1、Humic and fulvic acids as biostimulants in horticulture

In this review we define humic substances in a horticultural context. Their effects on nutrient uptake and plant metabolism are then discussed and a general schematic model of plant-humic responses is presented.

2、Incorporation of humic

So, we consider in this review the incorporation into compound NPK fertilizer granules of molecules containing HS with the ability to improve the root uptake of some mineral nutrients.

3、Fulvic Acid (FA) for Enhanced Nutrient Uptake and Growth: Insights from Biochemical and Genomic Studies

Among several agronomic inputs such as soil amendments, fertilizer application, and plant growth regulators, we found that foliar application of fulvic acid (FA), one of the most bioactive humate molecules, enhanced K levels in leaves.

4、Effect of fulvic acids on the electrolytes physiology in vertebrates

Empiric results show evidence of faster growing, higher average weight and better resistance to viral infections.

Effect of fulvic acids with different characteristics on biological denitrification

It was found that SAFA remarkably enhanced the denitrification performance, while SRFA and PPFA had no obvious effect.

The Possibility of Organo

Organo-mineral fertilizers (OMFs) derived from biosolids can significantly reduce costs of sewage sludge disposal. Different technologies are developed for disinfection, sterilization and nutrient-enrichment of sewage sludge in order to use it for balanced granulated fertilizers.

Reactions of boron with soils

Boron is an essential micronutrient for plants, but the range between deficient and toxic B concentration is smaller than for any other nutrient element. Plants respond directly to the activity of B in soil solution and only indirectly to B adsorbed on soil constituents.

Effects of the continuous use of organic manure and chemical fertilizer on soil inorganic phosphorus fractions in calcareous soil

Evidence from many studies in similar fields worldwide 1, 2 clearly indicates the advantages of OM, which include reducing the use of CF, preventing non-point source pollution, improving soil...

Humic acids: Structural properties and multiple functionalities for novel technological developments

HAs differ from the other HS fractions (fulvic acid and humins) in that they are soluble in alkaline media, partially soluble in water, and insoluble in acidic media.

Phosphorus fertilizer recovery from calcareous soils amended with humic and fulvic acids

Application of the humic-fulvic acid mixture (HFA) increased the amount of applied P recovered as Olsen P in all the soils except in one soil with the highest Na saturation.

Mineral-derived fulvic acid potassium and boron fertilizer both play important roles in agricultural production, each with unique advantages and suitable applications. Below is a detailed comparison of the characteristics of these two fertilizers to help you make a more informed decision.

I. Characteristics of Mineral-Derived Fulvic Acid Potassium

1. Soil Improvement: Fulvic acid potassium is a natural organic substance that enhances soil structure and increases water- and nutrient-retention capacity. It promotes better absorption of minerals in the soil, improving soil fertility.

2. Plant Growth Promotion: Rich in organic matter and trace elements, fulvic acid potassium directly or indirectly stimulates plant growth. It provides essential nutrients and helps plants resist pests and diseases.

3. Stress Resistance: Soils treated with fulvic acid potassium enhance plants' resilience to adverse conditions (e.g., drought, salinity), improving growth under challenging environments.

4. Eco-Friendly: As a natural substance, fulvic acid potassium is non-polluting and safe for use as an organic fertilizer in agriculture.

5. Versatile Application: Suitable for various crops, including grains, cash crops, fruits, and vegetables.

II. Characteristics of Boron Fertilizer

1. Plant Growth Promotion: Boron fertilizer significantly boosts plant growth, especially for boron-demanding crops like rape and cotton. It improves photosynthesis efficiency and stress resistance.

2. Yield Increase: Noticeably enhances crop yields, particularly in boron-deficient soils. It strengthens flower bud differentiation and overall plant health.

3. Quality Improvement: Enhances crop taste, nutritional value, and disease resistance while reducing pest susceptibility.

4. Easy Application: Simple to use—applied directly to soil or via irrigation after dissolving in water.

5. Cost-Effective: Lower cost compared to other fertilizers, making it budget-friendly for farmers.

III. Comparative Analysis of Mineral-Derived Fulvic Acid Potassium and Boron Fertilizer

1. Soil Improvement: Fulvic acid potassium offers comprehensive soil enhancement, including improved structure and nutrient retention, while boron fertilizer focuses more on plant growth and yield.

2. Cost Considerations: For prioritizing yield and quality, fulvic acid potassium is a cost-effective, long-lasting option. boron fertilizer is preferable if enhancing disease resistance is critical.

3. Application Methods: Fulvic acid potassium can be applied via irrigation or mixed with other fertilizers, whereas boron fertilizer typically requires simple soil sprinkling.

4. Environmental Impact: Fulvic acid potassium is naturally eco-friendly, while boron fertilizer may pose minor environmental risks under specific conditions.

Both mineral-derived fulvic acid potassium and boron fertilizer have distinct strengths. The choice depends on crop requirements, soil conditions, and budget constraints. Fulvic acid potassium is ideal for yield, quality, and sustainability, while boron fertilizer excels in disease resistance and affordability. Always apply fertilizers rationally to avoid waste and environmental harm.
