What is the main benefit of aeroponics?
A. Higher water usage
B. Maximum oxygen exposure to roots
C. No need for nutrients
D. Slower growth rate
Answer (2)
The main benefit of aeroponics is maximum oxygen exposure to roots, which supports healthier growth and nutrient absorption. This method allows for efficient water use and reduced risk of diseases. Therefore, the correct answer is B.
;
The main benefit of aeroponics among the given options is (B) Maximum oxygen exposure to roots .
Aeroponics is a method of growing plants without soil, where the roots are suspended in the air and periodically misted with a nutrient-rich solution. Here's why maximum oxygen exposure to roots is considered a major benefit:
Increased Oxygenation :
In aeroponics, the roots are not submerged in water, allowing them to have direct exposure to air. This improves oxygen availability, which is critical for root respiration and overall plant health.
Enhanced Nutrient Absorption :
The increased oxygen levels can enhance the plant's ability to absorb nutrients more efficiently, promoting faster and healthier growth.
Faster Growth Rates :
With optimal nutrient and oxygen levels, plants can often grow faster than in traditional soil or hydroponic systems, leading to potentially higher yields.
Precision Control :
Aeroponics allows for precise control over the environment, including humidity and nutrient delivery, ensuring that plants receive exactly what they need without overwatering or nutrient waste.
Overall, aeroponics is a beneficial cultivation method because it optimizes the delivery of oxygen to plant roots, leading to healthier and potentially faster-growing plants compared to some traditional methods.
