What is the texture of soil that has equal amounts of sand, silt, and clay particles? 

Loam is the texture of soil that has equal amounts of sand, silt, and clay particles.

Loam soil is a type of soil that contains roughly equal proportions of sand, silt, and clay particles. Loam soil has a crumbly texture that feels light and airy in the hand, with a mixture of coarse and fine particles that provide good drainage and water-holding capacity.

Loam soil is considered the ideal soil type for plant growth because of its balance of physical and chemical properties. It has good water-holding capacity, which helps plants access water during dry periods, but also drains well to prevent waterlogging. The balance of coarse and fine particles allows air to circulate through the soil, providing oxygen to plant roots, while also retaining nutrients in the soil for plant uptake.

Loam soil is also easy to work with and is often used for gardening and farming purposes. It can be easily amended with organic matter to improve soil fertility and structure.
