1、Silicon, a quasi

Silicon is absorbed by plant roots, then transported through cortical cells to the stele, and subsequently translocated to various shoot tissues through the transpiration stream where it gets polymerizes into amorphous silica (SiO2) (Mandlik et al., 2020; Ma et al., 2011).

2、Silicon as a Smart Fertilizer for Sustainability and Crop

Silicon (Si), despite being abundant in nature, is still not considered a necessary element for plants. Si supplementation in plants has been extensively studied over the last two decades, and the role of Si in alleviating biotic and abiotic stress has been well documented.

3、Silicon addition improves plant productivity and soil nutrient

Silicon (Si) plays an important role in plant nutrient capture and absorption, and also promotes plant mechanical strength and light interception in alpine meadows.

The Mechanism of Silicon Transport in Plants

Silica or silicon dioxide (SiO 2) are glass-like compounds that are insoluble and not absorbed by plants. Silicic acid [Si (OH) 4] is absorbed by plant roots and transported to intercellular spaces for deposition (Epstein 2009).

Silicon Influences Soil Availability and Accumulation of Mineral

Silicon (Si) effects on mineral nutrient status in plants are not well investigated. It is known that Si has a beneficial effect on plants under stressed conditions.

FS1278: Silicon Needs of Soils and Crops (Rutgers NJAES)

Silicon is beneficial to many crops when added to some soils as a fertilizer. It is not classified as an essential element for most plants but horsetail (Equisetum) and some types of algae cannot survive without a supply of silicon from the environment.

Silicon acquisition and accumulation in plant and its significance for

Although silicon (Si) is ubiquitous in soil and plant, evidence is still lacking that Si is essential for higher plants. However, it has been well documented that Si is beneficial for healthy growth of many plant species.

Silicon Fertilizer Benefits for Crops

Silicon fertilizers supply plant-available forms of Si—most commonly as monosilicic acid (H₄SiO₄), calcium silicate, or potassium silicate. These compounds are absorbed by roots and deposited in cell walls, creating a physical barrier against stress and pathogens.

Silicon, a quasi

Silicon plays a pivotal role in alleviating the biotic and abiotic stress in plants by acting as a physical barrier as well as affecting molecular pathways involved in stress tolerance, thus widely considered as “quasi-essential”.

A Comprehensive Review on the Potential Effect of Silicon Fertilizer

Silicon. Nevertheless, plants get advantages from the presence of Silicon, and it has been shown that Si may boost the plant's resistance to both biotic and abiotic challenges, providing the plant with protection and stability.

Silicon fertilizer is a critical nutrient for plant growth and development, playing a vital role in their physiological processes. The ease with which plants absorb silicon fertilizer can be attributed to several key factors:

1. Form of Silicon Fertilizer: Silicon fertilizer typically exists in the form of silicates, which are more readily absorbed by plants. The silicon in silicates primarily occurs as silicate ions, a form that is easily uptaken by plant cells.

2. Solubility of Silicon Fertilizer: Silicon fertilizer exhibits relatively high solubility in soil, facilitating its absorption by plants. The considerable water solubility of silicates ensures efficient uptake by root systems.

3. Bioavailability of Silicon: The bioavailability of silicon fertilizer—the extent to which it is utilized within plants—is high. Research indicates that silicon is effectively metabolized by plants, thereby promoting growth.

4. Chemical Properties of Silicon: The chemical nature of silicon fertilizer enhances its absorbability. Its low reactivity prevents rapid interaction with plant roots, reducing nutrient loss. Additionally, silicon acts as a buffer, regulating soil pH to create an optimal environment for plants.

5. Fertilization Methods: Proper application techniques improve silicon utilization. Combining silicon fertilizer with organic matter increases its efficacy, while integrating it with phosphorus, potassium, or other nutrients amplifies its benefits.

6. Application Rate: Optimal dosages of silicon fertilizer maximize absorption. Excessive use may elevate soil silicon levels to toxic concentrations, hindering normal plant growth. Thus, application rates should align with soil conditions and crop requirements.

7. Timing of Application: Applying silicon fertilizer during early growth stages, when root systems are robust, enhances uptake. Supplemental applications during peak growth periods ensure adequate silicon supply to support development.

the efficient absorption of silicon fertilizer depends on its form, solubility, bioavailability, chemical properties, application methods, dosage, and timing. By adopting scientific fertilization practices, plants receive ample silicon to boost yields and improve crop quality.
