Resumen
Las plantaciones forestales cumplen con una función en bien de la protección ambiental. Es una alternativa de beneficio social y económico. La fertilización de las plántulas es necesaria para el crecimiento aéreo y radial, aumento de reserva de nutrientes en los tejidos, resistencia a sequías, bajas temperaturas, enfermedades y acelera el crecimiento inicial de la plantación. En el presente estudio, se evaluó el efecto de dos bioles de elaboración artesanal de uso agrícola, los dos bioles tuvieron como base indistintamente efluente de cerdo y suero de leche. Este trabajo se hizo con el propósito de generar nueva información referente a su efecto en el desarrollo vegetativo de especies forestales Hieronyma alchorneoides y Terminalia amazonia a nivel de vivero, estudiando el comportamiento de nutrientes en su contenido foliar y en el suelo comparando su efecto a diferentes diluciones en las plántulas. Los parámetros evaluados en campo fueron: altura, diámetro basal y número de hojas. El experimento tuvo una duración de 11 semanas. El efecto de los tratamientos sobre el diámetro basal difirió dependiendo de la especie forestal. Para H. alchornoideas, el tratamiento T3 (cerdo 15 %) tuvo el mayor crecimiento del diámetro basal (2.85). Para ambas especies, las plántulas bajo los tratamientos T1, T2, T4 y T5 no presentaron diferencias significativas en parámetros de altura y número de hojas. El pH alcanzado en el tratamiento T3 (pH = 4.87) provocó un efecto positivo en H. alchorneoides, con una mejor asimilación de nutrientes reflejado en el mayor diámetro basal. Los análisis de laboratorio mostraron una mayor concentración de Fe (46 % y 70 %) y Mn (34 % y 55 %) en los tejidos vegetales de H. alchornoides y T. amazonia, respectivamente. La absorción de Mn y Fe pudo ser por medio de los nódulos o moteados de Mn / Fe que a menudo existen en los suelos del trópico húmedo.
Forest plantations play a role for the sake of environmental protection. It is an alternative of social and economic benefit. Seedling fertilization is necessary for aerial and radial growth, increased tissue nutrient reserve, resistance to drought, low temperatures, and diseases and accelerates the initial growth of the plantation. In the present study, the effect of two artisanal agricultural bioles was evaluated, the two bioles were based indistinctly effluent of pig and buttermilk. This work was done with the purpose of generating new information regarding its effect on the vegetative development of forest species Hieronyma alchorneoides and Terminalia amazonia at the nursery level, studying the behavior of nutrients in their foliar content and in the soil, comparing their effect to different dilutions in the seedlings. The parameters evaluated in the field were: height, basal diameter and number of leaves, and samples were sent to the laboratory for foliar and soil analyzes. The experiment lasted 11 weeks. The effect of the treatments on the basal diameter differed depending on the forest species, for H. alchornoideas, the treatment T3 (pig 15%) had the highest growth of the basal diameter (2.85). For both species, the seedlings under the treatments T1, T2, T4 and T5 did not present significant differences in parameters of height and number of leaves. The pH reached in the treatment T3 (pH = 4.87) caused a positive effect in H. alchorneoides, with a better assimilation of nutrients reflected in the larger basal diameter. Laboratory analyzes showed a higher concentration of Fe (46 % and 70 %) and Mn (34 % and 55 %) in the plant tissues of H. alchornoides and T. amazonia, respectively. The absorption of Mn and Fe could be by means of the nodules or mottles of Mn / Fe that often exist in the soils of the humid tropics.
