Amending Sandy Soil: What Is Sand Soil And How To Improve

Sand is primarily small pieces of eroded rocks. Sand tends to have large particles and the particles are solid and have no pockets where water and nutrients can hold to it. Because of this, water and nutrients tend to run out, and because sandy soil lacks
