Effects of Flooding On Soil Quality in Abakaliki Agro-Ecological Zone of South-Eastern State, Nigeria (Published)
The study focused on the Effects of Flooding on Soil Quality in Abakaliki Agro-ecological Zone of South-Eastern State, Nigeria, for proper soil and flood management to avert soil degradation. Soil samples were collected from three different floodplains and from arable land at the middle of the stream as control at the depth of 0-30cm, and were used for the determination of the selected soil quality. The treatments were replicated five times and data collected were analyzed using analysis of variance for complete randomized (CRD). All the soil properties assessed were significantly different (p<0.05) among the study locations. The results further showed that apart from sand, BD, gravimetric moisture that were higher in control, silt, clay and porosity were recorded highest mean values than control. Mean pH in floodplains recorded mean value of 5.9 being acidic than control with the mean of pH5.38. Also apart from Avail.P(38.50ppm),OC(1.89cmol/kg), Nitrogen (0.15cmol/kg), ECEC(18.16%) and BS(89.65%) being higher in control than floodplains, the mean of OM (2.5cmol/kg), Ca (10.5cmol/kg), Mg(4.7cmol/kg),K(0.14cmol/kg), Na(1.06cmol/kg) and EA(2.07) were higher in floodplains than control, which could support farming during flood cessation for increased food productions. Based on the results, it is recommended that flood best management practice should be encouraged in order to retain soil nutrients, reduce soil and water pollutions for ecosystem sustainability.
Constraints to Use of Soil Quality Maintaining Strategies in a Climate Change Stricken Area of Akwa Ibom State, Nigeria (Published)
The study assessed constraints to use of soil quality maintaining strategies among crop farmers in Ibesikpo Asutan Local Government Area of Akwa Ibom State, Nigeria. Multi-stage sampling technique was used to select 120 respondents for the study. Data were collected using interview schedule and analysed using descriptive and inferential statistical tools. Results show that 65.00% of the respondents were females. Majority (60.00%) were married, with 54.16% having household sizes of not less than 6 persons. Most serious constraints were inadequate finance and capital intensiveness of some strategies. Significant relationships existed between age (r2 = 0.152, p < 0.05), sex (c2 = 5.21, p < 0.05), household size (r2 < -0.212, p < 0.05) and constraints to use of soil quality maintaining strategies. There was significant difference in the extent of constraints to use of the strategies between male and female respondents (t = -1.12, p < 0.05). It is recommended that individuals should save funds for soil quality maintenance. Moreover, programmes aimed at reducing constraints to use of the strategies should be patterned according to severity of the constraints between male and female farmers.
