Exceso de radiación solar: qué debemos medir, entender y corregir – Dr. Carlos Castillo

In the fields, losses creep in slowly. First, a flower that doesn't set fruit, then a bud that doesn't fully develop, and later, a fruit that doesn't fill out. Then, a root that silently stops working. And finally, when the scales speak, everyone starts looking for someone to blame. The variety. The irrigation. The product. The consultant. The weather. The operator. Bad luck, which in agriculture always has a full schedule. But sometimes the problem was there from the beginning. In this episode of Agronauta, Dr. Carlos Castillo brings up a variable that Mexican agriculture still views with too much confidence and too little measurement: excessive solar radiation. We're not talking about heat as a sensation. We're talking about energy entering the system. Watts per square meter. Ultraviolet light. Soil and substrate accumulating heat. Roots that stop absorbing nutrients. Stomata that close. Photosynthesis that declines. Functional calcium and carbohydrates that no longer reach where they should. The plant doesn't improvise. It responds. And when radiation exceeds what the crop can handle, the response appears in flowering, fruit set, quality, and yield. This is the first part of a conversation divided into two episodes. In this installment, we discuss the physical and physiological phenomenon. In the second, we delve into the uncomfortable territory of agronomic basics: irrigation, drainage, roots, nutrition, mathematics, artificial intelligence, and common sense.

Because measuring data isn't very useful if we still don't understand what the plant is telling us.
