River Water Quality Assessment and Suitability for Irrigation in Northern Sudan Savanna, Ecological Zone of Nigeria (Published)

Good river water quality management and reusing the water appropriately in irrigation agriculture can decrease complete soil and crops toxicity, and serve as a potential feasible options to potable water as well as improvement of natural water resources shortages. This study was carried out between May and July, 2019 to investigate the discharge and irrigation reuse quality of Wudil River effluents in Kano State, Nigeria. The research was conducted in three locations of the river; locations A, B and C respectively. Water quality parameters; pH, COD, BOD5, nutrients (NO3-N, NH4-N and PO4-P), EC and SS were determined in different water samples obtained from the different locations. Data obtained were subjected to statistical analyses of variance (ANOVA). No significant variations (P>0.05) existed in all the chemical variables among the sampled locations. Comparison of the investigated parameters at the various locations of the river with the standard limit of discharge and irrigation reuse revealed that all the locations achieved compliance except for NH4-N and PO4-P variables that polluted the river using Food and Agricultural Organization (FAO), World Health Organization (WHO), United States Environmental Protection Agency (USEPA) and other related international standards. Hence, the need for a drastic move towards both discharge and irrigation water quality improvement of the river as well as environmental conservation through sustainable development and cleaner technology approach within the research area is highlighted.

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.
