The effect of ammonium nitrogen fertilizers on maize yield is a complex process involving multiple biological and ecological factors. Below is a detailed analysis of how these fertilizers influence maize production:

I. Promoting Maize Growth

1. Providing Essential Nutrients

Ammonium nitrogen fertilizers directly supply nitrogen to maize plants, a critical macronutrient for growth. Nitrogen is indispensable for protein synthesis and plays a vital role in physiological processes such as cell division, elongation, and maturation. Adequate nitrogen availability significantly enhances maize growth.

2. Enhancing Photosynthesis

Nitrogen acts as a cofactor in photosynthesis, increasing chlorophyll content and activity. This boosts the photochemical efficiency of maize leaves, enabling them to produce more glucose and organic compounds. Ammonium fertilizers thus improve energy availability for plant development.

3. Stimulating Root Development

Ammonium nitrogen fertilizers promote root growth, enhancing the plant’s ability to absorb water and nutrients. A robust root system ensures efficient uptake of soil nutrients, supporting maize growth throughout its lifecycle.

4. Improving Stress Resistance

Optimal use of ammonium fertilizers strengthens maize’s resistance to pests and diseases. Nitrogen aids protein synthesis, improving overall plant health, which in turn enhances tolerance to environmental stresses.

II. Impact on Maize Quality

1. Increasing Protein Content

Ammonium-based fertilizers elevate protein levels in maize kernels, a key determinant of quality. Higher protein content enhances nutritional value and market appeal.

2. Enhancing Taste and Texture

Kernels with elevated protein often exhibit better taste and texture, meeting consumer preferences for high-quality produce.

3. Reducing Aflatoxin Risks

Excessive use of ammonium fertilizers may increase aflatoxin levels in kernels, posing food safety risks. Controlled application is crucial to minimize this hazard.

4. Balancing Amino Acid Profiles

Proper dosage of ammonium fertilizers promotes balanced amino acid composition, contributing to improved nutritional quality and market competitiveness.

III. Environmental and Economic Effects

1. Reducing Fertilizer Runoff

Compared to urea, ammonium fertilizers release nitrogen slowly, reducing soil leaching and environmental pollution.

2. Economic Benefits

Higher yields from ammonium fertilizers increase farmer income. Premium prices for high-quality maize further enhance profitability.

3. Supporting Sustainable Agriculture

Rational use of ammonium fertilizers aligns with sustainable farming practices. Scientific application minimizes environmental harm, preserves soil health, and ensures long-term agricultural viability.

4. Market Competitiveness

High-quality maize produced with ammonium fertilizers meets consumer demands, strengthening market position and fostering competitive advantage.

Ammonium nitrogen fertilizers positively impact maize yield by promoting growth, improving quality, and mitigating environmental burdens. optimal results depend on soil-specific and stage-appropriate application. Farmers should avoid overuse to prevent adverse effects. Scientific fertilization practices are key to achieving sustainable agricultural goals.
