Abstract Salinity stress adversely affects agricultural productivity by disrupting water uptake, causing nutrient imbalances, and leading to ion toxicity. Excessive salts in the soil hinder crops root growth damage cellular functions, reducing photosynthetic capacity inducing oxidative stress. Stomatal closure further limits carbon dioxide uptake that negatively impact plant growth. To ensure sustainable agriculture salt-affected regions, it is essential implement strategies like using biofertilizers (e.g. arbuscular mycorrhizae fungi = AMF) activated biochar. Both amendments can potentially mitigate salinity regulating antioxidants, gas exchange attributes chlorophyll contents. The current study aims explore effect of EDTA-chelated biochar (ECB) with without AMF on maize under Five levels ECB (0, 0.2, 0.4, 0.6 0.8%) were applied, AMF.

Maize is an important cereal in many developed and developing countries of the world. One primary challenges for maize cultivation soil acidity. Acidic a major constrain achieving food security requiring sustainable solutions. Biochar, pyrogenic carbon-rich material, carries reactive surfaces (i.e., high surface area variable charges). Therefore, it facilitates nutrient retention gradual release to plants, thereby supporting crop growth. However, combine effects functionalized biochar with microbes on phosphorus (P) bioavailability plant performance remain unclear. This study investigates application different oxidized biochars (i.e.,fresh rice husk (RHB), pH adjusted RHB control) phosphate solubilizing bacteria <em>Pseudomonas aeruginosa</em>, properties including dynamics grown acid soil. Biochar was using 10% hydrogen peroxide while 8.5. pots having 20 kg or soil-biochar mixture. Overall, treatments increased yield greater giving significant × interactions.

Biochar in Sustainable Agriculture: Fertilizer from Natural Resources?

IntechOpen eBooks, Год журнала: 2025, Номер unknown

Опубликована: Янв. 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.

Peat is considered a contentious input in horticulture. Therefore, there search for suitable alternatives with similar properties that can be used partial or complete peat substitution growing media. Poultry-manure-derived biochar (PMB) such an alternative. This study aimed at determining the of PMBs obtained through pyrolysis selected temperatures and assessing their potentials to substitute media based on properties. The scope included laboratory-scale poultry manure 425–725 °C; determination physico-chemical physical biochars, including contaminants; assessment produced biochars as substitutes. contained less than 36% total organic carbon (TOC). contents P K were about 2.03–3.91% 2.74–5.13%, respectively. did not retain N. They safely concentrations heavy metals, polycyclic aromatic hydrocarbons (PAHs), polychlorinatd biphenyls (PCBs), dioxins, furans are within permissible values (except Cr). Due high pH (9.24–12.35), they have liming effect. High water holding capacity (WHC) range 158–232% w/w could allow maintenance moisture 525 °C, 625 725 °C showed required stability (H/Corg < 0.7).

Abstract The utilization of biochar’s as soil amendments for enhancing nutrient retention in subsoils present potential limitations. To address this issue, we conducted a greenhouse experiment to assess the effects various derived from animal manures (swine manure, poultry litter, cattle manure) and plant residues (rice straw, soybean corn straw) when applied surface an acidic soil. Our study focused on wheat crops under no-tillage system, with subsequent evaluation residual impacts soybeans. experimental design involved application at different rates i.e. 10 20 Mg ha −1 , followed by assessment their influence NPK levels, pH, exchangeable Al stratified layers (0–5, 5–10, 10–15, 15–25 cm). Furthermore, investigated interplay between biochar doses nitrogen (N) top 5 cm soil, specifically examining $${\text{NO}}_{{3}}^{ - }$$ NO 3 - $${\text{NH}}_{{4}}^{ + NH 4 + P K levels. findings revealed that N significantly affected concentrations. However, deeper layers, no significant differences were observed among or without application. Interestingly, levels impacted throughout all depths, regardless presence absence Moreover, up depth induced favorable changes pH reduced Al. In contrast, experienced decrease increase following treatment. conclusion, our demonstrates can effectively retain nutrients, enhance Al, independent type dosage system. Nonetheless, efficacy may vary nutrient, warranting careful consideration maximizing benefits sustainable agricultural practices.

Biofertilization with Liquid Vermicompost-Activated Biochar Enhances Microbial Activity and Soil Properties

Soil Systems, Год журнала: 2024, Номер 8(2), С. 54 - 54

Опубликована: Май 16, 2024

Biochar (Bc) and liquid vermicompost extracts (LVEs) are increasingly being used as biofertilizers in agriculture to promote soil-microbe-crop interactions. However, although both these products can potentially act synergistically due their complementary characteristics, co-application different soils has not yet been investigated. Therefore, firstly, an LVE-activated biochar (BLVE) was experimentally formulated the persistence of LVE bacteria over a 60-day storage period determined. The total number increased by 10-fold after 7 days stable throughout entire period. In addition, changes composition bacterial community were observed 30 storage, indicating that taxa less represented pure may be advantaged upon colonization. Secondly, microcosm experiment performed evaluate whether biological fertility enzyme activities two soils, differing organic matter content, could enhanced addition biochar. this experiment, three doses Bc, LVE, BLVE against carbon-related index (i.e., index, BFI) 21-day incubation tested. treatment yielded best results BFI +32%, +38%). This indicates Bc LVEs soil fertility, quality, microbial activity. By integrating into management practices, farmers achieve higher crop yields healthier products.
