**Variable Rate and its benefits**

Variable Rate Application (VRA) is a technique used in precision farming that focuses on the automated application of agricultural inputs in variable quantities based on measured crop or soil heterogeneity.

“The right amount, at the right time, at the right place.”

**Nitrogen**

- Up to 5% yield increase
- Up to 15% savings
- Up to 20% increases combine throughput
- Less lodging

**Growth Regulators & Fungicides**

- Up to 3% yield increase
- Up to 15% savings
- Less lodging
