Case Studies with Central Asian Soils

  • Kodoth Prabhakaran Nair


The chapter discusses, at length, the importance of the precise determination of Zinc buffer power in wheat cultivation in Central Asia (Turkey, in the wheat belt, Anatolia). The results clearly demonstrate the scientific inadequacy of the commonly used soil test for Zinc bio availability – the DTPA test – in the Anatolia region, and, unequivocally demonstrate how the buffer power concept has been able to enormously help the wheat farmers of the region with regard to Zinc fertilizer application, who have been wasting their monetary resources on unscientific fertilizer application, for example, as much as 100 kg ZnSO4/ha.
