1、Understanding the Role of Humic Acids on Crop Performance and Soil Health
HS are classified as humic acids (HA), fulvic acids (FA), and humins based on their solubility in water, acidic or alkaline solutions (De Melo et al., 2016).
2、Humic Acid Fertilizer Improved Soil Properties and Soil Microbial
It was found that humic acid increased soil nutrient contents, including the total soil nitrogen, total phosphorus, total potassium, available nitrogen, available phosphorus, available...
3、Humic Acid: The Science of Humus and How it Benefits Soil
Humic acid is a group of molecules that bind to, and help plant roots receive, water and nutrients. High humic acid levels can dramatically increase yields. Humic acid deficiency can prevent farmers and gardeners from growing crops with optimum nutrition.
4、Effect of Humic substances on soil properties and crop production: A
Humic acid is an eco-friendly product needed in lesser quantity when compared to other chemical fertilizers and manures. Humic Acid can be integrated into the soils in the form of manure, it improves the physical properties of the soil.
5、(PDF) Properties of Humic Acid Substances and Their Effect in Soil
Humus is categorised according to their molecular weights and solubility into humus, humic acids and fulvic acids. Humic substances are the organic material naturally present in soil.
Humic Acid and Returning Soil To A Healthy State
Humic Acid and the Role of Ionization in Soil Structure, Drainage and Water Retention three basic types: Clay, Silt (Loam), and Sandy. Most agricultural soils are a combination of the three types in varying degrees of content depending on your geographic area and how luck
Humic Acid: Unleashing the Potential of Your Garden Soil
While humic acid itself does not provide nutrients, its presence significantly influences nutrient dynamics in the soil. It has a unique capacity to chelate, or bind, nutrients, making them more accessible to plant roots.
Humic, fulvic and ulmic acids and their use in agriculture
Incorporating humic, fulvic, and ulmic acids into agricultural practices can enhance soil fertility, nutrient availability, and overall plant health, ultimately leading to increased crop yields and improved sustainability.
Humic Acid Fertilizer: What It Is and Its Key Benefits
Humic acid molecules are larger and less water-soluble, especially under acidic conditions. Its primary benefits include improving soil structure, enhancing nutrient retention, and stimulating microbial activity. Humic acid works mainly within the soil matrix, aggregating soil particles and increasing water-holding capacity.
How to Use Humic Acid as a Soil Supplement
Humic acid is not a single chemical compound but rather a broad category of molecules that improve soil quality by enhancing nutrient availability, water retention, and microbial activity. It exists naturally in peat, lignite (a low-rank coal), leonardite (an oxidized form of lignite), and compost.
Humic acid-enriched nutrient soil is a modified soil type that improves soil structure, physicochemical properties, and plant growth conditions by incorporating humic acid and other organic materials. This soil variant has gained widespread application in agricultural production.
Humic Acid: Origins and Functions Humic acid is a natural organic matter formed through microbial decomposition and mineralization of animal and plant residues. Its high fertility and water-retaining capacity effectively enhance soil physical and chemical properties. In agriculture, humic acid is extensively used in fertilizers, pesticides, soil conditioners, and related fields.
Production Process of Humic Acid Nutrient Soil
- Raw Material Preparation: Collect humic acid and organic fertilizers (e.g., chicken manure, cow dung, pig manure) through fermentation or composting.
- Uniform Mixing: Blend materials in specific ratios, controlling temperature and humidity to ensure thorough reaction.
- Granulation: Shape the mixture into particles using extrusion or spraying methods.
- Drying: Reduce moisture content for easy storage and transport.
- Packaging and Storage: Seal dried soil in a dry, ventilated area to prevent dampness and contamination.
Advantages of Humic Acid Nutrient Soil
- Enhanced Fertility: Rich in organic matter, it provides essential nutrients for plants.
- Improved Soil Structure: High water retention and aeration create loose, fertile soil.
- Root System Promotion: Increases nutrient availability, fostering robust root growth and disease resistance.
- Pest and Disease Reduction: Inhibits soil pathogens and pests, boosting plant resilience.
- Extended Growth Period: Stabilizes soil temperature and humidity, prolonging crop development.
- Eco-Friendly Fertilization: Partially replaces chemical fertilizers, reducing environmental pollution and production costs.
Humic acid-enriched nutrient soil is a modified soil optimized for plant growth through organic matter addition. Its applications in agriculture significantly improve soil health, promote crop yields, reduce chemical inputs, and support environmental sustainability. As agricultural technology advances, its adoption will continue to drive productivity and ecological benefits.
