Purpose Silicate rock powders have been appointed as possible nutrient alternative sources which might enhance the agri‑ cultural sector sustainability. However, the application of those materials directly in soil presents as main limitations the low content and solubility of the mineral nutrient sources. In this perspective, the aim of the present study was to evaluate, […]
Purpose The objective of research was emphasized on the optimal conditions (initial pH and C/N ratio) for enhancing bioenergy from food waste by a two-stage fermentation process. Methods Bioenergy production from food waste was operated by mixed culture under thermophilic temperature in batch reactor. Thermophilic biohydrogen production was optimized in terms of initial pH (5.0–9.0) […]
Purpose This research aimed to study the adsorption of ammonium and nitrate by simply modifying the surface of the rice husk using slow pyrolysis and surfactants modifcation. Methods Rice husk biochar was prepared by slowly pyrolyzing at 500 °C, 2 h. The rice husk and its biochar were modifed by cetyltrimethylammonium bromide or sodium dodecylbenzenesulfonate. FTIR, BET […]
Purpose To study the direct efect on the frst mustard cropping and the residual efect of three kinds of vermicompost on the productivity of the second, third, fourth Pak-Coi mustard sequential cropping. Method A feld experiment was conducted for four sequential planting periods of mustard Pak-Coi in silty clay Inceptisol. The experiment used a factorial […]
Purpose Olive oil industry is a growing industrial sector in Mediterranean countries. Unfortunately, about 30–35% of total olive weight is discarded as olive pomace (OP), a highly environmental-polluting solid waste.OP is mostly used for composting and production of animal feed; nevertheless, the high oil content, phenolic compounds and fber contents in addition to its low […]
Purpose This study conducted to assess the presence of pharmaceuticals in soils and crops irrigated with treated wastewater in Oman. The study was aimed to evaluate the potential of plant uptake of four commonly used pharmaceuticals in Oman: amoxicillin, sulfamethoxazole, trimethoprim and ibuprofen by radish (Raphanus raphanistrum subsp. sativius) in soil culture. Methods Radish (Raphanus […]
Purpose Improving the nutritional value of rice straw by microbial inoculants and some physical treatments for animal feeding during dry seasons. Methods Diferent microbial inoculants and some physical treatments were used to improve the nutritional value of rice straw. Rice straw was divided into moist straw, soaked straw for 24 h without pasteurization and soaked for […]
Purpose In the present study, efect of earthworm-processed MSW was seen on biochemical, physiological, and yield responses of Abelmoschus esculentus L. Methods Plants were grown on diferent amendment ratios of municipal solid waste vermicompost (MSWVC). Pot experiments were conducted by mixing MSWVC at 0, 20, 40, 60, 80, and 100% ratios to the agricultural soil. […]
Purpose This study aimed to achieve successful composting and aeration rate and to optimize the carbon:nitrogen (C:N) ratio to provide favourable conditions for the process. In the current experiment, investigation were made on variations in physico–chemical properties, i.e., temperature, ammonia and carbon dioxide emissions, pH, electrical conductivity (EC), organic matter (OM) and seed germination index […]
Purpose In a novel approach, certain organic wastes byproducts of agro industries were assessed for their ability to support maize growth and Zn bioavailability in maize grain. Methods In a feld experiment, maize (Zea mays) was supplemented with farm yard manure (FYM), press mud (PM), fsheries manure (FM), and slaughter house waste (SHW) in combination […]
