Abstract
The objectives of this work was study iron status and factors affecting its availabliity in representative soils collected from the saltanat of oman . An incubation experiment was conducted to study the effect of CaC03 content , addition of 2.5% organic matter, forms of Fe applications as Fe So4- 7 HzO or Fe- EDDHA (20 ppm), 80 ppm of sulphur and the time of incubation on the availability of Fe and other chemical properties of collected two soils (Soil No.I had coarse texure and highly calcareous, Soil No.2 had sandy loam and relatively low CaC03 content). Also, a greenhouse experiment was carried out to study the effect of CaC03 , addition of 2% organic
matter , and 20 ppm of Fe as Fe- EDDHA to the soil or 30 ppm of
Fe as Fe- EDDHA foliar application on the availability of N, P, K, Fe, Mn and Zn in soil and plants, dry weight, contents and uptake of these elements by com plants grown under different treatments . A factorial experiment design was used in the two experiments . The data were analyzed statistically by analysis of variance and by multiple range test .
