Fertilizers are identified by the fertilizer grade on the bag. The 3-number grade tells you about the percentages of the nutrients available in the fertilizer. If you picked up a bag of 15-30-10 fertlizer, it would have which of the following combinations of nutrients? Select one: a. 15% potash (potassium), 30% sulfur, 10% nitrogen b. 15% nitrogen, 30% phosphorous, 10% potash (potassium) c. 15% nitrogen, 30% potash (potassium), 10% phosphorous d. 15% phosphorous, 30% sulfur, 10% nitrogen

GeoPanther

Answer:

b. 15% nitrogen, 30% phosphorus, 10% potash (potassium)

Explanation:

The marks on the packages of the fertilizers are telling us what is their content. The system used id the N-P-K ratio. The N-P-K ratio is giving us information about the chemicals from which the fertilizer is made, and the percentage of each of them. N stands for nitrogen, P stands for phosphorus, and K stands for potash (potassium). In this case we have 15-30-10. This will mean that the percentage of nitrogen is 15%, the percentage of phosphorus is 30%, and the percentage of potash (potassium) is 10%, meaning that we have a fertilizer that is high on phosphorus content.
