The challenge

The challenge for corn farmers

Corn reacts dramatically to water, nutrients and radiation. But while radiation is usually a given, you can control your corn’s exposure to water and nutrients. While traditional irrigation systems like flood and pivot give you some control, they’re also inefficient and less uniform in the way they apply water. This becomes even more evident across different soil types, so they make it hard to ensure you get uniformly better crops. These traditional irrigation methods are also not relevant to uneven topography or odd shaped fields.

How precision irrigation helps

Precision irrigation gives you better control by delivering water and nutrients directly to the roots of each plant, in specific combinations, according to your plants’ developmental stages. It fits into any plot, and can be applied to all topographies, field sizes and soil types. So you can maintain optimal soil moisture and nutrient levels in all conditions.

And if you add digital controls to your system, you’ll be able to monitor and optimize your yield as it’s growing, gaining data about every aspect of your field and local climate. So wherever you are, whether you’re growing for grain, silage, seed production or sweetcorn, you’ll ensure consistently high, top-quality yields every season. And even bigger profits.

Corn FAQs

  • Should I use surface or subsurface drip irrigation?

    Subsurface drip irrigation (SDI) systems are most suitable for large-scale cornfield operations. Compared with on-surface systems, SDIs deliver additional benefits such as lower labor requirements, and operational simplicity. SDI systems favor modern tillage practices such as no-till or minimum tillage.

    On-surface systems are best for small to medium-scale growers, and for use on extremely sandy soil plots. They’re also a great option for plots that are deep-tilled or for plots that are rented where growers would prefer to avoid investments in non-mobile equipment. But bear in mind that while they require a lower initial investment, they do carry a higher operational cost.

  • If I have a lot of rainfall, will drip still be a good investment?

    Definitely. While having ample rainfall is obviously a huge advantage, rain is never timely enough to allow the crop to reach its full yield potential. This is even more evident with sandy soils that have a lower water holding capacity. On top of that, drip is also a nutrient delivery system that allows you to fertigate and control the nutrient levels in your soil in a precise and economical way. Applying all of your fertilizer in a single application can be wasteful, especially under rainy conditions that provoke leaching. Splitting your nutrient application along the season guarantees that your crop gets what it needs when it needs it. This is what makes drip systems the perfect  tool for increasing productivity in previously rain-fed plots.

  • What if I have an uneven topography or irregularly shaped cornfield?

    Drip irrigation fits all plot shapes and sizes, all soil types and all topographies.  You can use pressure compensating dripperlines that maintain the same flowrate across different pressure levels so every plant in the field gets exactly the same amount of water and nutrients no matter the elevation changes or distance from the water source.
