“…In fact, crops' shoot and root biomass of cover crops and grape trees were left on the field, in contrast with the cereal field and cherry farm, where residue removal and crop harvesting decreased organic inputs. These findings are in agreement with Ramesh et al [34], who found a considerable impact of land use changes on SOC and reported that chemical and biochemical soil parameters were constant under low-intensity farming practices. A similar finding was also reported by Safaei et al [35] who showed that the SOM and soil quality in natural ecosystems were considerably affected by land uses.…”

Soil Biological Fertility and Bacterial Community Response to Land Use Intensity: A Case Study in the Mediterranean Area

et al. 2019

The current study was performed to investigate the effects of three different long-term land use intensities on adjacent soil plots, namely a winter wheat field, a grass-covered vineyard, and a cherry farm, on soil biochemical, microbial, and molecular parameters. The results showed the maximum content of soil organic matter (SOM) and microbial biomass carbon (MBC) observed in the grass-covered vineyard. Basal respiration (BSR) and the cumulated respiration (CSR) after 25 days of incubation were significantly higher in the grass-covered vineyard and cherry farm, respectively (BSR 11.84 mg CO2–C kg−1 soil d−1, CSR 226.90 mg CO2–C kg−1 soil). Grass-covered vineyard showed the highest soil biological fertility index (BFI) score (20) and ranked in the class IV (good) of soil biological fertility. Cereal field and cherry farm had lower BFI scores and the corresponding BFI class was III (medium). In addition, the maximum ribosomal RNA copy number and the highest abundance of oligotrophic bacterial groups (25.52% Actinobacteria, 3.45% Firmicutes, and 1.38% Acidobacteria) were observed in the grass-covered vineyard. In conclusion, the grass-covered vineyard is a more conservative system and could have a large potential to improve total carbon storage in soil, mainly because of the cover crop residue management and the low soil perturbation through the no-tillage system.

“…For example, SOC data collected over 35 years in a semi-arid region of China showed that carbon levels were enhanced (by 453% to 757%) using a combination of best practice cultivation, mulching, and planting methods (Guoju et al, 2020). Different land uses also affect SOC, not only in terms of concentration, but also the fractions of SOC that are vulnerable to mineralization (Ramesh et al, 2019). For example, labile and humified SOC fractions have been reported to be more prone to mineralization in arable lands than in grasslands (Ukalska-Jaruga et al, 2019).…”

“…For instance, exchangeable sodium (Na + ), which is mostly found in high concentration in many areas of NE Thailand's soil, causes the dispersion of soil aggregates and accelerated organic matter loss [63]. Nonetheless, there is a lack of data for many key metal cations, such as Al 3+ and Fe 3+ , that play the role of a cationic bridge between SOC's functional group and clay minerals [88,89]. Furthermore, the position of the field in the region [85] and management practices mainly effect the distinction of exchangeable cations and electrical conductivity, as discussed in previous studies [53,60,69,82,90].…”

Soil Organic Carbon in Sandy Paddy Fields of Northeast Thailand: A Review

et al. 2020

View full text Add to dashboard Cite

Soil organic carbon (SOC) improvement has become a sustainable strategy for enhancing soil resilience and reducing greenhouse gas (GHG) emissions in the rice cropping system. For tropical soils, the SOC accumulation was limited by the unfavorable environment, likely the sandy soil area in Northeast (NE) Thailand. This review aims to quantify and understand SOC in sandy paddy fields of NE Thailand. The existing research gap for alternative management practices is also highlighted to increase ecological and agronomic values. We review previous studies to determine the factors affecting SOC dynamics in sandy paddy fields, in order to enhance SOC and sustain rice yields. High sand content, up to 50% sand, was found in 70.7% of the observations. SOC content has ranged from 0.34 to 31.2 g kg−1 for the past four decades in paddy rice soil of NE Thailand. The conventional and alternative practice managements were chosen based on either increasing rice crop yield or improving soil fertility. The lack of irrigation water during the mild dry season would physically affect carbon sequestration as the soil erosion accelerates. Meanwhile, soil chemical and microbial activity, which directly affect SOC accumulation, would be influenced by nutrient and crop residue management, including chemical fertilizer, manure and green manure, unburned rice straw, and biochar application. Increasing SOC content by 1 g kg−1 can increase rice yield by 302 kg ha−1. The predicted carbon saturation varied tremendously, from 4.1% to 140.6% (52% in average), indicating that the sandy soil in this region has the potential for greater SOC sequestration. Our review also suggests that broadening the research of rice production influenced by sandy soil is still required to implement adaptive management for sustainable agriculture and future food security.
