Abstract. Resilient, productive soils are necessary to sustainably intensify agriculture increase yields while minimizing environmental harm. To conserve and regenerate soils, the need maintain build soil organic matter (SOM) has received considerable attention. Although SOM is considered key health, its relationship with yield contested because of local-scale differences in climate, farming systems. There a quantify this set general framework for how management could potentially contribute goals sustainable intensification. We developed quantitative model exploring relates crop potential maize wheat light co-varying factors management, type, climate. found that these two crops on average greater higher concentrations SOC (soil carbon). However, increases level off at ∼2 % SOC. Nevertheless, approximately two-thirds world's cultivated lands currently have contents less than 2 %.

Responses of soil carbon sequestration to climate‐smart agriculture practices: A meta‐analysis

Global Change Biology, Journal Year: 2019, Volume and Issue: 25(8), P. 2591 - 2606

Published: April 19, 2019

Abstract Climate‐smart agriculture (CSA) management practices (e.g., conservation tillage, cover crops, and biochar applications) have been widely adopted to enhance soil organic carbon (SOC) sequestration reduce greenhouse gas emissions while ensuring crop productivity. However, current measurements regarding the influences of CSA on SOC diverge widely, making it difficult derive conclusions about individual combined effects bringing large uncertainties in quantifying potential agricultural sector mitigate climate change. We conducted a meta‐analysis 3,049 paired from 417 peer‐reviewed articles examine three common as well environmental controlling factors. found that, average, applications represented most effective approach for increasing content (39%), followed by crops (6%) tillage (5%). Further analysis suggested that were more pronounced areas with relatively warmer climates or lower nitrogen fertilizer inputs. Our demonstrated through adopting practices, cropland could be an improved sink. also highlight importance considering local factors conditions their combination other practices) identifying appropriate mitigating

Biochar effects on phosphorus availability in agricultural soils: A meta-analysis

Scientific Reports, Journal Year: 2019, Volume and Issue: 9(1)

Published: June 27, 2019

Abstract Phosphorus (P) is a limiting nutrient for plants and an essential element all life on Earth. As the resources of phosphate rock are depleting, new management tools environmentally friendly P fertilizers needed. In order to achieve this, recent studies have proposed use biochar, carbon-rich solid product thermochemical conversion biomass with minimal or zero oxygen supply, as slow-release fertilizer. However, effects biochar plant-available in soils been reported be variable. Therefore, we quantitatively evaluated existing peer-reviewed data using meta-analysis draw general conclusions. present study, 108 pairwise comparisons their response application availability soils. Our results indicate that can act short-, mid-, long-term fertilizer its effect depending feedstock, pyrolysis temperature amount. Overall, addition significantly increased agricultural soil by factor 4.6 (95% confidence interval 3.4–5.9), independent used feedstock production.
