Foliar fertilization can help minimize losses due to hail damage – Canada
Active weather can result in various forms of physical damage to crops. And although severe hail damage is typically disastrous, crops can recover from minor to moderate hail injury if it’s managed correctly and in a timely manner.
Foliar fertilization with key nutrients, along with stress-tolerance technology can help hail-impacted crops repair damaged tissues. It’s crucial for crops to have easy access to the required nutrition in order to repair wound sites quickly and prevent pathogen entry through crop wounds.
Steps to hail-damage recovery.
Step 1 - Provide the nutrition needed for recovery
Potassium - essential for directing energy toward new growth and limiting production of reactive oxygen species.
Magnesium - rebuilding chlorophyll (energy factories)
Calcium and boron - rebuilding damaged tissue
Step 2 - Maximize crop-stress tolerance
When hail injury occurs, plant tissue is physically damaged. This not only reduces photosynthesis and energy production, it also makes the crop more vulnerable to pathogen attacks. A key aspect to hail recovery is quick and efficient repair of compromised tissue. Crops are able to do this if they have access to essential nutrients like potassium, magnesium, boron and calcium.
Potassium facilitates proper water and nutrient movement as well as providing pathogen-defense benefits. Kick-starting the repair of photosynthetic tissue requires the availability of sufficient magnesium. Calcium and boron are fundamental to cell-wall integrity, making them essential for rebuilding cells and repairing physical damage.
Alexin provides the energy, nutrition and boost of antioxidant production needed to increase photosynthesis, strengthen cell walls and improve abiotic stress tolerance. All of which are vital for successful hail-damage recovery.
