| Description: |
Theobjectives of this study were to classify the soils of Tembaro district, and toidentify its potentials for crop production. Five pits representing a pedon each were opened and profile in each pitwas described for its morphological, physical and chemical characteristicsaccording to standard procedures. A total of 20 disturbed soil samples and 16core ring samples were collected from five representative profiles. The sampleswere analyzed in the laboratory for texture, BD, FC, PWP, Soil pH, EC, OC, TN,av.P, av.K, exchangeable bases, free and active iron and CEC. The resultsshowed that the proportions of soil separates varied among profile and depthhowever, soils were all in clay textural class. The BD varied from 1.02 in thesurface profile 1 to 1.25 g.cm-3 in the profile 3. Soil pH rangedfrom 6.8 to 5.4 in the surface horizons of all profiles with further decreasewith depth indicating that the soils in the watershed are slightly acidic tomoderately acidic. The OM and TNcontents ranged from 2.90 to 5.43 and 0.23 to 0.45% in the surface horizon andthey were in the low, low to medium and high categories respectively. Thecorresponding values for the remaining subsoil horizons were in the lowcategories. In all cases the contents of these parameters decreasedconsiderably with depths. Available P was below critical values for allprofiles and depths except for profiles 1 and 4. Exchangeable K was abovecritical value in all profiles with increasing trend along with depth of allprofiles. Exchangeable Mg varied from2.47 in surface horizon of profile 3 to 3.98 cmolc kg-1 in thesurface horizons of profile 4 and increased with depth in all profiles exceptin profile 1. The observation with exchangeable K and Mg implies that there isleaching phenomenon in the study area. Ca ranged from 4. 35 cmolc kg -1in profile 5 to 16.50 cmolc kg -1 in profile 1 with inconsistenttrend with depth. The CEC from 18.22 cmolc kg -1 soil in surfacehorizon of profile 5 to 27.43 cmolc kg-1soil in the surface horizons of profile1 indicating they are ... |
