“…In this region, the traditional livestock production causes the loss of 103,000 ha of forest each year, which are transformed into pasture areas (IDEAM, 2019). In many cases, those pasture areas are in some stage of degradation due to the absence of investments in soil and pasture management practices, such as fertilization, control of erosion, compaction, acidification, consequently soil organic matter (SOM) and biodiversity declines, thus affecting the productivity of the overall livestock system (Cherubin, Chavarro, & Silva, 2019; Nóbrega et al, 2017; Souza, Francelino, Costa, & Fernandes Filho, 2019).…”

Restoring soil carbon and chemical properties through silvopastoral adoption in the Colombian Amazon region

et al. 2020

Silvopastoral systems (SPS) have been widely implemented in the Colombian Amazon region to improve pastures involving a greater diversity of species, soil tillage, fertilization, and higher stocking rate, which can induce changes in soil properties and functions. This study aimed to evaluate soil chemical properties and carbon sequestration changes due to the transition from traditional pastures to silvopastoral systems. The study was conducted in the Colombian Amazon region, specifically in La Montañita and El Doncello Counties, in Caquetá, the second most important hotspot of deforestation in the entire Amazon basin. In each study site, we established a chronosequence consisting of three areas following the typical land‐use change at the region: (i) native vegetation, (ii) traditional pasture, and (iii) silvopastoral system. We found that agricultural practices involving liming and tillage, performed under the silvopastoral management, contributed to reducing soil active acidity and exchangeable acidity with soil pH increasing from 3.8 to 4.3 and H++Al3+ decreasing from 5.8 to 2.3 cmolc kg−1. These alterations favored increases in Ca2+ and Mg2+ contents mainly, increasing the base saturation from 17% in traditional pastures to 55% under silvopastoral systems. The synergic effect of the mix of grasses and trees under silvopastoral management improved soil micronutrient contents and modified soil C stocks in 20–30 cm layer. A rate of soil C accretion of 0.26 Mg ha−1 yr−1 for the 0–30 cm detected in silvopastoral systems suggests that its implementation could be a promising tool for C sequestration in tropical regions, capable of restoring soil functioning of degraded areas.

“…Concerning the above, a study found that rubber agroforestry systems with low diversification, present higher values of apparent density and resistance to penetration than more diversified agroforestry systems due to high abundance of roots mixed with a soft layer composed primarily of porous and rounded aggregates present in these systems (Cherubin et al, 2018). Likewise, an assessment of the effect of different land uses on soil quality suggests that rubber trees are the plant cover causing the smallest change in terms of soil quality (Moreira et al, 2011).…”

Soil Physical Quality and Relationship to Changes in Termite Community in Northwestern Colombian Amazon

Conversion from Amazon forest to low-management pasture or agriculture causes not only degradation of aboveground vegetation but also negative changes in soil properties and ecosystem services. This study aimed to evaluate the impact of physical soil degradation on termite community changes in three contrasting land uses (natural regeneration, rubber plantations, and silvopastoral systems). Soil physical quality was assessed through a set of physical variables, such as bulk density, porosity, soil macro-aggregation state, Visual Evaluation of Soil Structure (VESS) and penetration resistance, which were summarized in an overall synthetic indicator of physical quality. Besides, transects of 20 × 2 m were established in each land use; each transect was divided into four sections of 5 m to search and collect termites during 1 hour in each section; likewise, termites were collected from blocks of soil 25 × 25 × 10 cm (length, width, and depth, respectively) adapted from the Tropical Soil Biology and Fertility (TSBF) method. In total, 60 transects were evaluated, 20 in each land use. A total of 41 species were collected across the three land uses evaluated: natural regeneration presented 60% of the collected species (25 species), silvopastoral systems 53% (22 species), and rubber plantations 39% (16 species). Additionally, composition species from the silvopastoral, agroforestry systems, and natural regeneration were different, and a close association between these last land uses was observed. Soil physical characteristics showed significant variations between land uses. The rubber plantations presented lowest values of soil physical quality, while the natural regeneration showed high soil physical quality. These changes affected termite community and lead to changes in its composition with disproportionate loss of some species; however, there are some that can acclimate well to the decline in the soil physical quality.

“…Visual Soil Evaluation (VSE) techniques are procedures for visually assessing soil quality with emphasis on soil structural quality (Mueller et al, 2013). Their utility is well established for research (Cherubin et al 2019;Sasal et al, 2017;Pulido Moncada et al, 2014;Munkholm et al, 2013), soil management (Ball et al, 2017;McKenzie, 2013) and increasingly, knowledge transfer (Ball et al, 2018) due to procedures being suitable for a range of stakeholders (van Leeuwen et al 2018). Multiple techniques exist, varying in objective and methodology (Emmet-Booth et al, 2016), and can be loosely categorised by their depth of assessment (Ball et al, 2017) and the assessment approach taken, i.e.…”
