1、A review of the foliar application of individual amino acids as
Biostimulants, such as amino acids, offer natural and stable solutions to improve yield, growth, and resistance to external factors. They achieve this by reducing the impact of abiotic stress and stimulating plant defence mechanisms.
2、Amino Acids in Fertilizers: A Wide Range of Applications
Amino acid fertilizers contain various essential amino acids for plants, such as glutamic acid, aspartic acid, and lysine. These amino acids can be directly absorbed and utilized by plants, serving as a nitrogen source and promoting protein synthesis within plants.
3、Seed and Foliar Application of Amino Acids Improve Variables of
The application of amino acids in crops has been a common practice in recent years, although most of the time they are associated with products based on alga...
Effect of foliar application of amino acid, humic acid and fulvic acid
The Results showed that cv. ‘Zard’ had the highest Brix value, fruit protein content, carotenoid, anthocyanins, and phenols, and cv. ‘Arbequina’ had the highest oil fraction.
Amino Acids Biostimulants and Protein Hydrolysates in
The aim of this manuscript is to survey the impacts of amino acids, different types of protein hydrolysates, phenols, and phenolic biostimulants on different plants by presenting case studies and successful paradigms in several horticultural and agricultural crops.
Foliar Absorption and Translocation of Metal
As positive controls, we used stand-alone amino acids and sulfate-based micronutrients. The results showed that under high relative humidity (70–86%), the histidine and glutamate complexes presented transport performance similar to that of sulfates.
Foliar application of amino acid biostimulants increased growth and
The foliar application of amino acids biostimulants, where amino acids serve as the primary active ingredients, emerges as a promising strategy for precisely fulfilling the fertilization requirements of Epipremnum aureum.
Effect of foliar application of amino acid biostimulants on growth
Amino acids biostimulants have been used to improve plant growth, yield and nutrient use efficiency. Data collected from two cultivars were compared to each other. Biostimulants was efficient in enhancing yield and nutritive value which depends on cultivar.
Humic Acid Fertilizer vs Amino Acid Fertilizer: What You Need to Know
Humic acid fertilizer primarily improves soil quality and enhances nutrient uptake by roots, while amino acid fertilizer provides direct nourishment to plants, promoting faster growth and better stress resistance.
A review of the foliar application of individual amino acids as
Mixtures containing multiple amino acids are commonly used in agriculture, but the effects of individual components within these mixtures are less understood. This review summarises current knowledge on the effects of the foliar application of the 20 most common naturally occurring amino acids.
Glutamic acid and amino acid foliar fertilizers are two commonly used plant nutrient supplements in agricultural production. there is no definitive answer to which product is better, as this depends on multiple factors such as crop type, growth stage, soil conditions, and more. Below is a detailed comparison of the two:
1. Composition and Function
- Glutamic Acid: A natural organic acid found in certain bacteria and fungi, it has antibacterial, antioxidant properties and enhances plant disease resistance.
- Amino Acid Fertilizer: A compound fertilizer rich in nitrogen (N), phosphorus (P), potassium (K), and other nutrients, primarily used to supplement essential elements for plants.
2. Application Method
- Glutamic Acid: Typically applied as a liquid spray directly onto plant leaves for rapid absorption.
- Amino Acid Fertilizer: Requires irrigation systems or sprayers. Dosage and frequency depend on specific product guidelines.
3. Applicability
- Glutamic Acid: Suitable for various crops, especially those requiring higher microbial activity (e.g., vegetables, fruits).
- Amino Acid Fertilizer: More effective for cash crops and fruit trees (e.g., cotton, tobacco, grapes, citrus).
4. Cost
- Glutamic Acid: Lower cost due to its primary ingredient (glutamic acid) being widely sourced and inexpensive.
- Amino Acid Fertilizer: Higher price due to its complex nutrient composition and production costs.
5. Safety
- Glutamic Acid: Higher safety, as it contains no harmful substances for humans.
- Amino Acid Fertilizer: Safety varies based on ingredients and manufacturing processes. Poor quality control may lead to residual harmful substances.
6. Environmental Impact
- Glutamic Acid: More environmentally friendly, as its main component has minimal ecological impact.
- Amino Acid Fertilizer: Excessive use may cause soil salinization or other issues.
7. Suitability for Regions
- Glutamic Acid: Preferred in arid or semi-arid regions with poor soil moisture, where plants require additional nitrogen.
- Amino Acid Fertilizer: Better suited for humid or semi-humid regions with fast-growing plants needing密集养分供应.
8. Efficacy
- Glutamic Acid: Effectiveness depends on concentration and frequency of application; higher doses yield better results.
- Amino Acid Fertilizer: Efficacy relies on nutrient balance, crop growth stage, and specific nutritional needs.
Conclusion and Recommendations
Both glutamic acid and amino acid foliar fertilizers have advantages and disadvantages. The choice depends on agricultural conditions, personal preferences, and the following considerations:
- Understand product composition to ensure it meets your needs.
- Evaluate application methods and costs based on regional suitability.
- Prioritize safety and eco-friendliness to avoid environmental or health risks.
- Learn from others’ experiences and test products in practice.
neither product is universally superior. Their performance varies with crop type, growth stage, and soil conditions. Careful research and comparison are essential to achieving optimal agricultural outcomes.
