Abstract
AbstractRecent advances have enabled solid waste byproducts to effective soil amendment in order to minimize the use of inorganic fertilizers and increase crop yields to provide food for a high-population world. This review aims to summarize the essential nutrients required for crop production, the ability of nutrient supply of solid waste byproducts as soil conditioners, and its impacts on plant growth and soil properties. This paper analyzes the sources of plant nutrients, functions, symptoms of deficiency, and corrective measures. This review analyzed the byproducts of municipal solid waste compost, waste biomass, biochar, farmyard manure, press-mud molasses, vinasses, olive mill waste, spent mushroom compost and fly ash (FA), cow dung vermicomposting with FA, FA mixed with biochar, sewage sludge-FA mixture, fiber sludge, sewage sludge, bauxite residue, poultry waste to determine their ability to supply nutrients, affecting plant growth and soil properties significantly. This review also discusses the challenges associated with solid waste byproducts used in agricultural soil amendment on the environment and human health and possible future strategies to be adopted. Overall, this review provides insights to farmers about the use of solid waste byproducts as soil conditioners for the enrichment of essential nutrients and soil properties in farming soil.
