Monosilicic acid [Si (OH)4] is the only plant-available form of silicon (PAS) present in the soil. The ability of a plant to uptake Si is positively correlated with the PAS concentration of the soil.

2、Silicon as a Smart Fertilizer for Sustainability and Crop

In this review, we provide an overview of different smart fertilizer types, application of Si fertilizers in agriculture, availability of Si fertilizers, and experiments conducted in greenhouses, growth chambers, and open fields.

3、概念

硅酸盐指的是含硅的化合物，如硅酸钙（CaSiO3）和硅酸镁（MgSiO3）。 硅酸或单硅酸（Si (OH)4 或 H4SiO4）是土壤中唯一可溶且植物可利用的硅形式，也是植物能直接吸收的唯一硅形式。 硅虽然未被归类为大多数植物的必需元素，但已被证明在加入肥料时对许多作物有益。 然而，当硅加入土壤中时，它对植物也能起到有益的作用。 大多数植物可以吸收与常量营养元素相当量的硅。 随着植物体内硅浓度的增加，它有助于提高植物的机械强度。 硅可以通过提高植物的防御反应来保护植物免受害虫攻击、疾病和环境压力。 硅增加通气性并减少淋失。 增加免疫力，水分和矿物质的平衡。 增强细胞壁强度和植物强度。

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

To be an effective source for crops, a silicon fertilizer should provide a high percentage of silicon in soluble form. Other characteristics to consider are cost of material, physical properties, and ease of application.

5、The Use of Si

Silicon (Si) is a “ quasi-essential ” element, associated to stresses/limitations alleviation in crops. However, stressful situations are becoming the norm, due to climate change, human exhaustion of natural resources, land degradation and loss of soil biodiversity.

Using Silicon for Plants: A How

Silicon fertilizers can be alkaline, increasing the pH of stock solutions, which may reduce the solubility of micronutrients and cause precipitation, so using separate stock tanks for silicon and standard fertilizers is an advisable practice.

Silicon fertilizer is a nutrient product containing silicon, primarily used to replenish silicon levels in the soil. Silicon is one of the essential microelements for plant growth and plays a critical role in the development and health of plants. It improves soil structure, enhances air permeability and water-retaining capacity, promotes root development, and strengthens disease resistance and drought tolerance in plants.

Main Sources of Silicon Fertilizers:

1. Natural Silicon Fertilizers: Abundant silicate minerals in nature, such as quartz, feldspar, and mica, release silicon during weathering. Examples include raw materials like quartz sand, feldspar, and mica.
2. Synthetic Silicon Fertilizers: Chemically produced compounds like sodium sulfate (Na₂SO₄) and sodium silicate (Na₂SiO₃) serve as artificial sources of silicon.
3. Plant-Derived Silicon: Certain plants secrete organic silicon compounds (e.g., silicates, silica phenolics) during growth. These degrade biologically and enrich the soil with silicon.

Key Functions of Silicon Fertilizers:

1. Soil Structure Improvement: Silicon combines with soil minerals to form stable silicates, enhancing soil air permeability and water retention—crucial for root growth and water uptake.
2. Root System Development: By improving water retention, silicon facilitates efficient water absorption and encourages root expansion for better nutrient/water uptake.
3. Disease Resistance: Silicon strengthens plant immunity, reducing vulnerability to pests and diseases.
4. Drought Tolerance: Silicon reduces leaf transpiration, minimizing water loss and boosting drought resilience.
5. Photosynthesis Efficiency: Silicon influences chlorophyll synthesis, optimizing photosynthetic processes.
6. Nutritional Value: It modulates enzyme activity, promoting healthy growth and nutrient synthesis.
7. Growth Promotion: Silicon regulates hormone synthesis and transport, accelerating developmental stages.
8. Yield and Quality Enhancement: By optimizing metabolic processes, silicon increases crop yields and improves produce quality.

silicon fertilizers are vital for soil health and plant vitality. Proper use enhances soil properties, root strength, stress resistance, and ultimately leads to higher-quality, more productive crops.
