Abstract:

Our soil resource can be compared to a bank where continued withdrawal without repayment cannot continue indefinitely. As nutrients are removed by one crop and not replaced for subsequent crop production, yields will decrease accordingly. Accurate accounting of nutrient removal and replacement, crop production statistics, and soil analysis results will help the producer manage fertilizer applications. Macronutrients, micronutrients, pH and salinity were determined in soil samples from two cocoa farming towns in Assin North District in the Central Region of Ghana. Neutron Activation method was used for the elemental analysis. The pHs from both towns were within the acidic range and from both towns also salinity increased with depth. For the soil samples from Assin Akonfudi potassium concentration was the highest and molybdenum was the least in the soil. For the soil samples from Assin Bereku potassium recorded the highest concentration and molybdenum recorded the least concentration in the soil.
