Chemical Fertility of an Ozisol in Malaysia Planted to Cocoa as Affected by the Application of Ground Basalt and Rice Husk Compost
Oxisols are common in Malaysia. A study was conducted to determine the effects of ground basalt and/or rice husk compost application on an Oxisol planted to cocoa. Basalt application increased soil pH, with concomitant decrease of exchangeable Al. It also resulted in the increase of exchangeable Ca and Mg. Leaf K and P were within the sufficient range for cocoa growth. Rice husk compost applied at a rate below 20 t/ha was not able to supply enough N to the cocoa. Basalt is found to be an effective soil ameliorant, but it takes time to realize its positive effects.
