ecagon Devices designs, manufactures, and distributes scientific instrumentation with applications in precision agriculture, irrigation scheduling, and winery management. Decagon was originally founded in 1983 by renowned soil scientist Dr. Gaylon Campbell and has continued to foster growth through the collaboration of world class soil scientists and innovative engineers. We have spent the last twenty years helping farmers, researchers, and government agencies understand how much water is in the soil in order to allow water to be added only when necessary. In the past, irrigation used for landscaping has not been widely restricted. However, as the scarcity of water increases, homeowners and turf managers are encountering water restrictions they feel may threaten the landscape quality. Fortunately, the pains due to water limitations have led to innovations in the irrigation industry. Realistic alternatives are becoming available to agricultural and horticultural professionals interested in conserving water while meeting the needs of the landscape. The more innovative professionals rely upon direct measurements of the amount of water in the soil to determine irrigation schedules. These professionals are asking for Decagon soil moisture sensors by name.

X Irrigation control based on soil moisture works similar to a home thermostat. Recently, a prominent horticulture professor bought Decagon sensors for use as irrigation triggers. His timer method was wasting too much water. As shown above, beautiful petunias were grown with a volumetric water content set-point of 30 percent with no wasted water.

SMART OEM SENSORS PROMOTE IRRIGATION CONSERVATION AND EFFICIENCY THE DECAGON PROMISE DURABLE Our soil moisture sensors were designed to be installed in the soil and left in rugged conditions for 5+ years. The fiberglass support with a copper core will not degrade over time like other lower cost soil moisture sensors. EASY TO INSTALL Our soil moisture sensors are small and pointed. They were designed to be installed easily every time with no large trenches, leaving unsightly mounds and holes in the landscape.

EASY TO USE Why choose monitoring equipment with data that require difficult calculations? Our sensor output is correlated with soil volumetric water content. Decagon sensors were designed to give you the information you need to both conserve water and maintain a beautiful landscape.
