Casa De Amor NPK 19 19 19 Fertilizer for Plants and Gardening All Purpose Plant Food

NPK fertilizer is a complex fertilizer comprised primarily of the three primary nutrients required for healthy plant growth. The agriculture industry relies heavily on the use of NPK fertilizer to meet the global food supply and ensure healthy crops. Nitrogen Nitrogen is an essential nutrient for numerous plant functions and is one of the elemental components of chlorophyll. Nitrogen fuels vegetative growth, particularly the foliage, stems and branches. Plants can deplete the soil of nitrogen, leaching from the soil faster than any other element. If your plants have yellowing leaves or appear stunted with poor growth, the soil may lack nitrogen. By using a soil test kit, you can determine which element may be missing in your soil. Phosphorus A stimulant for root growth, seed and flower formation, phosphorus is most available to plants when the soil pH is between 5.5 and 7. The pH refers to the acid or alkaline level of the soil and can range from 0 to 15 with 7 regarded as neutral.
