“…This may be related to the species type and ecosystem in which it thrives. A crude protein content of 7.25 ± 0.07% was found in L. glaucum, thus being in the range mentioned by Orlov and Sadovnikova [42,43] (5-10%) for Bryophytes. The volatile matter content of L. glaucum was 38.15 ± 1.78%, which was more than two-fold higher than attributed for other moss species (0.04-14.5%) [44].…”

Salinity-induced soil degradation poses a significant challenge to agricultural productivity and requires innovative crop-management strategies. In this study, the synergistic effect of biochar and TiO2 nanoparticles (NPs) obtained from moss (Leucobryum glaucum (Hedw.) Ångstr.) biomass on the growth, yield, biochemical, and enzymatic response of Chinese spinach (Amaranthus dubius L.) grown under salinity stress was investigated. Purposely, A. dubius was grown under different combinations of arable soil, biochar, TiO2 NPs, and saline soils. The produced biochar and TiO2 NPs were characterized using microscopy image analysis, X-ray diffraction patterns (XRD), energy-dispersive X-ray spectroscopy (EDX), zeta potential, particle size distribution, and Fourier-transform infrared spectroscopy (FTIR). The results showed that saline stress caused a significant (p < 0.05) decline in growth, yield, and biochemical constituents of A. dubius compared to control treatments. However, the combined application of biochar and TiO2 NPs significantly (p < 0.05) alleviated the saline stress and resulted in optimum fresh weight (30.81 g/plant), dry weight (4.90 g/plant), shoot and root length (28.64 and 12.54 cm), lead number (17.50), leaf area (12.50 cm2/plant), chlorophyll (2.36 mg/g), carotenoids (2.85 mg/g), and relative water content (82.10%). Biochar and TiO2-NP application helped to reduce the levels of stress enzymes such as catalase (2.93 µmol/min/mg P), superoxide dismutase (SOD: 2.47 EU/g P), peroxidase (POD: 40.03 EU/min/g P), and ascorbate peroxidase (3.10 mM/mg P) in saline soil. The findings of this study suggest that the combination of nanotechnology and biochar derived from unconventional biomass can be a viable option to mitigate salinity-related challenges and enhance crop yield.

The experiment was conducted at the Research Farm of Sher-e-Bangla Agricultural University, Dhaka to find out the effect of soil enhancer (XXL) and fertilizers on the morpho-physiological and yield attributes of BRRI dhan28 in Boro season. The experiment comprised one factor viz. T 1 = Control, T 2 =100% recommended dose of fertilizer, T 3 = 100% dose of XXL without fertilizer, T 4 =100% dose of XXL + 100% recommended dose of fertilizer, T 5 =50% dose of XXL + 50% recommended dose of fertilizer, T 6 =50% dose of XXL + 100% recommended dose of fertilizer, T 7 =100% dose of XXL + 50% recommended dose of fertilizer and T 8 =100% dose of XXL + 75% recommended dose of fertilizer. The experiment was laid out in a Randomized Complete Block Original Research Article

“…The most mobile fractions of Hg are water F1 and acid-soluble F2 available to herbs from soil solutions. The organic F3 and mineral F4 fractions represent a potential reserve of soil Hg, which, under changes in humidity, temperature, pH, under the influence of microorganisms and physicochemical interactions of soil components, can replenish the amount of bioavailable Hg in the soil [14][15][16]31]. The most stable and poorly soluble are sulfide F5 Hg compounds, however, these Hg compounds can also be partially dissolved, for example, under the influence of microorganisms, soil acidification, and increased moisture [22,[32][33].…”

“…It is known that the formation of mobile and bioavailable forms of Hg in soils depends mainly on the dissolution and biological destruction of its organic compounds [4]. In addition, soil organic matter is capable of 0% 20% 40% 60% 80% 100% dissolving many mineral compounds, contributing to the release of chemical elements [31].…”

Total concentrations of Hg in soils and the narrow-leaved fireweed Chamaenerion angustifolium L., as well as the forms of Hg presence in soils by the method of sequential extractions were examined to study the processes of mobilization-immobilization of Hg in the soils of the territory of the chlor-alkali plant sludge storage and the features of the bioaccumulation of this element in herbs. The determination of Hg in all samples was carried out by the atomic absorption method. High concentrations of Hg in soils near the sludge storage have been established. In almost all soil samples the amount of Hg is above the regional background. Fractionation showed that Hg in soils is found mainly in organic, strongly bound and sulfide fractions. Due to the low concentrations of Hg mobile fractions, water- and acid-soluble, a relatively low accumulation of Hg in Chamaenerion angustifolium L. was found, which was also facilitated by the barrier properties of the herb roots. Nevertheless, the accumulation of predominantly organic and strongly bound forms of Hg in soils indicates a high potential for Hg mobilization from these fractions due to changes in various physicochemical and biogeochemical properties of soils.
