Details

Ultra HumiMax DF is made from young leonardite from high-quality mining areas, utilizing the DF high-tower spray drying process. It also incorporates various mineral nutrients essential for plant growth, possessing high activity and resistance to hard water. It can significantly improve soil structure, promote root growth, regulate the soil microbial environment, and enhance crop quality.

Benefits

• Reduces soil salinity and EC levels, optimizing the root-zone environment and alleviating salt stress.
• Regulates soil pH in both directions, helping maintain a balanced and crop-friendly rhizosphere.
• Improves fertilizer utilization efficiency, controlling nitrogen loss, activating phosphorus, and enhancing potassium availability.
• Mobilizes fixed macro- and micronutrients, reducing nutrient fixation and loss while lowering fertilizer input costs.

• Stimulates beneficial microbial activity, providing a high-activity carbon source that supports microbial reproduction and a healthy soil ecosystem.
• Enhances crop growth, stress tolerance, and quality, supporting root development, photosynthesis, and stable, high-quality yields.
• Increases soil organic matter, improving soil physical and chemical properties and restoring overall soil vitality.
• Promotes stable soil aggregate structure, enhancing aeration, water-holding capacity, and resistance to compaction and erosion.

Field Application Cases

Tomato: After application of ULTRA HUMIMAX-DF, tomato seedlings exhibit robust vegetative growth with thicker stems, well-developed leaves, and a stronger root system, supporting uniform and vigorous early establishment.

Apple: After application, apple fruits show improved enlargement and more even color development during the fruit maturation stage, with firmer texture and enhanced sugar content, significantly improving overall fruit quality.

Potato: After application, potato plants develop a dense and healthy root system, promoting efficient nutrient uptake, leading to larger tubers, improved yield, and more uniform tuber size.
