True or False? To determine the nutrient content of a liquid fertilizer, you need to know the weight per gallon of the fertilizer.

To determine the nutrient content of a liquid fertilizer, knowing the weight per gallon of the fertilizer is essential. This is because liquid fertilizers are often expressed in terms of weight per unit volume, which directly influences the concentration of nutrients present.

For example, the nutrient values on the label are typically based on a specific volume, and different fertilizers can have varying densities. By understanding the weight per gallon, you can calculate how much of each nutrient is available in a certain volume of fertilizer. This information is crucial for applying the correct amount of fertilizer to meet plant needs without risking environmental harm or nutrient runoff.

Thus, the statement that you need to know the weight per gallon to accurately assess the nutrient content of a liquid fertilizer is true.
