2、Impacts of nitrogen (N), phosphorus (P), and potassium (K) fertilizers

Soil nutrient deficiency is one of the significant challenges in grain production, particularly nitrogen (N), phosphorus (P), and potassium (K). These deficiencies not only reduce crop yields but also cause associated environmental issues, such as soil structure deterioration and ecosystem services diminution.

Fertilization significantly increased maize yield, with the greatest increase occurring in the treatment combining common and slow-release N. Among all the treatments receiving equal N amounts,...

Effects of different nitrogen fertilizer types and application rates on

Compared with traditional N application, slow-release N application significantly increased grain yield by 1.3–10%, mainly due to higher aboveground N uptake (5.1–12.1%) and N use efficiency (8–48.2%) (Xia et al. 2017).

Nitrogen Fertilizers and Stabilizers for Corn Production

Nitrogen (N) fertilizer is a critical input in corn production. One of the most challenging aspects of successfully managing nitrogen is the fact that nitrogen from fertilizer can be lost from the soil before the corn crop is able to take it up.

Substituting partial chemical nitrogen fertilizers with organic

Replacing partial chemical nitrogen (N) fertilizers with SP is more conducive to achieving stable and high crop yields (Burke et al., 2022; He et al., 2022b). SP mainly includes animal manure, crop residues, and industrial and urban wastes.

The Effect of Different Tillage Methods and Nitrogen Chemical

In order to investigate the effect of tillage and nitrogen fertilizer on photosynthetic pigments and quantitative and qualitative traits of corn grain, an experiment was conducted in the research farm of Islamic Azad University, Chalous Branch, Mazandaran Province, Iran, in 2016 and 2017.

The differences between corn-specific fertilizer and nitrogen fertilizer primarily lie in their crop applicability, mechanisms of action, ingredients, and effects. Below is a detailed explanation:

1. Crop Applicability:

   • Corn-specific fertilizer: Designed for crops like corn (gramineous plants), its formulation balances essential nutrients (e.g., nitrogen, phosphorus, potassium) to meet the nutritional needs of corn throughout its growth stages.
   • Nitrogen fertilizer: Widely used for various crops, including corn, but prioritizes nitrogen supply, especially during early plant development.

2. Mechanisms of Action:

   • Corn-specific fertilizer: In addition to nitrogen, it may contain micronutrients, secondary macronutrients (e.g., magnesium, sulfur), organic matter (e.g., humic acid), and other components to enhance soil water/nutrient retention, root development, and nutrient absorption efficiency.
   • Nitrogen fertilizer: Primarily boosts leaf growth and photosynthetic efficiency by providing nitrogen.

3. Ingredients:

   • Corn-specific fertilizer: Tailored to regional and crop needs, it often includes phosphorus, potassium, magnesium, sulfur, organic matter, and trace elements.
   • Nitrogen fertilizer: Typically a single-source nitrogen product, such as urea or ammonium nitrate.

4. Effects:

   • Corn-specific fertilizer: Its diverse formulation supports corn’s nutritional needs at different growth stages, improving yield and quality. Organic matter and micronutrients also enhance soil structure and reduce nutrient runoff.
   • Nitrogen fertilizer: Rapidly increases plant nitrogen levels and promotes growth, but excessive use can lead to soil salinization, degradation, and environmental harm.

5. Application Methods:

   • Corn-specific fertilizer: Applied as granules or powders, often diluted based on crop requirements.
   • Nitrogen fertilizer: Directly spread on soil or dissolved in water for application.

6. Economic Efficiency:

   • Corn-specific fertilizer: Targeted nutrition reduces waste and improves long-term economic benefits.
   • Nitrogen fertilizer: Lower short-term costs, but overuse leads to resource waste and environmental risks.

7. Environmental Impact:

   • Corn-specific fertilizer: Minimizes ecological harm by reducing pollutants (e.g., preventing water contamination from nutrient runoff).
   • Nitrogen fertilizer: Excessive use causes soil acidification, groundwater contamination, and ecosystem damage.

Corn-specific fertilizer and nitrogen fertilizer differ significantly in ingredients, mechanisms, and crop applicability. The former focuses on balanced nutrition for corn’s growth, while the latter prioritizes nitrogen for early development. When selecting fertilizers, consider crop-specific needs and soil conditions to optimize results.
