Foliar applied Micronutrients Nutrients enhance the ability of a crop to use the nutrients in the soil

TRANSIENT NUTRIENT DEFICIENCY

• The specific demand of a nutrient during reproductive growth or periods of peak demand.

• Occurrence– Environmental– Artificial

Transient Nutrient DeficiencyIn Crops

• Environmental– Temperature – Moisture– Transition

between vegetative growth and reproductive growth

• Artificial– Soil Amendment– Genetics ??

• Adaptation• New Varieties

Genetics• Non native plant

– Do we know how to grow it ??
