Loam is a highly desired soil type for gardening due to its unique blend of sand, silt, and clay that provides a healthy balance of air and water for plant growth. This type of soil is created by mixing together these components in equal parts, and it can also be achieved by adding soil amendments such as compost, peat moss, or sulfur to existing soil. Loamy soil is not defined by its acidity or alkalinity, but rather by its texture. It is composed of about 50% soil solids and 50% pore spaces and water, making it ideal for growing plants. Loam is often used interchangeably with the term "topsoil", but they are not the same. This type of soil is typically rich and friable, and has the potential to produce bumper crops in garden plots.
