A stable oxygen supply to the roots is essential. Low-oxygen conditions can lead to inactive roots, resulting in several negative consequences:<\/p>\n\n\n\n<p>1. Reduced nutrient uptake \u2013 Due to decreased root activity, less nutrition is absorbed, which can hinder plant growth.<\/p>\n\n\n\n<p>2. Reduced water uptake \u2013 Roots lacking sufficient oxygen lose their ability to absorb water effectively, putting the plant under stress, especially during warm periods.<\/p>\n\n\n\n<p>3. Increased susceptibility to diseases \u2013 Inactive roots are more vulnerable to root diseases, such as infections caused by the fungus Pythium, which commonly occurs under low-oxygen conditions.<\/p>\n\n\n\n<p>To visualize the effect of oxygen on plant resilience, trials were conducted with tomato and cucumber. The tomato plants were grown with their roots directly in a nutrient solution, while the cucumbers were first sown in pots, which were then placed in the nutrient solution. Pythium was added to all nutrient solutions. In half of the setups, air was bubbled through the solution, while in the other half, no aeration was applied.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<p><strong>Tomato<\/strong><\/p>\n\n\n\n<p>The low-oxygen conditions led to root damage in the tomato plants. The plants in the oxygen-deprived environment died, while the plants that had access to oxygen were affected but survived.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img fetchpriority=\"high\" decoding=\"async\" width=\"351\" height=\"342\" src=\"https:\/\/sendot.nl\/wp-content\/uploads\/2024\/11\/zuurstofarm.jpg\" alt=\"\" class=\"wp-image-3596\" srcset=\"https:\/\/sendot.nl\/wp-content\/uploads\/2024\/11\/zuurstofarm.jpg 351w, https:\/\/sendot.nl\/wp-content\/uploads\/2024\/11\/zuurstofarm-300x292.jpg 300w, https:\/\/sendot.nl\/wp-content\/uploads\/2024\/11\/zuurstofarm-12x12.jpg 12w\" sizes=\"(max-width: 351px) 100vw, 351px\" \/><\/figure>\n\n\n\n<p><\/p>\n\n\n\n<p><strong>Cucumber<\/strong><\/p>\n\n\n\n<p>A similar pattern was observed in cucumber as in tomato: without oxygen, the plants died due to Pythium infection; when oxygen was available, some (limited) damage was still visible, but the plants survived.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"760\" height=\"421\" src=\"https:\/\/sendot.nl\/wp-content\/uploads\/2024\/11\/zuurstof-komkommer.jpg\" alt=\"\" class=\"wp-image-3597\" srcset=\"https:\/\/sendot.nl\/wp-content\/uploads\/2024\/11\/zuurstof-komkommer.jpg 760w, https:\/\/sendot.nl\/wp-content\/uploads\/2024\/11\/zuurstof-komkommer-300x166.jpg 300w, https:\/\/sendot.nl\/wp-content\/uploads\/2024\/11\/zuurstof-komkommer-18x10.jpg 18w\" sizes=\"(max-width: 760px) 100vw, 760px\" \/><\/figure>","protected":false},"excerpt":{"rendered":"<p>In de teelt van glasgroenten speelt de zuurstofconcentratie in het substraat een essenti\u00eble rol in het waarborgen van een gezonde plantgroei en optimale opbrengst.
