Medium-size soil particles are classified as which of the following?

Medium-size soil particles are classified as silt. Silt has a particle size that ranges between clay and sand; specifically, it consists of particles that are generally from 0.002 mm to 0.05 mm in diameter. This size classification is important for soil science because it affects the soil's properties, such as water retention, aeration, and nutrient availability.

Soils composed primarily of silt typically have good nutrient-holding capacity and can retain moisture more effectively than sandy soils, while still allowing for better drainage than clay soils. Understanding the classification of soil particles and their respective sizes is crucial for various applications including agriculture, conservation, and environmental management.
