Why is watering so important?
Crop quality is closely tied to plant irrigation. Both the amount and the timing of watering are important, and should be carefully planned and monitored. Next to light, watering is the next most critical production factor.
What are the effects of under watering?
Even mild under‐watering causes photosynthesis to shut down. When plants lack adequate water for uptake, all aspects of plant development become stunted: leaves, fruit, flowers, stem growth are all affected. Depending on the stage of plant and degree of water stress, this stunting can have a permanent effect on the plant. Severe under‐watering results in a burned appearance on the foliage and flowers.
What are the effects of overwatering?
Excessive watering can be as or more damaging to the crop as under‐watering. The soil environment which is conducive to plant growth contains both readily available water and air. When soil is over‐watered, the air is ‘driven out’ of the soil, and the roots are unable to survive very long in this condition. If persistent, the roots die, and the plants are unable to uptake the water and nutrients they need. A wet root environment also promotes many root diseases.
