Corn subsurface irrigation

Corn, to produce at its full potential, needs good water availability during the growth critical stages of the crop, especially during flowering, when water stress can cause an irretrievable production loss.

Moreover, since corn performs its cycle during the least rainy period of the year, to be really productive, corn cultivation must be supported by irrigation.

Basing on corn irrigation experience over the last few years, subsurface irrigation, together with fertigation, has shown to be (as it already was for many other crops) the most efficient system with the best cost-benefit ratio.

The precision and uniformity of the system allow homogenous plant growth, even along the plot edges.

Also, the plants and the areas that are not reached by the roots are not irrigated directly, thus minimizing the risk of fungal diseases, soil compaction and asphyxiation.

Advantages of subsurface irrigation

Corn subsurface irrigation makes the management of irrigation easier than traditional overhead irrigation or flood irrigation systems, having practical as well as economic advantages:

• Possibility to irrigate even in windy conditions;
• It allows the irrigation of larger surfaces (than overhead irrigation);
• Increase in yields per hectare;
• Increased supply uniformity and efficiency;
• Prevents losses by evaporation;
• Increased fertigation efficiency due to the distribution of fertilizers in the root zone;
• Improved weed control;
• Better performances by reduced consumption of water and fertilizers;
• Reduced plant water stress;
• The system can be used for other crops by rotation: soybean, wheat, alfalfa;
• Reduced energy consumption;
• Reduced total cost, thanks to reduced water, fertilizer and energy consumption;
• Longer system durability with the advantage of no vandalism or damages caused by insects;
• The system is completely automated, which results in cost reduction.

Fertigation System for Corn

To obtain a higher production per hectare, fertigation can be used in corn cultivation. This technique, among other things, is capable of improving the quality of the product.

Thanks to the administration of fertilizers through the dripline, it is in fact possible to manage any corn deficiencies, which can compromise a good harvest. Fertilizers are delivered more precisely directly to the roots, thus reducing waste.
