“…Most of the soils studied in the Sahel savannah were comparable in Ca and K contents (10.4 cmol kg -1 and 0.4 cmol kg -1 respectively) with very productive Asian lowland rice soils as cited by Abe et al (2010), but were lower in organic carbon. This might explain why the Far North Region of Cameroon (Sahel savannah) accounts for twothirds of national rice production figures.…”

“…Inland valleys and flood plains are diverse in characteristics and potentials and require different management interventions to guide land use intensification. Abe et al (2010) provides an evaluation of soil fertility potential of lowland rice soils in West Africa, relative to soils in Asia, which has been used to inform policy on rice production at the regional scale. The same kind of information is needed at national scales to inform decision-making on rice production.…”

Fertility capability classification (FCC) system is a technical soil classification system focusing quantitatively on physical and chemical properties of soil important to soil fertility management. Lowland rice cultivation is a major activity in Cameroon, where demand for the commodity is increasing amidst increasing production constraints. This study was intended to classify lowland rice soils in major rice-growing areas into fertility capability classes, identify soil fertility limitations to increased lowland rice cultivation, and identify research areas needed to boost and sustain rice yields. Secondary data of selected soils characterized for morphological, physical and chemical properties was used. Soil fertility limitations characterizing lowland rice producing areas in Cameroon were: Fe-and Al-toxicities (a), low nutrient capital reserves (k), high leaching potential (e), and micronutrient deficiencies (Fe and Zn). The lowland soils were classified as: Lagk, Cagk, Laegk, Cbgm, Caeg, Lbg, Lgk, Cgv, LCg and Cgv, which reflect these limitations. A high potential exists to increase national rice production in Cameroon through research aimed at reducing the effects of Al and Fe toxicity, increasing nutrient capital reserves based on appropriate cultural and chemical techniques.

“…On average all the units in the MIS showed deficiency in soil Zn concentration (< 2.0 mg/kg). Such high incidences of Zn deficiency stress have also been reported on Ethiopian Vertisols (Kebede & Yamoah, 2009;Hailu et al, 2015) and in West African lowlands (Abe, Buri, Issaka, Kiepe, & Wakatsuki, 2010).…”

“…While reviewing the soil fertility potential for rice production in West Africa, Abe et al (2010) urged that appropriate soil pH should be maintained as micronutrient availability is greatly affected by soil pH. Furthermore, there should be sufficient nutrient supply in the soil and in particular sufficient supply of Zn in the MIS through Zn fertilizers to avert the negative Zn deficiency stresses.…”

Soil degradation reduces agricultural productivity and poses a great threat on food security status of households. In Kenya, farmers have for a long time been using only nitrogen and phosphorous based fertilizers oblivious of the soil fertility status. In most cases, there has been lack of plant response to these fertilizers, which could be due to a limitation of nutrients other than nitrogen and phosphorous. Soils are considered as variable natural bodies because of combined intrinsic and extrinsic factors of different intensities at a field or a larger region scale therefore an understanding of such variability is imperative to provide insights needed in their management. This study was thus initiated to assess the availability of soil micronutrients from rice growing Vertisols in the Mwea irrigation scheme. Top (0-15 cm) soil samples were collected across paddy fields in the irrigation scheme and analyzed for iron (Fe), zinc (Zn), copper (Cu) and manganese (Mn) by the 0.1 N HCl extraction method. Soil pH (water and 1 M KCl) was also measured using the glass electrode pH meter. Soil solution pH ranged from 4.56 to 8.05 and 3.33 to 6.63 for water and 1 M KCl respectively. Soil Fe, Zn, Cu and Mn concentration varied greatly and ranged from undetected to 1360.6, 0.12 to 8.00, undetected to 9.29 and 1.50 to 849.2 mg/kg respectively. Coefficient of variations (CVs) for soil micronutrients ranged from 64% to 154% indicating very high variability. Soil pH was least variable with CVs 12% and 15% for water and KCl respectively. These results imply that the paddy soils in Mwea region are highly heterogeneous and soil micronutrients are enriched in some areas and depleted in others due to farm management practices and soil properties. Averagely, soil available Zn was deficient across the scheme and as such Zn fertilization can be effective in increasing soil Zn concentration and availability in the soil-root interface further enhancing soil productivity and yield quality. Attention should also be paid to appropriate farm management practices to avoid accumulation or depletion of nutrients.

“…These values are lower in cultivated soils than the natural forests, but lowest in built-up areas. This may be dueto combination of lower C inputs into the soil after crop plants are harvested, losses in C due to bush burning, aggregate disruption arising from tillage and accelerated erosion [1], [2,[7][8][9][10][11][12][13]. Available phosophorus (P) was highest in fallow lands and lowest in built-up areas.…”

Soil quality variation in the tropical rainforest zone of Akamkpa upon conversion from the natural vegetation to other landuse types (natural forest, reforested lands, cultivated upland soils, swamps, soils around quarry sites, built-up areas and fallow lands) was evaluated with a view to ascertain the changes in physical, chemical and biological characteristics of the soils and determine to what extent these changes affects soil quality degradation rates and vulnerability potential. Surface soil samples were collected from four points in each landuse type at the depth of 0-15cm and mixed to obtain a composite sample for routine laboratory analysis of selected soil quality parameters. The soils were generally sandy loam to clay loam on the surface and lateritic clay at the subsurface. Bulk density varied from 1.12-1.48mgcm 3 , soil porosity was higher in cultivated soil (78.83%) and lower in the swamps (25.22%) water holding capacity was highest in swamps (72.9%) and lowest in the built-up areas (33.6%). Aggregate stability index was lower in the cultivated soils (0.44) and higher in the natural forest (0.69). pH value varied from 4.2-6.0, organic carbon levels were higher in the natural forest (9.84gkg) and lowest in built-up areas (4.16gkg -1 ). Total nitrogen varied from 0.42-0.72gkg, the value was lowest in built-up areas and highest in the natural forest soils. C:N ratio varied from 8.63-13.12. these values were lowest in cultivated soils than natural forest and reforested soils. Available P was highest in fallow lands and lowest in built-up areas. Exchangeable bases show variability across landuse types with calclium, potassium, ECEC higher in natural forest soils. Al 3+ , SAR, Fe, Mn, Cu and S higher were in soils around quarry mines than any other landuse type. Reforested lands, cultivated uplands and fallow lands showed a slight variability in the selected chemical parameters. The biological properties were highly correlated with soil quality status in response to landuse change types. Total microbial biomass was higher in reforested lands and lowest in built-up areas, while active microbial biomas was higher in fallow lands. Higher rates of qCO 2 :T for the cultivated soils, qCO 2 :A rates was higher for fallow lands. Resuts revealed that built-up areas and soils around quarry mines has a significantly ower SDR/VP than any other landuse type. Percentage soil quality rating was higher in the fallow land (88.0%), forested lands and reforested lands (83.3%), cultivated uplands (66.0%) swamps (56%), soils around quarry mines (44%) and built-up areas (33%). The findings suggest that the soils under fallow are slightly capable to resist degradation. Management practices such as planting leguminous crops, increased fallow period, organic manuring, planting of fast growing vegetative species and returning crop residues to the soil as a way of building up used carbon stocks.
