Biochar may contribute to climate change mitigation at negative cost by sequestering photosynthetically fixed carbon in soil while increasing crop yields. The magnitude of biochar's potential this regard will depend on yield benefits, which have not been well-characterized across different soils and biochars. Using data from 84 studies, we employ meta-analytical, missing data, semiparametric statistical methods explain heterogeneity responses soils, biochars, agricultural management factors,...
Abstract Pyrogenic organic matter ( PyOM ) is considered an important soil carbon (C) sink. However, there are evidences that its addition to may induce a priming effect PE thus influencing C abatement potential. The direction, the size and mechanisms responsible for induced far from being understood. We collected approximately 650 data points 18 studies analyse characteristics of by . database was divided between on native fresh matter. Most were short‐term incubation therefore projections...
Abstract. Pyrogenic carbon (PyC), the residue of an incomplete combustion biomass, is considered as a (C) sink due to its assumed stability in soil. PyC turnover time estimated using two modelling approaches, based on data from 16 published studies (n = 54) degradation, ranged decadal centennial scale, varying with initial biomass type, pyrolysis temperature, and incubation or field study. The average one-pool approach was 88 y, best estimate two-pool 3 y for fast-cycling pool 870...
Pyrogenic carbon (PyC) is considered one of the most stable components in soil and can represent more than 30% total organic (SOC). However, few estimates global PyC stock or distribution exist thus not included any cycle models, despite its potential major relevance for pool. To obtain a picture, we reviewed literature published content SOC data. We generated first database including 560 measurements from 55 studies. Despite limitations due to heterogeneous studied locations gaps database,...
Abstract Numerical models are crucial to understand and/or predict past and future soil organic carbon dynamics. For those aiming at prediction, validation is a critical step gain confidence in projections. With comprehensive review of ~250 models, we assess how validated depending on their objectives features, discuss predictive can be improved. We find lack independent using observed time series. Conducting such validations should priority improve the model reliability. Approximately 60%...
Summary The relative importance of different binding mechanisms and associated biological agents on aggregate stability is still unclear. aim this study was to evaluate the role various during decomposition cauliflower residues, wheat straw, cattle manure poultry woody compost. We measured stability, hot‐water extractable polysaccharide, C mineralization, fungal microbial biomass dynamics in an amended silt loam soil, under controlled conditions. Soil using three methods involving fast...
Biochar properties vary, and characterization of biochars is necessary for assessing their potential to sequester carbon improve soil functions. This study aimed at key surface agronomic relevance products from slow pyrolysis 250-800 °C, hydrothermal carbonization (HTC), flash carbonization. The further relating current indicators. results suggest that biochar chemical composition can be inferred volatile matter (VM) consistent corncob miscanthus feedstocks the three tested production...
A multi-season field trial was carried out to investigate the effect of amendment biochar, lime, ash and washed biochar on growth maize. degraded, strongly acidic Ultisol (pHKCl 3.60), with a relatively high exchangeable aluminium content (2.4 cmolc/kg) low calcium (0.99 cmolc/kg), used. Soil treated once at beginning crop monitored over seven planting seasons (PS). All treatments increased maize yield. The average increases were; times for five eight treatment, when compared control across...
Abstract Besides their potential for carbon sequestration, compost and biochar application in agriculture may constitute an alternative to mineral fertilizers by improving soil fertility productivity carbon‐poor soils. This study focused on the impact of produced from date palm residues nitrogen (N) leaching plant uptake a sandy cultivated with barley under arid climatic conditions. In addition unamended control (S), treatments (BC), urea (U), + (BCU), (C) (BCC) were tested. We followed...
Pyrogenic organic matter (PyOM) decomposes on centennial timescale in soils, but the processes regulating its decay are poorly understood. We conducted one of first studies PyOM and wood decomposition a temperate forest using isotopically labeled substrate, quantified microbial incorporation physico-chemical transformations situ. Stable-isotope (¹³C ¹⁵N) enriched precursor were added to soil at 2 cm depth ambient (N0) increased (N+) levels nitrogen fertilization. The carbon (C) (N) or...
