Hidroponia

HIDROPONIA

La posibilidad de cultivar plantas sin tierra ya fue admitida en el pasado (1699) por Woodward, pero solo en los últimos 60 años ha adquirido gran importancia, por las proyecciones que tiene sobre la industria alimenticia.

Se entiende el "cultivo sin tierra" al método que provee los alimentos que requieren las plantas para su perfecto desarrollo por intermedio de una solución sintética de agua y sales minerales, en contraposición de su vía natural que es la tierra.

El cultivo de las  plantas sin suelo se desarrolló a partir de investigaciones llevadas a cabo para determinar que sustancias hacían crecer a las plantas y la composición de ellas.

 A comienzos de los años treinta, científicos de la Universidad de California, pusieron los ensayos de nutrición vegetal a escala comercial, denominando “Hidropónico” a este sistema de cultivo, palabra derivada de las griegas hydro (agua) y ponos (labor, trabajo), es decir literalmente “trabajo en agua”.

 Los cultivos hidropónicos o hidroponía pueden ser definidos como la técnica del cultivo de las plantas sin utilizar el suelo, usando un medio inerte, al cual se añade una solución de nutrientes que contiene todos los elementos esenciales vitales por la planta para su normal desarrollo. Puesto que muchos de estos métodos hidropónicos emplean algún tipo de medio de cultivo se les denomina a  menudo “cultivo sin suelo”, mientras que el cultivo solamente en agua sería el verdadero
