Several benefits of silicon to plants are now recognized. GMPro Magazine (12):33-35. Most terrestrial plants grow in media dominated by silicates, and the soil solution bathing roots contains Si at concentrations exceeding those of phosphorus (P) by roughly a factor of 100. The percentage of silicon that accumulates in the tissue is also listed under each plant category. OFA Bulletin. Cavins, T., S. Marek, and S. Kamenidou, 2010 "Silicon enhances disease suppression." Adding silicon to the fertilizer program in poinsettias production: benefits and facts. Among others, those include nitrogen, phosphorus and potassium. Water sources typically provide silicon as well as the growing medium components and even dust contains useable silicon. Silicon seems to benefit certain plants when they are under stress. To err on the side of caution, it is best to have separate stock tanks for a silicon fertilizer and your standard fertilizer. Locke, J. In the case of powdery mildew and phytophthora, disease attack was delayed in silicon treated zinnia, rose, sunflower, cucumber (all powdery mildew) and gerbera (phytophthora), but after 1-3 weeks both silicon treated and untreated plants had the same amount of disease. This article will help you better understand the role of sulfur in your plant culture. Since silicon is not considered an essential element, most plants will grow normally without it. It will also cover endeavours including functional evaluation of transporters involved in Si uptake and transport in plant species through transgenic approaches, genomic approaches and transcriptome profiling, protein structure prediction, and mutagenesis. Important Note: Landscaping In the above table, plants are categorized based on their tendency to accumulate silicon. Do not exceed 200 ppm as it may cause phytotoxicity in some non-accumulators as was seen in gerbera and sunflower. Also, silicon has been found to help increase stem strength. The research does show benefits of using silicon with certain agricultural crops (rice, wheat, sugarcane, etc. White, J. D.  2007. Do your plants have a deficiency or a toxicity related to magnesium? As stated above, crop inputs such as water, fertilizer and growing medium may supply sufficient silicon for non-accumulators and perhaps intermediate accumulators. April 2007:34. For example, tomato, which is a non-accumulator, had increased flowering and fruit set when given additional silicon. Silicon (Si) is the second most abundant element in the earth crust after oxygen. The soil water, or the "soil solution," contains silicon, mainly as silicic acid, H4SiO4, at 0.1-0.6 mM--concentrations on the order of those of potassium, calcium, and other major plant nutrients, and well in excess of those of phosphate. While research shows some benefits of using silicon on agricultural crops, such as rice and sugarcane, silicon and gardening generally don’t go hand in hand.In other words, the home gardener does not need to use silicon, especially until further research has been established. Silicon is the second most abundant element in soils, the mineral substrate for most of the world's plant life. Silicon (Si) is one of the most prevalent macroelements, performing an essential function in healing plants in response to environmental stresses. This article will help you better understand the role of sodium and chloride in your plant culture. Silicon is an essential element for plants. However a few plants have shown deleterious effects if silicon is withheld. GMPro Magazine (8):58. Elemental silicon (Si), after oxygen, is the second most abundant element in the earth’s crust, which is mainly composed of silicates. Background: Silicon (Si) is known to have numerous beneficial effects on plants, alleviating diverse forms of abiotic and biotic stress. Leatherwood, R. and N. Mattson. Frantz, J.M., J.C. Locke and N. Like other fertilizer elements, silicon needs to be supplied throughout the crop cycle. aluminum, copper, iron, manganese, zinc, etc.). total views This article will help you better control this micronutrient. In gerbera and sunflower, high levels of silicon were found to deform flowers. This article will help you better control this micronutrient. 2007.
