Allelopathy for weed control in acid solis with high organic matter

Abstract

[ES] La flora arvense es uno de los factores limitantes de la agricultura en climas templados húmedos. El control de la flora arvense es un reto actualmente porque las sociedades más avanzadas rechazan el uso de herbicidas sintéticos ya que suponen un riesgo para la salud humana y el medio ambiente. El control químico es peligroso para las personas y el mecánico es costoso y laborioso. Algunas de las nuevas alternativas para el control de la flora se basan en la alelopatía, que responde a los requisitos actuales de la sociedad. La alelopatía abre soluciones interesantes que pueden ser usadas en agricultura sostenible y ecológica. La solución alelopática no intenta la eliminación de las hierbas sino un control razonable que permita el cultivo con bajas poblaciones de hierbas para una agricultura sostenible. La alelopatía se puede hacer con cultivos alternativos o con residuos agroforestales. Algunas plantas con valor potencial para la alelopatía son las habas, pero también residuos forestales como las hojas verdes de eucalipto pueden ser aprovechadas. Estas soluciones son parciales y pueden ayudar a minimizar la aplicación de herbicidas, pero se requieren más investigaciones.

[EN] Weeds are one of the major limiting factors in agriculture under temperate humid conditions. Weed control faces a challenge nowadays because developed societies reject synthetic herbicides based on risks for health and environmental conservation. Chemical weed control is dangerous for humans and the environment, and mechanical weeding is too expensive and labor consuming. Some of the new alternatives for weed control are based on allelopathy, which meets some of the new requirements in modern societies. Allelopathy opens interesting solutions that can be used for a sustainable agriculture and even for organic agriculture. The allelopathy approach does not intend the elimination of weeds but the reasonable control of weed population at low levels that allow a sustainable agricultural production. Allelopathy can be made with alternative crops or with forest or agricultural residues. Some of the plants with allelopathy potential are leguminous such as faba been, but also forest residues as the green leaf of eucalyptus can be capitalized. These are partial solutions that can help in minimizing herbicide applications but further research is required.
