Chlorosis
A condition in plants where leaves turn yellow due to a lack of chlorophyll, impairing their ability to photosynthesize effectively.
Также говорят: leaf yellowing, chlorophyll deficiency
Chlorosis is often a symptom of nutrient deficiency, poor drainage, or extreme soil pH levels. When plants cannot produce sufficient chlorophyll, their growth slows down, and they become highly susceptible to environmental stress and pests.
Common mistakes include excessive watering, which causes root rot and nutrient lockout, and over-applying fertilizer without confirming a deficiency through soil testing. Identifying whether the yellowing starts on new or old leaves is crucial for determining the missing nutrient.
Practical management involves the application of chelated micronutrient sprays for rapid absorption. Growers should monitor soil acidity and implement appropriate liming or acidification strategies to ensure long-term nutrient availability.
