Alfalfa with Forage Crop Rotation Alleviates Continuous Alfalfa Obstacles through Regulating Soil Enzymes and Bacterial Community Structures

Agronomy, Journal Year: 2024, Volume and Issue: 14(7), P. 1349 - 1349

Published: June 21, 2024

Alfalfa is a perennial herbaceous forage legume that significantly and adversely affected by monocropping. Crop rotation the most effective measure to overcome continuous cropping obstacles. However, mechanisms of how bacterial communities are potential links between these effects systems remain poorly understood. Based on long-term field experiments with alfalfa crops in black soil region western Songnen Plain Northeast China, alterations community structure using high-throughput sequencing 16S rRNA gene chemical properties enzyme activities were analyzed. The alfalfa–forage oats–silage maize–alfalfa alfalfa–silage maize–forage oats–alfalfa system increase levels total phosphorus available phosphorus, promote acid phosphatase, β-glucosidase, leucine aminopeptidase, N-acetyl-β-glucosaminidase comparison alfalfa. While crop did not affect α-diversity bacteria, it altered composition structure. Some key taxa enriched soils, including Bacillus, Sphingobium, Paenibacillus, Hydrogenispora, Rubrobacter, Haliangium, Rubellimicrobium. Additionally, increased stability complexity co-occurrence network. our findings, we recommend promoting as ideal practices for overcoming challenges associated These only enhance nutrient content but also foster beneficial microbial community, ultimately improving functionality performance.

Impact of Vermicompost Formulations on Black Carrot Yield, Quality, and Soil Fertility

Journal of Soil Plant and Environment, Journal Year: 2024, Volume and Issue: unknown, P. 15 - 36

Published: Oct. 24, 2024

Excessive use of chemical fertilizers and declining soil fertility pose significant challenges to sustainable agriculture, often leading degraded health reduced crop quality. This experiment aimed evaluate alternative fertilization strategies optimize black carrot yield quality while improving fertility. Organic residues, including paddy straw deciduous tree leaves, were combined with cow dung biogas slurry in a 1:1 ratio prepare vermicompost treatments, which tested along integrated nutrient management fertilizer treatments. Over two years, the data revealed that management, involving 50% recommended dose leaves vermicompost, resulted highest attributes carrot, control treatment produced lowest productivity. The also showed greater improvements properties, pH, electrical conductivity (EC), organic carbon (OC), cation exchange capacity (CEC), nitrogen (N), phosphorus (P), potassium (K), micronutrients, especially later years study. is likely due initially low content experimental soil, amendments typically taking three four elicit positive response. Overall, study demonstrates more effective enhancing both fertility, providing approach production long-term health.

Sewage Sludge in Agricultural Lands: The Legislative Framework in EU-28

Sustainability, Journal Year: 2024, Volume and Issue: 16(24), P. 10946 - 10946

Published: Dec. 13, 2024

Incorporating sewage sludge (SS) into soils presents a cost-effective and environmentally friendly option compared to conventional farming practices. However, SS could be perceived as double-edged sword, it may contain broad spectrum of contaminants, such heavy metals (HMs), microplastics (MPs), Pharmaceuticals in the Environment (PIE), personal care products (PSPs), raising concerns for soil health, water resources, food safety, human health. Council Directive 86/278/EEC, which regulates application agriculture, specifies limits six HMs but has not undergone substantive revisions since its inception 1986, until release updated working document SWD-2023-{final 158}. This study critically examines legislative landscape across European Union (EU) Member States (MSs), identifying heterogeneity implementation, regulatory gaps, absence thresholds emerging contaminants. The results reveal significant disparities permissible concentrations MSs comparison international guidelines established by Food Agriculture Organization (FAO) World Health (WHO). Furthermore, measures MPs, PIE, other common pollutants underscores critical deficiencies current framework. These inconsistencies contribute varying levels health EU highlight need harmonized approach. findings this imperative comprehensive overhaul framework governing application. As evidenced, establishment contaminant thresholds, rigorous monitoring protocols, provisions emergent is essential addressing identified enhancing coherence, promoting sustainable agricultural practices aligned with EU’s environmental public objectives.
