Organic C was optimum in soils at Vittal and Peechi due to green leaf application. Bray P-1, P was adequate in soils at Vittal, Peechi, Mohitnagar andKahikuchi, because of P fertilization. Exchangeable K2O was sufficient in soils at Hirehalli. Peechi, Mohitnagar and Kahikuchi as a result of addition of muriate of potash. Application of fertilizer-N increased acidity and decreased exchangeable K and Ca content of soils at Vittal, Peechi, Mohitnagar and Kahikuchi. N content of leaf appeared to be rather low, whereas K was high. Leaf-P was low in samples from Vittal and Hirehalli but satisfactory at Peechi, Mohitnagar and Kahikuchi. Ca content of leaf was above the average value in samples from all the centres except that of Peechi.enEffects of manuring on the nutrients contents of soil and leaf in arecanutArticle
