Loamy soil has an almost equal amount of silt, clay, and sand. Presence of an equal amount of soil particles of various size imparts enough pores to loamy soil to facilitate water drainage. Space between these soil particles help the plant roots to breath properly as ample of oxygen is present in spaces. Loamy soil does not allow the nutrients to run off as its clay component trap the nutrients.

hence, loamy soil has properties of sand, clay, and silt to support the plant growth which makes it ideal  for gardening.
