“…To increase the soil C stocks, the agricultural practices must be adapted to local conditions and must have the capacity to increase biomass production and, consequently, the input of C into the soil. In [59], Rumpel et al highlight that keeping the soil covered, as well as effective nutrient management, are effective agricultural practices to recover and increase carbon stocks in the soil. Simultaneously, they must prevent this C from being released into the atmosphere or transferred to other reservoirs at harvest [22].…”

“…The diversification of plant species in agricultural systems with a grass-legume species mixture is recommended as a climate-smart farming practice [12,62]. Grasses can remove large amounts of C from the atmosphere, as they produce high biomass quantities [59]. Legumes will contribute to the nutrition of these plants, which can intensify biomass production without fertilizer application.…”

New agricultural practices and land-use intensification in the Cerrado biome have affected the soil carbon stocks. A major part of the native vegetation of the Brazilian Cerrado, a tropical savanna-like ecoregion, has been replaced by crops, which has caused changes in the soil carbon (C) stocks. To ensure the sustainability of this intensified agricultural production, actions have been taken to increase soil C stocks and mitigate greenhouse gas emissions. In the last two decades, new agricultural practices have been adopted in the Cerrado region, and their impact on C stocks needs to be better understood. This subject has been addressed in a systematic review of the existing data in the literature, consisting of 63 articles from the Scopus database. Our review showed that the replacement of Cerrado vegetation by crop species decreased the original soil C stocks (depth 0–30 cm) by 73%, with a peak loss of 61.14 Mg ha−1. However, when analyzing the 0–100 cm layer, 52.4% of the C stock data were higher under cultivated areas than in native Cerrado soils, with a peak gain of 93.6 Mg ha−1. The agricultural practices implemented in the Brazilian Cerrado make low-carbon agriculture in this biome possible.

“…From a farmer's perspective, the dependency on soil texture and initial SOC stock raise concerns about fairness and equal treatment within the context of carbon payments, for instance, as Rosinger et al (2023) discussed. This is because farmers whose soils do not have the potential to store carbon in stable forms may not be equally rewarded compared to landholders who receive compensation based on the amount of carbon sequestered (Rumpel et al, 2023;Sperow, 2020). Further research, therefore, is needed to understand the connection between pedological and agronomic factors in SOC storage and the socio-economic and political barriers to adopting soil management practices and carbon farming strategies.…”

“…They have the ability to modify the composition of soil carbon through various mechanisms associated with carbon sequestration, ultimately influencing the carbon cycle within the soil [9][10][11][12]. Studies have shown that the return of organic matter to the field has been proven to increase SOC storage [13][14][15][16][17] and promote the stability of the soil carbon pool [18]. Straw return has been found to facilitate the accumulation of labile organic carbon components [19].…”

The return of straw and manure to agricultural fields can impact soil organic carbon (SOC) and biological properties. However, there is a lack of research on how using swine manure, maize straw, and various conditioners together affects soil bacterial and fungal populations. This study aimed to investigate six treatments, namely, only maize straw (S00), maize straw combined with swine manure (S0Z), maize straw combined with biochar and swine manure (SCZ), maize straw combined with boron slag and swine manure (SBZ), maize straw combined with biological agent and swine manure (SJZ), and maize straw combined with bio-organic fertilizer and swine manure (SFZ). The results showed that after the two-year return, all treatments increased the SOC content in 2023, which was 12.55–26.89% higher than S00, and the SCZ treatment significantly increased the soil organic carbon (SOC), dissolved organic carbon (DOC), easily oxidizable carbon (EOC), particulate organic carbon (POC), and microbial biomass carbon (MBC) content by 26.89%, 25.44%, 56.88%, 16.08%, and 43.54%, compared to S00. A redundancy analysis (RDA) showed that the continuous application of manure, maize straw, and conditioners has a positive impact on the diversity and abundance of soil microbial communities, enhancing the accumulation of soil carbon. Furthermore, our research revealed that soil fungi exhibited higher sensitivity in soil carbon composition following the addition of manure, straw, and conditioners to agricultural fields than bacteria. In conclusion, the addition of different conditioners to the fields is beneficial to biodiversity conservation from the perspective of achieving soil carbon storage and soil protection. Our findings suggested that the combination of maize straw, biochar, and swine manure has been proven to be the most effective treatment for increasing labile organic carbon fractions and enhancing the microbial community.
