The 6th International Conference on Agricultural and Biological Sciences (ABS 2020), was planned to be held in the People's Republic of China. Due to the COVID-19 pandemic, ABS 2020, "Agricultural and Biological Sciences: Plant, Soil, Animal, and Environment", was the first online conference in Agricultural and Biological Sciences history. Each paper addressed a slightly different topic and provided identifiable challenges and research key questions in agriculture, agronomy, food production and security, and environmental hazards. The role of Agricultural and Biological Sciences of China is the generation of research knowledge that influence everyday activities. There were 41 manuscripts submitted, of which 25 were accepted for publication. The research domains varied and included the role of specific plant on soil C-cycling, haploid induction, and natural doubling of Zea mays L.; plant species and soil rhizosphere microflora; forest tree biomass succession and dynamics relevant to C-sequestration; making sandy land agriculture friendly; plantation age on C, N, and P stoichiometry; codon uses pattern of Gnetum luofuoense C.Y. Cheng using transcriptome data; suitability of plant landscape unit and natural parks; regeneration protocol of Jatropha curcas L., etc. The purpose of this special section is to generate an improved communication among international scientists that we hope will lead to enhanced food security.

“…Due to its limited usability and severe soil erosion, PSS is viewed by local residents as an environmental menace. Nevertheless, researchers have discovered that PSS has excellent hydrophilicity and expansibility, making it a natural water-retention agent and soil amendment [4,6]. Pisha sandstone is rich in clay-silt particles and montmorillonite, with large specific surface area, strong cation adsorption capacity, and outstanding colloidal properties, which promote the cementation and agglomeration of aeolian sandy soil in Mu Us Sandy Land [6][7][8].…”

Compounding Pisha sandstone (PSS) with sandy soil in Mu Us Sandy Land is a viable agronomical measure to effectively reduce soil erosion and improve soil quality due to the complementary characters and structures of the two materials. Aggregate stability is an important indicator to assess sandy soil erosion resistance and quality, which could be largely affected by soil surface electrochemical properties and particle interaction forces. However, the effect of the compound ratio and particle interaction forces on the aggregate stability of compound soils with Pisha sandstone and sandy soil is still unclear. Therefore, in this study, the electrochemical properties, particle interaction forces, and their effects on the aggregate stability of PSS and sandy soil at five volume ratios (0:1, 1:5, 1:2, 1:1, and 1:0) were determined to clarify the internal force mechanism of PSS to increase sandy soil structural stability in a 10-year field experiment. Experiments were measured by a combined method for the determination of surface properties and aggregate water stability. A ten-year field study revealed that the incorporation of Pisha sandstone significantly enhanced the soil organic carbon (SOC) and cation exchange capacity (CEC) (p < 0.05), while the CEC value notably increased from 4.68 to 13.76 cmol·kg−1 (p < 0.05). The soil surface potential (absolute value) and the electric field intensity gradually decreased with the increase in the Pisha sandstone content. For the compound soil particle interaction force, the addition of Pisha sandstone enhanced the van der Waals attraction force, reduced the net repulsive force between compound soil particles, and promoted the agglomeration of aeolian sandy soil. The overall trend of the aggregate breaking strength of compound soils under different addition ratios of PSS was 1:0 > 1:1 > 0:1 > 1:5 > 1:2. When the Pisha sandstone content in the compound soils was <50%, the aggregate stability was mainly influenced by compound soil particle interaction forces, and the interaction force increase was the key reason for the aggregate breakdown. When the Pisha sandstone content in the compound soils was ≥50%, the aggregate stability was affected by the combined effects of the compound soil particle composition and particle interaction forces. These results indicate that PSS addition ratios and particle interaction force are important factors affecting the structural stability of compound soils, in which the volume ratio of PSS to sandy soil of 1:2 is the appropriate ratio. Our study provides some theoretical references for further understanding of the compound soil structure improvement and sandy soil erosion control in Mu Us Sandy Land.

Global climate change and the increasing population have increased the difficulties associated with grain production. Several measures have been established to maintain a high crop yield, while preserving or increasing soil health, including biochar application to soil, and producing new complex soil with soil amendment application, e.g., biochar and soft rocks. However, previous studies have focused on the effect of complex soil on a single crop but have not considered crop rotation. In this study, field plots with foxtail millet cultivated for two years under biochar and soft rock application were selected for licorice cultivation to detect the effects of biochar and soft rock application on soil properties and licorice yield. The results showed that the biochar-treated plot had the highest licorice biomass (251.76 g/m2), followed by the combined biochar and soft rock treatment, and that the soft rock and control treatments had the lowest licorice biomass (97.65 g/m2). Plants in biochar-treated plots had the highest liquiritin and glycyrrhizic acid contents, followed by those under soft rock treatment. Soft rocks and biochar increased the soil catalase activity, organic matter, oxalic acid, tartaric acid, formic acid, and available phosphorus (AP). Correlation analysis showed that the licorice biomass was significantly positively correlated with oxalic acid and AP and negatively correlated with soil pH. AP was positively correlated with catalase activity and oxalic acid (p < 0.05) and negatively correlated with soil pH (p < 0.05). Therefore, it can be concluded that the addition of biochar and soft rocks for two years could increase soil organic acid contents (especially that of oxalic acid), which function to reduce soil pH, increase soil AP content, and enhance licorice biomass.
