Which of the following is NOT one of the four properties of soil?

The four properties of soil typically include texture and structure, organic matter, moisture, and pH. Each of these properties directly relates to the physical and chemical characteristics of the soil itself.

Texture and structure pertain to the size of soil particles and how they are arranged, affecting water retention and nutrient availability. Organic matter relates to the decomposed plant and animal material in the soil, which is crucial for soil fertility and health. Groundwater depth is a factor that can influence soil moisture levels, but it is not an inherent property of the soil itself.

Climate conditions, while they have a significant impact on soil formation and health over time, are external factors. They do not describe a property of the soil but rather the environmental context in which the soil exists. Therefore, climate conditions do not qualify as one of the fundamental properties of soil. This distinction is important for understanding soil management and agriculture practices effectively.
