Detailed explanation-1: -Loamy soil is ideal for most garden plants because it holds plenty of moisture but also drains well so that sufficient air can reach the roots. Many gardeners complain of their garden soil being compacted and/or poorly drained. Heavy, compacted soil can be rescued by the enduring gardener.

Detailed explanation-2: -Loamy soil is best for plant growth as it has high water retention capacity thus it retains water for long and also retains the nutrients which is required for plant growth.

Detailed explanation-3: -The ideal mixture for plant growth is called a loam and has roughly 40% sand, 40% silt and 20% clay. Another important element of soil is its structure, or how the particles are held together-how they clump together into crumbs or clods. A loose structure provides lot of pore spaces for good drainage and root growth.

Detailed explanation-4: -Most common garden plants prefer loam-soils with a balance of different-sized mineral particles (approximately 40% sand, 40% silt, and 20% clay) with ample organic matter and pore space. However, some plants grow better in sandy soils, while others are well-adapted to clay soils.
