Nutrition Management at Critical Points of Influence

445 Aufrufe

Veröffentlicht am

John Kempf discusses how to reach the maximum genetic capability of your crop by recognizing critical points of influence. All crops have cycles during which either vegetative or reproductive energy is dominant in the plant. At the peak moment of each cycle, and again when the cycle switches from vegetative to reproductive, plants enter a critical window of time at which the correct support is paramount for yields and quality.

In this deck, learn about these critical points of influence, how to observe their occurrence in crops, and how to influence outcomes by applying nutrition and other inputs differently at each critical point. See the full presentation at https://youtu.be/hUYwX9FlcPY.

Nutrition Management at Critical Points of Influence

  1. 1. NUTRITION MANAGEMENT AT CRITICAL POINTS OF INFLUENCE A Webinar Hosted by AEA Featuring John Kempf
  2. 2. Critical Points of Influence Male | Female Expansion | Contraction Vegetative | Reproductive Growth occurs in cycles of alternating dominance. Critical Points of Influence occur when the hormone balance shifts from reproductive dominance to vegetative dominance.
