Optimizing Irrigation with Soil Moisture Deficit

What's Soil Moisture Deficit?
Soil Moisture Deficit (SMD) is all about knowing how much water your soil needs to keep your crops growing strong. Think of it like this: SMD measures the gap between how much moisture is in the soil right now and the perfect amount your crops need. We give you this number in millimeters (MM), which is easy to understand—1 millimeter equals 1 liter of water per square meter, just like measuring rainfall. By keeping an eye on SMD, you’ll know exactly when and how much to water, avoiding both under-watering and over-watering that can hurt your plants and your harvest.

To delve deeper into our technology, we have an insightful article written by a plant scientist that explains our SMD technology in-depth. This piece is based on a recent trial and showcases the research conducted to perfect our approach. You can find this valuable resource at this link for more information.
How is Soil Moisture Deficit measured?
It’s simple—our soil moisture sensors give you real-time data straight from your fields. We track two key things: the Field Capacity Line, which shows how much water your soil can hold, and the Stress Line, set at 25% below that to flag when things are getting too dry. The best part? Our system self-calibrates to your soil, and you can adjust the Stress Line depending on your crop or soil type. These lines make it easy for growers to keep moisture in the perfect range, ensuring smart, precise irrigation every time.
How Can the Data Help You Make Decisions?
With Soil Moisture Deficit (SMD) monitoring, you can fine-tune your irrigation using Regulated Deficit Irrigation (RDI). The data shows exactly when your soil is dipping below its ideal moisture level, letting you time your watering perfectly. This way, you're only watering when your crops actually need it—no more over-watering or under-watering. It’s a simple, data-driven method that helps boost water efficiency, keeps your plants healthier, and ultimately leads to better yields and more sustainable water use.
