Enhancing nitrogen use efficiency in agriculture by integrating

The use of organ mineral fertilizers, bio stimulants, and nano fertilizers offers a diversified nutrient supply that supports plant growth under nutrient-deficient conditions. These inputs improve nutrient availability and soil health, with bio stimulants boosting root development and nano fertilizers providing controlled-release nutrient delivery.

Enhanced Efficiency Fertilizers:

Improved fertilizer use efficiency for nitrogen comes from the plant capturing more of the N applied as fertilizer as well as any residual nitrate in the soil. Loss of N from the system contributes to lower N use efficiency.

Global impact of enhanced

NIs and PCU (EEFs) significantly enhanced vegetable yield and quality based on a global meta-analysis. NIs were more effective for N 2 O reduction while PCU was better for reducing total N losses. Yield-enhancing effect of NIs and PCU were greater at low soil available N and SOC contents.

Advances in Nitrogen Use Efficiency of N

eased nitrogen fertilizer use and better nitrogen management have been the main drivers of significant increases in global food production. However, the eficiency of nitrogen use in modern agroecosystems remai s low, with more than half of nitrogen fertilizers lost from the plant-soil system and released into the environ-ment (Mahmud et al

Novel nitrogen fertilizer efficiency enhancers are additives developed through chemical or biotechnological means to improve the effectiveness of nitrogen fertilizers. These additives typically contain multiple components aimed at enhancing nitrogen utilization, reducing environmental pollution, and boosting crop yield and quality. Below are some common types of novel nitrogen fertilizer enhancers and their primary components:

1. Urease Inhibitors: Urease inhibitors are chemicals that suppress the activity of urease, an enzyme in soil responsible for breaking down urea into ammonia. By slowing urea decomposition, these inhibitors improve nitrogen fertilizer efficiency. Common urease inhibitors include ammonium acetate, copper sulfate, and others.

2. Microbial Fertilizers: Microbial fertilizers contain beneficial microorganisms, such as nitrogen-fixing bacteria, phosphate-solubilizing bacteria, and potassium-releasing bacteria. These microbes help fix nitrogen, phosphorus, and potassium in soil, reducing reliance on chemical fertilizers. Examples include rhizobium inoculants (for legumes) and phosphate-solubilizing bacterial agents.

3. Organic-Inorganic Compound Fertilizers: These fertilizers combine organic matter (e.g., humus, compost) with inorganic salts (e.g., nitrogen, phosphorus, potassium). The organic component improves soil structure and nutrient supply, while the inorganic component provides essential elements. Examples include humic acid compound fertilizers and mixed organic-inorganic blends.

4. Slow-Release Nitrogen Fertilizers: Slow-release nitrogen fertilizers deliver nitrogen gradually to plants, reducing nutrient loss and environmental impact. Common forms include coated urea (urea encapsulated in a protective layer) and controlled-release urea (chemically modified to delay nitrogen release).

5. Biopesticides: Biopesticides utilize natural bioactive substances, such as microbial pesticides (e.g., Bacillus subtilis) or botanical pesticides (e.g., neem oil), to control pests and diseases. By reducing synthetic pesticide use, they minimize environmental harm.

6. Plant Growth Regulators (PGRs): PGRs are chemicals that regulate plant growth and development. Examples like gibberellins (promote stem elongation) and cytokinins (delay senescence) can enhance crop yields and quality when used appropriately.

Novel nitrogen fertilizer enhancers encompass urease inhibitors, microbial fertilizers, organic-inorganic blends, slow-release formulas, biopesticides, and plant growth regulators. These components can be combined scientifically to optimize fertilizer efficiency, reduce environmental risks, and improve crop productivity. When selecting and applying these enhancers, it is crucial to follow scientific principles and ensure rational compatibility for best results.
