Soil Texture
Texture refers to the size and distribution of the soil particles and is most influenced by the mineral content. The texture can tell you a lot about a soil: fine textures, common with clay soils, get compacted easily, and compacted soils don’t let much air and water in. Coarse textures, common with sandy soils, let plenty of air and water in but don’t hold them well.
The ideal garden soil is the one that best suits the needs of your plants. Although some plants prefer more extreme soil conditions, the best soil for most plants will be one that has a loamy texture, good granular structure, and plenty of organic matter.
