### Question

What is the percentage water content of soil sample which weighed 180g when fresh and 120g when oven-dried?

A)
20.14%
B)
25.00%
C)
33.33%
D)
60.00%

### Explanation:

This question is asking for the percentage water content of a soil sample. The soil sample originally weighed 180g when it was fresh, but it reduced to 120g when it was dried in an oven.

To find the percentage water content, we need to calculate the difference between the fresh weight and the oven-dried weight of the soil sample. In this case, the difference is 180g - 120g = 60g.

Next, we divide the difference by the fresh weight and multiply by 100 to get the percentage. So, (60g / 180g) * 100 = 33.33%.

Therefore, the correct answer is Option C: 33.33%, which represents the percentage water content of the soil sample.

Understanding the water content of soil is important in agriculture because it helps us determine the amount of water available for plants. Water content affects the soil's ability to support plant growth and determines the need for irrigation or drainage. By measuring the water content, farmers can make informed decisions about watering their crops and managing soil fertility.

It's also worth noting that the water content of soil can vary depending on factors such as soil type, climate, and agricultural practices. Different crops have different water requirements, so it's essential to monitor and manage soil water content to optimize crop growth and yield.
