The average annual rainfall in Dubuque lowa is 36 inches. If the rainfall contains 0.5 ppm of nitrogen, how much nitrogen is added to the soil in Dubuque in an average year?

total amount of nitrogen added to soil per square meter is 457.2 mg

Explanation:

given data

average rainfall = 36 inches = 914.4 mm

in 1 mm rainfall total amount of water stored in squre mtr = 1 liter

therefore in 914.4 mm rainfall, total water stored = 914.4 ltr

rainfall consist of 0.5 ppm = 0.5 mg/ltr

1 ltr consist N2 = 0.5 mg

914.4 ltr consist N2 = 0.5 * 914.4 mg = 457.2 mg

total amount of nitrogen added to soil per square meter is 457.2 mg
