Fertilizantes
"El número de personas desnutridas en el mundo sigue siendo inaceptablemente alto, cerca de 925 millones. Los problemas de seguridad alimentaria mundial existen ahora y son especialmente preocupantes de cara al futuro, ya que se espera que la población mundial aumente en aproximadamente un 35 % en los próximos 40 años. La producción agrícola deberá aumentar de manera significativa para adaptarse a la población en aumento. Se espera que la mayor parte del incremento provenga de una mayor producción en las tierras agrícolas existentes (es decir, intensificación), aunque es probable que se necesiten algunas tierras agrícolas nuevas. Se puede aumentar el rendimiento de los cultivos y cerrar la brecha entre el rendimiento real y el alcanzable, mediante la implementación y el avance de numerosas prácticas y tecnologías, incluidas las prácticas de gestión de nutrientes y las tecnologías de fertilizantes. Una evaluación de estudios a largo plazo ha demostrado que el porcentaje promedio de rendimiento atribuible a los insumos de fertilizantes generalmente varió entre el 40 % y el 60 % en climas templados (EE. UU. e Inglaterra) y tendió a ser mucho mayor en los trópicos. A fin de cuentas, los fertilizantes inorgánicos desempeñan un papel fundamental en la seguridad alimentaria mundial, pero debe reconocerse que, en algunos sistemas, los rendimientos más altos son el resultado del uso de fuentes de nutrientes tanto orgánicos como inorgánicos. La adopción de los principios de las 4R (fuente de nutrientes adecuada a la tasa correcta, en el momento adecuado y en el lugar correcto) ayuda a garantizar el uso apropiado de los recursos de nutrientes y una productividad optimizada."
