| Abstract |
Rubber tree (Heveabrasiliensis) is a major importance economic crop in Thailand as it represents a substantial source of income for small holders. Increasing demand of rubber production, the rubber tree was expanding to the marginal area in northeast (NE) of Thailand which was sandy texture, low soil fertility and nutrient leaching which often resulting in low yield of production. The study of soil chemical properties and leaf nutrient contents in chronosequence of the rubber plantation in NE of Thailand are needed in order to efficient management of farmer’s fields. And increase rubber’s yield. In this study, a chronosequence of 5, 11 and 22 years old plantations were monitored with 3 replications in each age. The experimental design was randomized completely block design (RCBD). The experiment was located at Kranuan District, KhonKaen Province. Each soil sample was described in the field sampled for 2 depths to represent the average rooting depth of rubber (0-15 and 15-30 cm). For leaf sampling, the leaves were collected from 4-5 branches per tree. Then, soil and leaf samples were analyzed for basic soil and plant chemical properties. The results showed that there were significant differences for nitrogen, organic matter and potassium in rubber aged 22 compare to the other ages. The older age seem to provide more nitrogen, organic matter and potassium compare to the young rubber, However, no significant impact of the age of the plantations on other soil chemical properties (pH, EC, P, Ca, and Mg) was found. For rubber leaf nutrient, the nitrogen, potassium and calcium in (22 years) rubber tree plantation had higher content than others.
