Macrofaunal composition in four plantain cropping systems in the municipalities of Armenia, Calarcá, and Circasia in Colombia was evaluated by measuring species richness, abundance, biomass, and variation in these parameters in relation to altitude and cropping system at 33 farms. The DPSIR (Driver-Pressure-State-Impact-Response) model was used to evaluate the impacts of management practices on crops and their repercussions for edaphic fauna. Fourteen orders, three classes, and eight families of macrofauna were identified. The results indicate that type of cropping system influences the composition of edaphic communities, mainly through the altitudinal gradient. Fifteen species of earthworms were found, seven exotic and eight native. The greatest number of species (12) was found in systems consisting of plantains associated with coffee (AC), followed by the traditional system (TA) with 10, plantain trees (AA) with nine, and monoculture (MONO) with eight species, of which the most abundant was Pontoscolex corethrurus. In our findings, it was possible to differentiate plantain cultivation systems according to the type of management practice and the intensity and frequency of application of agrochemicals by farmers on farms. The DPSIR framework permitted differentiation among cropping systems, visualizing agroecosystems that tolerate the presence of accompanying vegetation. Variables that exert pressure and provide options for differentiating the systems were also identified. DPSIR facilitates the understanding of cropping systems and has great potential for use in agroecosystem planning in rural areas.

海拔和车前草栽培系统对哥伦比亚咖啡地区土壤无脊椎动物的不同影响

通过测量33个农场的物种丰富度,丰度,生物量以及这些参数相对于海拔和耕作系统的变化,评估了哥伦比亚亚美尼亚,卡拉拉和切尔西亚的四个大蕉种植系统中的大型动物组成。DPSIR(驱动程序-压力-状态-影响-响应)模型用于评估管理措施对农作物的影响及其对食用动物的影响。确定了十四种,三类和八类大型动物。结果表明,耕作制度的类型主要通过海拔梯度影响土壤群落的组成。发现了15种species,其中7种是外来的,还有8种是本地的。在由与咖啡(AC)相关的车前草组成的系统中发现了最多的物种(12),Pontoscolex corethrurus。在我们的发现中,可以根据管理实践的类型以及农民在农场上使用农药的强度和频率来区分车前草栽培系统。DPSIR框架允许区分种植系统,可视化能够容忍伴随植被存在的农业生态系统。还确定了施加压力并提供差异化​​系统选项的变量。DPSIR促进了对种植系统的理解,并在农村地区的农业生态系统规划中具有巨大的潜力。
