Crop Water Stress Index CWSI
The crop water stress index (CWSI) was developed (in 1981) as a normalized index to quantify stress and overcome the effects of other environmental parameters affecting the relationship between stress and plant temperature. Workswell’s WIRIS Agro is the first device of its kind designed to map water stress across large areas in the field of precision agriculture. The aim of this method and device is to determine the value of water stress in the plant stand. For example, this information may be used to determine yield maps, optimize irrigation, or control water management remedies. Camera offers LWIR band sensor and 10x optical zoom RGB camera with resolution full HD (1920 x 1080 px) for biomass cover index evaluation.
