“…In addition to the earthworms, arthropods that constitute the edaphic macrofauna [87,132,133] are also of great interest. Millipedes (Myriapoda: Diplopoda) fragment and feed on organic wastes and excrete low C/N ratio feces (2.2% N) producing the millicompost [134][135][136].…”

This work summarizes information about organic nitrogen (N) in the agricultural system. The organic N forms in soils have been studied by identifying and quantifying the released organic compounds when soils are acid treated at high temperature, in which the following organic N fractions are obtained: hydrolyzable total N, subdivided into hydrolyzable NH 4 + -N, amino sugars-N, amino acids-N, and unidentified-N and acid insoluble N, a fraction that remains associated with soil minerals after acid hydrolysis. Nitrogen mineralization and immobilization are biochemical processes in nature. This chapter summarizes how these processes occur in the agricultural system. Then, soluble organic nitrogen (SON), volatilization and denitrification processes, and biological nitrogen fixation (BNF) as a key component of the nitrogen cycle and how it makes N available to plants are also discussed. Finally, we discuss the use of organic fertilizers as N source to satisfy the worldwide demand for organic foods produced without synthetic inputs.

“…La riqueza de especies está en relación positiva con la complejidad vegetal; la cual determina una mayor cantidad de microhábitats y de recursos disponibles (Rivas y Schoereder, 2007). Suárez et al (2019) evaluaron la ocurrencia de macrofauna en suelos cafeteros con diferentes sistemas de manejo, en total, 17.109 individuos fueron registrados, siendo el grupo Oligochaeta el más representativo, independientemente del sistema de producción de café. En cuanto al índice de Shannon Weaver (H), se observaron diferencias significativas entre sistemas en Consacá, La Florida y Sandoná, entre profundidades en La Florida y Sandoná.…”

La edafofauna es un indicador biológico de la fertilidad del suelo. Conocer su diversidad permite establecer relaciones funcionales con éste y tomar decisiones para establecer prácticas de conservación. El objetivo de este trabajo fue evaluar la riqueza (Ri), abundancia relativa (AR) y diversidad de la edafofauna en cuatro municipios del departamento de Nariño La Unión, Sandoná, Consaca y La Florida. Los muestreos se hicieron en tres altitudes que se tomaron como repeticiones. En bosques secundarios y cultivos de café se registraron la Ri y la AR en mantillo, entre 10 y 20 cm y entre 20 a 30 cm de profundidad. En Consacá se registraron un total de 19.836 individuos de 24 órdenes, de los cuales el 37,6% correspondieron a bosque y el 62,4% a café. La Florida mostró un total de 13.980 individuos de 16 órdenes de los cuales el 41,3% se ubicó en el bosque y el 58,7% en café. En La Unión se encontraron 6.935 individuos en 17 órdenes, donde el 64,2% se ubicaron en el bosque y el 35,8% en café. El número de individuos en Sandoná fue de 10.436, de los cuales, el 10,7% se ubicaron en el bosque y el 89,3% en café. En los bosques se presentaron mayores valores de diversidad que en los cultivos café. La interacción sistemas x profundidades no fue significativa, a excepción de los índices de Sahnnon-Weaver y Simpson en Sandoná. Los órdenes Hymenoptera, Acari y Coleóptera fueron los más prevalentes con diferencias en Ri y AR entre bosque y café.

Mountain agroecosystems in Latin America provide multiple ecosystem functions (EFs) and products from global to local scales, particularly for the rural communities who depend on them. Agroforestry has been proposed as a climate‐smart farming strategy throughout much of the region to help conserve biodiversity and enhance multiple EFs, especially in mountainous regions. However, large‐scale synthesis on the potential of agroforestry across Latin America is lacking. To understand the potential impacts of agroforestry at the continental level, we conducted a meta‐analysis examining the effects of agroforestry on biological activity and diversity (BIAD) and multiple EFs across mountain agroecosystems of Latin America. A total of 78 studies were selected based on a formalized literature search in the Web of Science. We analysed differences between (i) silvoarable systems versus cropland, (ii) silvopastoral systems versus pastureland, and (iii) agroforestry versus forest systems, based on response ratios. Response ratios were further used to understand how climate type, precipitation and soil properties (texture) influence key EFs (carbon sequestration, nutrient provision, erosion control, yield production) and BIAD in agroforestry systems. Results revealed that BIAD and EFs related to carbon sequestration and nutrient provisioning were generally higher in agroforestry systems (silvopastoral and silvoarable) compared to croplands and pasturelands without trees. However, the impacts of agroforestry systems on crop yields varied depending on the system considered (i.e., coffee vs. cereals), while forest systems generally provided greater levels of BIAD and EFs than agroforestry systems. Further analysis demonstrated that the impacts of agroforestry systems on BIAD and EFs depend greatly on climate type, soil, and precipitation. For example, silvoarable systems appear to generate the greatest benefits in arid or tropical climates, on sandier soils, and under lower precipitation regimes. Overall, our findings highlight the widespread potential of agroforestry systems to BIAD and multiple EFs across montane regions of Latin America.
