A Comprehensive Review on the Potential Effect of Silicon Fertilizer

Si fertilizers are commonly used to increase the yields of Si-accumulating plants like rice and sugarcane since silicon shortage in soils is now understood to be a limiting factor in crop output [3].

Silicon Availability from Chemically Diverse Fertilizers and Secondary

These methods better reproduce the conditions of fertilizer dissolution in soil and around the root by (1) buffering the pH close to neutral and (2) extracting the dissolved Si (OH) 40 with ferrihydrite (Iron Bag method) for maximum quantitative extraction.

Silicon and plant nutrition—dynamics, mechanisms of transport and role

By addressing the drawbacks of chemical fertilizers, this review emphasizes an environmentally friendly alternative, namely, Si-solubilizing microorganisms (SSMs), as bioinoculants to liberate soluble Si and thus making it available to plants.

Effect of Silicon Fertilization on Crop Yield Quantity and Quality—A

Silicon (Si) is classified as a beneficial element. This element limits the effects of abiotic and biotic stresses in plants. The most known effect is the effect of silicon on plants, which uptake the largest amounts of this element, i.e., in sugar cane and rice.

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.

heavy metals contained in the fertilizers. Soluble potassium or sodium silicates are completely water soluble and can be used as foliar fertilizers, but are sually too expensive for soil application. Slow-releasing potassium-containing or potassium- rich silicates that are manufactured using feldspar as raw materials are not only cost-effective ...

Silicon fertilizer is an important agricultural fertilizer containing silicon elements, which play a crucial role in the growth and development of plants. some farmers have reported difficulties in dissolving silicon fertilizer during use. What could be the reasons for this?

First, it is essential to understand the composition of silicon fertilizer. Silicon fertilizer is typically made from silicate minerals such as quartz and feldspar. These minerals exist in a crystalline state in nature and are not easily decomposed by microorganisms in the soil. when silicon fertilizer comes into contact with soil, it does not dissolve immediately.

Secondly, the soil's pH level also affects the solubility of silicon fertilizer. Silicon fertilizer is harder to dissolve in acidic soils because silicate minerals tend to form precipitates under acidic conditions. In contrast, silicon fertilizer dissolves more easily in alkaline soils, as silicate minerals are more prone to hydrolysis under alkaline conditions.

Additionally, soil temperature and humidity influence the solubility of silicon fertilizer. High temperatures facilitate the dissolution of silicon fertilizer, while low temperatures make it more difficult to dissolve. Meanwhile, moist soil promotes the dissolution of silicon fertilizer, whereas dry soil hinders it.

To improve the solubility of silicon fertilizer, the following measures can be taken:

1. Adjust the soil's pH. By applying substances like lime or ammonium sulfate, the soil's pH can be lowered, making silicate minerals easier to dissolve.

2. Increase soil humidity. Irrigation or fertilization methods can be used to enhance soil moisture, thereby promoting the dissolution of silicon fertilizer.

3. Choose the appropriate type of silicon fertilizer. Different types of silicon fertilizers have varying solubilities; selecting one suitable for local soil conditions can enhance its solubility.

4. Use proper application methods. Evenly spreading silicon fertilizer on the soil surface followed by tillage helps increase contact between the fertilizer and soil, improving its solubility.

5. Pay attention to timing. Applying silicon fertilizer during the peak growth period of plants enables better absorption and utilization, thereby improving its solubility.

the difficulty in dissolving silicon fertilizer results from multiple factors, including its composition, soil pH, temperature, humidity, and application methods. To enhance the solubility of silicon fertilizer, corresponding measures such as adjusting soil pH, increasing humidity, selecting suitable fertilizer types, and using appropriate application methods should be adopted. Only by doing so can the full potential of silicon fertilizer in agricultural production be realized, promoting healthy plant growth and development.
