This study explores agronomic management (AM) effects on soil parameters under diverse conditions. Investigating tillage practices (TP), nutrient (NM), crop rotation (CR), organic matter (OM), irrigation (IM), and mulching (MS), it aims to reveal impacts productivity, availability, microbial activity, overall health. Varied TP affect quality through compaction, porosity, erosion risk. Proper NM is vital for cycling, preventing imbalances acidification. CR disrupts pest cycles, reduces weed pressure, boosts recycling. OM enhances by influencing carbon, pH, fertility, water retention. Optimizing IM regulates content without inducing waterlogging. MS contributes content, retention, structure, temperature-moisture regulation, benefiting biota, aggregation, health agricultural productivity. The review emphasizes integrated nutrient, CR, management's positive impact fertility activity. Different variations production. Judicious implementation of these essential sustainable agriculture. synthesis identifies uncertainties proposes research directions optimizing productivity while ensuring environmental sustainability. Ongoing inquiry can guide a balanced approach between yields resilient stewardship future generations.

Introduction The partial substitution of chemical fertilizer with organic manure takes on a critical significance to enhancing soil quality and boosting sustainable agricultural development. However, rare research has studied the effects bacterial community diversity enzyme activity in maize field mountain red region Yunnan. Methods In this study, four treatments were set up which (the application rates N, P 2 O 5 K 240, 75 kg·ha −1 , respectively) was substituted by 10% (M10), 20% (M20), 30% (M30) 40% (M40) equal nitrogen, as well two control single (M0) no fertilization (CK).

Long-term fertilization can result in changes the nitrogen (N) cycle maize rhizosphere soil. However, there have been few reports on impacts of plant–soil–microbe regulatory mechanisms N In this study, soil samples were collected from a long-term experimental site located at Jilin Agricultural University, Changchun City, Province, Northeast China. We then analyzed functional genes related to cycle, enzyme activity, and root exudates under fertilizer application using metagenomics liquid chromatography analysis. aimed investigate response fertilizers, interaction among plant, soil, microbes, effect system cycle. had significant contents, N2O emissions, activity The mainly enriched degradation pathway decreased abundance fixation degradation, denitrification, assimilatory nitrate reduction (ANRA) increased participating dissimilatory (DNRA) anaerobic ammonia oxidation/hydroxylamine oxidation. environment was positively negatively microbial community composition amino acids exudates. contribution rate microorganisms highest (r2 = 0.900), followed by 0.836) 0.832). Therefore, we concluded that is main factor limiting are regulating plant–soil–microorganism system.

Saline soils pose complex environmental challenges that limit fruit tree root function. Understanding the mechanisms by which factors drive traits in zone soil is crucial for improving productivity through irrigation-based regulation of structure. This study aimed to identify primary drivers and driving environment on traits, as influenced water content saline trees. A 2-year field experiment was conducted Korla, Xinjiang, investigate effects physicochemical properties, enzyme activities, nutrients active state trace elements setting different irrigation gradients (Low: 3750 m 3 ha −1 ; Moderate: 5250 High: 6750 ). Compared low-irrigation treatment, results showed high-irrigation treatment decreased electrical conductivity pH 21.6–30.5 % 1.4–5.5 %, respectively, increased organic matter, available phosphorus, potassium 4.4–5.1 11.7–17.6 14.8–34.6 respectively.
