After reading this article you will learn about the physical, mineralogical and chemical nature of soil separates. Physical Nature of Soil Separates: Soil separates consist of stones, gravels, sands, silts and clays. Their nature is described briefly. (i) Stone, Gravel and Sands (Coarse Fragments): Stones and gravels range in size from 2 mm upward and may be almost rounded, irregularly [...]
After reading this article you will learn about the relationship between porosity and density of soil. % soil space = bulk density/particle density Since, % pore space + % soil space = 100 or % pore space 100 - % solid space or % pore space = 100 – bulk density/particle density × 100 % pore space = 100 (1 [...]
After reading this article you will learn about:- 1. Meaning of Porosity of Soil 2. Types of Pores in Soil 3. Factors Affecting Porosity of Soil. Meaning of Porosity of Soil: Pore-spaces (also called voids) in a soil consist of that portion of the soil volume not occupied by solids, either mineral or organic. The pore-space under field conditions, are [...]
