Abstract: Esta investigación se planteó como objetivo evaluar el efecto de diversas prácticas de manejo del suelo sobre la macrofauna edáfica del distrito de Soritor- Moyobamba, para lo cual se utilizó el método de muestreo propuesto por el “Tropical Soil Biology and Fertility” (TSBF). La densidad total más abundante de la macrofauna edáfica se registró, en forma decreciente, bosque secundario (7 363,2 ind/m2), cafetal (7 152,0 ind/m2), cacaotal (6 937,6 ind/m2) y maíz (3 038,4 ind/m2). Las categorías taxonómicas de mayor concentración se registraron en el cacaotal, con la familia Formicidae (5 100,8 ind.m-2) y orden Coleóptera (828,8 ind.m-2), la cantidad mínima se registró en café y cacao, orden Zygentoma (3,2 ind.m-2) y orden Orthoptera (3,2 ind.m-2). El análisis de componentes principales posibilitó la visualización del efecto de cuatro usos de suelo sobre la macrofauna edáfica, se diferencian tres patrones: donde el cultivo de Cacao presenta valores mayores de Oligochaetas, Formicidae, Isóptera, Araneae e Isópoda; en el cultivo de maíz y bosque secundario la mayor abundancia de: Lepidóptera, Heteróptera, Blattodea y Homóptera; en el cultivo de Café presenta valores mayores de: Coleóptera y Chilopoda. La macrofauna edáfica se ve influenciada por la Materia Orgánica, en el suelo del cultivo de maíz se registra un pH medianamente ácido y con menor porcentaje de Materia Orgánica (MO 13,8%), los cultivos de cacao, café y el bosque secundario son medianamente básicos, y el mayor porcentaje de Materia Orgánica se registra en el bosque secundario (MO 46,0%), los valores de nitrógeno son los deseables en los cuatro usos de suelo y se relacionan con el porcentaje de Materia Orgánica, finalmente, el suelo del cultivo de maíz, mostró valores fisicoquímicos y de macrofauna edáfica menores, en relación a los otros usos de suelo estudiados.
The objective of this research was to evaluate the effect of different soil management practices on the edaphic macrofauna of the Soritor-Moyobamba district, using the sampling method proposed by the Tropical Soil Biology and Fertility (TSBF). The most abundant total density of edaphic macrofauna was recorded, in decreasing order, secondary forest (7 363.2 ind/m2), coffee plantation (7 152.0 ind/m2), cacao plantation (6 937.6 ind/m2) and corn (3 038.4 ind/m2). The taxonomic categories with the highest concentration were recorded in cacao plantations, with the family Formicidae (5 100.8 ind.m-2) and order Coleoptera (828.8 ind.m-2), the lowest amount was recorded in coffee and cocoa, order Zygentoma (3.2 ind.m-2) and order Orthoptera (3.2 ind.m-2). The principal component analysis allowed the visualization of the effect of four land uses on the edaphic macrofauna, three patterns are differentiated: where the Cacao crop presents higher values of Oligochaetes, Formicidae, Isoptera, Araneae and Isopoda; the corn crop and secondary forest the highest abundance of: Lepidoptera, Heteroptera, Blattodea and Homoptera; the cultivation of Coffee presents higher values of: Coleoptera and Chilopoda. The edaphic macrofauna is influenced by the organic matter, the soil of the corn crop shows a medium acid pH and a lower percentage of organic matter (OM 13.8%), the cocoa, coffee and secondary forest crops are medium basic, and the highest percentage of organic matter is recorded in the secondary forest (OM 46.0%), nitrogen values are satisfactory in the four soil uses and are related to the percentage of organic matter. Finally, the corn soil showed lower physicochemical and edaphic macrofauna values in relation to the other soil uses studied.
