Front

What is soil texture?

Back

The relative proportion of different particle sizes in soil, including sand, silt, and clay.

Front

How does soil texture affect water retention?

Back

Soils with finer particles (like clay) retain more water than coarser soils (like sand).

Front

What is the role of humus in soil?

Back

Humus improves soil structure, increases nutrient retention, and enhances water-holding capacity.

Front

Back

Porosity is the measure of the void spaces in soil, indicating how much water it can hold.

Front

What is the difference between soil texture and soil structure?

Back

Soil texture refers to the size of soil particles, while soil structure refers to how those particles are arranged.
