1 Development l off an Inventory Management g Tool for Nurseries Usingg an Unmanned Aerial Platform Evaluating l i a More Sustainable i bl Controlled ll d Release Fertilizer for Ornamental Crops using J. Owen*, J. Robbins, R. Ehsani, D. Saraswat, a Struvite Byproduct from Waste Water Treatment J. Maja, H. Stoven, S. Doane, C. Landgren

2 INVENTORY MANAGMENT Commonality between growers Estimates based on small percent of population Inaccurate Increasing technological advancements ecreasing te technology chnology costs Decreasing Increasing labor cost and decreasing availability Enhanced inventory projections Quantitative analysis at time of harvest 1992 images of American Nurserymen provided by Jim

4 WHY AERIAL? Eliminate issues with terrain Cover large area at one time Decreased technology costs Decreased nursery and cost Evaluating l time i a More Sustainable i bl Controlled ll d Increased accuracy Release Fertilizer for Ornamental Crops using a Struvite Byproduct from Waste Water Data readily available Treatment Future applications Crop scouting Bare soil imagery Irrigation and drainage planning Academic and Extension Education

5 AERIAL IMAGERY (2002) SATELITE IMAGERY (2010) Evaluating l i a More Sustainable i bl Controlled ll d Release Fertilizer for Ornamental Crops using a Struvite Byproduct from Waste Water Treatment

6 REMOTE AERIAL PLATFORM ADVANTAGES: Lower cost (< $10,000) Ease of use; on demand capability ((can be flown byy anyy trained grower/farmer) Higher resolution (1 inch) ower altitude ((< 400 fee feet) t) Lower Vertical take off and landing Greater payload capacity than most unmanned aerial vehicles (2 5lbs) Multi rotor platform is more stable and compared to single rotor helicopter

7 REMOTE AERIAL PLATFORM MiKroKopter US, Watsonville CA Altitude control GPS position Waypoints navigation Payload: kg Radio control transmitter ~ GHz 1 2 km range Total Weight (without battery) 1260 g Maximum altitude 350 m Maximum speed 8 m/s

8 IMAGE COLLECTION Roll and pitch compensated Shutter and controls can be operated using the R/C transmitter. Sony NEX 5 camera APS HD CMOS sensor 14.2 megapixels Weight: g 10.1 oz ((287g) g) Sony SEL 16mm f/2.8 wide angle lens
