Abstract

For making decisions on agricultural production and other land use types, understanding the types and characteristics of soils is essential. This study was conducted with the aim of characterization and classification of soils of Leka Dullecha district and produces a map of these soils. Based on slope, geology, land form, soil depth, color, texture, and structure, soil mapping units were categorized (USDA soil textural classes). Understanding the relationships and interactions between the various soil qualities was made easier by the separation of the study site into SMUs. Cambisols, Acrisols, Nitisols, Lixisols, Vertisols, Fluvisols, and Leptosols were the seven main soil types discovered at the study location. The pH ranged from 4.0 (highly acidic) to 6.3 (moderately acidic), with a value of 4.9 as the average. Mean total nitrogen was found to be 0.06% (low) and 0.41% (high) in the SMU3 and SMU10, respectively with the mean values of 0.24. Soils of all SMUs had a fairly medium to high exchangeable Ca and Mg content. The CEC of the soils ranged from 1.08 to 27.94cmolc kg-1 with a mean value of 15.9. OC was positively and significantly correlated with TN (r2 = 0.999) at p < 0.001. Besides, CEC was significantly and negatively correlated with EA (r2 = -0.397) at p < 0.05. The concept of soil–landscape relationships helps to categorize highly variable soils into relatively distinct management zones. Therefore, soil classification was developed to aid in land management.
