摘要
土壤是对生态系统可持续性具有重要意义的自然组成部分。在大多数情况下,山坡土壤条件的退化是由于管理不善,这降低了土壤生产力及其维持人类生命的能力。对2013年墨西哥普埃布拉市城郊代表性农业系统的沉积物产量和养分损失进行了评估,以加权这些沉积物的富集系数,从而确定产生较少肥力损失的农业系统。在玉米、玉米-南瓜和玉米-燕麦作物系统中设置了宽3米、长9米的划界地块,均匀坡度为9%。收集沉积物,测定有机质、氮、磷浓度,标记为NOM-021-SEMARNAT-2000。玉米的产沙量和径流量显著较高(分别为54.6 mm和37.9 Mg ha - 1),而玉米-南瓜地块的产沙量和径流量显著较低。侵蚀沉积物富集系数大多大于1,有机质富集系数最高。在农业系统中,沉积物的产生与有机质、氮和磷的损失有很强的相关性。结果表明,研究区目前的农作物管理有利于土壤退化。同样,所产生的结果是制定农业战略和减少墨西哥普埃布拉市城郊农村退化地区的重要基础。
Erosión y pérdida de nutrientes en diferentes sistemas agrícolas de una microcuenca en la zona periurbana de la ciudad de Puebla, México.
Soil is a natural component of great importance to ecosystem sustainability. Degradation of hillside soil conditions is due, in most cases, to poor management, which diminishes soil productivity and its ability to sustain human life. Production of sediment and nutrient loss during 2013 was evaluated in agricultural systems representative of the periurban zone of the city of Puebla, Mexico, to weight the enrichment coefficient of these sediments, and thus identify the agricultural system that generates less fertility loss. Delimited plots 3 m wide and 9 m long with a homogeneous slope of 9% were installed in maize, maize-squash and maize-oats crop systems. The sediments were collected, and concentrations of organic matter, nitrogen and phosphorus were determined, as marked by NOM-021-SEMARNAT-2000. Sediment yield and runoff were significantly higher in maize (54.6 mm and 37.9 Mg ha‑1, respectively) and lower in maize-squash plots. The enrichment coefficients of the eroded sediments were mostly higher than one, and organic matter had the highest coefficients. There was a strong correlation between sediment production and losses of organic matter, nitrogen and phosphorus in agricultural systems. The results obtained demonstrate that the current management of agricultural crops in the study area favors soil degradation. Likewise, the results generated are an important basis for establishing agricultural strategies and reducing degraded areas of the rural periurban area of the city of Puebla, Mexico.
