1、2024 Field Research Report Foliar fertilizers in Corn 2024

Foliar applied nutrients have been used to supplement soil applied nutrients in corn. Nitrogen, phosphorus, potassium, iron, and sulfur are nutrients that can potentially improve corn yield when applied as a foliar treatment.

2、Efficiency of Corn Foliar Fertilizing at Different Developmental Stages

The effectiveness of foliar fertilization of corn in the phase of five and eight leaves with the Batr Zinc fertilizer (1.0 L/ha) was studied in the variants without traditional application of fertilizers and with soil treatment with nitrogen (N 30) and complete mineral (N 30 P 30 K 30) fertilizers.

3、Foliar Fertilization of Corn with Mono

The objective of this work is to determine the impact of applying mono-potassium phosphate (MKP) and urea fertilizer to corn foliage at several growth stages on grain yield and grain components.

Facts on Foliar Feeding of Corn and Soybeans

This Field Facts provides an objective discussion of foliar feeding of corn and soybeans.

Foliar feeding of corn / maize – the way to achieve better crops

After male inflorescence the plant nutrient uptake from leaf and soil is reduced to minimum, and the plant consists on the former feeding given from 7-9 leaves (50 cm) to 14 leaves (1.5 m), therefore it is important to supply N and K in this critical stage.

Is There a Point of No Return? When Is It Too Late to Fertilize Corn?

Discover the best timing for fertilizing corn with our comprehensive guide on when it's too late to apply fertilizers. Learn about the crucial growth stages and how proper fertilization can impact your corn yield.

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.

Foliar Fertilizers in Corn

Guide to Foliar Fertilization: Best Practices, Dosages, and Benefits

Compared to traditional soil fertilization, foliar feeding offers faster absorption, higher nutrient use efficiency, and more targeted results.

Corn, as one of the world’s major food crops, attracts significant attention regarding its yield and quality. During its growth, foliar fertilization serves as an efficient nutrient supplement, rapidly replenishing essential nutrients and promoting healthy development. selecting appropriate foliar fertilizers is critical to enhancing corn productivity and quality. Below is a detailed guide to suitable foliar fertilizers and application methods for late-stage corn.

I. Selection and Timing of Foliar Fertilizers

1. Potassium Dihydrogen Phosphate

• Primary Function: Supplies phosphorus and potassium, fostering root development and improving disease resistance.
• Application Method: Apply a solution containing 0.5–1 kg per mu during the mid-to-late growth stages. Spray in the early morning or late evening to avoid heat stress.
• Precautions: Adjust dosage and concentration based on local soil pH variations.

2. Microelement Fertilizers

• Primary Function: Replenishes micronutrients (e.g., iron, zinc, manganese), enhancing stress resistance and growth.
• Application Method: Spray a solution with 0.3–0.5 kg per mu, preferably in the morning or evening.
• Precautions: Choose micronutrient-rich formulas and avoid incompatible mixing with other fertilizers.

3. Bio-Fertilizers

• Primary Function: Microbial-based fertilizers that improve soil structure, boost fertility, and aid nutrient absorption.
• Application Method: Apply a solution with 0.2–0.5 kg per mu, timing sprays for early morning or late evening.
• Precautions: Select strains suited to local climatic conditions for optimal results.

II. Application Techniques for Foliar Fertilizers

1. Uniform Spraying

• Importance: Ensures even coverage to prevent localized overdosing and leaf burn.
• Method: Shake the solution well before use. Target leaves directly, avoiding stems.

2. Control Spray Timing

• Importance: Maximizes absorption by aligning with plant physiological rhythms.
• Method: Apply during cool periods (morning/evening) when leaves are turgid. Avoid midday heat to prevent foliage damage.

3. Combine with Other Fertilization Methods

• Importance: Integrates foliar spraying with base fertilizers (applied initially) and topdressing (supplementary) for synergistic effects.
• Method: Coordinate foliar applications with soil-based fertilization schedules.

III. Precautions and Recommendations

1. Soil Testing

• Importance: Guides fertilizer selection by identifying nutrient deficiencies.
• Method: Conduct soil tests before applying foliar fertilizers to tailor nutrient inputs.

2. Rational Fertilizer Combinations

• Importance: Balances macro- (N, P, K) and micronutrients for optimized uptake.
• Method: Adjust fertilizer types and ratios based on corn growth stages and soil tests.

3. Monitor Crop Responses

• Importance: Allows timely adjustments to avoid adverse effects.
• Method: Observe plants post-application; address abnormalities promptly.

4. Safety Protocols

• Importance: Protects both crops and applicators.
• Method: Follow product guidelines, wear protective gear, and avoid direct skin contact.

Choosing the right foliar fertilizer is vital for late-stage corn development. By combining scientific selection, proper timing, and safety measures, farmers can maximize yields and quality. Integrating foliar sprays with other fertilization practices ensures comprehensive nutrient support for robust crop growth.
