An IT expert promotes ‘smartphone farming’
Quang Nam, February 21 (VNA) - An IT engineer in central Vietnam is demonstrating the value of hydroculture as an effective way to build climate change resilience in the storm-prone region. After working with the military-run telecom group Viettel for seven years, Nguyen Quoc Phong decided he wanted to do something else. The 33-year-old man from Nui Thanh district in central Quang Nam province has since used his IT know-how and experience to study and promote hydroponic farming, launching a startup of his own. Phong surfed the internet for information and solutions, found suppliers in the Netherlands and Israel, imported materials and quality fertiliers and seeds. “It’s not new in the world, but it has just emerged in central region. Farmers have a long tradition of growing vegetables in the soil, which is low cost and easy, but also carries the risk of contamination with water and air pollution already at alarming levels. And with rapid urbanisation in the region, it is not going to get better soon. “Local farmers still hesitate to change to new agriculture, or hi-tech farming. They are used to growing with easy tools, but not electronically controlled devices or smart-phone guided production,” Phong said, explaining why his company, H2O Farm Viet Nam, has launched a package solution. Phong said the package, including recycled water mixed with fertiliser, a pumping system and pipes made with durable material, would help farmers save a lot of time working with soil, manual watering and dealing with pest problems. “Farmers can manage operation of the system with their smartphones to set up nutrition pumping timer for the vegetables, and they do not need to work directly with hazardous pesticides. “However, they have to change from their labour-intensive farming into hi-tech application production with stricter conditions like using toxin-free water and specific doses of other inputs like fertiliser and sunlight,” he said. Phong explained that water at all the farms have to be tested to eliminate hazardous contaminants, while seeds and fertilisers from the Netherlands and Israel would offer suitable material for hydroponic farms. He said 24-hour programmed pumping system will help carry a mixture of water and nutrition to grow saplings. “It’s like a stream running day and night. Roots will absorb nutrition from the water running through pipes. Each sapling grows in a plastic box, and farmers can harvest easily by moving it up after 25 days,” he said, adding that a small household’s hydroponic garden could produce 40kg of greens each month. Household gardening Tran Thi Anh Thu, a Da Nang resident, said she installed a 6sq.m hydroponic garden on her rooftop eight months ago, growing vegetables for her family. “I could harvest vegetables from this garden 25 days after sowing. I do not have to buy these vegetables from the market anymore, because the garden provides plenty and we even have some for neighbours,” Thu said. Her family needs at least 3kg of fresh vegetables a day. “I invested 10 million VND (442 USD) for installation of the hydroponic system including water pipes, beds, pumps and seeds. I just spend a little money (around 5 USD) for buying new seeds or fertilisers a month.” Thu said she did not spend a lot of time on the garden, and had more time now for housework and caring for children. The 42-year housewife also said she had planted vegetables in soil on plastic trays or styrofoam boxes, but that required more time to water, protecting the plants from pests and rats. She said the hi-tech garden was really suitable for household that wants safe vegetables. Bui Thi Thanh Suong of Dien Ban district in Quang Nam province, said her family had grown vegetables for 20 years via traditional farming, and only recently began hydroponic farming as a trial. “In cooperation with the H2 Farm Vietnam company, we have developed a small hydroponics area on our 3,000sq.m garden with total investment of 70 million VND (3,000 USD),” Suong said. “We saw that growers did not waste time to clear weeds, prepare soil or halt crops because of rain or floods.” The 26-year-old woman said that in hydroponics, pest and insect attacks could be avoided, and strictly tested quality seeds would ensure a bumper crop. "While it requires more investment than traditional farming, the focus is on consumers seeking high-quality produce," she said. “High and medium income customers have gradually been seeking safe food and vegetables. They are willing to pay higher prices for daily greens at selected places,” she said. She said hydroponic salad greens, including lettuce costs between 60,000 VND (2.6 USD) and 90,000 VND (3.9 USD) per kilo, much higher than normally grown vegetables, which only cost between 10,000 VND (0.44 USD) and 40,000 VND (1.7 USD) per kilo. Suong said her family supplies 70kg of vegetables every day to farms with the Vietnam Agriculture Practice (VietGAP) certification. However, hydroponics is still limited to growing leafy vegetables, and it should be expanded to other products like beans, pumpkins, potatoes and tomatoes, Suong said. Minimum cost Phong said his company can design a household hydroponic garden of just 2 to 6sq.m at minimum costs of 6 million VND (265 USD) to 8 million VND (354 USD). He reiterated that hydroponics can help prevent the alarming overuse of stimulants in agriculture. He said he plans to expand hydroponics into mountainous areas in Quang Nam, where farms are destroyed by disasters every year, and promote household gardening in Da Nang and Tam Ky cities. “Household hi-tech gardening can supply safe greens to supermarkets or directly to urban communities, and its expansion would also reduce investment.”/.
