The decline in soil productivity amidst efforts to increase crop yield in Sub Saharan Africa (SSA) has made it imperative to assess the current fertilization management approaches. This study was conducted in two agroecological zones (i.e., Guinea Savannah (GS) and Deciduous forest (DF)) of Ghana to evaluate how different fertilization schemes in the long term (>5 years) impacted the soil Cited by: 4. Ghana, a country dominated by customary tenure, has not tested land consolidation as an option for enhancing agricultural development. Having regard to the complexities of customary tenure such as oral allocation, indeterminate boundaries and emotional attachment to land, it Cited by: Islands of dense forest in the savanna of 'forest' Guinea have long been regarded both by scientists and policy-makers as the last relics of a once more extensive forest cover, degraded and degrading fast due to its inhabitants' land use.

Recent studies show widespread encroachment of forest into savannas with important consequences for the global carbon cycle and land-atmosphere interactions. However, little research has focused on in situ measurements of the successional sequence of savanna to forest in Africa. Using long-term inventory plots we quantify changes in vegetation structure, above-ground biomass (AGB) and Cited by: economic sectors are crucial for economic development in Ghana.

This is because the area has many characteristics that could increase the chances of this happening. For example, the region is semi-arid, which means that it receives very little rainfall. Modelling the spatial distribution of plants is one of the indirect methods for predicting the properties of plants and can be defined based on the relationship between the spatial distribution of vegetation and environmental variables. In this article, we introduce a new method for the spatial prediction of the dominant trees and species, through a combination of environmental and satellite by: 9.

In the present study, we investigated the role of agriculture land use and farm management practices on soil organic carbon (SOC) storage in the savannah regions of northern Ghana. We evaluated selected land use types by using an integrated approach, involving on-farm interviews, community transect walks, land use monitoring, and soil by: It is recommended that fertilizer producing companies work closely with CSIR-SRI in the development and validation of fertilizer blends for up-scaling with smallholder farmers in the Forest-Savannah Transition and Guinea Savannah zones of Ghana, towards achieving improved cropland productivity for food security, poverty reduction and environmental sustenance. international tropical timber organization (itto) reducing deforestation and forest degradation and enhancing environmental services in tropical forests (reddes) small project document title rehabilitation of degraded forests for sustainable wood fuel production and climate change mitigation in the forest-savanna transition zone of ghanaFile Size: KB.

Savannah soil profile Savannah Soil. To obtain official soil series description, click here. The Savannah series consists of moderately well drained, moderately slowly permeable soils that have a fragipan.

These soils formed in loamy marine or fluvial terrace deposits. These nearly level to moderately steep soils are on uplands and terraces in.

Sheep and goats were farmed more semi-intensively in the forest zone compared to an extensive system in the savannah fringe.

A savanna or savannah is a mixed woodland-grassland ecosystem characterised by the trees being sufficiently widely spaced so that the canopy does not close. The open canopy allows sufficient light to reach the ground to support an unbroken herbaceous layer consisting primarily of grasses.

Savannas maintain an open canopy despite a high tree density. It is often believed that savannas feature. the catena, but, rather surprisingly, during the late afternoon and evening the riverain forest showed lower relative humidity than the middle-slope savanna.

A synthetic expression of the ecological conditions on the sites studied is given in Fig. 6 which compares the evaporation rates between stations and also between the two 24 h periods.

Savannas are characterized as areas connecting the equator forests and tropical deserts, with a wide range of vegetation in grassland, deserts and woodlands.

The biggest savannas are in South Africa, occupying 46 percent of the land in that area. Savanna soil types are determined by the climate they occupy, but are.

In association with food crops, pueraria can improve soil nutrient availability, stimulate soil biological activity, and control soil erosion, leading to high soil productivity. Under conditions in West Africa, pueraria has been shown to accumulate to kg N ha −1 within 4 to 18 mo of growth, of which 68% were derived from the.

Forest-savanna mosaic is a transitory ecotone between the tropical moist broadleaf forests of Equatorial Africa and the drier savannas and open woodlands to the north and south of the forest belt.

This paper investigates the mechanical properties of the concretionary laterites from the rain forest and the savannah zones of Nigeria.

This book examines the effects that land-use changes (notably agricultural intensification, logging, soil erosion, urbanization and mining) have on soil characteristics and processes in tropical and savannah environments.

It covers a range of geographical regions and environments as impacts of land use change are often site specific. This book brings together information on the contrasting characteristics, condition, present use and problems of the world's main natural grasslands.

Since grassland is commercialized through the grazing animal, particular attention is paid to the livestock production systems associated with each main type. Grazing resources are more than simply edible herbage: many other factors have to be.
