Purpose: Floral waste, as a frequently overlooked resource for sustainable agriculture, can be harnessed to produce nutrient-rich soil amendments resulting in an enhancement of soil fertility and augment crop yields. This in turn can foster a circular economy, minimizing waste disposal and promoting a green economy. This study was aimed to explore the potential of […]
Purpose This study sought to investigate the effects of organic amendments on the degradation of hydrocarbons and vegetative properties of Zea mays grown in crude oil-contaminated wetland soils of the Niger Delta, Nigeria. Methods Two soil types were investigated, namely, fadama soil (oxisol) and swamp forest soil (utisol). For each soil type, 48 treatment cells […]
Purpose A huge number of sewer blockages are caused due to scum depositions. The scum waste from the kitchen wastewater can be converted into a resource by composting it. This study investigates the degradation of Grease scum or Fats, oils, and grease (FOG) waste from grease trap with Vegetable waste (VW) and Grass clipping waste […]
Purpose To evaluate the effect of palm bunch ash and mycorrhiza on soil properties and the performance of cucumber in Calabar. Method Factorial combination of five levels of palm bunch ash – PBA (0, 3, 6, 9 and 12 t/ha) and two mycorrhiza treatments (inoculated and non-inoculated), laid out in randomized complete block design (RCBD) […]
Purpose: In this study, we aim to investigate the suitability of five samples of compost extracted at various concentrations by testing for their phytotoxic response on Lactuca sativa L. We analyze relevant parameters with regards to the quality of the compost. By doing this, we hope to contribute to the attainability of clean, high-value organic […]
Purpose Chicken eggshell (ES) is a global biowaste product of poultry industry and an enriched source of calcium required for plant growth. Therefore, the present study has been carried out to assess the potentiality of the combination of ES with vermicompost (VC) and chicken feather protein hydrolysate (CFPH) on growth and yield improvement of Capsicum […]
Purpose: Wood ash is an important alternative source of inorganic potassium especially for farmers in areas with acidic soils. Method: The experiment was carried out in two phases. In the first phase, treatments consisted of the application of inorganic fertilizer sources (0 kgha-1, 130.44 kgha-1 of urea, and 300 kgha-1 of NPK of 20:10:10) and […]
Purpose: The use of sewage sludge associated with natural rock-based fertilizers can increase nutrient solubility and soil fertility. From this perspective, this study evaluated changes in the chemical soil attributes and the nutrient availability rate after the application of sewage sludge, natural phosphate, and elemental sulfur in soils with different clay contents. Method: The study […]
Purpose Reuse of treated wastewater (TWW) for irrigation can be an effective strategy in Morocco to overcome the pressure on freshwater resources. The M’zar wastewater plant is based on percolation infiltration treatment, allowing the purification of the wastewater of Agadir, and with its UV disinfection system, it is now possible to reuse this water for […]
Purpose The present study aims to evaluate the changes in parameters affecting the quality of vermicompost produced by the earthworm ‘Eisenia fetida‘ on different organic waste substrates using multivariate analysis, variance analysis, factor analysis and principal component analysis (PCA). Method A completely randomized design experiment was conducted with a 2 × 8 factorial arrangement of […]
