This episode of "Cutting the Curve" focuses on the critical role of calcium in crop health and nutrient uptake. Agronomic expert Tommy Roach and farmer Kelly Garrett discuss how calcium, often misclassified and overlooked in row crop management, is essential for cell strength, nitrogen uptake, and overall yield. Despite soil containing adequate levels, calcium's availability and mobility to the plant are limited due to its double positive charge and mass flow dependency, especially under drought conditions. Garrett outlines a comprehensive multi-pass application strategy using both in-furrow and foliar methods, often up to five times per season, emphasizing the use of calcium acetate and proper nutrient pairing - such as boron - to enhance uptake. They advocate for reallocating nutrient budgets to focus on micronutrient balance, supported by real-world results from SAP and tissue testing showing increased ROI and yield improvements.

Cardiac Cowboys
The heart was always off-limits to surgeons. Cutting into it spelled instant death for the patient. That is, until a ragtag group of doctors scattered across the Midwest and Texas decided to throw out the rule book. Working in makeshift laboratories and home garages, using medical devices made from scavenged machine parts and beer tubes, these men and women invented the field of open heart surgery. Odds are, someone you know is alive because of them. So why has history left them behind? Presented by Chris Pine, CARDIAC COWBOYS tells the gripping true story behind the birth of heart surgery, and the young, Greatest Generation doctors who made it happen. For years, they competed and feuded, racing to be the first, the best, and the most prolific. Some appeared on the cover of Time Magazine, operated on kings and advised presidents. Others ended up disgraced, penniless, and convicted of felonies. Together, they ignited a revolution in medicine, and changed the world.
