indicate important role stabilized products accrual. increment (accumulation efficiency) NT/RT, crops, ranged 45% 52%, which 9%–16% N fertilization. summary, long‐term enhancing accumulation, optimizing sequestration requires site‐specific management.

An increase in nitrogen (N) recovery efficiency, also denoted as N use efficiency (NUEr), is crucial to reconcile food production and environmental health. This study assessed the effects of nutrient, crop soil management on NUEr accounting for its dependency site conditions, including mean annual temperature precipitation, organic carbon, clay pH, by meta-regression models using 2436 pairs observations from 407 primary studies. Nutrient increased 3.6-11%, 4.4-8%, while reduction tillage had no significant impact. Site conditions strongly affected induced changes NUEr, highlighting their relevance site-specific practices. Data driven showed that global can 30%, current average 48% 78%, optimal combinations nutrient (27%), (6.6%) (0.6%) management. will most cases allow with acceptable losses water.
