Nitrogen, phosphorus, potassium, iron, and sulfur are nutrients that can potentially improve corn yield when applied as a foliar treatment. The objective of this trial was to evaluate the effect of FertiRain, Iron, PrimAgro P and various combinations on corn yield when applied as a foliar treatment.

To meet the large crop demand for nutrients like P and K, the suggested method is soil testing and soil application when a need is indicated. Both early and late season foliar fertilization have been researched extensively in Iowa.

Boosting Corn Yield: Foliar Fertilization Benefits

To ensure optimal growth and yield of corn, it is important to plan the application of zinc fertilizers correctly. The level of zinc in the soil and the method of application should be considered.

Recommendations for foliar feeding of corn

Corn is a rather demanding crop for nutrition. It gives a large yield only where the soil is rich in nitrogen and other elements. Foliar nutrition of corn is important throughout the growing season.

‌Core formula of corn foliar fertilizer spraying

‌The core formula of corn foliar fertilizer spraying is a combination of potassium dihydrogen phosphate, zinc-boron micro-fertilizer and brassinolide. Adjusting the ratio in combination with different growth stages can significantly improve yield and stress resistance.

Corn Fertilizer: How and When to Use It

When your corn looks a little peaky, a foliar feed can green it up quick-smart. Mix your liquid fertilizer with water, and with a sprayer, mist those leaves like you’re setting the mood with a room fragrance.

Corn Fertilizer Source and Application Method

Fertility application timing and method are very important for the maximation of corn yield potential. Many application types occur across the southern agricultural system including knifed-in soil applications, surface applications of liquid fertilizer, and surface-applied granular applications.

Foliar fertilizer for corn is a highly efficient and convenient fertilization method. It directly applies nutrients to the leaves of corn plants, which absorb and transport them, thereby enhancing both yield and quality. Below is a detailed guide on the proper usage methods and dosage of corn foliar fertilizer.

I. Correct Usage Methods of Corn Foliar Fertilizer

1. Preparation Phase

• Select Appropriate Foliar Fertilizer: Choose fertilizers based on the growth stage of corn and soil conditions. Common options include nitrogen, phosphorus, and potassium fertilizers, each serving distinct purposes and suitability.
• Clean Leaves: Before application, rinse corn leaves with clean water or a specialized cleaner to remove dust and debris, ensuring optimal absorption.
• Dilute the Fertilizer: Follow product instructions or professional advice to dilute the fertilizer to the correct concentration. A typical dilution ratio is around 1:1000.

2. Application Phase

• Uniform Spraying: Use a sprayer or soft brush to evenly apply the diluted fertilizer to both sides of the corn leaves, ensuring full coverage.
• Control Application Volume: Adjust the amount based on plant size and leaf area. Generally, 50–100 kg per mu (approx. 0.067 hectares) is recommended, though actual needs may vary.
• Spraying Interval: Depending on the type of fertilizer and crop condition, repeat applications every 3–7 days after initial use, adjusting as needed.

3. Post-Application Management

• Monitor Plant Response: Observe corn growth and leaf changes closely. Supplement with additional fertilizer if necessary.
• Adjust Fertility Strategies: Modify fertilization plans based on crop performance and effectiveness to ensure balanced nutrient supply.

II. Dosage of Corn Foliar Fertilizer

1. Recommended Dosage

• Tailor to Crop Needs: Different corn varieties require varying nutrients. For mid-to-late growth stages, 50–100 kg per mu is a reasonable baseline.
• Follow Industry Standards: Refer to national or local guidelines for scientific and effective application.

2. Precautions

• Avoid Overuse: Excessive application can lead to nutrient imbalance, plant diseases, or stunted growth.
• Combine with Other Fertilizers: Foliar fertilizers should complement, not replace, organic or chemical fertilizers to ensure comprehensive nutrient intake.

proper use of corn foliar fertilizer significantly boosts yield and quality. Adjust fertilizer type, dosage, and strategies based on growth stages and soil conditions, while observing plant responses. Integrating foliar fertilizers with other nutrients is key to healthy corn development.
