Abstract Soil contamination by Pb can result from different anthropogenic sources such as lead-based paints, gasoline, pesticides, coal burning, mining, among others. This work aimed to evaluate the potential of P-loaded biochar (Biochar-based slow-release P fertilizer) remediate a Pb-contaminated soil. In addition, we aim propose biomonitoring alternative after soil remediation. First, rice husk-derived was obtained at temperatures (450, 500, 550, and 600 °C) (raw biochars). Then, part resulting material activated. Later, raw biochars activated were immersed in saturated KH 2 PO 4 solution produce biochars. The ability materials immobilize increase bioavailability evaluated an incubation test. incorporated into doses 0.5, 1.0, 2.0%. After 45 days, samples taken biomonitor remediation process using two bioindicators: phytotoxicity test enzyme activity. Activated produced 500 °C has been found present best conditions for significantly reduced increased P. enzymatic activity correlated with decrease bioavailable but not Biomonitoring is promising evaluation soils processes.

Agronomy, Год журнала: 2023, Номер 13(9), С. 2192 - 2192

Опубликована: Авг. 22, 2023

The steadfast propensity to global warming has had a severe impact on overall viticulture. Given the observed increase in growing season temperatures Europe (+1.7 °C from 1950 2004), between 2000 and 2049, it is assumed that for major wine regions will average by about +0.42 per decade generally +2.04 °C. Phenolic compound development affected environmental parameters such as ultraviolet (UV) radiation, sunlight, maximum minimum temperatures, grapevine water status. Proanthocyanidins, flavan-3-ol monomers, other pigmented polymers are impacted soil management canopy handling strategies, well obtaining microclimate around developing bunch. This review, after necessary summary of synthesis phenolic compounds berry (flavonoids non-flavonoids) let lector delve into topic, describes climate change therefore factors their accumulation storage throughout ripening harvesting. For example, high can reduce total concentrations skin anthocyanin; 35 temperature entirely obstructed anthocyanin synthesis, instead quercetin 3-glucoside could be enhanced with exposure solar radiation. In addition, increments via deficit relative abundance methoxylated anthocyanins were also found. vineyard strategies mitigate degradation preserve concentration further discussed. Finally, believed today establish an elastic variable approach towards single year, moving away concept product standardization.

Materials, Год журнала: 2023, Номер 16(6), С. 2142 - 2142

Опубликована: Март 7, 2023

Waste fly ash, with both low (with the addition of vermiculite) and high contents unburned coal, were subjected to hydrothermal syntheses aiming obtain zeolite composite materials-zeolite + vermiculite (NaX-Ver) carbon (NaX-C). The composites compared parent obtained from waste ash a content (NaX-FA). In this study, physicochemical characteristics materials evaluated. potential application investigated zeolites for adsorption ammonium ions aqueous solutions was determined. Composite NaX-Ver NaX-FA characterized by comparable capacities toward 38.46 40.00 mg (NH4+) g-1, respectively. nearly 2-fold lower capacity NaX-C (21.05 g-1) probably result availability ion exchange sites within material. Adsorbents also regenerated using 1 M NaCl solution at pH 10 3 cycles adsorption-desorption experiments, which proved only small reduction in properties. This study follows current trend utilization (fly ash) removal pollutants respect their reuse, remains line goals circular economy.

The foliar application of zeolites has been proven to positively affect plant physiology suggesting that it could improve growth, however, this topic little studied. Two field trials were carried out (in 2021 and 2022) study the potential beneficial effect natural zeolite particle films on processing tomato crops. Natural i) clinoptinolite + mordenite (CubZeo) ii) micronized (BigZeo) sprayed onto plants six times in central crop cycles. In both trials, BigZeo promoted leaf fruit dry mass (DM) accumulation, area from early stage compared water-sprayed (Control). final aerial DM enhanced more year with favourable (+39.2%) (2022) than stressing thermal conditions (2021) (+12.1%). Concurrently, marketable yield was improved by 36% years positive effects also total soluble solids. Under heat stress, CubZeo showed even lower Control, remained similar due higher incidence blossom-end-rot (BER) untreated plants. 2022, expansion if a lesser extent treatment. fruits concentrations K, Ca, Mg rose zeolite-treated Ca level can explain occurrence BER plants, particularly CubZeo. Si observed at highest stems BigZeo-treated followed Control ones. accumulation best responses elicited BigZeo, whereas did not appear involve changes photosynthetic machinery. However, further comprehensive investigations are needed define film characteristics related physiological nutritional

Impact of some amendments on kinetics of leaching dissolved organic carbon and ammonium in calcareous sandy soil under vinasse addition

Scientific Reports, Год журнала: 2024, Номер 14(1)

Опубликована: Фев. 20, 2024

Abstract The access of vinasse leachates to water bodies and groundwater exacerbates environmental problems, especially eutrophication. Therefore, a column experiment was performed examine the effect adding zeolite (ZL), bone char (BC), wood chips biochar (WCB) in presence on carbon dioxide (CO 2 ) emission, leaching dissolved organic (DOC) ammonium (NH 4 + calcareous sandy soil, as well studying kinetics ammonium. This contains four treatments: soil alone (CK), (SZL), (SBC), (SWCB). These amendments were applied at level 4%. Vinasse added all treatments 13 mL per column. leached total cumulative DOC soluble amounts decreased significantly with applying ZL, BC, WCB compared alone. effectiveness these lowering is order SBC > SWCB SZL CK. However, decreasing NH rate constant (k) application treatment. In vinasse, apparent half-life from 8.1, 12.9, 36.7, 15.5 days for CK, SZL, SBC, treatments, respectively. Half-life values addition 10.1, 39.5, 28.5, 37.9 Amending BC increased phosphorus availability, however, ZL caused significant increase available potassium control According results, it recommended not add soils, but preferred be co-applied amendment 4% better than WCB. would decrease table enhance nutrient retention which turn, plays vital role reducing harmful improving fertility.

Sustainability, Год журнала: 2025, Номер 17(5), С. 2178 - 2178

Опубликована: Март 3, 2025

Nitrogen (N) fertilizer application is one of the most crucial agronomic management practices for increasing grain yield in maize crops. However, long may adversely affect soil quality. For achieving sustainable agricultural production, current research set out to evaluate short-term effects addition zeolite as a amendment and N fertilization on growth, yield, quality, N- water-use efficiency three locations (Athens, Messolonghi, Karditsa) Greece. Each experiment up during spring–summer 2024 cultivation period was laid split-plot design with main plots (Zeolite treatments: 0, 5, 7.5 t ha−1) four sub-plots (N 100, 150, 200 kg ha−1). The results revealed that rate from 0 ha−1 led significant increase highest value (13.46, 12.46, 14.83 Athens, Karditsa, respectively) observed at ha−1. In same manner, inorganic ha−1, also increased yield. general, properties (soil organic matter, total nitrogen, porosity, moisture content, infiltration rate), root shoot growth (root length density, plant height, leaf area index dry weight), content uptake grains, aerial biomass, well as, thousand kernel weight, harvest (NHI), water use (WUE), were positively affected by both examined factors. conclusion, this study proved rates respectively, improved properties, promoted development, biomass uptake, NHI, WUE crop cultivated clay–loam soils under Mediterranean conditions, where experimental trials up.
