Recycling spent Pleurotus eryngii substrate supplemented with Tenebrio molitor feces for cultivation of Agrocybe chaxingu

Purpose In the industrialized production of mushrooms usually only one flush of fruitbody is harvested, so that nutrients and energy in the substrate is not fully exploited. In this study, the spent Pleurotus eryngii substrate was recycled for the cultivation of Agrocybe chaxingu under ambient temperature. Method Six formulae were tested: (1) Control: 98% spent […]

Soil chemical properties and growth response of Moringa oleifera to different sources and rates of organic and NPK fertilizers

Purpose The need for increasing production of Moringa oleifera in Nigeria can be achieved through adequate fertilization. This study investigated the effects of sources and rates of NPK (15:15:15) and compost on soil properties and productivity of Moringa at National Horticultural Research Institute, Ibadan, Nigeria. Methods NPK was applied at 30, 60, and 90 kg […]

The effect of municipal sewage sludge on the quality of soil and crops

Purpose To examine the effects of the application of composted sewage sludge fertilizer (commercially sold as Kala compost) and inorganic (NPK) fertilizers on soil quality and on two crops (radish and beans) irrigated using groundwater and sewage treated wastewater (TWW) for irrigation by measuring heavy metals in the soil and plants and other parameters such […]

Influence of composting and thermal processing on the survival of microbial pathogens and nutritional status of Nigeria sewage sludge

Purpose Sewage sludge samples from a water treatment plant in Nigeria were subjected to an in-vessel composting (using sawdust as a bulking agent) and thermal sludge processing to improve its quality for agricultural applications. Methods Treated samples were analyzed for physicochemical and microbiological properties using standard analytical and aerobic culture protocols. Results Microbiological analysis of […]

Carbon mineralization and carbon dioxide emission from organic matter added soil under different temperature regimes

Purpose Information on carbon dioxide (CO2) emission from different organic sources and their temperature sensitivity to decomposition is scarce in Bangladesh. Therefore, this study quantified the rates of CO2 emission and carbon (C) degradation constants from different organic material mixed soils at variable temperatures in two laboratory experiments. Methods The first experiment was conducted at […]

Bioconversion of organic solid wastes into biofortified compost using a microbial consortium

Purpose Urban municipal solid waste in India are 75–85% organic. Uncontrolled dumping of this waste is a major health concern. Degradation of organic waste by use of a microbial consortium is safe, efficient and economic. Therefore, this study was taken up to recycle the organic solid waste into effective compost using a microbial consortium. Methods […]

Enhancement in the productivity of ladies finger (Abelmoschus esculentus) with concomitant pest control by the vermicompost of the weed salvinia (Salvinia molesta, Mitchell)

Purpose In a novel attempt, vermicompost derived from an intransigent and noxious weed salvinia was assessed for its fertilizer value and pest repellent properties. Methods In outdoor experiments which simulated the way vegetables are cultivated by farmers, ladies finger (Abelmoschus esculentus) seeds were germinated and grown in soil supplemented with salvinia vermicompost at four levels: […]

Use of pineapple waste for production of decomposable pots

Purpose The aim of this research was to evaluate the suitability of pineapple waste for production of decomposable nursery pots. Methods The experiment was completely randomized, with three replicates and eighteen formula treatments. Treatments consisted of varying ratios of pineapple waste to binder, including 2:1, 1:0 (fresh pineapple waste), 1:1, 1:1.5, and 1:2; the textures […]

Optimization of laccase production and its application in delignification of biomass

Purpose Current research focuses on the biological delignification of biomass by microbial laccase which is an environmentally friendly process. Methods Various statistical approaches were designed for optimization of laccase production like Plackett–Burman design as well as response surface methodology (RSM). A laccase mediator system was designed for the delignification of saw dust which was molecularly […]

Evaluation of nineteen food wastes for essential and toxic elements

Purpose The study evaluates and provides an overview of the nutritional importance of 19 selected food wastes as aids in human/livestock/soil/plant health. Methods Nitric acid-digested extracts of food wastes belonging to four different classes (fruits, vegetables, oilseeds and beverages) were analysed for different elements in an inductively coupled plasma mass spectrometer. Results Our study recommends […]
