Title

CONSIDERATION OF SOLUTE AND MOISTURE CHANGE IN PISTACHIO ROOT ZONE BY LEACHM MODEL

Pages

  26-36

Abstract

 The simulation models of solute and water flux is suitable method for prediction of SALINITY and moisture variation in soil profile. One of solute water movement model is LEACHM. This model simulates one-dimentional solute, water and chemical reaction and root water uptake in unsaturation zone An experiment was counducted in order to consideration of solute and moisture of ROOT ZONE in PISTACHIO orchards in north of ardakan in central of Iran (32o 27 N, 53o 54 E) and LEACHM model was assessed for PISTACHIO orchards. The capablility of this model for 30 cm depth in growth season was successfully but increased until end of season. For 60, 90 and 120 cm depth prediction was the same. In 30 cm depth the soil SALINITY was increased affected by the capillary rise. The prediction of LEACHM model show that soil moisture was decreased more than observed values and after several days change of moisture decreased greatly. In all of depths the soil moisture has smooth changes and this change continues until the next irrigation. It was the common points of all depths that predictions were lower than observed values. In 90- 120 cm depth moisture front moved late thus increasing of moisture had delay. In nongrowing season, the SALINITY decreased in soil profile because of leaching fraction and showed that salt distribution in ROOT ZONE is steady state.
