Evaluation of the Readiness of NPK Elements for the Soils of the Mouradia Agricultural Project in Babil Governorate

Abstract

The current study included the selection of three agricultural fields from the soil of the Muradia Agricultural Project of the Directorate of Agriculture in Babil Governorate. Thirty-four samples were taken from them at a surface depth of 0-30 cm, in order to evaluate the readiness of NPK elements through the soils of various fields with agricultural use. As the size distribution of the soil classes was mostly dominated by silt, and thus the type of tissue ranged from a silty clay mixture to a silty mixture. The soil interaction values ranged between 7.0-7.90, and the electrical conductivity ranged between 1.31-6.23 ds m-1 in all study soils, except for the unexploited comparison soil samples in which the soil interaction values were between 7.36-8.30, and the electrical conductivity ranged between 8.39-24.36 ds m-1. The soil content of organic matter was 10.30-20.00 and 3.40-9.60 mg kg-1, respectively. The values of the exchange capacity of the positive ions varied in the soils of the current study, as they ranged between 9.09-14.9 cmol charge kg-1, and its height in other soils ranged between 16.5-25.91 cmol charge kg-1. The values of available nitrogen ranged between 23.00-48.18 mg kg-1 in all the study soils, except for the unexploited control soil samples in which it was 22.15-30.16 mg kg-1, while phosphorus ranged between -17.54-31.20 and 8.20-17.20 mg kg-1, respectively., while potassium ranged between 175.11-205.16 and 149.30-165.22 mg kg-1, respectively.
