Improved soil management is increasingly pursued to ensure food security for the world's rising global population, with ancillary benefit of storing carbon in soils lower threat climate change. While all increments organic matter are laudable, we suggest caution ascribing large, potential change mitigation enhanced management. We find that most promising techniques, including applications biochar and silicate weathering, collectively not likely balance more than 5% annual emissions CO2 from fossil fuel combustion.

Abstract Drylands (hyperarid, arid, semiarid, and dry subhumid ecosystems) cover almost half of Earth’s land surface are highly vulnerable to environmental pressures.

Aridity limits plant production results poorly developed soils, with coarse texture, low C:N C:P, scarce organic matter, high vulnerability erosion.

Due unbalanced distribution global large regional differences, urbanization expansion causes important areas face more serious arable land resource shortages.

Abstract Forests constitute important ecosystems in the global carbon cycle. However, how trees and environmental conditions interact to determine amount of organic stored forest soils is a hotly debated subject. In particular, tree species influence soil (SOC) remains unclear. Based on compilation data, we show that functional traits standing biomass explain half local variability SOC. The effects SOC depended climatic with strongest effect observed under boreal climate acidic, poor, coarse-textured soils. Mixing forests also favours storage SOC, provided over-yielding occurs mixed forests. We propose sink can be optimised by (i) increasing biomass, (ii) richness, (iii) choosing composition based according conditions.

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.
