Flashcards
Total Nitrogen (N)
Total Nitrogen (N)
Total Nitrogen (N) is a key nutrient for plant growth. It helps in the production of chlorophyll, which is essential for photosynthesis. The minimum specified limit for total nitrogen in this nano urea sample is 16%. This means that the sample should contain at least 16% nitrogen by weight.
Total Phosphorus (P2O5)
Total Phosphorus (P2O5)
Total Phosphorus (P2O5) is another essential nutrient for plant growth. It plays a vital role in root development, flower bud formation, and seed production. The specified limit for total phosphorus in this sample is between 4.8% and 8.5%. This means the sample must have at least 4.8% and no more than 8.5% phosphorus by weight.
pH
pH
pH is a measure of the acidity or alkalinity of a solution. It ranges from 0 to 14, with 7 being neutral. The specified limit for pH of the nano urea sample is between 3 and 7, indicating it should be slightly acidic to neutral. This pH range is considered optimal for the stability and effectiveness of nanoparticle fertilizers.
