Contaminant containment measures are often necessary to prevent or minimize offsite movement of contaminated materials for disposal other purposes when they can be buried left in place due extensive subsurface contamination. These include physical, chemical, and biological technologies such as impermeable permeable barriers, stabilization solidification, phytostabilization. is advantageous because it stop contaminant plumes from migrating further allow pollutant reduction at sites where the source inaccessible cannot removed. Moreover, unlike options, do not require excavation substrates. However, regular inspections monitor mobilization migration. This review critically evaluates sources persistent contaminants, different approaches remediation, various physical-chemical-biological processes containment. Additionally, provides case studies operations under real simulated field conditions. In summary, essential preventing contamination reducing risks public health environment. While periodic monitoring necessary, benefits make a valuable remediation option methods feasible.

Organic fertilizer can improve soil management and alleviate nutrient loss caused by excessive fertilization. This study determines a fertilization scheme that achieve high stable crop yield effective exploring the effects of different organic proportions on content, utilization rate, wheat yield. The experiment was conducted from 2018 to 2020 using Xinchun 38 variety gray desert soil. used six treatments: no (CK), with normal nitrogen phosphorus (CF). amount conventional chemical reduced 6%, 12%, 18%, 24%, respectively, supplemented same proportion. experimental treatment codes were SF6, SF12, SF18, SF24, respectively. Plant samples growth stages 0–20 cm collected analyze content matter; dry matter accumulation, yield, components measured at harvest stage. Soil available nitrogen, phosphorus, potassium, contents increased replacement ratio after three consecutive years application. nutrients in treated SF18 SF24 significantly higher than those CK CF. accumulation increasing rates Nitrogen rates, partial productivity, agricultural use efficiency also increased, treatments having other treatments. number ears, 1000-grain weight, produced best results. Therefore, continuously as for increase availability, which rate fertilizer, thereby achieving stability even significant

Effects of organic fertilizer incorporation practices on crops yield, soil quality, and soil fauna feeding activity in the wheat-maize rotation system

Frontiers in Environmental Science, Год журнала: 2022, Номер 10

The decline in soil quality is becoming a significant process of degradation. Optimizing organic fertilizer incorporation practices cropland essential to enhancing crop productivity and health. However, that requires comprehensive understanding yield reaction across an application gradient fertilizer. We investigated the effect on yield, quality, fauna feeding activity from fluvo-aquic soils wheat ( Triticum aestivum )-maize Zea mays ) rotation field. six treatments included were unfertilized N control (UC), traditional chemical (TF, 600 kg ha −1 year ), recommended fertilization (RF, 400 with no rate, low-level 15.0 (RFLO), medium-level 30.0 (RFMO), high-level 45.0 t (RFHO) application, respectively. research findings show increased 26.4%–44.6% for 12.5%–40.8% maize compared RF plots. long-term rate carbon 54.7% 110.6% versus UC plots 27.9%–74.0% (TF RF) treatments, total nitrogen content 41.8% 59.2%, 24.6%–39.2%. inorganic combined significantly enhanced sucrose (30.1%–51.9%), urease (28.4%–38.3%), β-1,4-glucosidase (34.6%–122.4%) activity. Still, nitrite reductase, polyphenol oxidase, catalase lower 27.3%–49.9%, 8.5%–26.3% 23.3%–34.3% than single applications groups. Meanwhile, results showed improved by 35.2%–42.5%, excessive reduced level fauna.

Fertilization of Microbial Composts: A Technology for Improving Stress Resilience in Plants

Plants, Год журнала: 2023, Номер 12(20), С. 3550 - 3550

Опубликована: Окт. 12, 2023

Microbial compost plays a crucial role in improving soil health, fertility, and plant biomass. These biofertilizers, based on microorganisms, offer numerous benefits such as enhanced nutrient acquisition (N, P, K), production of hydrogen cyanide (HCN), control pathogens through induced systematic resistance. Additionally, they promote the phytohormones, siderophore, vitamins, protective enzymes, antibiotics, further contributing to sustainability optimal agricultural productivity. The escalating generation organic waste from farm operations poses significant threats environment fertility. Simultaneously, excessive utilization chemical fertilizers achieve high crop yields results detrimental impacts structure To address these challenges, sustainable agriculture system that ensures fertility minimal ecological impact is imperative. composts, developed by incorporating characterized plant-growth-promoting bacteria or fungal strains into derived waste, promising solution. with selected microbial capable thriving compost, an eco-friendly, cost-effective, alternative for practices. In this review article, we explore potential composts viable strategy growth environmental safety. By harnessing microorganisms can pave way foster healthier relationship between soil, plants, environment.

Application of biosolids to agricultural land has gained increasing attention due their rich nutrient content. There are a variety treatment processes for converting sewage sludge biosolids. Different can change the physicochemical properties raw and affect dynamics release in biosolids-amended soils. This paper reviews heat drying, alkaline treatment, composting as discusses effects these treatments on biosolid nitrogen (N) content availability. Most N remain organic forms, regardless type but considerable variation exists mean values total mineralizable across different types The highest was recorded heat-dried (HDB) (4.92%), followed by composted (CB) (2.25%) alkaline-treated (ATB) (2.14%). value similar between HDB ATB, with broader range ATB. lowest availability observed CB. Although many models have been extensively studied predicting potential mineralization soils amended amendments, limited research attempted model soil following application. With being popular, economical, eco-friendly alternative chemical N-fertilizers, understanding is important developing sound management system.
