Esta es la historia de un productor de cerezo en el valle de Colchagua durante la temporada
2024. No hay nombre, pero s\u00ed hay n\u00fameros. 18 hect\u00e1reas de cereza Santina y Lapins en
plena floraci\u00f3n. Temperatura al atardecer: 8\u00b0C, sin se\u00f1ales evidentes de riesgo. Pron\u00f3stico
de la app del celular: m\u00ednima de 4\u00b0C para esa noche. Sin sistema de monitoreo clim\u00e1tico
agr\u00edcola propio, ese productor hubiera dormido tranquilo.<\/p>


Con la estaci\u00f3n meteorol\u00f3gica agr\u00edcola de Globalmet instalada en su predio, la historia fue
diferente. A las 2:17 de la madrugada, el sistema detect\u00f3 que la temperatura en el huerto
hab\u00eda ca\u00eddo a 2,3\u00b0C y que el punto de roc\u00edo indicaba condiciones de alta probabilidad de
helada radiativa para las horas siguientes. La alerta lleg\u00f3 al WhatsApp del productor en
tiempo real.<\/p>


El productor se levant\u00f3, activ\u00f3 el sistema de aspersores anti-helada del sector de cerezo
m\u00e1s expuesto \u2014la quebrada norte del predio\u2014 y encendi\u00f3 los calefactores en el sector de
ladera. A las 5:30 de la madrugada, la temperatura en el huerto toc\u00f3 -1,8\u00b0C y se mantuvo
por 40 minutos. El agua de los aspersores form\u00f3 una capa de hielo sobre los brotes que los
aisl\u00f3 del fr\u00edo. Los calefactores mantuvieron el sector de ladera sobre 0\u00b0C.<\/p>


Al amanecer, los sectores monitoreados y protegidos presentaron da\u00f1o m\u00ednimo: menos del
3% de brotes afectados. Un predio vecino sin sistema de monitoreo ni protecci\u00f3n activa
\u2014que recibi\u00f3 exactamente las mismas condiciones clim\u00e1ticas\u2014 report\u00f3 da\u00f1o del 65% en
sus cerezos Santina, que estaban en plena floraci\u00f3n.<\/p>


En t\u00e9rminos econ\u00f3micos, la diferencia fue de aproximadamente 80 a 90 millones de pesos
en fruta salvada, en una sola noche. El costo del sistema de monitoreo de Globalmet para
esa temporada: menos del 2% de esa cifra.<\/p>


La alerta de helada para cultivos de Globalmet no es un servicio gen\u00e9rico. Est\u00e1 calibrada
para el microclima espec\u00edfico del predio, con umbrales ajustados al estado fenol\u00f3gico del
cultivo en ese momento \u2014que en plena floraci\u00f3n de cerezo es de apenas -0,5\u00b0C de
temperatura efectiva sobre los brotes abiertos. No a la temperatura del sector, sino a la
temperatura efectiva que est\u00e1 sintiendo la flor.<\/p>


Dos horas de anticipaci\u00f3n. Un WhatsApp. Ochenta millones de pesos salvados.
Eso es lo que hace el monitoreo clim\u00e1tico agr\u00edcola cuando est\u00e1 bien implementado.<\/p>\n
