Is sod grown in topsoil better than sod grown in peat?
Michigan State University reports there is no difference in rooting capabilities between mineral (topsoil) and muck (peat) sod initially or throughout time. Peat soil is much lighter than topsoil, which will make installation easier. Peat soil tends to promote more surface root growth which helps in the survival rate. Peat also tends to hold more moisture and nutrients which helps in sod transplanting survival.
