Diatomaceous Earth: Diatomaceous earth, also known as diatomite and DE, is the naturally occurring fossilized remains of diatoms-single-celled aquatic algae.While typically a combination of silicon dioxide and metal oxides, sometimes it contains metal sulfides and other metals depending on the refining process that can be toxic to your plants. Slag: Slag is a by-product from the industrial processing of iron and other alloys and can be used as a source of plant available silica.The majority of this silicon is bonded with oxygen and other elements in the crystalline fabric of mineral soil. Standard soil: The total elemental analysis of typical mineral soil is about 28% silicon and 47% oxygen.Some sources of plant available silica include: For this reason, it’s important to look at the right fertilizer and substance ingredients for plant health while keeping an eye on secondary effects such as irrigation, plant disease, and aeration. There isn’t a single way to determine the best soil mix for plant health and crop production. For example, sand, pumice, perlite, vermiculite, and rockwool are technically silicon materials, but the silicon is hardly available to plants and they won’t offer health benefits. One of the most important things to know when choosing your silica source is that not all products containing silicon provide plant-available silica. Sources of Silicon-rich minerals are abundantly available, yet researchers have found it’s the type of silicon that is converted into the plant available form that counts most. It is known to improve structural integrity to help combat abiotic and biotic plant stressors including: Plant Available Silica (PAS) is translocated to the plant’s cell wall through the roots of a plant. Today, we’re reviewing the importance of plant-available silica and how diatomaceous earth plays a role in the success of your growing. The organization identified that it’s important for growers to focus not on products with high SiO2 content, but that plant available or soluble silicon content is key. Recently, AAPFCO acknowledged silicon dioxide as a Beneficial Substance and subsequently published an approved method for testing soluble silicon. Previously, silicon dioxide was known by growers as an important part of soil or soilless media mixes to help plants grow healthier, but it was not recognized by the Association of American Plant Food Control Officials (AAPFCO) as an important substance.
