Toxics, Journal Year: 2025, Volume and Issue: 13(1), P. 30 - 30

Published: Jan. 1, 2025

Atrazine causes serious contamination of agricultural soils and groundwater. This study investigated the influence mechanism sterilized soil (CKs), unsterilized (CKn), amended with 45 (SsV1), 60 (SsV2), 75 (SsV3) days vermicompost (the maturity vermicompost), (SnV1), (SnV2), (SnV3) on atrazine catabolism. The degradation experiment lasted for 40 days. results showed that rates CKs, CKn, SsV1, SsV2, SsV3, SnV1, SnV2, SnV3 were 24%, 56.9%, 62.8%, 66.1%, 65.9%, 87.5%, 92.9%, 92.3%, respectively. Indigenous microorganisms capable degrading present in soil, addition enhanced degradation. humic acid content SnV2 was highest, at 4.11 g/kg, which 71.97% higher than CKn. production hydroxyatrazine, deethylatrazine, deisopropylatrazine. Vermicompost increased abundance atrazine-degrading bacteria (Mycobacterium, Devosia, etc.), introduced new (Mesorhizobium, Demequina). above best achieved addition. provides a new, efficient, economical, environmentally friendly strategy remediation atrazine-contaminated soil.

Identification of Peanut Cultivars with Low Cadmium Contents and Their Rhizosphere Microbial Characteristics in Alkaline and Acidic Cadmium-Contaminated Fields

Sustainability, Journal Year: 2025, Volume and Issue: 17(2), P. 626 - 626

Published: Jan. 15, 2025

Employing crop cultivars with low cadmium (Cd) accumulation and high yield is an effective strategy for the sustainable safe utilization of Cd-contaminated farmland. However, current understanding peanut cultivars, particularly under field conditions, limited. This study identified low-Cd their rhizosphere microbial characteristics in acidic alkaline fields moderate Cd contamination. The results indicated that LH11, FH1, LH14, YH9414 exhibited yield, kernel content reduced by 27.27% to 47.28% increased 9.27% 14.17% compared cultivar SLH. Among them, FH1 was validated achieve production two fields. A unique community formed recruitment diverse microbes, such as Alphaproteobacteria, Acidobacteria, Gemmatimonadetes, Chloroflexi, soil which might be associated immobilization promotion plant growth. Functional predictions further these findings, revealing enhanced functional pathways related proliferation, stabilization, detoxification. provides valuable germplasm resources agriculture Cd-polluted soils elucidates different conditions. These findings are important targeted management contaminated farmland ensuring food production.

Biochar in Sustainable Agriculture: Fertilizer from Natural Resources?

IntechOpen eBooks, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 20, 2025

Continuous and excessive use of synthetic fertilizers in food production generates strong pressure on agroecosystems. Therefore, it is necessary to study standardize alternatives that promote environmental health, such as biochar. Biochar (a blackish solid obtained from the pyrolysis vegetable waste, industry animal or water processing waste) characterized by its high content mineral carbon, presence functional groups, richness nutrients potassium (K+). Its soils improves organic matter cation exchange capacity (CEC), which promotes crop nutrition. In addition describing biochar manufacturing processes, this chapter aims emphasize role a fertilizer, stimulating effects soil microbiome enzymatic activity, positive plant health. Understanding biofertilizer can be considered an ecological strategy for production. However, agricultural sector must consider limitations fertilizer.

Saponin content in medicinal plants in response to application of organic and inorganic fertilizers: a meta-analysis

Frontiers in Plant Science, Journal Year: 2025, Volume and Issue: 16

Published: Feb. 11, 2025

The application of fertilizers is a key agronomic practice in the artificial cultivation medicinal plants, aiming to boost yields and enhance levels their bioactive constituents. However, systematic investigations on influence various concentration active compounds saponin-containing plants remain insufficient. In this study, 966 experimental outcomes from 29 papers were analyzed via meta-analysis examine effects organic fertilizers, inorganic combined different saponin monomers plants. findings revealed that contribute positively accumulation saponins such as Rg1 ginseng, Rb1, Rc, Rd, Re, Rg1, addition Paris polyphylla, Dioscorea, Panax quinquefolius, Platycodon grandiflorus. Moreover, was found markedly elevate concentrations Notoginsenoside R1, Ginsenoside Rb2, along with Lancemasid Quinoa saponins. use both shown effectively increase R1 ginsenosides, encompassing Rg1. Overall, results suggest individual applications have positive impact enhancement promote content, prolonged may lead soil compaction acidification, which could compromise yield quality On other hand, improve environment stimulate accumulation, they do not supply all nutrients required for sustained growth these Therefore, balanced fertilization strategy combining recommended optimal approach cultivating saponin-rich

With the development of sustainable agriculture, trials on benefits application organic fertilizers around world have been conducted. Herein, we investigated impact pure chemical (CFs) combined with compared CFs (100% CFs) and no (NFs) soil properties as well yield quality Chinese cabbage through meta-analysis. Results indicate that: (1) Compared NFs, can significantly improve increase nutrients. (2) CFs, fresh weight, number leaves, transverse diameter, leaf length, per plant, increases 8.54%, 6.6%, 9.905%, 8.42%, 10.03%; Meanwhile, (total amount above-ground parts produced) commercial (the portion that meets required standards is intended for sale) to by 10.08% 35.56%, respectively. However, it has significant income from growing cabbage. (3) content vitamin C (11.06%), soluble sugar (19.16%), protein (8.83%) reduce nitrate nitrite in cabbage, a reduction up 19.02% 20.9%, The will also certain absorption heavy metals (4) matter, carbon sequestration, nitrogen absorption, potassium showing 12.73%, 13.19%, 7.91%, 7.37%, reduces electrical conductivity available nitrogen, decreases 36.78% 38.75%, (5) increased urease sucrase, increasing 9.42% 17.16%, This study helps inform production.
