Abstract
In the Windward Islands, a considerable improvement in exchangeable potassium content of the soils is noted and high analysis for this nutrient is recorded for many recent leaf samples. A constant and somewhat alarming decrease in magnesium, often accompanied by a decrease in calcium, is recorded for both leaf and soil samples. There is an increasing incidence of magnesium deficiency in the area. The need for greater attention to the balance of nutrients when formulating fertilizer advice is suggested.
