Abstract
Leachate collected from soils to which rubber effluent was applied contained consistent levels of ammonium nitrogen (NH4-N) whereas the amount of NH4-N in leachate from fertiliser-treated soils fluctuated at times being significantly higher than those from effluent-treated soils. Leachate from effluent-treated soils had higher levels of potassium (K) magnesium (Mg) and calcium (Ca) compared to those from fertiliser-treated soils. The frequency of effluent application affected only the level of NH4-N in the leachate and application at a lower frequency produced leachate with lower concentrations. Soils treated with rubber effluent had higher nutrient contents than fertiliser-treated soils but rubber seedlings grown on fertiliser-treated soils had higher leaf nitrogen contents than those grown on effluent-treated soils. There was no significant difference in latex yield produced by the effluent-treated seedlings and the fertiliser-treated seedlings.
