Summary

A survey of citrus groves was conducted by analysing leaf and soil samples from the main citrus growing areas of the island. The leaf data, evaluated by comparing them with the California leaf analysis standards for assessing the nutrient status of citrus leaves, indicated that the California standards are of limited value in attempting to assess the nutritional status of citrus in Trinidad, particularly with reference to the elements zinc and magnesium. The possibility of using soil analyses as an index to the mineral nutrition of citrus is worthy of consideration. Although symptoms of zinc and magnesium deficiencies had often been observed, these elements had not been given the attention they deserved in the regular fertilizer programmes.
