The profitability of beekeeping is generating interest in solving the many questions inherent in this technique, the low Scientific Technical support, poor circulation and lack of status and of the institutions involved in one way or another I have motivated to give an alternative solution in the control varroasis, ectoparasite bound to generate significant losses today in the world of beekeeping, all this today is associated requirements in product free of contamination, this effect in the present work and taking the technical implementation of Thymol, organic product known by beekeepers for its efficiency in controlling Varroa destructor Oudemans, a trial was carried out by applying organic products, such as Huamansamana and oregano extracts macerated in alcohol, in three doses 2%, 5%, 8%, these products were applied in two different sectors, industry and sector Poloponta Sabinal, both...

Este estudio se enfocó en evaluar los efectos de la inoculación de microorganismos benéficos en suelos degradados por la actividad agrícola en la subcuenca del Cumbaza, San Martín. Se emplearon factores de leguminosas A: Canavalia ensiformes + Crotalaria juncea, B: Vigna unguiculata + Cajanus cajan y AB: asociación de las 4, conjuntamente con tratamientos, T1(IM) inoculación microbiana , T2(IM+P) inoculación microbiana más fertilización fosfatada, T3 (IM+H) inoculación microbiana más humus de lombriz, T4 (NPK) fertilización inorgánica, y T5(SI) sin inoculación, en un diseño experimental de parcelas subdivididas en tres bloques (repeticiones). Se evaluó la actividad enzimática (fosfatasa y ureasa), respiración basal, biomasa microbiana y características fisicoquímicas del suelo en zonas Chirikyacu y Aucaloma. El factor AB promovió el incremento de biomasa microbiana,...

In the present work was evaluated the content of cadmium in soils, leaves, fresh almonds (testa and embryo), dried fermented almonds, cocoa liquor, and chocolate bars with 70% cocoa, two provinces (Bellavista and Huallaga), and 5 locations (3 in Bellavista and 2 in Huallaga) of the San Martín Region. The cadmium content was determined with an atomic absorption spectrophotometer, using a filtered sample obtained from 0.5 g of dry sample and 5 ml of perchloric nitric solution, after digestion; tests carried out in laboratories of the Universidad Nacional de San Martín (UNSM). The maximum values obtained for cadmium content (ppm) were: in soils, 0.960; in sheets 0.780; in testa and cotyledon 0.098; in fermented and dried almonds 0.075; in cocoa liquor, 0.210; in chocolate tablets with 70% cocoa 0.625. The correlation coefficient (R2) for fermented and dried almonds, indicates that there i...
