Organic Fulvic Acid Enriched NPK Liquid Fertilizer for Soil Health Improvement

The application of molasses in soil improvement

1.Molasses is naturally rich in organic matter and essential nutrients such as nitrogen, phosphorus, potassium, along with a variety of trace elements, providing a solid basis for use as a high-quality fertilizer.

With simple processing methods, including fermentation with selected microbial strains, sugarcane molasses alcohol byproducts can be converted into a nutrient-rich liquid organic fertilizer.

Vegetable cultivation trials have shown that the application of molasses-fermented organic fertilizer improved flavor quality, increased vitamin levels, and enhanced overall market competitiveness of the produce.

2. Enhance the utilization rate of chemical fertilizers

Molasses can be combined with conventional chemical fertilizers to function as an effective fertilizer efficiency booster.

Its organic constituents are able to form complexes with nutrient ions in the soil, which helps reduce nutrient fixation and leaching losses.

When incorporated into nitrogen fertilizers, molasses improves the soil’s capacity to adsorb and retain nitrogen, allowing nitrogen to be released more gradually and evenly, thereby extending the effective fertilization period.

Rice cultivation trials indicate that nitrogen fertilizers supplemented with molasses achieve a 15%–20% higher nitrogen use efficiency compared with standard nitrogen fertilizers. This improvement allows for reduced nitrogen application rates, lower input costs, and a simultaneous reduction in environmental impact.

3. Enhance the activity of microbial fertilizers

Microbial fertilizers improve the soil ecological environment and enhance soil fertility through the activities of beneficial microorganisms.

Molasses provides abundant carbon sources and energy for microorganisms, which can significantly enhance the activity and reproductive capacity of beneficial microorganisms in microbial fertilizers.

When molasses is added to some microbial fertilizers with Bacillus as the main strain, the number of Bacillus increases significantly in a short period of time, and its ability to decompose insoluble phosphorus and potassium in the soil is significantly enhanced.

The use of microbial fertilizers with molasses added in orchards can effectively increase the content of available phosphorus and potassium in the soil, promote the absorption of nutrients by the root system of fruit trees, and improve the yield and quality of fruits.

4. Develop stress-resistant fertilizers

Molasses shows strong potential as a base material for the development of fertilizers with stress-tolerance functions.

Active compounds in molasses, such as betaine and proline, help improve crops’ ability to withstand environmental stresses.

When molasses is combined with other stress-resistance enhancers, including seaweed extracts and amino acids, innovative formulations of stress-tolerant fertilizers can be developed.

Field applications in arid cotton-growing regions have demonstrated that molasses-based stress-resistant fertilizers significantly improve drought tolerance. Under limited water conditions, cotton plants maintain higher leaf relative water content, exhibit lower wilting rates, and achieve more stable yields.

5. Production of slow-release and controlled-release fertilizers

Slow-release and controlled-release fertilizers are designed to supply nutrients gradually in line with crop growth requirements, helping to minimize fertilizer losses and reduce environmental impact.

By using molasses as a base material and applying physical or chemical modification techniques to form coatings on fertilizer granules, fertilizers with slow and controlled nutrient release properties can be produced.

In this approach, nitrogen fertilizer particles are encapsulated with coating materials formulated from molasses blended with starch and other components.

The nutrient release behavior of these slow- and controlled-release fertilizers can be regulated by soil conditions such as moisture levels and temperature. During the early stages of crop development, nutrient release occurs at a slower rate, matching the lower nutrient demand of young plants.

During the vigorous growth period of crops, the release rate increases, providing sufficient nutrients for the crops.

Application Methods (Reference)

• Silage Application Method: Apply 30–40 kg of molasses solution at 50% concentration per metric ton of forage material, spraying evenly during layering and ensuring thorough compaction.
• Drinking Water Supplementation: Mix molasses liquid into drinking water at a rate of 1%–2%. Ensure the solution is filtered to avoid clogging, helping to reduce heat stress during hot summer conditions.
• Lick Block Formulation: Blend molasses liquid with salt and mineral additives to manufacture liquid lick blocks, with molasses accounting for 30%–40% of the formulation, promoting voluntary intake by cattle and sheep.
