“…These pedogenic characteristics could be influenced strongly by the soil forming factors such as parent materials and organisms (including vegetation), Early pedogenic characteristics of soil may greatly be influenced by the chemical and mineralogical characteristics of the lithologic material; but other factors such as vegetation may be more influential on pedogenic processes over a period of time (Maniyunda et al, 2014). Vegetation ages and forms differ in the ways in which they cause differences in soil properties and have a tremendous effect on the soil quality and general sustenance of soil resource (Onweremadu and Peter, 2016). Changes in the ecosystem can influence soil properties via the release of exudates, decay of plant parts as well as their rooting activities (Quideau et al, 2001).…”

“…Plant species richness and nutrient recycling contribute to soil quality and its ecosystem functioning (Nielsen et al, 2011) due to varying transfer rates of litter fall components (Tate et al, 2011). Differences in soil properties and pedogenic characteristics among vegetal forms had been reported (Upadhaya et al, 2008;Onweremadu and Peter, 2016). Given that vegetation plays a substantial role in soil formation, it could be argued that some of the changes resulted from direct and indirect effects.…”

“…The climate of Owerri is characterized by two major wet and dry seasons. The area is also known for its deep porous soils which were obtained from sandy deposits in the coastal plains which are highly weathered and at the same time very low in mineral reserves and natural fertility [24].…”

The gains obtained from organic mulching of pineapple farms can never be overemphasized. Despite this fact many developed countries still patronize synthetic mulching due to its efficiency in large pineapple farms. However in developing countries of Africa and Nigeria in particular where small scale pineapple farmers still contribute to the national gross domestic product (GDP), the need for cheaper organic mulching techniques which do not only suppress weed and improve soil fertility but have positive influence on pineapple flowering, ripening and suckering is required. Based on this, a research was carried out at the Teaching and Research Farm, Federal University of Technology Owerri to assess the effect of some selected organic mulch types on the maturing trends of Smooth Cayenne pineapple. A 32 factorial fitted into a Randomized Complete Block Design (RCBD) with three replications was used. Result showed that main effects from mulch rates and mulch types independently had significant influence on days to first flowering, days to 50% flowering, the interval between time of first flowering and attainment of 50% flowering, days to ripening, interval from flowering to ripening and number of suckers produced at 50% flowering stage while interaction of mulch rates and mulch types only had significant effect on days to first flowering. This study revealed that the utilized organic mulch materials had tremendous positive influence on flowering, ripening and suckering of Smooth Cayenne pineapple.

“…It has annual temperature of 25 °C to 28 °C and relative humidity of about 85 % depending on the season of the year. The soils of the study area are derived from the coastal plain sand and alluvium from deltaic marine deposits (Onweremadu and Peter, 2016). The vegetation of the study area is the humid tropic rainforest vegetation that has been drastically altered due to crude oil pollution and excessive deforestation.…”

The research was carried out in Bodo city in Gokana Local Government of Rivers State, Southern Nigeria to evaluate the land suitability for rubber and cashew cultivation using the relevant land suitability guidelines for the cultivation of the two cash crops of interest. Mapping of the 100 ha of land in Bodo city was done using the rigid grid method of soil survey. The three mapping units (summit, middle slope and valley bottom) were identified and delineated. Three representative soil pedons of 2 m x 2 m x 2 m were dug and described by horizon from top to bottom (0 cm to 200 cm). Soil samples were collected from identifiable horizons and processed for laboratory analysis using standard routine laboratory methods most appropriate. The results showed that pedons 1 and 3 covering 86,000 ha of the entire study area were found to be moderately suitable for rubber cultivation with limitation in soil physical characteristics (texture) and fertility (low base saturation < 50 %). Pedon 2 covering 14,000 ha of the total land of the study area was marginally suitable due to limitation in soil fertility (low base saturation < 80 %). Pedon 1, 2, and 3 were also moderately suitable for cashew cultivation in the study area with limitation in soil physical characteristics (texture) and fertility (low organic carbon), while limitation in wetness (poor drainage) was peculiar to pedon 3 only. Thus, soils in the study area were moderately suitable for both rubber and cashew cultivation in the area.
