Potassium supplying power of ten Akwa-Ibom State surface soils- a coastal oil producing state of Nigeria- were evaluated through a study of the forms and quantity-intensity relation of K in the soils. The total K contents ranged from 250-3,200 mg\/kg with the lowest value obtained from soils at Ikot-Osute coastal plain sands and the highest at obotme. The exchangeable K ranged from 0.13-0.46 me\/100g soil. The quantity-intensity isotherms derived from potassium potential studies were similar in all the soils. The activity ratio (AR.) ranged from 1.00-1.90\/1000 (m\/1)1\/2 and correlated significantly with exchangeable K (r = 0.809**). The labile K varied from 0.20-0.90 meg\/100g soil and correlated significantly with exchangeable K. Higher values of most of the parameters were observed in soils developed on mixed sandstones giving high K supplying power due to their high clay content which favours K adsorption and fixation in soils.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9786202268189\"\u003e\u003ch3\u003eNigeria\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9786202268189","offer_id":40147988643933,"sku":"9786202268189","price":35.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/a47db508-98c4-4298-9126-00f06b8ef411.jpg?v=1776235240","url":"https:\/\/shop.autorenwelt.de\/products\/potassium-supplying-power-of-selected-soils-of-akwa-ibom-state-von-sylvester-baye","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
