Journal Article
Development soil fertility map by geographic information system technology for al-Souera
2019
Overview
The study area is located in Wasit province, represented in Al-Souera about 60km south of Baghdad (464273.369- 463318.982) East and (3643443.734 - 3643798.3013) North. GIS technology was used to predict some of soil fertility parameters by using Kriging Application and to produce a final fertility map by standard method of assessment, building a database of soil characteristics in GIS environmental. The results showed: There were four classes of fertility assessment in the study area, very fertile soil class was not found because the study area did not contain the ideal state of the indicators used in soil fertility assessment. The fertile soil class in the study area was 7.53% from the total area were silty clay loam texture, high organic matter, neutral pH, moderately CaCO3, high CEC, high contain NPK, low ECe , and low ESP. The moderately fertile soil class in the study area was 51.99 % from the total area were silty clay loam texture, low organic matter, neutral pH, high CaCO3, high CEC, high contain NPK, low ECe, and low ESP. The slightly fertile soil class in the study area was 39.61 % from the total area were silty clay loam texture, moderately organic matter, neutral pH, high CaCO3, high CEC, high contain NPK, moderately ECe, and low ESP. The non-fertile soil class in the study area was 0.93% from study area. The soil productivity digresses because of low organic matter, high CaCO3, and high ECe.
