1、Common Fertilizers Used in Corn Production

In corn production, leaching and denitrification losses are highest when soil water content is high. A commercially available nitrification inhibitor, Nitrapyrin, can be purchased as N-Serve® or InstinctTM, whereas Docyandiamide (DCD) can be purchased in SuperU®.

2、Diagnose fertilizer burn in corn

“There are at least three situations where we run into cases of fertilizer injury this time of year,” says Dan Quinn, Purdue Extension corn specialist. “Know how much actual product you are applying, and take steps to place it properly to help stay out of these situations.”

3、How to Apply Liquid Fertilizer to Corn

Applying liquid fertilizer to corn is a simple process that can be done with a few tools. The first step is to determine the rate of application. This will vary depending on the type of fertilizer and the soil conditions. Once the rate is determined, it is time to prepare the field.

4、Misunderstanding of foliar fertilizer spraying

Foliar fertilizer spraying is best carried out in the growth transition period of crops, with an interval of at least 20 days. Generally speaking, it is sprayed 2-3 times per season. The suitable period of foliar fertilizer spraying of different plants and fertilizers is also different.

How to Identify and Treat Fertilizer Burn on Plants: A Complete 2026

Effective management of fertilizer practices, guided by both qualitative symptoms and quantitative soil testing, can prevent the harmful effects of fertilizer burn, ensuring plant health and garden vitality. Early detection of fertilizer burn is crucial to mitigate damage and begin remediation.

The Dos and Don’ts of Foliar feeding

Used in both vegetative and flowering stages by many growers, foliar feeding involves spraying water-dissolved formulas directly onto plant leaves. This method allows for nutrients to pass directly into the plant’s vascular system for visible results within 48 hours.

Urea Disolved in Water and Sprayed

We placed the fertilizer in the basket and used a hose or the hand gun to dissolve it into the tank already half full and agitating. Anything that won't dissolve through the screen doesn't go in the tank.

Watering Corn

It's better to give your corn crop one long soak per week if no rain falls, rather than several short watering sessions. The plants derive most of their water and nutrients through the root system. If too little water is applied per session, it won't reach the roots and your efforts will be wasted. Remember to take into account any rain that falls.

Spraying water-soluble fertilizer on corn is a common agricultural issue. Improper handling may lead to stunted plant growth or even death. Below are detailed steps to address this problem:

1. Immediately Stop Irrigation: Once water-soluble fertilizer comes into contact with corn, halt irrigation immediately to prevent excess fertilizer from seeping into the soil and crops.

2. Remove Contaminated Areas: Use sprayers or tools to clean contaminated soil and plant tissue from the cornfield. Ensure no potentially affected areas are overlooked.

3. Flush the Soil: Irrigate the affected area with a significant amount of clean water to dilute and remove residual fertilizer. The flushing process typically requires several hours to ensure all traces are washed away.

4. Reapply Fertilizer: After cleaning, consider reapplying fertilizer. Select a product suitable for corn and follow recommended dosages and methods.

5. Monitor Crop Growth: Closely observe corn growth post-fertilization to confirm recovery. If abnormalities arise, further intervention or adjustments to fertilization strategies may be needed.

6. Preventive Measures: To avoid recurrence:

   • Use safe, effective fertilizers compliant with local agricultural regulations.
   • Follow product label instructions carefully before application.
   • Regularly inspect soil and crops to detect and resolve issues early.

7. Education and Training: Farmers should prioritize learning proper fertilizer use. Participating in training courses, workshops, or consulting experts can enhance knowledge and agricultural management skills.

8. Establish an Emergency Plan: Develop a protocol for potential fertilizer-spraying incidents, including operation steps, timelines, and contact information. This ensures rapid response and minimized losses.

9. Communicate with Suppliers: If fertilizer quality is compromised, contact suppliers for solutions or replacements. Report issues to local agricultural authorities for investigation and action.

10. Legal Recourse: In cases of severe damage, pursue legal pathways by gathering evidence, seeking legal counsel, and engaging in legal proceedings.

spraying water-soluble fertilizer on corn requires careful attention. Following these steps effectively mitigates risks, ensuring crops regain healthy growth.
