The success of soilless culture technology lies in providing the three elements that plants need to survive: oxygen, water and nutrients.
“Hydroponics has been touted as the great alternative for food production in the future,” says Vicenta Riera, Crop Marketing Specialist and Agronomist at Projar, “and this is backed up by statements from the FAO, which have indicated that food demand is expected to increase by 60% since there will be more than 9,000 million people living on the planet by 2050.” It is also necessary to overcome the limiting aspects of cultivation related to the environment, climate control, pests and diseases.
All this has led to an expansion of greenhouses to an overall area estimated at 485,000 hectares in 2021. However, a distinction must be made between greenhouse crops in soil (375,000-385,000 hectares), crops in hydroponic systems or without substrates (20 000-25,000 hectares), and greenhouse crops without soil in substrates (70,000-75,000 hectares).
“This significant increase was achieved thanks to the high efficiency of the system. At Projar, we have launched new projects in more than ten countries over the past five years,” says Riera.
The choice of soilless cultivation has multiple advantages for vegetable cultivation, in particular:
- Control of the culture medium to obtain the best vegetative and reproductive results of the plant.
- Early start of production (30%-50%).
- Increased production and number of plants per square meter.
- Use of culture bags or pots to optimize the use of space, allowing the arrangement of plants to be adapted to their development.
- Prevents deformation of the fruit as it avoids contact with the ground.
- Use of substrates that ensure greater aeration and good root drainage.
- Use of drip irrigation (little water, high frequency).
- Water reuse.
- Potential to be implemented anywhere.
- Better planning at all stages of cultivation.
- Reduced expenditure on fertilizers and pesticides.
“The benefits of soilless cultivation have convinced growers who previously cultivated in soil to change their preferences. Today, hydroponic/soilless technologies, in combination with greenhouse technologies (farming in a controlled environment during certain periods) are very precise and undoubtedly lead to yield increases. says Riera (in the photo).
Additionally, having the right technical know-how on soilless crop management will help growers achieve good plant health and productivity. “We offer a consulting service and technical advice to our customers thanks to a team of technicians specialized in intensive hydroponic production in the ground and in greenhouses. In this way, we reinforce our commitment to contributing to productive success,” she says.
