Comparing soil nutrient depletion in typical urban, peri-urban and rural farming systems in Ghana por Drechsel, Pay

“…In the land constrained urban vegetable system the costs of nutrient mining can best be assessed through their replacement costs via poultry manure or mineral fertilizer. Additional off-site costs of the vegetable system might be balanced through the fertilizer value of the water (for irrigation) and appears in general marginal in comparison with water pollution through the urban run-off.…”
