Assessment of the nutrient status of coastal marine sand (Bris) peninsular Malaysia by pot experiment using stylosanthes guianensis

Tham Kah Cheng and P.C Kerridge

Abstract

Pot experiments were undertaken to assess the nutrient status of the Baging,Rompin and Jambu Series soils of the 'bris' complex of Peninsular Malaysia. The legume Stylosanthes guianensis cv. Schofield was used as test plant. Major responses occured to P, K, S and Cu on the three soils, to Ca on the Baging and Jambu Series, and to B on the Jambu Series. Lesser responses occurred to B and Mo on the Baging and Rompin Series. There was a small but significant response to magnesium and boron on the Jambu Series. R esponses to P and K were changed to toxicity by heavy applications. The Rompin Series had a higher fertility status than the Baging and Jambu Series. Growth on the Jambu Series remained relatively poor even after application of deficient nutrients.
