APAZA-CONDORI, Emma Eva; MAMANI-PATI, Francisco  and  SAINZ-MENDOZA, Humberto. Composting system for waste treatment coca leaf with the addition of three biological activators in the Experimental Center Kallutaca. J. Selva Andina Biosph. [online]. 2015, vol.3, n.2, pp.75-85. ISSN 2308-3867.

The objective of this study was to evaluate the composting process waste coca leaf with the addition of three biological activators (yogurt, whey and yeast). This work was carried out Kallutaca Experimental Center, Biofertilizers module Career Agricultural Engineering at the Public University of El Alto, La Paz municipality of Laja. Posed treatments were: T1 (+ Yogurt Coca wastes); T2 (Coca wastes + whey); T3 (Coca wastes + yeast) and T4 (Control). The design was completely randomized with 4 treatments and 3 repetitions. The values in N are classified medium and high levels the quantities of P, K are classified as middle levels. The value obtained 7.9 pH, EC 12950 µS/cm and 61% organic matter belong to treatment T1. The decomposition time was a period of 105 days corresponds to treatment T3.

Keywords : Compost; biological activator; coca waste.
