Abstract: 

Abbandansar peat from a natural water tank, 5 kilometers southwest of Sari city (the Mazandaran province) was used in this research. Four rates of peat (0, 25, 50 and 75 percentage volume) were mixed with a sandy clay loam soil and a sand soil and their effect and also the effect of mere peat (100 percent) on evaporation, temperature and mechanical resistance. Dry bulk density and water holding capacity at different pressure steps (0,0.1 and 15 bars) were also measured and compared statistically. Incorporating peat increased soil and sand water content at 0, 0.1 and 15 bars and also available water. Soil and sand temperatures were slightly increased and mechanical resistance decreased. Evaporation rates were increased for sand cultures and decreased for soil. The magnificent effect of this peat on improving mineral soil available water is ideal for mixtures used in specific plant growth media and nursery.
