Purpose The solubility of silica is a key parameter affecting its suitability as a rice fertilizer. Therefore, this study determined the effect of calcination temperature and duration on the physical composition of silica derived from rice husk ash. Method Rice husks were calcined at 100–900 °C for 15–120 min in an electric furnace. The solubility […]
Purpose Chicken feather protein hydrolysate (CFPH) has drawn a significant attention as a component/type of biofertilizer in recent years, because of the beneficial impact on the growth of the plant. The current study aims to evaluate the potential influence of the combination of CFPH with vermicompost (VC) on growth-promotion and yield improvement in tomato plants. […]
Purpose Soil salinity and sodicity are among the factors involved in soil degradation, especially in arid and semi-arid areas of the world. The use of modifiers, including organic matters, can be considered as an appropriate strategy to improve the fertility of saline-sodic soils. Method In this study, saline-sodic control soil was collected from Karaj and […]
Purpose The upsurge of vegetable oil production in Nigeria and the equally increasing concern for the environment which arises due to indiscriminate disposal of phytotoxic vegetable oil mill effluent in a less regulated country like Nigeria makes the re-use of the effluent for fertigation a suitable strategy for its disposal if the appropriate treatment technique is […]
Purpose Reuse of landfill leachate is an effective alternative for their nutrients to mitigate decrease in freshwater. On the other hand, the growth of vegetation in the final disposal areas provides many benefits such as improving the visual impact, controlling of hydric erosion, etc. The purpose of this work was to evaluate landfill leachate as […]
Purpose Anaerobic digestion produces renewable energy, biogas, from organic residues, but also digestate, a valuable organic fertiliser. Previous studies have indicated that digestate contains ample plant available nitrogen (N), but there are also concerns about greenhouse gas (GHG) emissions after application of digestates to soil. The aim of this study was to compare digestate and […]
Purpose Bangladesh is an agriculture-based country, where about 3 million ha is covered by groundwater sources for irrigation, but a significant portion of irrigation water is Arsenic contaminated. To produce Potato under Arsenic contaminated soil, an experiment was conducted to find out the effect of sawdust as an adsorbent to decontaminate Arsenic toxicity in soil. […]
Purpose Two field experiments were conducted to evaluate the effects of locally prepared biofertilizers (Jholmal 1 and Jholmal 2) on soil properties and chili yield (Capsicum annuum L.). Method The experimental site was in west-central Bhutan. The experiments were Randomized Complete Block Designs (RCBD) consisting of three treatments (cattle dung/ urine: Jholmal 1, cattle urine: […]
Purpose Thailand generates approximately 18 million tons of urban food waste per year, which is disposed of with municipal waste and largely goes to landfills. However, this approach not only takes up a large area but also causes environmental problems. The easiest way to manage food waste is by separating it at the source and […]
Purpose This study aimed to evaluate the biochemical characterization of solid state fermented maize (Zea mays) cob and its use in poultry feed production. Method Solid state fermentation was carried out at room temperature for 72 hours using Rhizopus oligosporus inoculum with a well prepared phosphate buffer (50 mM , pH 6). Results Results showed […]
