“…A lower soil pH may be due to addition of inorganic fertilizers (e.g. urea), loss of organic matter through erosion, and the leaching of basic cations as a result of seasonal flooding of the wetland (Nakamura et al, 2016;Agbeshie and Adjei, 2019). For rice production, the results obtained is suitable, considering that, upon reduction of the (top) soil following submergence, the pH tends to change towards neutral (pH 6.5-7.0).…”

The shallow and erodible soils of low fertility uplands have led to farmers extending their cultivable areas to wetlands for optimal crop production since these systems have the potential for exploitation in the dry season. To ensure its sustainable use, the physicochemical and the hydrological characteristics of the valley bottom should be ascertained. Studies were conducted to assess the suitability of wetlands for crop production by analysing the physicochemical properties of Besease wetland soils. Soil samples were collected from specific sites and profile pits for physical and chemical analysis in the laboratory. Field experiments were also conducted for soil physical properties. Soil textural analysis revealed that the average texture of the Besease inland valley was sandy loam with the distribution of sand, silt and clay as 55.42, 35.04 and 9.50%, respectively. Bulk density and moisture content on the field increased with depth in all profiles. Results of hydraulic conductivity using the mini disk infiltrometer ranged from 2 to 88.3 cm/day. The infiltration rate on the studied wetland ranged from 0.02 to 0.78 cm/min. The pH, OC, TN and CEC of the soil profile distribution for site P11-P14 obtained ranged from 6.9-4.6, 4.69-0.19%, 0.2-0.01%, 9-2.6 meq/100 g down the horizon respectively. The study unraveled a sustained plant nutrient availability and elongation of water level ponding which will result in increased water storage under rice cultivation in the studied wetland.

“…Additionally, the Consistency Ratio (CR) (7) which is an estimate of departure from consistency was used to validate the AHP pairwise matrix for relative criterion weight determination while The Consistency Index (CI) was calculated using (8): Therefore, CI = 0.45/5= 0.089. The Random index (RI) used to calculate the consistency ratios (CR) is shown in table 9 according to [17] where RI is Land Suitability for rice cultivation 1.24 (the number of criteria).…”

“…And (iii) Where are the most suitable locations for the cultivation of rice within the study area? The rise in global population, particularly in developing countries has notably resulted in an increase in demand for arable crops such as rice [8]. Improving the productivity of rice systems would hence bring about hunger eradication, poverty alleviation, national food security and economic development [4].…”

This research aimed at carrying out a land suitability analysis for non-rice cultivation areas in part of Ekiti state using a Geographic Information System based Analytic Hierarchy Process (AHP) approach with a view to ascertaining whether rice can grow in commercial quantities in other Local Government Areas that will lead to improving rice production in the State. To achieve the aim of the research, specific objectives were set, which were to (i) determine the land use/land cover within the study area, (ii) assess the climatic, soil, and topographic factors that pertain to rice cultivation, and (iii) carry out a land suitability analysis on rice cultivation. In this study, the Analytical Hierarchy Process method was used to combine land use/land cover, rainfall, temperature, slope, soil texture, and pH to produce a land suitability map for rice cultivation in non-rice growing areas of the study area. The research result shows that the spatial expanse of land unsuitable for rice cultivation in the non-rice cultivation area of Ekiti state was 1121.6 km2 which translated to 44% of the entire study area. Similarly, areas moderately suitable and suitable for the cultivation of rice were 529.1 km2 (21%) and 899 km2 (35%) of the study area respectively. Furthermore, the outcome of AHP validation showed that the consistency ratio was 0.07, which was less than the specified standard maximum value of 0.1, which signifies that there was a realistic degree of uniformity in the pairwise comparison. Based on the obtained results, it was discovered that: the built-up area in the study was only 5.2%, which signified that the remaining 94.8% of the study area was undeveloped and can serve agricultural purposes in the state. The land suitability map for non-rice cultivation produced for this study was detected to be a true representation of areas suitable for rice cultivation subject to overlay analysis and AHP validation. It was therefore recommended that this study can be used as vital background information for the improvement of rice production in Ekiti State Nigeria.

“…In comparing soil OC in the different land uses, the significant reduction in OC concentrations in the cropped and degraded soils in our current study could be due to accelerated decomposition resulting from high temperatures and tillage operations, superficial washing away of the topsoil by erosion, burning of biomass, and decreased inputs of litter (organic matter) [36,11]. Soils in Ghana are inherently poor in nutrient status [37,38] with farmers applying fertilizers in the maintenance of fertility. Despite the addition of organic manures and inorganic fertilizers on the cropped land in the study area, soil OC was still lower compared to that of the forested area.…”

Land use conversion significantly impact on sensitive soil quality parameters such as microbial biomass and soil microbial quotient. Therefore, soil microbial biomass and physicochemical properties were compared under three different land use systems namely agricultural land, degraded mine land and an adjacent natural forest in the Newmont Gold Ghana Limited concessional areas, Kenyasi, Ghana. In our field experimentation, an area of 300 m2 was demarcated in each land use type for soil sampling. In each of the land use type, we collected soil 5 samples at a depth of 0-15 cm in both the dry and wet seasons respectively. Parameters we measured included soil bulk density, pH, particle size distribution, organic carbon, total nitrogen, available phosphorus, microbial biomass carbon and nitrogen, and moisture content. Our results revealed that land use type significantly impacted on soil microbial biomass and physicochemical properties. Microbial biomass carbon and nitrogen was higher in the forested land compared to the agricultural land and degraded mine land, which was due to relatively higher amounts of litter inputs. Microbial biomass carbon decreased between 20.23 - 88.36% when land use changed from forested land to other land uses. Significant positive correlation was observed between soil microbial biomass and water content, soil organic carbon, phosphorus, clay, nitrogen. Generally, seasonal variation in our study area did not influence soil physical and chemical properties, however, it significantly affected microbial biomass indices. Findings of our study further revealed the importance of forested area in the maintenance of soil quality parameters.
