Understanding NPK Fertilizers High in Nitrogen

NPK fertilizers are categorized by their nitrogen (N), phosphorus (P), and potassium (K) content, and those high in nitrogen typically have a ratio that emphasizes the first number. For example, a fertilizer with a ratio of 30-10-10 is high in nitrogen. This essential nutrient is responsible for photosynthesis and plant growth, making it a primary choice for leafy greens and annuals.
