Abstract A study was conducted to evaluate the effect fertility to iron in soils from 20 sites Euphrates in the growing season ( 2012-2013 ) . The study included tow experiments the first laboratory to assess the efficiency of the four ways to extract iron and ready-to- plant and two biological experience of the first to identify the critical limit for iron soil ready. Has been added to iron metal FeSO4.7H2O (20% Fe) are two levels (5,0 ) mg . Kg -1 soil and plant wheat planting class ( Tamouz-2 ) as evidence . Use randomized complete block design RCBD averages were compared by LSD test and the level of probability of 0.05 results of the study can be summarized as follows : Extraction of iron 1 . The efficient methods of extracting iron soil can be arranged as follows : - HCl Keywords | ||
