The active ingredient in fertilizers refers to the primary nutrients that can be absorbed by plants, and it is typically expressed as a percentage of the element's weight. For example, nitrogen content is denoted as %N, phosphorus as %Pâ‚‚Oâ‚… (phosphorus pentoxide), and potassium as %Kâ‚‚O (potassium oxide). These percentages indicate the concentration of the main nutrients available for plant uptake.
In addition to these primary nutrients, fertilizers may contain other components, known as secondary or accessory ingredients. For instance, ammonium sulfate contains about 20% to 21% nitrogen, which is the active ingredient, while the sulfate portion is considered an accessory component. Similarly, in superphosphate, the active ingredient is calcium dihydrogen phosphate, Ca(H₂PO₄)₂·H₂O, along with a small amount of free phosphoric acid. The accompanying component in this case is anhydrous calcium sulfate.
Understanding the difference between active and accessory ingredients is essential for determining the effectiveness and suitability of a fertilizer for specific crops and soil conditions. Fertilizer labels often list these components to help farmers make informed decisions about nutrient application. Proper use of fertilizers not only improves crop yield but also helps maintain soil health and environmental sustainability. Always follow recommended application rates and guidelines to avoid over-fertilization, which can lead to nutrient runoff and pollution.
LED Street Light Module
An LED street light module is a lighting device that utilizes light-emitting diodes (LEDs) to produce illumination for outdoor street lighting applications. It typically consists of a group of high-power LEDs mounted on a circuit board, along with a heat sink and a lens or reflector to direct the light output. LED street light modules are known for their energy efficiency, long lifespan, and superior brightness compared to traditional street lights. They are also highly customizable, allowing for different color temperatures, beam angles, and dimming options. LED street light modules are commonly used in urban areas to provide safe and efficient lighting for pedestrians and motorists.
