OSA 28 Silicic Acid / Orthosilicic Acid by Plant Science Concepts

osa28_logo_1

Silicic acid such as OSA 28 is very important for optimal plant health. Countless studies over the last couple decades from around the world show how silicic acid helps growers build stronger plants, optimize crop nutrition, plus increase yields and quality. OSA/28 Stabilized orthosilicic acid is a small group of silicic acid molecules suspended in solution. When added to water, these molecules break apart into monomer form — this is how silicon becomes immediately and rapidly available to plants! Faster Growth Under fast growth conditions like indoor gardening, plants need constant resupply of essential elements. Every second nutrients are unavailable slows growth. Silicic acid works in many ways listed here to increase the transport and utilization of minerals, proteins and transports systems to ramp up growth. Tighter Node Spacing Countless studies show silicic acid affecting plant structure. It’s one of the most visible and quickest effects growers report. Silicic acid builds more rigid and compact cells. It also helps convert more nitrates into proteins, which impacts node spacing and increases flowering sites. Increased Nutrition As silicon accumulates in cell walls, it concentrates and hardens. The nutrient transport system (xylem/phloem) is strengthened and expanded, increasing sap pressure and making heavier nutrients like calcium move better through the plant. More nutrients mean more essential building blocks. Greater Yields All plants accumulate silicon to some degree. Rice for example, up to 10% of dry weight! Flowering plants like tomatoes closer to 2-3%. Since silicon is twice as heavy as nitrogen and almost 3x carbon, a small amount of silicon contributes to large gains in yield. Stress Resistance Silicic acid is shown to establish powerful stress resistance factors when plants face tough conditions. It also helps with osmoregulation (water usage), making the plant more resistant to stresses like drought, heat, cold, and other environmental stresses
