Hot conditions in the prairies often coincide with crops gearing up for flowering. During this reproductive stage, the crop has an increasing demand for boron. Unfortunately, boron is immobile in the plant and cannot be stripped from vegetative tissues to fulfill the transient peak of demand of the flowers.
Boron is a key nutrient to successful pollination. When the conditions become hot and dry or hot with a high level of relative humidity, boron translocation becomes jeopardized. This can lead to a poor extension of the pollen tubes resulting in misses in the pods. We often hear about ‘heat blast’ or ‘pod abortion’, which a direct consequence of boron shortage at flowering time. Heat also shortens the flowering period and affect the activity of the pollinators
So, what can you do? Beat the heat with boron!
