Phosphorus Balance Trend in Albania Agriculture During the Period 1950–2019

Hence, this research sought to determine soil phosphorus balance at national level during the period 1950-2013, using the OECD method. In cases of positive phosphorus balance, freshwater quality is threatened by eutrophication, while in cases of negative balance, plant yield may decrease. The results revealed that for the most part of the study period, the phosphorus balance in Albania was positive, reaching a record of about 22 kg/ha in 1990. Albania is included in the group of countries with the largest deficit compared to other EU countries and the OECD in terms of phosphorus shortage. The value of phosphorus use efficiency, as an average for the entire study period, was 29 percent, or about 3. 7 times lower, compared to the average value for this indicator in the EU-28, indicating the urgent need to continue plant production methods including manuring.

Segregation of a Phosphorus Rich Phase During Differential Solidification of BOF Slag

This research investigated the segregation behavior of the phosphorus rich phase of steelmaking slag from lab to industrial scale using computational fluid dynamics in order to find a suitable separation strategy for the P-rich phase. Following solidification, both simulation and experimental results revealed a rise in phosphorus concentration in the top region of the crucible. Separation of phosphorus from the rest of the slag pot and slag pit separation is likely in both batch and slag pit configurations, according to the P-rich phase within the slag.

Flame retardant and hydrophobic cotton using a unique phosphorus–nitrogen–silicon-containing coating

A rough surface and XPS spectra reveal the coating on the cotton surface, according to a SEM photograph. According to direct flame experiments, the as-prepared coating can prevent the cotton from flaming. The limiting oxygen index increased from 18. 0% for the uncoated fabric to 32. 0% for the THPO/Guanazole-treated sample and 27. 0% for the THPO/Guanazole-treated sample, which was 27. 0% for the THPO/Guanazole-treated sample. In addition, with more THPO/Guanazole, a gradual decrease in PHRR values for C2 and 76% for C3 was slower than untreated cotton, which was 60% for C2 and 76% for C3 decreased. In addition, the coated cotton exhibits outstanding hydrophobicity with a water contact angle of 133 degrees U00b0.

Nutrient addition and warming alter the soil phosphorus cycle in grasslands: A global meta-analysis

Several nutrient addition and warming experiments have been carried out in grasslands; however, the global pattern of nutrient addition and atmospheric warming has been uncertain. Conclusions According to our report, nitrogen addition reduced microbial biomass P however increased litter P concentration and available P. Experimental warming reduced microbial biomass P and available P, but litter P concentrations increased. Phosphorous solutions like air temperature and soil pH were largely dependent on environmental conditions such as air temperature and soil pH. Conclusion Notwithstanding's findings Notwithstanding may promote P mineralization and possibly increase the transformation of refractory or resistant forms of soil inorganic P, which can lead to the transformation of refractory or resistant forms of soil inorganic P, whereas experimental warming accelerates the P cycle by regulating plant recruitment and enzyme activity. To estimate the P cycle in grassland soils in the future, it is vital to understand the rapid shifts in soil microbial and enzyme activity.

Effect of Temperature on the Carbon, Nitrogen, and Phosphorus Nutrient Budgets of Steelhead Trout (Oncorhynchus mykiss) with Different Sizes

This study was conducted to determine the effects of temperature on adult steelhead trout with different body sizes' carbon, nitrogen, and phosphorus nutrient budgets. According to nonlinear multiple regression results, 15 u00b0C was the approximate optimal temperature for steelhead trout feeding and growth. As body weight increased, the feed intake rate, fecal production rate, ammonia excretion rate, ammonia excretion rate, phosphorus excretion rate, and scope of the fish's body weight decreased. The absorption efficiencies of P in the S2 and S3 treatments were markedly higher than those in the S1 condition, and the absorption efficiencies of P increased as body weight increased, leading to an increased absorption efficiencies of C. With changes in the temperature and body size of fish, the daily ratio should be adjusted during the culture of steelhead trout.

Preparation of functionalized mesoporous La-SBA-15@Fe_3O_4 shell/core nanocomposite for adsorption of phosphorus

In this work, lanthanum-modified the shell-u2013 core magnetic nanocomposites with Fe_3O_4 core and homogeneous mesoporous silica shell were prepared, which was then tested. To demonstrate adsorption isotherm, the kinetic study of adsorption rate and adsorption equilibrium was used.

Phosphorus reduction behavior of high-phosphate iron ore during hydrogen-rich sintering

Because of its high phosphorus content and complicated ore phase structure, the High-phosphorus iron ore deposit is classified as a refractory iron ore. With apatite reduction, the metal iron builds, and a portion of the reduced phosphorus gas is converted by the metal iron to produce stable iron–u2014phosphorus compounds, resulting in a significant decrease in the dephosphorization rate. The reduced phosphorus gas decline is concentrated in the sintering and burning zones, and it is condensed and adsorbed in part by the sintering bed as passing through the drying zone and into the wet zone. Apatite reduction has an activation energy of 80. 42 kJ/mol based on the Ozawa formula of the iso-conversion rate. A differential method and an integral approach are used to determine the mechanism of apatite reduction's reduction.

Silicon-Rich Agro-wastes in Conjunction with Phosphate-Solubilizing Microbe Can Synergistically Solubilize the Recalcitrant Soil Phosphorus in a semi-arid Tropical Inceptisol

Researchers are looking for ways to exploit the soil's recalcitrant phosphorus pool as rock phosphate deposits depleting rapidly. Si_250 and Si_375 enhanced soluble Si and solution P by 1. 46% and 17%, respectively, over no PSB, while Si_125 and Si_250 increased soluble Si and solution P by 49% and 57%, respectively over Si_0. Native soil P content P was dissolved by the PSB at 17. 63 mg kg/u22121, whereas Si_125 and Si_250 solubilized 14. 43 and 20. 17 mg kg/u22121. According to path analysis, it was an organic P that mainly contributed to total P solubilization, although iron-bound P, as well as soluble and loosely bound P, significantly influenced soil inorganic P solubilization. Both application of Si-rich ashes and PSB could be a game changer in substituting crop fertilizers with costly P fertilizers.

Formable porous biochar loaded with La-Fe(hydr)oxides/montmorillonite for efficient removal of phosphorus in wastewater: process and mechanisms

P and very little La/Fe leaching are present at sorption pore sites for P and almost no La/Fe leaching. The development of biochar-based granule-like adsorbents suitable for scaled-up application of water treatment is gaining increasing interest in the field of water treatment. Montmorillonite's acted as a binder that increased the density of the granulated biochar, although Fe promoted the surface charge and eased dispersion of La, which was responsible for selective phosphate removal. LaFe/MB's phosphate adsorption kinetics and a high maximum adsorption capacity were shown, which were greater than those of many existing granularized materials. After four adsorption cycles, LaFe/MB could be revived and maintained 76. 7% of its initial phosphate adsorption capacity after four cycles of desorption and recyclability experiments, according to four adsorption cycles. The study findings reveal that LaFe/MB has high application prospects for advanced phosphate removal from wastewater.
