Foliar fertilization can help minimize the impact of frost damage

_____________________________________


Cold weather can result in various degrees of physical damage to crops. And although severe frost events can cause significant impact, crops can recover from minor to moderate frost injury if it’s managed correctly and in a timely manner. Foliar fertilization with key nutrients, along with stress-tolerance technology can help frost-impacted crops repair damaged tissues and replace nutrients lost due to cell death. It’s crucial for crops to have easy access to the required nutrition in order to repair damage quickly and effectively.


Steps to frost-damage recovery

Step 1 - Provide the necessary nutrition for recovery


Potassium - limits the production of reactive oxygen species and is essential for directing energy toward new growth.

Magnesium - rebuilding chlorophyll (energy factories)

Calcium and boron - rebuilding damaged tissue

Step 2 - Maximize crop-stress tolerance


When water freezes inside plant cells, ice crystals form, expand and then rupture cell walls. When the temperature warms up, the ice crystals melt and the punctured cells lose water and nutrients. This can result in nutrient deficiencies, reduced photosynthetic capacity and energy production or even cell death. A key aspect to 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 is a major nutrient lost in cell leakage. Foliar feeding with potassium maintains proper water relations and sugar 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 and cell membrane integrity making them essential to rebuilding cells and repairing physical damage caused by frost events.


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 frost-damage recovery.
