Cation Exchange Capacity (CEC) is a critical parameter reflecting a soil’s ability to retain and exchange positively charged nutrient ions (e.g., Ca²⁺, Mg²⁺, K⁺, NH₄⁺), essential for plant growth. A higher CEC enhances soil fertility by reducing nutrient leaching, stabilizing pH, and improving microbial activity. For instance, soils rich in clay minerals like montmorillonite (CEC: 100–150 cmol/kg) or organic matter (CEC: 100–300 cmol/kg) exhibit superior nutrient retention compared to sandy soils with low CEC. CEC also mitigates heavy metal toxicity by binding harmful cations (e.g., Cd²⁺, Pb²⁺), thereby protecting groundwater and soil health.

Impact of Khumic E+ Potassium Humate Granules​​

Khumic E+, composed of humic acids and potassium, significantly enhance CEC through multiple mechanisms:

Organic Matter Enrichment: They increase soil organic carbon, which provides additional negatively charged exchange sites for cations, boosting CEC by up to 20% in degraded soils.

Soil Structure Improvement: By promoting soil aggregation, they enhance porosity, water infiltration, and root access to nutrients.

Nutrient Synergy: The potassium in humate granules binds to exchange sites, improving K⁺ availability for plants while reducing leaching.

pH Buffering: Humic acids stabilize soil pH, optimizing conditions for cation exchange and microbial activity.

Khumic AMINO-L amino acid organic liquid fertilizer 350g/L + Ca ,Mg,S,Te etc Trace elements for fruit trees

- Khumic AMINO-L amino acid organic liquid fertilizer Promote growth and development: Amino acids are the basic units that make up proteins, which can provide fruit trees with rich nutrients, promote the growth of roots of fruit trees, make the root system more developed, and enhance the root system's absorption capacity of water and nutrients.  At the same time, it helps the growth of new shoots and the development of leaves, makes the leaves greener and thicker, improves photosynthesis efficiency, and provides sufficient energy and matter for the growth of fruits.

 - Improve fruit quality: It can promote the expansion of the fruit and make the fruit even in size.  At the same time, increase the sugar content of the fruit and enhance the taste and flavor of the fruit.  It can also improve the color of the fruit, make the appearance of the fruit more vivid, and increase the product value of the fruit.

 - Enhance the stress resistance of the tree: Enhance the adaptability of fruit trees to adverse environmental conditions such as drought, high temperature, and low temperature.  Improve the disease resistance of fruit trees, reduce the occurrence of pests and diseases, reduce the use of pesticides, and ensure the quality and safety of the fruit.

EDDHA Fe: An excellent choice for supplementing iron nutrition for crops

1. High-efficiency iron supplementation

EDDHA Fe, with its special chemical structure, can tightly chelate with iron ions to form a stable complex that is easily absorbed by plants. Even in complex soil environments, it can effectively prevent the precipitation and fixation of iron ions, continuously provide plants with available iron nutrition, and quickly relieve plant iron deficiency symptoms.

2. Super stability, adaptable to diverse environments​

The chelating ability of EDDHA Fe can work stably in a wide pH range (pH 3-12), and can be used in acidic and alkaline soils.

3. Green and environmentally friendly, helping sustainable development​

EDDHA Fe has stable chemical properties, is not easy to remain and accumulate in the soil, and will not cause any negative impact on the soil ecological environment.
