For example, a base system utilizing the wirelessly transmitted information of several sensors appropriately distributed over various sectors of a round field irrigated by a center-pivot irrigation system could tell the irrigation lever exactly when and what field sector needs to be irrigated.

A Phase I research grant from the
National Science Foundation in 2007 showed that the leaf sensor technology has the potential to save between 30% and 50% of irrigation water by reducing irrigation from once every 24 hours to about every 2 to 2.5 days by sensing impending water deficit stress. Leaf

Precision irrigation monitoring using the SG-1000 leaf sensor and commercial data loggers for irrigation control has been achieved in recent years. Researchers have found a direct correlation between leaf thickness and

The agriculture sustainability benefits of water and energy savings have been established using the SG-1000 leaf sensor under field conditions and in greenhouses. Plant science researchers and agronomists have utilized the SG-1000 Leaf Sensor for studying the relationship between water content and

In a 2008 USDA sponsored field study AgriHouse's SG-1000 Leaf Sensor attached to dry beans demonstrated a 25% savings of irrigation water and pumping cost. In 2010 the
