Un AV/CC es...

“Una especie de planta, a menudo pero no siempre leguminosa, ya sea un árbol, arbusto, vid o planta rastrera, que un agricultor utiliza para uno o varios fines, al menos uno de los cuales es el de mantener o mejorar la fertilidad del suelo o controlar las malezas.” Roland Bunch

Los abonos verdes son los que se utilizan con el objetivo principal de mejorar la fertilidad del suelo.

Los cultivos de cobertura son aquellos cultivos que se utilizan con el objetivo principal de controlar las malezas.

Los beneficios potenciales de los AV/CC incluyen:

  • aumento de la materia orgánica del suelo a través de la producción de biomasa
  • aumento del ciclo de nutrientes
  • fijación biológica de nitrógeno (cultivos de leguminosas) que agrega nitrógeno al suelo
  • mantener o aumentar la vida del suelo cubriendo el suelo como "mantillo vivo"
    • temperatura del suelo más baja
    • ayudar a retener la humedad del suelo
  • aumentar la resiliencia del suelo
    • estructura del suelo
    • fertilidad del suelo
    • retención de la humedad
  • disminuir insumos
    • posibilidad de usar semillas disponibles localmente
    • disminución del 25-40 % en el uso de productos químicos
  • mano de obra reducida (durante el crecimiento)
  • generación de ingresos potencial
    • forraje para animales
    • comida humana (legumbres)

Las posibles desventajas incluyen

  • Resultados lentos: los beneficios de un cultivo AV/CC de primer año a menudo no se ven hasta la próxima temporada de crecimiento
  • Cuando se intercalan, puede haber competencia entre cultivos
  • A menos que un AV/CC también produzca alimentos o ingresos, no siempre se acepta fácilmente


  1. Los AVCC son cultivos de rápido crecimiento que cubren y protegen el suelo, y se dejan como mantillo o se incorporan durante el arado para enriquecer el suelo. Las legumbres son priorizadas por su capacidad para fijar nitrógeno. Pueden establecerse a partir de semillas, pero algunas echan raíces...
