Horticulture growers are faced with root diseases. Pathogenic organisms cause production loss in substrate cultivation. Several strategies are used to counteract these problems, aimed at eliminating the entire microbiology. The Triton bioreactor not only combats the pathogens but also ensures a balanced microflora in the system.
Healthy microflora
A healthy microbiological population is established in the reactor vessel by the regulation and interplay of air, water and a composite nutrient medium. This population becomes resident, meaning that microbiology thrives and belongs there.
The resident microflora, consisting mainly of bacteria, fungi and yeasts, ensures that the organic pollution is 'eaten'. Because of this the non-resident microorganisms in the watering system have less nourishment. This way Agrobacterium rhizogenes for example, the bacterium that causes crazy roots, gets no chance to grow. An inherent defense system against pathogens is created.
Oxygenated watering system
The result is healthy root development, so that the crop is less susceptible to pathogens. This provides a major contribution to optimal production. In addition, the water in the reactor is saturated with oxygen. This is done by aerating the water from above and from below. This adds a lot of oxygen to the watering system.
Also, less oxygen is consumed by the microbiology in the watering system by removing biodegradable organic material from the water. This results in more oxygen at the drippers, guaranteeing an oxygen-rich root environment. This allows for better plant growth and a more resilient crop.
Practical experience
The Triton microbiological reactor is the result of a collaboration between the Dutch water technologists at Aqua-Terra Nova and filtration specialists from Moor Filtertechniek. In the past year, the system was extensively tested in eggplant and tomato growing companies. Practical experiences are much better water quality, a naturally growing root system and a more resilient crop due to balanced microflora in the watering system. The bioreactor had the best results where multiple control strategies were applied, like the use of oxidizing biocides. Besides the application in substrate cultivation, the system is suitable for cultivation where there are water quality issues.
