In this brief promotional video, John Kempf introduces Croptix's new same‑day leaf nutrient testing service for citrus and cotton. He explains the sampling protocol—collecting 30 new and 30 old leaves, scanning each leaf’s barcode after cleaning—and notes that results are delivered almost instantly. Using the same‑day results, he applied foliar corrections for calcium, manganese, and iron. The video concludes with an invitation to bring leaves to the upcoming citrus show in Fort Pierce for a free demonstration, encouraging viewers to comment “demo” for more information.
