Abstrakt: The field study was conducted to determine association of soil physico-chemical properties with plant available macronutrients in Taluka Ghora Bari district Thatta. A total of 100 soil samples were collected from different sites at 0-15 and 15-30 cm depths. The results showed that 66% were heavy in texture, while 34% were light textured. Soils were alkaline (82%), moderately saline (81%), highly calcareous (97%) in nature, and low (66%) in organic matter. Majority of soil samples (77%) were poor in total nitrogen, 51% were deficient in available phosphorus while exchangeable potassium was adequate. Clay correlated negatively with P and K and positively with N, while sand correlated positively with K. The effect of lime content on NPK was found negative, while soil pH was correlated negatively with P and K. Organic matter correlated highly significantly with N, P and K. [ABSTRACT FROM AUTHOR]
