Interactions of soil amendments and complex fertilizers 1: effects on soil properties and nutrients uptake by cocoa seedlings (Theobroma cacao L.)

The effects of different soil amendments and complex fertilizers in a factorial combination on the growth of cocoa seedlings grown in poly bags of Serdang soil series were investigated. The soil amendments incorporated were ground magnesium limestone (GML) and Agrosil at rates of 7.3 g and 14 g per poly bag respectively. The other factors consisted of complex fertilizers that is 12:12:17:2 TE and 16:18:12:5 TE which wre applied at rates of 15 g and 10 g per poly bag respectively. Results indicated that Agrosil reduced organic C and N contents but increased availability of P Na and Ca in the soil Agrosil also induced symptoms similar to that of K and Mg deficiency. Better utilization of N P K Ca and Mg by the leaves were observed when complex fertilizers were used in conjunction with GML. However the Mg content in the leaves did not improve significantly. GML alone did not increase the uptake of macronutrients significantly. This experiment also indicated that the uptake of nutrients in the leaves can be improved through proper use of soil amendments in which GML has an advantage over Agrosil.

Abstract

The effects of different soil amendments and complex fertilizers in a factorial combination on the growth of cocoa seedlings grown in poly bags of Serdang soil series were investigated. The soil amendments incorporated were ground magnesium limestone (GML) and Agrosil at rates of 7.3 g and 14 g per poly bag respectively. The other factors consisted of complex fertilizers that is 12:12:17:2 TE and 16:18:12:5 TE which wre applied at rates of 15 g and 10 g per poly bag respectively. Results indicated that Agrosil reduced organic C and N contents but increased availability of P Na and Ca in the soil Agrosil also induced symptoms similar to that of K and Mg deficiency. Better utilization of N P K Ca and Mg by the leaves were observed when complex fertilizers were used in conjunction with GML. However the Mg content in the leaves did not improve significantly. GML alone did not increase the uptake of macronutrients significantly. This experiment also indicated that the uptake of nutrients in the leaves can be improved through proper use of soil amendments in which GML has an advantage over Agrosil.
