| dc.description | Green manures have positive factors in the soil, improving its physical, chemical and biological properties, especially in soils that are heavily compacted and eroded by conventional agriculture. The information obtained was detailed through the technique of analysis, synthesis and summary, with the objective of highlighting specific information on the effects of the incorporation of green manures in degraded soils in Ecuador. From the above detailed, it was determined that the most common causes affecting soil degradation are: deforestation, use of chemical products to fertilize cereal crops, climate change, heavy agricultural machinery, insufficient irrigation, overgrazing and depletion of soil organic matter. Green manures refer to the use of any plant in rotation, succession or combination of crops with crops incorporated into the soil or left on the surface as manure to preserve and improve their physical, chemical and biological properties. Legumes can be used as green manures, each of which is beneficial for increasing soil fertility and the productivity of related crops. Green manures can be used in various ways to improve degraded soils such as: green manure in association with annual crops, green manures associated with perennial crops, green manure with strips and/or mixture (legume mixture), green manure with perennial plants, green manure in crop rotation with annual crops and green manure as a cover crop. Plants used as green manure are beneficial for biological activity because they provide the soil with organic matter, which is a determining factor for microbial activity and provides a source of energy for microbial development | es_ES |

| dc.description.abstract | Los abonos verdes poseen factores positivos en el suelo mejorando sus propiedades físicas, químicas y biológicas, especialmente en los suelos que están fuertemente compactados y erosionados por efecto de la agricultura convencional. La información obtenida fue detallada mediante la técnica de análisis, síntesis y resumen, con el objetivo con el objetivo de resaltar la información específica sobre los efectos de la incorporación de abonos verdes en los suelos degradados del Ecuador. Por lo anteriormente detallado se determinó que las causas que afectan a la degradación del suelo son más comunes: deforestación, uso de productos químicos para la fertilizar de cultivos de cereales, cambio climático, maquinaria agrícola pesada, riego insuficiente, pastoreo excesivo y agotamiento de la materia orgánica del suelo. Los abonos verdes se refieren al uso de cualquier planta en rotación, sucesión o combinación de cultivos con cultivos incorporados al suelo o dejados en la superficie como abono para preservar y mejorar sus propiedades físicas, químicas y biológicas. Las leguminosas pueden usarse como abono verde, en donde cada una de las cuales son beneficiosas para aumentar la fertilidad del suelo y la productividad de los cultivos relacionados. Los abonos verdes se pueden utilizar de diversas maneras para mejorar los suelos degradados tales como: Abono verde en asociación con cultivos anuales, abonos verdes asociados a cultivos perennes, abono verde con franjas y/o mezcla (mezcla de leguminosas), abono verde con plantas perennes, abono verde en rotación de cultivos con cultivos anuales y abono verde como cobertura. Las plantas utilizadas como abono verde son beneficiosas para la actividad biológica porque aportan al suelo materia orgánica, que es un factor determinante para la actividad microbiana y proporciona una fuente de energía para el desarrollo microbiano. | es_ES |
