Concept:Fertilizer labels use a ratio such as
10:0 to show the proportion of primary nutrients, namely nitrogen (
N), phosphorus (
P), and potassium (
K).
Explanation:The notation
10:0 indicates that the fertilizer contains nitrogen as the only major nutrient, with no phosphorus or potassium present.
In this ratio, the value
10 represents the nitrogen content, while
0 stands for the absence of the other nutrients.
Since nitrogen is the sole nutrient supplied, the fertilizer is specifically classified as a nitrogenous fertilizer.
Nitrogenous fertilizers are commonly used to promote leafy growth in crops.
Answer:B. nitrogenous fertilizer
