Abstract

This study was undertaken to evaluate the effect of varying age plantations of Eucalyptus tereticornis on soil properties in Kerala. Study area is Trivandrum Forest Division. Study sites were selected in Eucalyptus tereticornis plantations. Analysis were carried out for particle-size separates, soil pH, organic carbon, cation exchange capacity, and available N, P and K according to procedures in ASA (1965) and Jackson (1958) . Gravel contents were also determined. Conversion of natural vegetation to man-made forests with the management measures normally practiced today, and continued cropping of plantations has resulted in soil deterioration. The most apparent reasons for concern with regard to soil properties in varying are plantations of eucalypts are the sharp decline in organic carbon and nutrient levels so also the increase in the soil compaction in older plantations
