Total and available molybdenum in some soils under rubber and their effect on Hevea
1992
Lim, T. S. | Lau, C. H.
Total and available molybdenum in nine major soil series in Peninsular Malaysia were determined. Total Mo in the soils varied from 1.13 mg/kg to 10.53 mg/kg while available Mo ranged from 155 mg/kg to 721 mg/kg soil. Among the soils, the marine days of the Selangor series soil and the basaltic Kuantan series soil have the highest total Mo content. Within the soil profiles, the Ap horizons appeared to have higher total and available Mo. Application of different levels of sodium molybdate to rubber seedlings grown in the glasshouse failed to induce any visual Mo toxicity symptom in the plants although dry matter yield declined at levels beyond 0.120 kg sodium molybdate/ha. Liming at rates of 2000 kg and 2800 kg ground magnesium limestone/ha enhanced the availability of Mo in the sandy Holyrood series soil. However, this effect could be marred by the rapid leaching loss of the nutrient.
