WORLDS BEST INNOVATION
IN PHYSIOLOGICAL CALCIUM DEFICIENCY
ON LEAFY VEGETABLE CROPS!
The worlds best method against tipburn in lettuce:
to grow plants in negative DIF conditions!
In Negative DIF conditions – tipburn is decreasing and the need to use chemicals to prevent diseases and pests is reduced or totally absent.
This method is replicable around the globe and can be used in organic agriculture and in vertical farming.
It helps to conserve the energy, because temperature is higher at night time, which period is shorter.

Discoveries by Dr. Margit Olle:
1. (first innovative idea): Plants were grown under a far-red filter, which filters out much of far-red light. Far-red light is responsible for the elongation of plants. When grown under a far-red filter to remove much of the far-red light then plants remain more compact (knowledge from Japan). With far-red filter plants contain more Calcium and show fewer Ca deficiency symptoms (Margit Olle discovery, not a patent, unfortunately).
2. (second innovative idea): Negative DIF is when the night temperature is higher than the day temperature. In such condition’s plants stay more compact (Roar Moe from Norway have lots of papers about it). Under negative DIF conditions plants contain more Calcium and there are fewer Ca deficiency symptoms on plants (Margit Olle discovery, not a patent, unfortunately).
