“…The base saturation of the studied soils is rated as very high (> 80%) in Galana and Baringo and low (< 50%) in Yala and Bondo pedons. The high base saturation observed at the pedons can be attributed to higher CEC values which give the soils a greater capacity to retain bases [7]. When the soil pH is above 7.2, there is a free solution of Ca and Na unattached to the soil exchange complex that is unavoidably extracted.…”

“…Pedological characterization provides vital information and knowledge on soil characteristics and gives a clear understanding on soil genesis, morphology, classification and spatial distribution of soils in an area [3,1,4,5,6,7]. Soil characterization data helps in the correct classification of the soil to serve as a basis for a more detailed evaluation of the soil as well as gather preliminary information on nutrient, physical or other limitations needed to produce a capability class for crop production [8,2,4].…”

“…A soil profile representative of typical soils is dug to study its morphology, soil physico -chemical characteristics and hence classified [1,4,]. Therefore, it is important to carry out site-specific characterization to establish the prevailing heterogeneity of the soil pattern so that the required information may be generated for the potential of the soils and appropriate soil management practices [3,1,4,7].…”

Four soil profiles (Yala, Galana, Baringo and Bondo) that represent different ecology, physiography and pedological variability were described to study their morphology, soil physico-chemical characteristics and to classify them using two internationally known soil classification systems. Soil samples were taken from designated pedogenic horizons for physical and chemical analysis in the laboratory. These soils are deep to very deep (> 110 cm) and well-drained except in Galana which was imperfectly drained, with varying textures. In Bondo, the soils are moderately acid (pH 5.6 -6). In Baringo, the soil profile is acidic (< 5.0) while in Galana moderately alkaline (pH 7.3 -8.3) and Yala soils are moderate to strongly acid (5.1 -5.7). The organic carbon (< 0.6%) and organic matter levels (1 -2%) were low and decreased down the profiles in all. The soils have low to moderate fertility. The base saturation of the studied soils is rated as very high (> 80%) in Galana and Baringo and low (< 50%) in Yala and Bondo pedons. The soils are non-saline as indicated by the low values of electrical conductivity (< 1.7dS/m) in the pedons. The soils are non-sodic (ESP < 6%) in Bondo and Yala, however moderately sodic (ESP 11-15%) in Galana and Baringo. Ochric horizon was the main diagnostic epipedon while ferralic, argillic and cambic horizons were the diagnostic B horizons. According to USDA Soil Taxonomy, the soils were classified as Typic 2 Haplustox (Yala), Typic Haplocalcids (Galana), Typic Eutrudepts (Baringo) and Plinthic Haplustults (Bondo) corresponding to Haplic Ferralsols, Luvic Calcisols, Haplic Cambisol and Cutanic Plinthic Acrisols in the WRB for Soil Resources. The general fertility of the soils of the areas is discussed highlighting their potentials and constraints.

“…and Bulk Density (BD) Soil particle distribution is the relationship that shows different percentages of gravel, sand, silt and clay particles of certain soil [30]. Soil texture is one of the most stable and significant soil physical properties which have influence on other soil attributes including erodibility, water holding capacity, infiltration rate, nutrient retention, workability, soil consistence, soil aeration and fertility [35,6].…”

“…There was dominance of sand fraction in all horizons, where the content ranged from 56.24% in topsoil and decreased to 48.24% in the B horizon and thereafter increased dramatically to 82.24% in the C horizon. The coarseness of the texture suggests that the soil has low water retention, poor physical stability and generally low fertility [36,35].…”

This study was done in Morogoro and Mbeya regions of Tanzania to classify and characterize their respective soils.Representative pedons (SUARAT-P1 and UYOLE-P1) were dug and described using FAO guidelines clarifying morphological features, physico-chemical properties and genesis. The representative pedons were geo-referenced using Global Positioning System (GPS) receiver. A total of nine ( 9) genetic soil horizons were identified from both sites and samples from each horizon collected for physical and chemical analyses. Soils from both sites were very deep and topsoil moist colors ranged from hue of 7.5YR to 10YR with chroma of less than 3 in SUARAT-P1 and UYOLE-P1 pedons. Soil structure ranged from strong fine crumbs in topsoils to medium coarse sub-angular blocks in subsoils of SUARAT-P1 while UYOLE-P1 had weak fine sub-angular blocks in topsoils and subsoils. The SUARAT-P1 had sandy clay (SC) texture in topsoil and clay texture in subsoil while UYOLE-P1 had sandy loam (SL) in topsoil and sand clay loam (SCL) in subsoil. Soil reaction were slightly acid to very strongly acid in SUARAT-P1 (pH 6.54 -4.46) whereas UYOLE-P1 were slightly acid to neutral in subsoil horizons (pH 6.35 -7.32). Organic carbon ranged from very low to low (0.12-0.95%) in SUARAT-P1 and from very low to medium (0.47 -1.5%) in UYOLE-P1. Nitrogen levels were very low to low (0.05 -0.12%) in both sites whereas available P ranged from low (0.30 mg kg -1 ) to medium (8.55 mg kg -1 ) in both pedons. CEC of SUARAT-P1 was medium ranging from 12.4 to 23.2 cmol(c) kg -1 , whereas UYOLE-P1 was medium to high (15 -34 cmol(c) kg -1 ). In SUARAT-P1, topsoil BS was high (> 50%) and low (< 50%) in the subsoil while UYOLE-P1 registered high BS throughout its profile depth. As diagnostic horizons for soil classification, the SUARAT-P1 had an ochric epipedon overlying a kandic horizon and classified according to USDA Soil Taxonomy as Typic Kandiustults, while UYOLE-P1 had an ochric epipedon over a cambic horizon and was named as Andic Dystrudepts corresponding respectively to Haplic Lixisols and Eutric Andic Cambisols in the WRB for Soil Resources. The results have indicated that, studied soils are less fertile with possible reconstitution through land and crop managements which include but not limited to no-tilling or conservation tillage, manuring and proper fertilizer application; residue retention, possible fallowing, liming for potential buffering of soil pH especially at SUARAT-P1 and crop rotation and intercropping with leguminous crops.

Groundwater is a vital natural resource for agricultural, domestic and industrial uses. Understanding the spatial distribution of groundwater resources is critical to improving the relationship between water, food and energy. This article uses GIS and remote sensing and the analytical hierarchy process (AHP) technique to map the potential groundwater zones in the Lupane district. Lineaments, drainage density, slope, soil type, geology and land use land cover (LULC) were used to create thematic maps in ArcMap. The thematic maps were weighted and ranked according to their influence on the movement and occurrence of groundwater. To validate the groundwater potential zones (GWPZs) model, we used LULC and 675 perennial and seasonal boreholes in the Lupane district. The LULC and borehole maps were overlaid on the modelled GWPZ map to highlight their distribution. The GWPZ results show that areas with good potential make up the majority of the district (41%), followed by areas with moderate potential (30%), poor potential (14%), very good potential (13%) and very poor potential (2%). The results showed that 74% (499) of perennial boreholes overlapped the zones with good, moderate and/or very good groundwater potential. The GWPZ map can therefore be used as a preliminary reference when selecting suitable sites for the exploitation of groundwater resources. Further testing of the model using both seasonal and year‐round yields and depths from boreholes is recommended.
