บทคัดย่อ (EN): Hevea brasiliensis, the prime source of natural rubber was introduced into India in 1873 and has been commercially cultivated since 1902 with the aim of establishing an assured source of important industrial raw material. In the beginning rubber plantations were raised mostly in newly cleared forests rich in plant nutrients. Most of the plantations in India are now in the second or third replanting cycle. To ensure optimum growth and yield and to protect sustainability of the system, maintenance of soil fertility through regular application of fertilizers is very important. Rubber is cultivated mainly in ultisols. They have high aluminum, low pH, iron and manganese toxicity, high P fixation, low molybdenum availability, low base saturation, extensive soil erosion and low microbial activity. Application of organic manures can greatly help in minimizing these productivity constraints. Keeping this in view a field experiment was initiated at our Central experimental station at Chethackal. The study comprised of four treatments viz. T1 (control), T2 (Rubber Board‘s recommendations), T3 (household compost @6 Kg /plant and T4 (compost @ 3Kg/plant plus high analysis fertilizer). There was no significant difference between compost and straight fertilizer treatments on the girth of trees when the two were used as nutrient carriers. Applications of composted household waste have proved to enrich the soil as evident from significant increase in organic carbon, phosphorus, available calcium, available iron and available zinc. The Girth of the trees were significantly correlated with soil solution Mn2+, Zn2+ and Cu2+ .The average soil solution activity were 3.59 X10-19, 1.44X10-5, 5.3X10-3 moles L-1 for Zn2+, Cu2+ and Mn2+ respectively. The concentration of Zn2+ was under saturated with respect to all the major zinc bearing minerals namely, smithsonite (ZnCO3), Zincite (ZnO), Willeminite(Zn2SiO4) and Frankinite (ZnFe2O4). Speciation studies with Zn prove the occurrence of ZnSO4o, ZnNO3+, ZnH2PO4+, ZnCl+, ZnCl42- in soil solution. These solution can further reduce the activity of Zn2+ and its subsequent availability to plants. Cu2+ was under saturated with respect to common minerals like Azurite (Cu3(OH)2(CO3)2), Tenorite (CuO), Malachite (Cu2(OH)2CO3) and Cupric ferrite (CuFe2O4). Hence these important Cu bearing minerals would have been lost by the process of weathering under high temperature and high rainfall conditions existing in the soils supporting Heavea brasiliensis. The aqueous activity of Cu2+ was estimated and was above that of Cu(OH)2o,CuOH+,Cu2(OH)22+, Cu(OH)3- and Cu(OH)42-. Mn2+ was oversaturated with respect to minerals Pyrolusite (â-MnO2), Manganite (”-MnOOH), bixbyite (Mn2O3), Birnessite (W MnO1.8) and Nustite (‹-MnOOH).The Mn2+ ion activity was above all other species (MnCl+,MnHCO3+, MnCO30, MnCl20) These chemical equalibria in soil shows compost treatments improved the bioavailable forms of Zinc and Copper in soil solution because the mineral forms were unstable and already leached out of the soil, nevertheless there was sufficient manganese from inorganic phase of the soil. Therefore addition of organic manure play a significant role in suppying copper and zinc nutrients in highly weathered soils in which Hevea brasilinsis is grown. About 1.15 lakh tones of urban wastes are produced each day in India of which 55% is biodegradable and can be used for land application.
