Abstract: Nutrient depletion in the farm land areas has brought terrible devastation in some cropping areas of a country. There is no vegetation whatever, despite adequate rainfall and chemical fertilizers are now re-vegetating such areas. They have rapidly overtaken organic matter as a chief source of nutrients and expert opinion believes that such external nutrients source are the only way to sustain the food requirement of the population. If sustainability is to be maintained as the first priority, then other important components such as efficiency of input use, economic return and environmental protection can all be used appropriately as part of the sustainability phenomenon.
