“…Similar results were reported by Czopek et al (2022). 29 However, recent reports indicate that, although higher soil moisture may enhance soybean yield, it concurrently diminishes quality indicators such as protein and oil content. Future research should take into account the potential antagonistic influence of γ-PGA application on soybean yield and quality, with the aim of optimizing its application rate.…”

BackgroundThe Poly‐γ‐glutamic acid (γ‐PGA) is extensively employed in agricultural practices to enhance soil water retention; however, the underlying mechanism by which γ‐PGA improves soil structure and soybean productivity in arid regions remains poorly understood. A micro‐scale field experiment was conducted in the arid region of northwest China, employing five levels [0 (CK), 10 (P1), 20 (P2), 40 (P3), and 80 kg ha−1 (P4)] of γ‐PGA to investigate its impacts on soybean yield, photosynthesis, and water use efficiency, as well as soil aggregates and water distribution.ResultsResults demonstrated the γ‐PGA application significantly improved soybean yield, photosynthesis, and chlorophyll content. The γ‐PGA application resulted in a decrease in soil aggregate content with a diameter of <0.053 mm and an increase in soil aggregates stability. The γ‐PGA application has significantly increased soil water content, particularly in the uppermost layer of soil (0–30 cm), while effectively reducing water consumption and improving water use efficiency in soybean. Overall, the P3 treatment exhibited the most pronounced enhancement in soybean yield, photosynthesis, water use efficiency, as well as soil aggregates and water distribution. In addition, the correlation matrix heatmap revealed a strong correlation between improvement of soybean yield or photosynthesis at various γ‐PGA application levels and the enhancement of soil stability or soil water content.ConclusionThe multivariate regression analysis revealed that an optimal application level of 46 kg ha−1 γ‐PGA could effectively enhance both yield and water use efficiency of soybean in the arid region of northwest China.This article is protected by copyright.

In this study, the effects of soil conditioners on the growth and development of melons and the rhizosphere soil environment were explored. The optimal amount of added soil conditioner was screened to solve the practical production problems of high-quality and high-yield thin-skinned melon. The melon variety “Da Shetou” was used as the material. Under the conditions of conventional fertilization and cultivation technology management, different soil conditioners were set up for potted melons. The effects of Pastoral soil (CK), 95% Pastoral soil + 5% volcanic ash soil conditioner (KT1), 85% Pastoral soil + 15% volcanic ash soil conditioner (KT2), 75% Pastoral soil + 25% volcanic ash soil conditioner (KT3), 65% Pastoral soil + 35% volcanic ash soil conditioner (KT4), and 55% Pastoral soil + 45% volcanic ash soil conditioner (KT5) on melon yield, quality, and rhizosphere soil characteristics were investigated. The soil microbial community was analyzed using Illumina MiSeq technology. Compared to CK, KT1, KT3, KT4, and KT5, the KT2 treatment could improve the single fruit yield of melon, increasing it by 4.35%, 2.48%, 2.31%, 5.92%, and 2.92%. Meanwhile, the highest contents of soluble protein, soluble solid, and soluble sugar in the KT2 treatment were 1.89 mg·100 g−1, 16.35%, and 46.44 mg·g−1, which were significantly higher than those in the control treatment. The contents of organic matter, total nitrogen, alkali-soluble nitrogen, nitrate nitrogen, ammonium nitrogen, available potassium, and available phosphorus in melon rhizosphere soil were the highest in the KT2 treatment. Through Alpha diversity analysis, it was found that the Chao1 index, Shannon index, and ACE index were significantly higher in the KT1 treatment than in the control, while, among all groups, the Simpson index and coverage were not significantly different. The dominant bacteria in the six treated samples were mainly Actinobacteriota, Proteobacteria, Cyanobacteria, Chloroflexi, Acidobacteria, Bacteroidetes, Myxomycota, Firmicutes, Gemmatimonadota, Verrucomicrobia, and Planctomycetes, which accounted for 96.59~97.63% of the relative abundance of all bacterial groups. Through redundancy analysis (RDA), it was found that the organic matter, electrical conductivity, available phosphorus, and nitrate nitrogen of melon rhizosphere soil were the dominant factors of bacterial community change at the dominant genus level. In summary, 15% ash soil conditioner applied on melon was the selected treatment to provide a theoretical reference for the application of soil conditioner in facility cultivation.
