Potassium, the forgotten nutrient in West Asia and North Africa
1997
Krauss, A. (IPI, Basel (Switzerland))
Increasing demand for food and fiber from a restricted area of cultivable land in the West Asia-North Africa (WANA) region is contrasted by a considerable imbalance in fertilizer use, both in quantity and quality. The imbalance centers around potassium; its present use lags increasingly behind the removal with the harvested crop. In addition, the imbalance between the major nutrients, nitrogen and potassium in particular, is an obstacle for further yield and quality development as required by a steadily growing population. The consequences of continuing fertilizer imbalance can be seen in declining soil fertility due to soil mining, increasing susceptibility of crops to stress situations and in environmental problems
