Understanding the Nitrogen Contribution of NH4NO3 in Soil Fertilization

Introduction to Fertilizers and Soil Nitrogen

Soil fertility is essential for plant growth and crop production. One of the primary nutrients plants require is nitrogen, which is often supplied through fertilizers. NH4NO3 (ammonium nitrate) is a common nitrogen fertilizer used in agriculture because of its high nitrogen concentration and ease of application. This article will explore how to calculate the amount of nitrogen added to the soil when 48.5 grams of NH4NO3 is applied.

How Much Nitrogen Will Be Added to the Soil?

Let's break down the calculation for the amount of nitrogen added to the soil when 48.5 grams of NH4NO3 is applied. First, we convert grams to moles, then use the molar ratio, and finally convert moles back to grams. Here are the steps:

Convert grams of NH4NO3 to moles:

48.5 g NH4NO3 × (1 mol NH4NO3 / 80.043 g) 0.6059 mol NH4NO3

Use the molar ratio to convert moles of NH4NO3 to moles of N:

0.6059 mol NH4NO3 × (2 mol N / 1 mol NH4NO3) 1.2118 mol N

Convert moles of N to grams:

1.2118 mol N × (14 g N / 1 mol N) 16.9652 g N

Therefore, 16.966 grams of nitrogen will be added to the soil when 48.5 grams of NH4NO3 is applied.

Conclusion

Understanding how to calculate the nitrogen contribution from NH4NO3 can help farmers optimize their nutrient management strategies. By knowing how much nitrogen is added to the soil, you can make more precise applications, which can lead to better crop yields and more sustainable practices.
