These relationships deserve to be evaluated in order to develop a better management and conservation of the paramo ecosystem. This research was developed in three land uses were we estimated the carbon stored in the biomass above and below ground (Depths: 0 to 10 and 10 to 30 cm). 102 monitoring sites were installed distributed between land use types (30 pine plantations, 36 disturbed paramo and 36 undisturbed paramo) and at three elevation ranges 1) P1: 2800 - 3200 m. a. s. l., 2) P2: 3200 – 3500 m. a. s. l. 3) P3: > 3500. In the sampling sites aboveground biomass were calculated. Soil samples were taken to determine the organic carbon at two depths and the method of ignition was used. The results indicated that the higher levels of soil organic carbon are in the soil at higher altitudes. Larger amounts of organic carbon were found in paramo and forest plantations. This is attributed to bulk density and also changes in soil texture. It was concluded that the soil organic carbon associated with taxonomic variables and agricultural activities. KEYWORDS: PÁRAMO, IGNITION STOCKS, AND ORGANIC MATTERItem Alternativas Agroecológicas para el manejo del café (coffea arabica)(2012) Alulima Cornejo, Marco Vinicio; Neira Armas, EinsenhowerItem Alternativas al uso de bromuro de metilo en el cultivo de gypsophila paniculata L. Var. Million star. en el cantón Gualaceo(2014) Coronel Chumbi, Martha Verónica; Serrano Vicuña, Luis Francisco; Bermúdez, Fernando GerardoThe project aimed to search for the alternatives to substitute methyl bromide in the soil disinfection for the cultivation of Gypsophila paniculata L. The research took place in the province of Azuay, Gualaceo Village, specifically in ISPLANTS flower-growing, with the collaborations of the University of Cuenca, The United Nations Organization (UNIDO), the Ministry of Production (MIPRO) and the Association of Flowers Producers and Exporters from Ecuador (EXPOFLORES). The research was carried out on a plot of 967, 20 sm (square meters). A Randomly Design was applied (RD) with 6 treatments and 4 repetitions. For the Variant Analysis (ADEVA), the INFOSTAT and 22 SPSS program was used and the Turkey´s significance test to the 5%; the realized treatments were: (chemical + micro-organisms); biologic applying biological micro-organisms to the soil and the organic ones with the bio-solarization system. Four variables were evaluated: 1. Number of weeds at 30 days of transplantation, 2. Number of dead plants throughout the crop cycle, 3. Number of shoots per plant at 40 days of the pinch, 4. Number of total exportable stems and quality on weight of the stems in total. The most promissory alternative was the T0 treatment ((Agrocelhone) + (Ballus, Tricomix, Actimax, Biol)) because it got satisfactory results. In the economic analysis, it was determined that the treatment T5 (2 kg / m² of plant material + 0.5 kg / m gallinaza) is the most profitable alternative since it has a lower variable cost with a higher net profit.Item Alternativas de almacenamiento de maíz (Zea mays.L.) con miras a reducir el ataque de plagas en el período de post-cosecha(1994) Martínez R., Juan Pablo; Rivas Carrión, KléberItem Alternativas de control de la mosca de la fruta en manzana Anna.

However, the transition from wild plant to cultivation has brought with it several agronomic problems, including phytosanitary problems that significantly reduce the production of the plant. Among them are those caused by fungi of the genus Fusarium, which for their control the most used method has been chemical, however, the use of agrochemicals directly affects the quality of soil and water, generating limitations for producers and the environment, which is why more efficient and profitable alternatives have been sought, such as the use of antagonistic microorganisms to prevent and eradicate fungal diseases. For this reason, in the present research we experimented with alternative controls and a traditional one. The research consisted of four treatments, each treatment with 5 replications; giving a total of twenty experimental units, each with 5 yellow pitahaya stalks for a total of one hundred. The treatments consisted of drench type applications of solutions inoculated with Trichoderma and Bacillus subtilis plus a chemical treatment Carboxin (Vitavax) and a control treatment, on plants infected by Fusarium. The chemical treatment proved to be the most efficient in the control of Fusarium, since it showed a lower percentage in incidence and severity of the pathogen, followed by the alternative controls Trichoderma and Bacillus subtilis respectively, which proved to be more economical, but not more effective.Item Alternativas para el combate de Empoasca kraemeri en el cultivo de fréjol arbustivo en el Valle de Yunguilla(1998) Guillén Larrea, Fabián; Pozo Castro, JorgeItem Alternativas para el manejo de la fertilidad de los suelos amazónicos ecuatorianos bajo cultivo de pastos(2002) Castro Eras, Franklin Hernán; Pozo Castro, Jorge; Frometa, Enrique
