Jdm engine wholesale9/2/2023 Las enfermedades constituyen una de las principales limitaciones de la cantidad y calidad de la producción de los cultivos porque reducen la disponibilidad de los nutrientes, su absorción, distribución y utilización por la planta. Key words: mineral nutrition, plant diseases, beneficial elements. This article presents a review of the relationship between mineral nutrition and disease development and discusses the beneficial effects of silicon in crops, its mobility in soil, the process of assimilation through the roots and its influence on tolerance to fungal diseases. Many studies have suggested that Si activates the defense mechanisms of plants, but the exact nature of the interaction between this element and the biochemical pathways that direct resistance still remains unclear. Although not considered an essential nutrient for most plants, a lot of evidence shows the beneficial effects of nutrition with Si on growth, development and health of crops. Silicon (Si) is one of the most abundant elements in the lithosphere and most soils have considerable amounts.
