VitaLite: from drain to gain!

It is often said… “In the future it will all be about kilograms of product per m3 of water instead of kilograms of product per m2 of cultivation area.”

Do you recognize this? Greenhouse Grower I am not able to grow anymore, I can’t expand my greenhouse There is not enough water to irrigate because of water shortage I can’t compete anymore in the market Production costs (per kg product) are high, partly due to high fertilizer cost What keeps the Greenhouse Grower awake? How do I reduce or eliminate the risk of infection? Yield losses occur because plant pathogens in irrigation water (from drain) infect the crop How can I change the bad ‘polluting’ growers image? Drain water, containing fertilizers and other substances, is discharged to the surface water

Common challenges for growers Water shortage High fertilizer cost What keeps the Greenhouse Grower awake? Contaminated irrigation water Pollution & bad image

United Farms in Mexico 65 ha high-tech greenhouses in Queretaro, Mexico CEO: Mauricio Revah Mission: Internationally competitive and sustainable greenhouse operating company 7/8/2019

Fertilizer cost at Finka, United Farms Average over 15 weeks Uptake & transpiration (nutrients & water) Irrigation = 76 m3/ha/day = $1053/ha/day* Drain (46%) = 35 m3/ha/day = $875/ha/day* water + nutrients if discharged = waste / pollution water + nutrients pathogens: bacteria fungi viruses if recirculated = plant disease 7/8/2019 * $15.3 (Mexican peso) = 1 US dollar

The VitaLite UV disinfection unit … allows you to recirculate your drain water and therefore save on water & fertilizer … … without introducing plant diseases and chemical residues to your crop. 7/8/2019

Return on Investment Fertilizer savings at 29% recirculation: Up to 15,500 USD /ha/year Fertilizer savings at 29% recirculation: 250 Mex peso/ha/day = 16,3 USD/ha/day= 4500 USD/ha/year at 100% recirculation = 15,500 USD/ha/year down to 1 year VitaLite payback period can be as low as 1 year based on fertilizer savings alone depends on disinfection capacity requirement & efficient use cost yield sales VitaLite ROI is further increased by: reduced water cost increased crop yield (due to improved water supply & crop health) increased sales (due to better company image) 7/8/2019

Satisfaction and cooperation United Farms installed multiple VitaLites for disinfection of drain water. “A disinfection system has a rapid return on investment up to 40% of the irrigation water can be reused, saving on the cost of water and fertilizer.” United Farms and Ridder have signed into a long-term cooperation. 7/8/2019
