Abstract
Soil, water and plant leaf samples were collected for irrigated potatoes growing on 21 farms in Barka area. Soils on all the farms belonged to Entisols except one Aridisols. The soils were coarse textured, alkaline in reaction, highly calcareous and were saline (EC > 4 dS/m) on 48% of the farms. Exceptionally low organic matter in all samples revealed a universal deficiency of N on these soils. Both available P and available K were deficient in 90% of the samples. Boron, Fe and Cu were adequate in all the samples. But there was a widespread Zn and Mn deficiency. Zinc was < 0.8 mg/kg in 76% of the samples and Mn was < 1 mg/kg in 81% of the samples
