Abstract:The loss of mineral elements due to latex export can be a major threat to sustainable management of cultivated ecosystems. In this study, we monitored the loss of mineral elements in the latex of rubber of rubber trees (clone PR107, 28 years old) monthly for a period of one year under five tapping systems (S/2↓d/2 (ck)，S/2↓ d/3+ET2.0 %，S/2↓d/4+ET2.5%，S/2↓d/5+ET3.0%，S/2↓d/6+ET3.5 %). We obtained three main results: (1) Whatever the intensity of the tapping system, the concentration of mineral elements in the latex was: N>K>P>Mg>Ca; this constant ranking was attributed to the specific characteristics of each mineral element and also to their physiological functions in rubber trees. (2) With increased ethylene stimulation or tapping frequency the concentration of nutrients trended to decrease, while the amount of latex increased. We also observed that losses of mineral elements increased with an increase in the intensity of tapping (frequency or stimulation). (3) The monthly fluctuation in latex production and mineral elements exported were linked with environmental factors (mainly monthly average temperature and precipitation) and agricultural soil management (chemical fertilization).
