Pyrolysis is a promising technology for sewage sludge (SS) treatment providing several improvements of SS properties for soil application. However, information on the influence of pyrolytic temperature on the availability of nutrients in resulting biochar (BC) is limited. In this study, anaerobically stabilised SS was pyrolysed in a laboratory fixed-bed reactor at 220, 320, 420, 520, and 620 °C for 30 min in the N2 atmosphere. Pyrolysis resulted in a higher total content of all studied nutrients in BCs. Aromaticity and hydrophobicity of BCs increased with increasing temperatures while solubility decreased....

Steady-state strontium (88Sr) plays an important role in human health. Applying a proper amount of 88Sr to vegetables can improve their nutritional value. To investigate the biological effects of 88S on vegetables, three-leaf Chinese cabbage (Brassica rapa L.) seedlings were provided with a nutrient solution containing 0, 0.1, 0.2, 0.5, 1.0, 2.0, 5.0 and 10 mmol/L SrCl2 by the hydroponic culture. The results showed that SrCl

Capsicum annuum L. belongs to the Solanaceae family and is a species of huge economic importance and high nutritional value. A study conducted in the years 2014-2015 at the Department of Horticulture, West Pomeranian University of Technology in Szczecin, assessed the content of macro- and micronutrients in the fruit of selected Polish and Bulgarian cultivars of pepper collected at different stages of coloration development. The investigation included five Polish cultivars: Roberta, Marta Polka, Etiuda, Trapez and Cyklon and five Bulgarian cultivars: Bulgarski Ratung, Sivriya, Kurtovska Kapiya, Delikates and Dzuliunska Shipka. The study demonstrated...

In this study, the sorption characteristics of nicosulfuron herbicide in soils from different agricultural regions of Bosnia and Herzegovina, as well as factors influencing the sorption process, were evaluated. The analysis was performed using a batch equilibrium method. The obtained results showed that soils in Bosnia and Herzegovina are very versatile in terms of their characteristics. The Freundlich adsorption coefficient (Kf) coefficient ranged from 0.027 to 7.388, while the slope of the Freundlich isotherm (1/n) varied from 0.291 to 1.927. In soils with pH 4.31-7.60, 1/n...

A field campaign was conducted using six treatments under the summer rice-winter wheat cultivation system to evaluate the response of soil greenhouse gas (GHG) emissions to long-term differentiated fertilisation regimes. The treatments included control, phosphorus plus potassium, nitrogen only, nitrogen plus phosphorus (NP), nitrogen plus potassium, and NP plus potassium (NPK). Compared to the control, mineral fertilisation increased CH4 emissions during the rice season by 69% to 175%. Phosphorus amendment also enhanced seasonal CO2 emissions by 21%...

Several research groups have examined the effects of drought stress and heat stress on potato, but few investigations of the effects of combined drought-heat stress have been reported. Using five potato lines, the potato plants' responses to drought stress, heat stress, as well as combined drought-heat stress were studied, to get the insight in phenotypic shift due to abiotic stresses. The experiment was conducted as a growth room experimental under non-stress and abiotic stresses (drought, heat, and combined drought-heat) conditions. The results demonstrated that potato plants responded to the abiotic stresses by decreasing their plant height, leaf...

Glomalin released from arbuscular mycorrhizal fungi (AMF) has important roles in soil nutrient cycles, whereas contributing to glomalin-related soil protein (GRSP) fractions to soil nitrogen (N) is unknown. In this study, a two-chambered root-box that was divided into root chamber (root and mycorrhizal fungi hypha) and hypha chamber (free of the root) was used, and three AMF species including Diversispora epigaea, Paraglomus occultum, and Rhizoglomus intraradices were separately inoculated into the root chamber. Plant growth, soil total N, N content of purified GRSP fractions, and its contribution to soil total N, and leaf...
