“…Thus, compared with NT, tillage treatments have increased the potential to promote straw C conversion into soil C (Stemmer et al 1999;Wingeyer et al 2012). It is noteworthy that NT treatment generally results in greater soil C storage than PT and RT treatments at surface soil (Bossuyt et al 2002;Dolan et al 2006;Huggins et al 2007;Hermle et al 2008). Six et al (2002) proposed C-saturation mechanisms where larger amounts of soil C accumulate when C is far from saturation.…”

Straw incorporation (SI) is a common practice in China and has important implications for agricultural sustainability. This study aimed to quantitatively summarise the response of top soil (0-20 cm) carbon (C) to SI under different agricultural management regimes. Results indicated that compared with straw removal (SR), SI significantly increased soil C storage by 12 %. Moreover, incorporation of chopped straw with tillage treatment (ploughing and rotary tillage) increased C storage compared to unchopped straw without tillage treatment. SI implementation with upland cropping, in the northwest and northeast resulted in higher C storage compared with rice cropping, and in the northern and southern regions. Changes in soil C were observed based on SI variables, including tillage and straw amounts in fine-textured soils, however straw amount rather than tillage treatment exhibited a greater influence on soil C in coarse-textured soils. We concluded SI implementation with increased amounts of chopped straw for a longer duration was favourable to soil C sequestration in Chinese croplands. Furthermore, we estimated if SI was popularised across all of China's agricultural regions, soil C sequestration potential would reach 48.25 6.2 Tg C year −1. SI practices should therefore be encouraged.

Frações húmicas da matéria orgânica do solo cultivado com soja sobre palhada de braquiária e sorgo

A matéria orgânica do solo (MOS) é o produto de resíduos da biota, principalmente dos vegetais, parcialmente decompostos e sintetizados, em vários estádios de complexidade e diversidade estrutural. A dinâmica da matéria orgânica influencia os principais processos químicos, físicos e biológicos nos solos, e determina muitas vezes sua fertilidade. O objetivo deste estudo foi quantificar o conteúdo de ácido fúlvico, ácido húmico e humina, e avaliar o estoque destas frações em Latossolo Vermelho, cultivado com soja sobre palhada de braquiária e sorgo no cerrado goiano, município de Montividiu (GO). As amostras foram coletadas em três profundidades nos seguintes sistemas agrícolas: área com cultivo de braquiária na entressafra da soja (SB) e outra com o cultivo de sorgo na entressafra da soja (SS). Foram analisados os teores de carbono orgânico total (COT) e realizado o fracionamento químico da matéria orgânica do solo. A partir dos valores analisados, foram quantificados os estoques de carbono em cada uma das frações. Foram verificadas diferenças significativas para os teores de COT entre sistemas avaliados em todas as profundidades. Quanto às frações químicas da matéria orgânica, observou-se que houve um predomínio da fração humina (C-HU) em relação às frações ácido húmico (C-FAH) e ácido fúlvico (C-FAF) nas duas coletas avaliadas.

“…Except for the management practices on cropland, C sequestration in cropland soils was also affected by many other factors, such as climate and soil conditions (Yan, Cao, Liu, & Tao, 2007;Angers, 1997;Gregorich, Rochette, VandenBygaart, & Angers, 2000;Hermle, Anken, Leifeld, & Weisskopf, 2008). Therefore, the effect sizes of a variety of IMPs on soil C sequestration of cropland were significantly different among regions (Smith, 2004a).…”

Carbon sequestration in cropland soils which could be achieved through improved management practices (IPMs) represents an important opportunity to offset a portion of greenhouse gas emissions. North China is the main wheat and maize production region where many IMPs have been widely used during the last several decades, but the effect size and duration of IMPs on soil organic carbon (SOC) sequestration in wheat-maize double cropping system in this region is scarcely studied. In this study, a meta-analysis was conducted to compare the effect size and duration of four IMPs on SOC sequestration in wheat-maize double cropping system in north China. A total of 29 long-term experiments, consisting of 119 paired treatments were compiled in this analysis. The results indicated that the four IMPs of organic manure application (OM), organic manure combined with chemical fertilizer application (MF), straw return (SR) and reduced or no tillage (RNT) all had significant effects on SOC sequestration in the study area. On average, the IMPs of OM, MF, SR and RNT enhanced SOC density by 260, 328, 278 and 134 kg ha -1 yr -1 , respectively. The effect duration of OM, MF, SR and RNT on SOC sequestration were about 48, 26, 22 and 18 years, respectively. Accumulation enhancements of SOC for OM, MF, SR and RNT over SOC sequestration period were about 34.7%, 36.1%, 22.0% and 12.7%, respectively. OM and MF could be the appropriate practices on SOC sequestration in wheat-maize double cropping system in the research area.
