What elements make up the fertilizer ratio?

The correct answer highlights the primary macronutrients that are essential for plant growth, which are Nitrogen, Phosphorous, and Potassium. These elements are commonly referred to as N-P-K and are fundamental components of fertilizers used in agriculture and landscaping.

• Nitrogen promotes healthy leaf and stem growth, playing a crucial role in the development of green foliage. It is vital for the synthesis of amino acids, which are the building blocks of proteins needed by plants.

• Phosphorous is key for root development and flowering. It assists in the formation of DNA and RNA, which are essential for cell division and growth. Phosphorous also helps in energy transfer within the plant, particularly through ATP (adenosine triphosphate).

• Potassium is important for overall plant health. It helps regulate various physiological processes, including water uptake, enzyme activation, and resistance to diseases. Potassium also contributes to the quality of fruits and flowers.

These three nutrients work together to ensure that plants can grow robustly and produce effectively, which is why they are the primary components in the fertilizer ratio. Understanding this ratio helps public works managers and other professionals in selecting the right type of fertilizer to enhance plant health in public spaces and
