    Agrogeología del silicio : comprensión de los materiales geológicos y la formación de suelos para el fortalecimiento de la agricultura

    The characteristics of silicon fertilizers depend on aspects related to their raw materials, manufacturing process, physical presentation and chemical composition. It is evident that the application of silicon in agriculture generates significant benefits for plants by improving their resistance to biotic and abiotic stress, and enhancing the absorption of essential nutrients. These products are primarily derived from inorganic silicates, extracted in their mineral forms and processed to convert them into soluble forms, which, when added to the soil, become silicic acid, a bioavailable source for plants. The stability of silicon fertilizers is a critical aspect, and their effectiveness may vary depending on soil conditions and the type of crop. The edaphological heterogeneity in Colombia, with various soil types and climatic conditions, creates a favorable environment for the cultivation of silicon-accumulating plants, such as rice, sugarcane, corn, wheat, cassava, potatoes, soybeans, and sugar beets. Understanding the mechanisms of silicon absorption and transportation, the appropriate choice of fertilizers, and the edaphological variability in agricultural production are key factors in the effective application of silicon for the benefit of agriculture.
