Better Germination, Better Uniformity, Less Disease Pressure
Since onions have a shallow root system, frequent irrigation is the best way to achieve high yields and uniform bulbs. This makes drip irrigation a no-brainer for onion growers.
Why choose precision irrigation for onions?
- Deliver the best quality to your market
Maintaining consistent soil moisture with drip irrigation restricts excessive root growth and reduces the risk of bulbs splitting. - Don't waste your fertilizers
Onion plants have a shallow, fibrous root system, so fertilizers applied in the beginning of the season end up getting pushed below the root zone by the rain, ultimately making the nutrients unavailable to the crop. Precision fertigation offers consistent nutrition that always reaches the roots and eliminates waste. - Less diseases, more yield
When irrigating with drip, water goes directly to the roots, leaving the leaves dry. Lack of leaf moisture significantly reduces foliar diseases such as Downey Mildew or Peronospora, minimizing crop loss and fostering up to 30% higher yields. - Efficient phosphorus application
Onions need soluble phosphorus to grow, but phosphorus has low mobility within the soil. Therefore, when using precision fertigation, you can apply consistent small doses as close to the active root hairs as possible, boosting phosphorus uptake by the plant.
Things we often get asked:
-
Can I irrigate my onion crop daily?
Yes. Onions have small root system, so irrigation frequency is key. The amount of time between irrigation applications can be adjusted to match both the growth stage and the soil type, empowering daily irrigation.
-
Can drip irrigation protect my crops?
Yes! Many onion canopy diseases thrive in high humidity environments. For example, Downey Mildew and Peronospora spread more rapidly in high humidity areas. Because drip irrigation maintains relatively low humidity, it reduces the spread of disease and the need for spraying crop protection chemicals.
-
Can my onions be monitored and irrigated remotely?
Advanced digital tools allow you to monitor and manage your irrigation and nutrition from the palm of your hand, giving you remote access by mobile, tablet or computer.
-
Why should I use drip irrigation over other irrigation methods?
Because the onion’s root system is relatively small, any resources distributed below the root zone or outside the plant radius is essentially wasted. Therefore, sprinkler systems are wasting nearly 30% of the water and nutrients you are distributing. On top of irrigating the root zone only, drip systems generate no evaporation or run-off, creating even higher levels of efficiency.
