Purpose Application of Tithonia diversifolia leaves as organic fertilizer is common in most rural regions in Africa. There is usually time period for curing between preparation and application stage. However, this curing period leads to reduction in fertilizer efficiency. This study aimed at analyzing the change in functional groups, particle morphology, size and elemental composition […]
Purpose The purpose of this research was to evaluate the effectiveness of compositions based on the strains of microorganisms and intended for cow dung processing. Method Cow dung in an amount of 6 kg was placed into fermentation containers. To process the waste, we used microbial compositions. Sampling was performed on the 1st, 5th, 12th, […]
Purpose The current use of pesticides and chemical fertilizers harms the environment, alternative substitutions using organic materials are needed. One of them is utilizing the dairy industry sludge waste to become a Super Liquid Fertilizer (SLF). This study aimed to analyze the nutrient quality of SLF (a dairy industry sludge waste that was added to […]
Purpose Poultry litter (PL) and basalt rock powder (BRP) are raw materials highly produced in some Brazilian regions. The association of these products can generate greater added value for the agribusiness chain and be a sustainable source of fertilizer. Method The experiment consisted of an incubation trial over time for chemical characterization of the materials. […]
Purpose The objective of the study was to evaluate the application effects of different doses of onion residue mixed with bovine manure compost as an organic fertilizer on a hybrid Tetsukabuto squash crop cultivated in a field. Method The experimental design required randomly dividing blocks with three replicates. The experiments were designed with different dose […]
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 Due to the urgent need for sustainable agro-industrial waste management, a field experiment was conducted to evaluate the application of biosolids as organic fertilizer in a corn cultivation crop. In addition, to achieve food security, the study aimed to assess metals concentrations in soil and maize plants and enrichment factors (EF) for soils and […]
Purpose: It is known that the combination of bioprocesses can contribute to obtaining better results compared to those achieved by applying each process individually. Solid state fermentation of Vitis labrusca grape pomace was carried out using different saprotrophic fungi following a vermicomposting process. Method: A palatability test was performed to evaluate the permanence of Eisenia […]
Purpose Due to the pressures of conforming to environmental quality standards and the increased costs of mineral fertilizer importation, there is growing interest in the use of organic residues as fertilizers. To test the hypothesis that indicates the quantity of animal manure (AM) depends on the phosphorus (P) needs of the crops, an experiment was […]
Purpose Utilization of food waste as composting materials offers a sustainable solution to manage waste and reduce reliance on fertilizers. Method This study is focused on the efficiency of food waste compost and the effect of the addition of magnetite (Fe3O4) nanoparticles on the growth and heavy metals uptake by roselle (Hibiscus sabdarifa) for the […]
