2. Description of the SLM Technology
2.1 Short description of the Technology
Definition of the Technology:
El caldo sulfocalcico es una mezcla de azufre y cal, utilizado para prevenir las enfermedades causadas por hongos en las plantas. El caldo bordelés que contiene cobre y cal también previene las enfermedades en el cultivo de plantas frutales.
2.2 Detailed description of the Technology
Description:
El caldo sulfocalcico se elabora en medio barril metálico con 2 kilogramo de azufre y 1 kilogramo de cal en 12 litros de agua, 5 rajas de leña para mantener encendido el fogón y de esta manera hacer hervir el agua, una ves que el agua este hirviendo depositar el azufre y la cal al mismo tiempo, esto se hace en agua herviendo ya que el azufre no es soluble en agua a temperatura ambiente, esta preparación se realiza removiendo constantemente hasta lograr diluir todo lo solido que se forma en el agua hirviendo y el punto es cuando toma un color rojizo, se deja enfriar y se guarda en botellas preferiblemente de color oscuro, no se debe guardar por mas de tres meses. El caldo sulfocalcico es un producto que ayuda en la prevención de las enfermedades causadas por hongos en los cultivos de: café, arboles frutales y hortalizas, así mismo permite la incorporación de nutrientes al suelo que ayudan a mejorar el proceso de floración y frutificación de las plantas. Se requiere para la elaboración del sulfocalcico azufre, cal, medio barril metálico, para hacer el cocimiento ademas de botellas plásticas de color oscuro para preservar y dar un adecuado almacenamiento.
