Soil is a complex living system made up of minerals, organic materials, water and air. Physical properties such as soil texture (soil particle size) and soil structure (how particles are held together) determine air and water movement, which in turn affects plant growth. Most soils in Iowa are well suited for vegetables, flowers and turf though a few may have special problems you can correct before planting. See the ISU Extension & Outreach Yard & Garden news release from March 14, 2012 for answers to common questions about corrective actions you may have considered.
