Less disease and better quality under diffuse coating
Agrokultura Group is finding it easier to find the balance between optimal use of sunlight and crop protection. In the video, Sergei Volkov explains how ReduSystems coatings play an important role in this.
The company grows tomatoes, cucumbers, peppers, aubergines and strawberries on 58 hectares in Kashira, 120 kilometres from Moscow. In the summer, temperatures rise in the land climate. "If we don't take any measures, the plants become overheated. This makes them thinner and more susceptible to disease and pests," says Sergei Volkov. In past, we therefore used to close the movable screen for much of the day during the summer.
The arrival of ReduSystems coatings really helped. First, they gained experience using ReduSol and ReduHeat, and then continued with diffuse coatings. They found that ReduFuse IR was best for protecting tomatoes and cucumbers, while ReduSol was good for the young plants. "This strategy gave good results last year. So we'll use the same method next season," he says.
Converting light into production
The young plants are very vulnerable. A thick layer of ReduSol (20 buckets per hectare) provides protection against light and heat so that the crops can develop properly. Tomato and cucumber plants can take much more light. They are protected by 16 buckets of ReduFuse IR per hectare. This coating diffuses the light in the crop and keeps out heat radiation so that the plants do not overheat.
"Under ReduFuse IR, you don't get any bright light spots, which would cause stress in the crop. The light falls deeper into the crop and is distributed both horizontally and vertically. That improves the climate in the greenhouse. You can really see it: the plants look better. Productivity is higher, the product quality is better and there's less disease and fewer pests," says Sergei Volkov.
Occasionally, it is still necessary to use the movable screen, but in general the crop can usefully convert a great deal of light into production. And not unimportantly: the coatings have enormously improved the climate for the people working in the greenhouse.

Controlling growth with light: more in winter, diffuse in summer
For a grower, every ray of sunlight entering the greenhouse in winter is a bonus. Light is also welcome in summer, provided it is properly distributed throughout the crop. This can be achieved by combining coatings. Two vegetable growers are leaders in this field in the Netherlands.
Growing under a new coating is a learning process
Leo and Maikel van den Berg have been growing sweet peppers at two locations in Bleiswijk, the Netherlands, since 2012. This was the year they took over a greenhouse from a colleague. During the first season they found it difficult to maintain sufficient growth at this new location. To try and achieve...
ReduFuse makes it possible to produce summer strawberries in the greenhouse
Kwekerij Loos, is a front-runner when it comes to the sustainable year-round production of strawberries. The nursery has three hectares of greenhouses that are heated with waste heat. Last year, for the first time, it achieved a summer crop under glass. This was made possible by having the diffuse coating,...
