The potential use of waste-stream products for soil amelioration in peri-urban interface agricultural production systems.

Abstract

This review had an international rather than a country-specific focus although most of the examples cited were from developing countries. The review formed part of a strategy to develop and promote cost-effective techniques for recycling/processing organic waste-stream products (municipal waste, night soil and sewage sludge, poultry manures, and agroindustrial wastes from crop processing and livestock) for use as a fertilizer and contributed to the wider goal to increase productive potential by greater use of waste materials and recycling of resources. The information is given as a checklist to aid decision making.

Solid Waste Management and Recycling

“…• the cultivation of dumpsites (closed or operating) (Furedy and Ghosh, 1984;Drescher, 1994;Furedy, 2002); • the 'mining' of dumpsites for organic matter (see Rosenberg and Furedy, 1996: 72;Scheu and Bhattacharya, 1995;Nunan, 2000;Brook and Davila, 2000;Djabatey, 1996;Asomani-Boateng, 1999;Harris et al, 2001;Kiango and Amend, 2001); • the transportation of mixed solid waste to farms, where inorganics are largely removed before the waste is applied to soils (Lewcock, 1995;WASTE, 1998;IBSRAM, 2000;Nunan, 2001;Dulac, 2001); • on-farm co-composting of urban animal and farm wastes (which also applies to 'backyard farms') (Birley and Lock,1999:139;Nunan, 2001).…”

Studies on Heavy Metal Accumulation and Quality of Irish Potato (Solanum Tuberosum) Tubers Grown with Inorganic and Organic Fertilizers in Jos, Plateau State, Nigeria

“…Agriculture production contributes significantly to economic development in Nigeria. Among crops Irish potato (Solanum tuberosum L.) ranks fourth in the world in terms of economic importance (Harris et al, 2017). Developing countries account for 25% of the world potato production.…”

On The Goodness of Four Types of Organic Fertilizers Using the Split Plot Design and the Two-Way Block Design with Interactions

“…In addition, some compost contains other growth-promoting substances such as B vitamins, natural hormones and organic acids. Harris et al [33] said that compost that has been made from a variety of materials is likely to provide the best spectrum of nutrients. Lopez-Real [34] in his study, showed that market waste co-composted with saw dust improves crop yield considerably while Cross and Strauss [35] showed that soil nutrients is greatly improved with the use of urban waste.…”
