Irrigation tip of the month for April "Maintaining the right vegetative–generative balance while protecting root health" April is one of the most demanding months for greenhouse tomato growers in Central Europe, where rapid crop development coincides with unpredictable spring weather. Drainage levels around 30–35% help maintain balance without over-irrigating.
From the last irrigation of the day to the first the next morning, slab moisture should decrease by around 8–10%, with a small buffer after sunrise before irrigation resumes. Slab moisture is gradually increased to around 70–75%, and irrigation frequency becomes more closely aligned with incoming radiation.
Why this matters: This matters when it gives operators a clearer way to manage water, nutrients, and root-zone risk. That kind of control usually improves both resource efficiency and crop consistency.
Frequently Asked Questions
What should growers evaluate before changing a lighting strategy?
They should look at crop type, canopy structure, current light distribution, energy cost, expected yield gain, and whether the new strategy improves whole-canopy efficiency.
Why is light distribution often as important as light quantity?
Because adding more photons to already saturated leaves does less work than improving how light reaches the parts of the canopy that are still underperforming.
