Purpose This study aimed to verify the effects of the application of carnauba waste on the biological attributes, organic carbon content, and hydrothermal regime of soil. Method The experiment was performed in randomized blocks with six treatments and four replicates. The treatments were as follows: (1) NPK (recommended dose of synthetic fertilizers: 100:180:86 kg ha-1 […]
Purpose: Recent trends in land use and the effects of climate change resulted in the decline of organic matter content of the soils. Since crop management systems play an important role in soil carbon sequestration, therefore our aim was to determine the long-term effects of different organic fertilizers on soil respiration and its driving factors. […]
Purpose Organic matter has significant effects on phosphorus (P) retention in soil. Applying vermicompost (VC) as an organic amendment is an eco-friendly approach to increase sustainability in agriculture. There is a high potential of P loss by leaching or surface runoff from coarse-textured soils. Column leaching experiments were conducted to determine the effect of VC […]
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 (i) To evaluate the efficacy of spinach in dry powdered and liquid form as a sustainable substitute for chemical fertilizers; (ii) To analyze and compare the morphological and yield-related parameters of Solanum melongena plants using spinach powder and compost as compared to the control treatment. Method In a pot experiment, Solanum melongena seeds were […]
Purpose This study assessed the fertilizing potential and environmental impacts of recycling the blood meal powder (BMP) produced in the abattoir as an organic fertilizer in agriculture. Method In this study, a 70-day laboratory incubation experiment was conducted using a clayey calcareous soil to study the effects of adding abattoir BMP at three rates (1.5, […]
Purpose: A study was carried out during the 2021 dry season and 2022 rainy season to evaluate the differences in the performance, fruit longevity, mineral, and vitamin C compositions of two varieties of pepper (Capsicum chinense) cultivated using different organic amendments and inorganic fertilizer as a check. Poultry manure (PM), Tithonia diversifolia (TD), cattle manure […]
Purpose: Application of organic manures, along with fertilizers, is important to maintain soil fertility to achieve higher productivity. In reality, the farmers apply organic manures and fertilizers in different proportions and quantities depending on their availability and purchasing power of farmers. Organic manures also help to enhance soil carbon stocks and soil biological activities. Hence, […]
Purpose: Degraded soils are associated with low organic matter and nutrient contents, which limit their productive capacity to produce sufficient food. Improving the productivity of degraded soils is key to achieving sustainable food production and tackling global food crises. Method: A study was carried out between September 2021 to March 2022 in a greenhouse at the University […]
Purpose: A study was conducted to transform bovine blood, a slaughterhouse by-product, into an organic source of nitrogen, which is otherwise disposed of through sewer systems only to pollute the nearby water bodies. Method: The annual blood production in the Khulna City Corporation (KCC) slaughterhouses was estimated, blood samples were collected, and blood meals were […]
Purpose: Poor management of chicken litter by the poultry industry has caused many environmental issues. Biochar’s unique characteristics make poultry litter-to-biochar conversion an intriguing management option thus, could be utilized as an organic fertilizer for plant nutrients. In this research, poultry litter was converted into biochar, which offers a range of possible applications, including analyzing […]
Purpose: One of the primary wastes of the sugar industry that has the potential to be converted into fertilizer is filter cake. Organomineral fertilizer is proposed as a promising approach. Therefore, this research evaluated the efficiency of various filter cake-based organomineral formulations for sweet maize growth under different fertilization rates. Method: The treatments comprised of […]
Purpose Waste disposal poses serious environmental challenges to mankind. This precipitated the quest for an eco-friendly waste management approach to minimize the challenges wastes pose to the ecosystem and proffer alternative use for these wastes. Method A field study was carried out at the University of Nigeria Nsukka Teaching and Research Farm to investigate the […]
Purpose Soil nutrient depletion and possible degradation have been highlighted as key reasons for lower crop yields in Nigeria. The present study was aimed to assess the effect of Trichoderma harzianum on the bioconversion of different solid organic wastes into compost and its application on cucumber. Method The treatments were 3 levels of T. harzianum inoculum (0, 5 and 10 ml) and 4 types of solid […]
