La roca fosfórica es un producto obtenido de minas y del procesamiento metalúrgico subsiguiente de los minerales fosfatados. En realidad, se denomina roca fosfórica a nivel comercial a unos 300 fosfatos de diferentes calidades que se conocen en el mundo.<\/p>\r\n<\/div>\r\n<\/div>\r\n\r\n

La roca fosfórica es considerada como un producto natural<\/strong>. Siguiendo esta característica, es posible utilizarlo en agricultura orgánica o ecológica.<\/p>\r\n\r\n

Mejor aprovechamiento de los recursos.<\/strong> Algunas fuentes de roca fosfórica no pasan el proceso industrial de fabricación de fertilizantes, pero si pueden ser aplicados de manera directa al suelo.<\/p>\r\n\r\n

Pueden ser mejores fuentes de fósforo.<\/strong> Bajo circunstancias especiales, las rocas fosfóricas reactivas pueden ser más eficientes que los fertilizantes fosfatados solubles en base a la recuperación del fósforo por las plantas.<\/p>\r\n\r\n

Bajo costo.<\/strong> Por todo el proceso que implica la elaboración de fertilizantes fosfatados, lógicamente la roca fosfórica y sobre todo las locales, son normalmente los productos más económicos.<\/p>\r\n\r\n

Las rocas fosfóricas contienen trazas de otros elementos. <\/strong>Las rocas fosfóricas son compuestos extremadamente variables y complejos, de manera que, muchas veces aparte de aportar fósforo también liberan otros nutrimentos presentes en la roca.<\/p>\r\n<\/div>\r\n\r\n

Son una alternativa como arranque de los cultivos.<\/strong> Se refiere principalmente a las rocas de reactividad media a alta y especialmente cuando son aplicadas a suelos ácidos tropicales altamente edafizados. En estos suelos, las rocas funcionan como un producto de “arranque” dando un efecto potencial sobre el crecimiento inicial de las plantas y el rendimiento. Además, aporta calcio intercambiable y reduce los efectos de toxicidad del aluminio.<\/p>\r\n\r\n

En definitiva, todas estas propiedades de las rocas fosfóricas ayudan en la mejora de la fertilidad de los suelos y al control de su degradación, en particular para evitar el empobrecimiento de los nutrimentos.<\/p>\r\n\r\n

Desafortunadamente, así como se han mostrado ventajas de este producto, también existen desventajas. A continuación se enlistan las principales:<\/p>\r\n<\/div>\r\n<\/div>\r\n\r\n

Desafortunadamente, así como se han mostrado ventajas de este producto, también existen desventajas. A continuación se enlistan las principales:<\/p>\r\n\r\n

    \r\n\t
  • No todas las fuentes de roca fosfórica pueden ser aplicadas de manera directa con éxito, muchas necesitan de evaluaciones previas, sobre todo aquellas de reactividad media a baja.<\/li>\r\n\t
  • Es necesario caracterizar cada fuente de roca fosfórica para evaluar bajo qué circunstancias  y tipos de suelos pueden ser altamente efectivas.<\/li>\r\n\t
  • Carece de un sistema bien definido para evaluar la eficiencia agronómica de su uso.<\/li>\r\n\t
  • Tienen composición química extremadamente variable y también pueden contener metales pesados y otros elementos que pueden ser dañinos.<\/li>\r\n<\/ul>\r\n\r\n

    La roca fosfórica es un producto obtenido de minas y del procesamiento metalúrgico subsiguiente de los minerales fosfatados. En realidad, se denomina roca fosfórica a nivel comercial a unos 300 fosfatos de diferentes calidades que se conocen en el mundo.<\/p>\r\n<\/div>\r\n<\/div>\r\n\r\n

    La roca fosfórica es considerada como un producto natural<\/strong>. Siguiendo esta característica, es posible utilizarlo en agricultura orgánica o ecológica.<\/p>\r\n\r\n

    Mejor aprovechamiento de los recursos.<\/strong> Algunas fuentes de roca fosfórica no pasan el proceso industrial de fabricación de fertilizantes, pero si pueden ser aplicados de manera directa al suelo.<\/p>\r\n\r\n

    Pueden ser mejores fuentes de fósforo.<\/strong> Bajo circunstancias especiales, las rocas fosfóricas reactivas pueden ser más eficientes que los fertilizantes fosfatados solubles en base a la recuperación del fósforo por las plantas.<\/p>\r\n\r\n

    Bajo costo.<\/strong> Por todo el proceso que implica la elaboración de fertilizantes fosfatados, lógicamente la roca fosfórica y sobre todo las locales, son normalmente los productos más económicos.<\/p>\r\n\r\n

    Las rocas fosfóricas contienen trazas de otros elementos. <\/strong>Las rocas fosfóricas son compuestos extremadamente variables y complejos, de manera que, muchas veces aparte de aportar fósforo también liberan otros nutrimentos presentes en la roca.<\/p>\r\n<\/div>\r\n\r\n

    Son una alternativa como arranque de los cultivos.<\/strong> Se refiere principalmente a las rocas de reactividad media a alta y especialmente cuando son aplicadas a suelos ácidos tropicales altamente edafizados. En estos suelos, las rocas funcionan como un producto de “arranque” dando un efecto potencial sobre el crecimiento inicial de las plantas y el rendimiento. Además, aporta calcio intercambiable y reduce los efectos de toxicidad del aluminio.<\/p>\r\n\r\n

    En definitiva, todas estas propiedades de las rocas fosfóricas ayudan en la mejora de la fertilidad de los suelos y al control de su degradación, en particular para evitar el empobrecimiento de los nutrimentos.<\/p>\r\n\r\n

    Desafortunadamente, así como se han mostrado ventajas de este producto, también existen desventajas. A continuación se enlistan las principales:<\/p>\r\n<\/div>\r\n<\/div>\r\n\r\n

    • No todas las fuentes de roca fosfórica pueden ser aplicadas de manera directa con éxito, muchas necesitan de evaluaciones previas, sobre todo aquellas de reactividad media a baja.<\/li>\r\n\t
    • Es necesario caracterizar cada fuente de roca fosfórica para evaluar bajo qué circunstancias  y tipos de suelos pueden ser altamente efectivas.<\/li>\r\n\t
    • Carece de un sistema bien definido para evaluar la eficiencia agronómica de su uso.<\/li>\r\n\t
    • Tienen composición química extremadamente variable y también pueden contener metales pesados y otros elementos que pueden ser dañinos.<\/li>\r\n<\/ul>\r\n\r\n

Efectividad agronómica relativa (EAR) de varias rocas fosfóricas (diferente solubilidad) en el rendimiento de tres cultivos sucesivos de frijol cultivados en un Andisol de Colombia (Chien, 2003). La EAR se calcula por comparación con el SFT.
