Why is clay soil more porous than sand? – KnowledgeBurrow.com

WebPorosity depends on both soil texture and structure. For example, a fine soil has smaller but more numerous pores than a coarse soil. A coarse soil has bigger particles than a fine soil, but it has less porosity, or overall pore space. Water can be held tighter in small pores than in large ones, so fine soils can hold more water than coarse soils. WebCorrect option is C) Explanation: Clay can have a very high porosity.
