1、Silicon fertilizers, humic acid and their impact on physicochemical
It has been confirmed that silicon (Si) fertilizer and humic acid (HA) could effectively decrease the heavy metals in soil. Nonetheless, the impact of these additives on soil aggregate characteristics was ignored.

These soils which include Oxisols and Ultisols are low in soluble (plant-available) silicon and generally highly leached, acidic, and with low base saturation (Foy 1992).
A Review of Silicon in Soils and Plants and Its Role in US Agriculture
Silicon (Si) is the second most abundant element in the earth’s crust, almost exclusively found in the form of silicon dioxide (SiO 2) in association with a wide array of Si-bearing minerals in crystalline, poorly crystalline, and amorphous phases (Sommer et al., 2006).
Silicon, a quasi
Silicon fertilizer regime, as soil or foliar application, is a subject of debate. Understanding Si uptake mechanisms is crucial for harnessing its positive effects. Diverse mathematical models define Si uptake dynamics at whole plant scale.
What are the differences in application methods between different types
Similar to soil application of the acidic fertilizer, you mix the fertilizer with water and pour it onto the soil. However, because of its alkaline nature, it's great for plants that prefer a slightly higher pH soil, like some types of vegetables.

Of all the major fertilizer nutrients, nitrogen is the main nutrient affecting soil pH, and soils can become more acidic or more alkaline depending on the type of nitrogen fertilizer used.
A Comprehensive Review on the Potential Effect of Silicon Fertilizer
Si transporters are responsible for mediating the movement of Silicon, which is taken up in silicic acid. The amorphous SiO2 structures known as phytolites are generated inside the plant.
Silicon dioxide (SiO₂) water-soluble fertilizer is a common agricultural product, with its primary component being silicon dioxide. Although silicon dioxide itself is an acidic substance, its acidity diminishes when dissolved in water. Consequently, silicon dioxide water-soluble fertilizer typically exhibits neutral or weakly alkaline properties during use.
Understanding the Nature of Silicon Dioxide Silicon dioxide is a colorless, odorless solid with high hardness and melting point. It is insoluble in water but can react with alkalis at high temperatures to form sodium silicate, an important industrial raw material. Additionally, silicon dioxide boasts excellent heat resistance and chemical stability, making it widely applicable in numerous industrial fields.
Behavior in Aqueous Solution When silicon dioxide exists in aqueous solution, it gradually releases hydrogen ions (H⁺). This occurs because the silicon atoms in SiO₂ have weak electronegativity, allowing them to attract electrons and form negative charges. These negative charges attract positively charged ions (e.g., sodium ions, Na⁺) to the surface of silicon dioxide through electrostatic interactions, thereby reducing the acidity of the water. This process, known as protonation, involves water molecules losing a proton to become hydroxide ions (OH⁻).
Impact of Solubility on Acidity Due to its low solubility in water, silicon dioxide’s acidity remains relatively weak. as more silicon dioxide particles dissolve, additional hydrogen ions are released, further lowering the solution’s acidity. Despite this, the dissolved solution retains slight acidity due to the persistent attraction of positive ions to the negatively charged silicon dioxide surface.
Neutral to Weakly Alkaline** In practical use, silicon dioxide water-soluble fertilizer generally appears neutral or weakly alkaline. While its acidity decreases after dissolution, residual acidity persists due to the electrostatic interactions described above.
Usage Precautions
- Avoid mixing with alkaline substances, as this may trigger chemical reactions and reduce fertilizer effectiveness.
- Do not overapply, as excessive use could harm soil quality.
- Follow product guidelines, adhering to recommended dosages.
- Discontinue use immediately and consult professionals if adverse effects occur.
Final Remarks While silicon dioxide water-soluble fertilizer typically leans neutral or slightly alkaline, it still retains minor acidity. Safe and effective application requires adherence to usage instructions and avoidance of excessive dosages.
