Agricultural Systems, Journal Year: 2021, Volume and Issue: 194, P. 103251 - 103251

Published: Sept. 8, 2021

In the European Union (EU-27) and UK, animal farming generated annually more than 1.4 billion tonnes of manure during period 2016–2019. Of this, 90% is directly re-applied to soils as organic fertiliser. Manure promotes plant growth, provides nutritious food soil organisms, adds genetic functional diversity improves chemical physical properties. However, it can also cause pollution by introducing toxic elements (i.e., heavy metals, antibiotics, pathogens) contribute nutrient losses. Soil organisms play an essential role in transformation into degradation any potential constitutes; however, management practices often neglect biodiversity. this review, we explored impact from farmed animals on biodiversity considering factors that determine effects vice versa.

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.

Global variation in soil carbon sequestration potential through improved cropland management

Global Change Biology, Journal Year: 2021, Volume and Issue: 28(3), P. 1162 - 1177

Published: Nov. 2, 2021

Widespread adoption of improved cropland management measures is advocated to increase soil organic carbon (SOC) levels, thereby improving fertility and mitigating climate change. However, spatially explicit insight on impacts limited, which crucial for region-specific climate-smart practices. To overcome these limitations, we combined global meta-analytical results practices SOC sequestration with data current potential areas the measures. We included (a) fertilization practices, i.e., use fertilizer compared inorganic or no fertilizer, (b) tillage no-tillage relative high intermediate intensity tillage, (c) crop cover crops enhanced residue incorporation. show that estimated C varies between 0.44 0.68 Gt yr-1 , assuming maximum complementarity among all taken.

Organic farming, which is deeply rooted in traditional agricultural practices, has witnessed a profound evolution over the last century. Transitioning from grassroots initiative resisting industrialization of agriculture to global industry, organic farming now plays pivotal role addressing contemporary challenges related environmental health, sustainability, and food safety. Despite growing consumer demand for products market access, its challenges.

Abstract A central role for nature-based solution is to identify optimal management practices address environmental challenges, including carbon sequestration and biodiversity conservation. Inorganic fertilization increases plant aboveground biomass but often causes a tradeoff with diversity loss. It remains unclear, however, whether organic fertilization, as potential solution, could alter this by increasing without Here we compile data from 537 experiments on inorganic across grasslands croplands worldwide evaluate the responses of biomass, diversity, soil (SOC).

Responses of soil organic carbon stock to animal manure application: A new global synthesis integrating the impacts of agricultural managements and environmental conditions

Global Change Biology, Journal Year: 2021, Volume and Issue: 27(20), P. 5356 - 5367

Published: June 5, 2021

Enhancing soil organic carbon (SOC) through applying animal manure is of interest for both sustaining cereal production and mitigating greenhouse gas (GHG) emissions. Previous syntheses showed that manuring-induced SOC changes varied substantially with agricultural managements environmental conditions, while their significance relative importance to such variability are still largely uncertain. Here, we presented a new synthesis using an updated balanced database integrating the stock plausible explanatory factors in 250 observations at global 120 sites. Manure application increased by 7.41 ± 1.14 (95% confidence interval, CI) 8.96 1.83 Mg C ha-1 , respectively, compared mineral fertilized (REF-min) unfertilized (REF-zero) references. Of which approx. 72% 34% were directly contributed manure-C input, respectively. Following IPCC (Intergovernmental Panel on Climate Change) approach, these corresponded change 1.27 0.04 1.40 0.08 CI), Basing database, identified amount input as most important factor variations resultant changes. More importantly, our integrative analysis distinguished properties (e.g., pH initial content) regulating efficiency enhancing stock. These results indicate that, similar rate, could sequestrate much more alkaline soils than neutral acidic soils. By impacts findings would help develop region-specific tailor-made measures agriculture refine regional GHG inventories.
