Optimizing Irrigation and Fertigation Scheduling with Leaf VPD Monitoring

What’s Leaf Vapor Pressure Deficit (VPD)?
Leaf VPD is essential for understanding how plants manage water and nutrient intake, measuring the difference between the moisture inside the leaf and the surrounding air. Maintaining the right VPD helps ensure that your plants lose just the right amount of water through transpiration, creating an optimal balance for nutrient and water uptake during both irrigation and fertigation. By actively monitoring VPD, you can time these applications more precisely, improving the efficiency of nutrient delivery and ensuring plants are neither over- nor under-watered. This approach promotes strong, resilient growth, helping your crops reach their full potential.
How is Leaf VPD Measured?
Our sensors provide real-time leaf VPD data, making it easy to see when your plants are in their ideal moisture zone. The system continuously monitors air temperature and humidity, calculating VPD and alerting you when conditions are right or if adjustments are needed. With this information, you can time your irrigation and fertigation applications precisely, ensuring your plants receive water and nutrients when they can best absorb them.
How Can the Data Help You Make Decisions?
Leaf VPD monitoring is a powerful tool for optimizing irrigation and fertigation schedules. When VPD is in the ideal range—typically between 0.3 and 1.2 kPa, depending on temperature—plants are more receptive to both water and nutrients. By maintaining VPD within this range, you ensure plants are taking in just the right amount of moisture, maximizing the effectiveness of irrigation and nutrient delivery through fertigation. This targeted approach reduces waste, boosts nutrient uptake, and supports healthier growth, leading to better yields and more efficient resource use.
